I have been receiving regular spear phishing calls from these guys, or someone who bought the leaked data, with classic tactics like claiming that I need to confirm a potentially fraudulent transaction. They speak perfect English with an American accent, sound very friendly, and have knowledge of your account balance. Thankfully on the first call I realized it was a scam right away, and Google's call screening feature takes good care of the rest. Wish I could forward them to Kitboga[1].
I guess they didn't have as much luck as they wanted scamming Coinbase's customers, and once they had their fun they decided to try extorting Coinbase themselves.
If you had any significant assets on Coinbase at any time prior to this breach, spear phishing is the least of your worries.
Coinbase not only leaked your full name and address, they also gave up your balances, your transaction history, and images of your government identification.
People with "significant" crypto balances are being assaulted on the street and in their own homes, and family members are being kidnapped for ransom.
"Significant" in this case can be $10k or less.
Until now, your best defense secrecy. Never talk about crypto in public in any way that could be traced to your real-world identity.
Thanks to Coinbase that defense is now gone.
The bad guys can see who has ever had a significant balance on Coinbase (even if they don't right now), whether that balance was sold for cash and how much, or if you've ever transferred tokens off the exchange to a self-custody wallet.
Now the bad guys know who's worth kidnapping for ransom and where you live. For most people, a Google search of your name and home address turns up the names of family members who would would also be lucrative targets for kidnapping and threats of violence.
Coinbase will never be forced to reimburse all the damage they've done because the true cost would bankrupt the company.
Companies should seriously consider implementing GDPR even in the US, it certainly made taking data dumps of customer data a lot harder and certainly private images like Government IDs were encrypted on disk. I’m surprised at the lack of security if I’m honest, at Yahoo! almost nobody had access to prod user data.
Essentially you cannot trust Coinbase IMO, might move the few hundred dollars of BTC out of there :-)
But hey, at least by being forced to give crypto exchanges all our personal details we're all super protected from the four horsemen: money laundering, drugs, terrorism and pornography.
> People with "significant" crypto balances are being assaulted on the street and in their own homes, and family members are being kidnapped for ransom. "Significant" in this case can be $10k or less.
I wonder why, select a person completely at random and by median you'll get just as much from what they have sitting in their checking account. Select a nicer area for an order of magnitude more. That's not encouragement to go assault people in their homes or kidnap families... just confusion.
Why do you see this as the fault of Coinbase? Do other companies somehow have employees that are immune to bribes and blackmail?
This is due to US Government KYC laws that forced Coinbase to associate government identification with all accounts. No crypto company required ID until they were forced to.
It’s my biggest gripe. They can pretty accurately flag a number as Spam or Telemarketing but in the “Silence Unknown Callers” setting I can only silence every single unknown caller. I can’t silence every single number that’s not in my contacts. When the plumber calls to confirm he’s in route, my phone needs to ring. Stuff like that.
Unfortunately blocking all unknown calls is the only way to sanity. Otherwise we're talking 6-9 calls coming in ALL DAY, EVERY DAY.
The calls are coming from new numbers, across multiple area codes. A few months ago I would have advised using Begone (https://apps.apple.com/us/app/begone-spam-call-blocker/id159...) to block but that only worked since these calls were isolated to blocks of area codes that were pretty safe to block like 888-XXX-XXXX, but now ZERO of these calls are using a fixed area code that would be relative safe to block.
Yeup, I finally broke down went from Android -> IPhone 16 Pro. I like a lot about Apple's personal security policies for their consumers vs Google, but damn, I miss google's automatic call spam detection and management. All day long my Apple phone rings, and I just have to ignore the calls.
iPhone user here. I put on airplane mode unless I'm making or expecting a call. Otherwise, I make it clear that email is my primary form of communication.
> I have been receiving regular spear phishing calls from these guys, or someone who bought the leaked data, with classic tactics like claiming that I need to confirm a potentially fraudulent transaction.
And how long has this been at an increased level? Because i'm not buying the coinbase narrative that they thought this was a systemic issue until they were contacted by the 'cybercriminals'.
It started around the beginning of April, at the same time as I got an initial email from them about my account information being accessed. Which I'm thinking is probably the same breach as they're talking about here.
Oh yeah I get the Microsoft account emails, and Instagram ones, randomly (I have an account but never use it). I'm pretty sure SMS 2FA is turned off on my Coinbase account, which is highly recommended.
Where was the number from? I received an impressive number of phonecalls attempt but thankfully I never answer to unknown numbers. With google call screen they hung up everytime so I assume its a scam.
Scams have gotten better since AI. Most of the common spelling mistakes are gone.
I was looking through some phishing e-mails the other day out of curiosity and found a weird unicode character mistranslated. Immediately knew it was an artifact of bad translation. So they're not perfect, but they're damn good.
The problem is that it seems like the data that leaked is also the data that would be used to do account recovery.
And what that means is that
1) If you lose access to your account (through either your own fault, or coinbases fault) that the process of recovering it may not be so straightforward anymore.
2) Hackers can try to “recover” accounts now using this leaked info.
This is a huge problem. What coinbase needs are IRL offices where you can go and do things like account recovery, and where people trying to steal money can be caught and prosecuted (and makes a huge barrier for the overseas thieves who are usually doing this)
The only solution here is: hardware 2 factor like yubikeys.
One that I'm using does, but I find it extremely annoying when they have me go to a branch to unblock my account that they locked due to a poorly calibrated risk system (that they need due to not supporting actually secure 2FA methods).
Coinbase is identical to a bank because it holds customer funds. Your comment isn't quite the dunk you think it is. Blockchains allow money to be held anonymously without any banks involved. Centralized exchanges are just profiting on speculation and probably should be banned.
If you ever sent money to or from a wallet you control, I'd think a reliable recovery factor would be to use that key to sign a message that Coinbase can verify with the address in their records. Cryptocurrency after all is just another PKI.
> What coinbase needs are IRL offices where you can go and do things like account recovery, and where people trying to steal money can be caught and prosecuted
People getting locked out of their account (which can happen due to no fault of the user, e.g. by an overly nervous risk system) will be really happy to have to potentially travel to a different city to regain account access...
Fine, make it optional. I actually would love a version of cold storage that is: never release this money unless I personally travel to an office if NYC and authorize it.

Watching crypto enthusiasts run into every problem that society already tackled with in the past when developing currency and its controls, and then coming up with solutions that look exactly the same as what dirty fiat currency uses, has been a source of much entertainment the past few years
I tried to reach out to coinbase customer support to see if I was impacted. Once I wasted my time with the AI bot and got a human they were unaware of the breach. I was the first person to inform them about it.
I don't believe they did, and I also believe they have known about this issue for a long time, and they should have been required to disclose their mandatory 8k a lot earlier.
Coinbase seems to be going to great lengths to try and distance themselves from the so-called "rogue overseas support agents".
If they were Coinbase employees or contractors, that means the company basically sold its own data to hackers, who then turned around and demanded a ransom.
Reimbursing duped customers makes sense, as it seems like they would have a pretty straightforward case to make in court that Coinbase's actions led to their loss.
I'm more curious if someone who feels the need to move, change banks, change their email, hire a security detail etc. could successfully sue the company to recover some or all of those costs.
>If they were Coinbase employees or contractors, that means the company basically sold its own data to hackers, who then turned around and demanded a ransom.
This seems like a strange interpretation. If an employee at your company, against policy and likely illegally extracts proprietary data and gives it to hackers in exchange for money you can hardly say that "My company sold it's data".
I agree it wasn't authorized, but I should absolutely still be able to hold the company responsible for the damage. My business relationship is with you, not your employees or vendors.
They in turn could go after the perpetrator. If they're using contractors who are cheap, unvetted, untrustworthy or don't carry liability insurance that's their problem and shouldn't excuse them of accountability.
In a way you can. A company is its employees. If you want employees with integrity you might need to pay better than bottom dollar employees from the cheapest countries possible.
I once applied for a bank position, and they wanted to run a credit check. If you're in a position of handling money, the company has a responsibility to vet its employees. Do I agree with credit checks? Absolutely not, but the point is, Coinbase is partially responsible and that's why they're refunding duped customers.
How far that responsibility goes is up for debate.
> This seems like a strange interpretation. If an employee at your company, against policy and likely illegally extracts proprietary data and gives it to hackers in exchange for money you can hardly say that "My company sold it's data".
When an employee ships a new feature, do you say "My company shipped a new feature?"
> We will reimburse customers who were tricked into sending funds to the attacker due to social engineering attacks. If your data was accessed, you have already received an email from no-reply@info.coinbase.com; all notifications went out at 7:20 a.m. ET on 5/15 to affected customers.
The no-reply is an interesting decision. I get how difficult it is to run a company like Coinbase (their biggest strength, centralized + customer support, is also what enables this social engineering), but feels like an odd choice.
Their "customer support" includes not expecting users to set up PGP to communicate with them. Email is not a secure method of communication by default.
It's fine to send a notification instructing them to visit the secure portal for more info, though. Hence, no-reply.
no-reply is a good practice. No business should ever encourage their customers to reply to the emails they are sending out. That's what scammers do.
To contact the company you should go to company website at the address you know (which shouldn't be given in email as well), log in and send a message through internal message system, possibly referring to the email that you recieved through a random code (those can be auto-suggested if they recently tried to contact you by email).
If you do anything else your communication knwowingly mimics communication of a scammer.
Unrequested email should always only be one way communication. Email is too untrustworthy for it to be anything more.
> No passwords, private keys, or funds were exposed and Coinbase Prime accounts are untouched.
I'm curious why no Coinbase Prime accounts were part of the leak (assuming that's what they mean). Is there some sort of additional layer of data protection behind the Coinbase Prime paywall? Or perhaps those accounts were intentionally avoided as they would presumably belong to more savvy users.
Coinbase Prime is its own exchange with its own support (actual humans in the USA that are available to chat to). It's for "institutional investors" so unavailable to most customers without the proper credentials/paperwork. They don't share the same outsourced "support" as the regular exchange, which appears to be the attack vector here.
And the reason Coinbase has to keep all that sensitive stuff, much more than what would be required to identify and authenticate you, which you hope will never be stolen, is because of know your customer laws, so you can thank your government that pictures of your passport got stolen and for whatever criminals and rogue Coinbase employees do with that info.
There are very good reasons for KYC, the problem here is not the government regulation, it's once again private companies being sloppy with their customer's data because sloppy is cheap and it's not their info on the line, it's yours, so there's little motivation for them to safeguard it _unless_ they're compelled to do it by law.
The people who designed a government regulation to deputize private companies couldn't possibly have known how sloppy private companies are with other people's data?
They could have designed KYC to minimize long-term storage requirements etc at some cost to what they could enforce, but a government like the US is inherently sloppy with the rights that are reserved for parties besides itself.
> And the reason Coinbase has to keep all that sensitive stuff, much more than what would be required to identify and authenticate you, which you hope will never be stolen, is because of know your customer laws
Real cop out here, be honest. Why should every single agent have access to your identity documentation (which is only required for KYC) in perpetuity?
Whatever you think of Coinbase, this is a pretty good response IMO:
> and will not pay the $20 million ransom demand we received. Instead we are establishing a $20 million reward fund for information leading to the arrest and conviction of the criminals responsible
I’d say the better thing for customers would be to pay the ransom demand and get the PII back. If they want to fund a reward scheme too, well great, but if it were my data, I’d care more about Coinbase limiting the breach of the data, not playing around with retaliatory rewards.
There is no guarantee that an anonymous criminal is going to hold up their end of the agreement. Coinbase has no idea who they're negotiating with or where that data has been shared.
That, and they're reimbursing customers who were tricked.
I love it. This also would have been a great opportunity to break out of corporate speak for a moment for a good “Up yours hacker assholes!” Even us folks in the Bible Belt appreciate a well timed swear word here and there.
> Instead we are establishing a $20 million reward fund for information leading to the arrest and conviction of the criminals responsible for this attack.
I’m not usually a huge fan of crypto folks, but I applaud this.
I hope they are serious about paying the reward, and aren’t planning to rug-pull it.
It might not be a bad idea for the various crypto exchanges to pool their resources into a non-denominational security organization. It could offer hardening services, and some kind of accreditation.
It would also make many Ponzi schemes easier to spot, as they wouldn’t want to contribute.
> recruited a group of rogue overseas support agents
Why not just say what country the are from and how they hired them to start with. It's presented as those sneaky "overseas" people that somehow got access to our systems. This company makes what, a few billions in revenue but they couldn't vet and hire the right people?
I'm having de ja vu here. If they only found out when they attempted to extort them does it mean they don't even bother to log employee access? Is there any means for accountability at all internally?
It would be so simple to have access tracking and flag or lock out rogue employees... I look forward to seeing what the golden parachutes look like.
Looking at their blog post, it seems like they paid customer support agents to hand over sensitive data. The attackers did not have access to any agent accounts themselves, and the customer service agents were accessing data they were already privileged to anyways.
The customer service agents were accessing data they were already privileged to anyways.
That's not how front line support agent access should work. You get access based on active cases you are working on, not the keys to the kingdom because you might need to support a member at some future point in time.
It makes me wonder what type of access support agents have in the first place. A lot of this information should require "unlocking" on a case-by-case basis by challenge/response while interacting with a customer.
I built the admin panel used by internal employees and contractors at a major fintech payments processor (PCI Level 1). We had to add multiple levels of safety once we decided to hire a team outside of our US office including logging, monitoring and also rate-limiting (ask for manager to approve if more than 5 full details requests, etc.)
I think these requirements are much stringent due to PCI-DSS standards for credit card processors. I wonder if a lack of such standards in crypto makes the companies holding customer funds more lax.
Logging and retroactive auditing seems like the very least they should do. Even asking the customer service agent to first provide identifying details of the customer they can't easily know or guess by themselves doesn't seem excessive, given the sensitivity of the information.
It won't work for 100% of all calls (what if the customer is locked out themselves etc.), but those calls can then be handled by even more closely monitored agents.
"Less than 1% of monthly transacting customers" means up to 1% were accessed – that seems very high, i.e. much higher than the number of customer service contacts I'd expect.
So this is probably why the phishing calls have increased from ~1 per month to ~3 per week.. good to know... Wish coinbase would let me DO something about it... Maybe fresh accounts for everyone? Maybe KYC data not directly linked to accounts? There should be SOMETHING they can do because the sheer volume of people constantly harassing CB customers is nuts.
> So this is probably why the phishing calls have increased from ~1 per month to ~3 per week.
Yes and their timeline doesn't add up with what they disclosed. If you take the Coinbase narrative, they only believed this was a 'material' issue once contacted by the hackers for a $20m demand, they weren't able to put the pieces together themselves.
The phishing has been elevated for weeks, especially via text message, and their lack of internal controls for access and monitoring are clearly severely lacking.
When i get those calls, i usually tell them “why dont i just save everyones time and just give you my bank account number, password and social security number? That sound good?”
There should be an ISO standard with respect to how much power and information that front line customer support agents have. The more information you need, like changing passwords or accessing personal information, should get forwarded to higher level customer support agents with better training and more monitoring. This way you can design customer support experience with as little exposure to security issues as possible.
The CS reps are based in a LCOL country so the opportunity for theft is simply incredibly lucrative.
What is really needed, is customer-in-the-loop for access to their data. The problem is, not all accesses would make sense. Doing analytics over the data of the top 1% of customers, for example, requires some level of access, but would freak out those customers if they had to approve it.
They main defense against internal attacks is bookkeeping. Banks have been dealing with this for thousands of years. I recommend the corresponding chapter in Security Engineering by Ross Anderson: https://www.cl.cam.ac.uk/archive/rja14/Papers/SEv3-ch12.pdf
Maybe it’s a naive question, but in many breach reports I see things like 'No passwords, private keys, or funds were exposed.' How come companies can usually protect that kind of data, but not emails, names, and other personal info?
Companies want the ability to use things like emails, names, and other data for user experiences (go to settings, see name and change it), advertising (target this address book for X ad), etc. So these are typically plaintext (oversimplified) and accessible by different systems while passwords or private keys have one use case only and can have a higher bar of protection.
Such data is typically encrypted and purely write-only, only read by the system itself. Thus it is only exposed if the database itself is exposed. If the leak was compromise of the systems that access the data (which appears to be the case here--insiders copied data they could access) the write-only info is not exposed.
A properly implemented login system will never store a password in the first place. Properly hashed passwords can still be cracked in some cases, but if your password is strong and the hash is good, it’s safe.
The article says they sent an email, but I usually ignore emails from Coinbase. I hope there's going to be a better way to find out if your data was breached. I was locked out of my account before, and had to upload an ID. I thought they didn't store it... :o
I’ve been getting scam texts from scammers who claimed my Coinbase account was compromised and to contact them. I wonder if this incident was the root cause
> less than 1% of Coinbase monthly transacting users
Unclear if users whose data was stolen, but did NOT transact in the last month are included in this statistic. Feels like a very intentional phrasing on their part
I wonder what percentage of Coinbase's (but also any other company storing PII data) support is done by AI at this point, and whether they could focus on and invest much more heavily to make that as close as possible to 100%.
>On April 12, Coinbase updated their user agreement to take effect TODAY, May 15, with new language about waiving some rights to class action lawsuits and jurisdiction selection.
Also, "Coinbase had detected the breach independently in previous months", aren't they required to disclose this? In the EU they are: Every EU institution must do this within 72 hours of becoming aware of the breach, where feasible
What they got
- Name, address, phone, and email
- Masked Social Security (last 4 digits only)
- Masked bank‑account numbers and some bank account identifiers
- Government‑ID images (e.g., driver’s license, passport)
- Account data (balance snapshots and transaction history)
Wow. Why does customer support staff have access to images of the user's passports?
I also like 'last 4 digits only' as if that's not the most important parts and the part so many places use to validate your identity, the first 5 are just area and group so they're not exactly random.
Everyone's social security number is available. If you go download the leak referring to in this HN post [1], your SSN is certainly in it. Mine was, everyone in my family's was, almost all of my friends' were.
The world needs to stop pretending that SSNs are secret. They aren't.
Who else would verify the user passports if not the customer support staff? Who verifies (and photocopies! in Asia and Europe) your passport at a hotel or car rental office?
The attackers bribed customer service agents to hand over data and documents, they were not breached directly. It's possible this stuff may have been handed over before being destroyed.
CS can validate without knowing the details, the same way you don't enter a password and then check to see if that matches the password in the system.
The fact that they keep blaming overseas customer support is pure blame shifting - you still hired someone and gave them access to all this data, Coinbase!
Isn't the whole point of crypto to keep PII out of it completely? If not, what is all this non-sense for exactly, other than the typical goals of pyramid schemes?
Yes, but I do think an organization like Coinbase or a cell phone carrier - which are extreme targets of fraud - have an obligation to recognize that their employees are targets and implement greater security measures than most organizations. Maybe Coinbase should even pay higher wages and use onshore customer service agents.
You can take the Google approach of basically not empowering the agents at all. It's not worth trying to social engineer Google CS, because they can't do anything anyway.
Let me add to your statement. It is hard to keep call center workers bribe-proof WHEN they are paid peanuts AND they are working for a company that is in an extremely high risk business of managing crypto.
The odds are already against their future viability after a breach like this and if they're fumbling the response this bad it really doesn't bode well for them.
They would have been better off not even bringing up their location if they weren't going to be transparent.
> Coinbase didn't adequately secure sensitive customer information, and it was leaked
Practically every company has someone with credentials who is in some combination of debt, a damningly-adulterous relationship, a damningly-illegal substance relationship and/or feels underappreciated or slighted compensationwise. The question is generally how much it costs.
Which is exactly why insider threats should be explored as a threat-model and mitigated to make the blast radius as small as possible via rate PII sanitization, access controls, access monitoring, rate limiting, etc.
Bribes are one thing, but threats could also happen. This is a big part of the reason why I absolutely hate entities that think residential addresses should be public record.
This is a precedent to Coinbase employees getting physical threats at their door just because e.g. some voter registration, utility company, bank, credit card, or court record decided to release their name and addresses on the internet. People could show up at some Coinbase software engineers' apartment doors with guns demanding they send BTC to arbitrary addresses.
AFAICT it's impractical to keep residential addresses 100% private/secure - too many ways to get an address from any number of companies, organizations and governments that collect it for various reasons.
Plus numerous ways to infer your address from other data sources, including apps that grab GPS on friends' cellphones when they visit, etc.
Finally, shutting down paid data brokers seems virtually impossible in practice, which means anybody googling you can pay $20 and get everything.
Remember, the issue isn't lazy goodguys but even slightly motivated badguys, who then use third party scripts to do the data collection.
It's not surprising. Coinbase is nothing but a money laundering exchange, just like every other sketchy crypto exchange out there. They were also engaged in pump and dump of various altcoins

What date did this news come out? I see it just happens to be the same date as mentioned in this email, May 15. Coinbase sneakily is trying to prevent their customers from exercising their legal rights. If you work for Coinbase, you ought to be ashamed and quit. If you use Coinbase, remove all your assets immediately.
I'm open to hearing reasons why this is just a coincidence or I'm misinterpreting the situation. Please, go ahead.
It will happen (at least attempted) with on-shore support staff too, My next door neighbour used to work for a UK high street bank and even there support staff were approached, with some of them first befriended, and eventually bribed in to passing along PII. No doubt it happens in the US too. Just costs the bad guys more.
> The company said the hacker stole customer names, postal and email addresses, phone numbers, and the last four-digits of users’ Social Security numbers. The hacker also took masked bank account numbers and some banking identifiers, as well as customers’ government-issued identity documents, such as driver’s licenses and passports. The stolen data also includes account balance data and transaction histories.
I mean... wasn't coinbase sort of scammy to begin with? Several years ago I gave them some USD, turned it into BTC, saw the value of the BTC go up, but when I tried to cash out was told that wasn't a thing that was supported by their platform. Later I was told I could apply for a $399/year credit card and could partially pay off the balance with BTC sale proceeds. I'm sure this was all disclosed somewhere in the terms of service I clicked through, and I only lost $1000 to their scheme.
But I've always wondered why people think this is how investment vehicles work. I monkeyed around with stock market bets and even Robin Hood allows you to cash out of your positions.
I dunno why you had problems, but I've been using Coinbase with no problems at all for years. It's linked to my bank account, so if I want to pay for something with bitcoin, I can easily buy and send bitcoin with just a few clicks. I don't invest or speculate in bitcoin, so I only maintain a small account balance. And selling bitcoin and transferring the proceeds to my bank account has been just as easy and trouble-free.
It's more likely you didn't "lose" $1k, but that you had "missed profits". And if you missed the profits because you didn't verify yourself earlier for withdrawal, then that's on you.
Coinbase supported direct bank withdrawals well before they launched their crypto debit cards.
It's really unfortunate that KYC regulations required Coinbase to have this information in the first place. We should be establishing strong social norms against sharing PII without a legitimate reason; this is not just an individual theft risk but a national security risk. Coinbase doesn't pay into your Social Security account, so they shouldn't have your Social Security number. They don't visit your house, so they shouldn't have your address. Etc.
Historically, although KYC regulations were widespread in Communist countries, they were unthinkable in most democratic countries until 9/11, which provided spy agencies with their golden chance to write their wishlist into law. But unfortunately that helps foreign spy agencies just as much as, maybe more than, it helps domestic ones.
You seem to believe that AML/KYC regulation exists to benefit customers or to prevent or recover from account compromises. It does not, and I have no idea why you would think it does. Something like a Yubikey or iris-scanning stations could help to prevent Coinbase account compromises, but AML/KYC regulations do not require or even encourage them, though perhaps someday they will.
Under specific conditions, the client can communicate with malware already on device, save data locally for other software to pick up, or downright stream the decrypted software to a third party.
Most likely is to introduce a flaw in the client that can be used by other walware on the client.
Roll out an update that defeats the end to end encryption in some subtle way that wouldn't go noticed for a few days. They'd be told when to do it for maximum effect, and if the window is small enough it might even go unnoticed for far longer when another uncompromised update overwrites it. They have no duty to report such things to relevant authorities even if it was discovered internally, so you could be looking at some corporate coverup that while not in on it, seeks to minimize liability/embarrassment.
Really, can you possibly tell if your Signal messages were compromised? Now that iPhones aren't really jailbreakable, you can't even see inside your own device.
I have been receiving regular spear phishing calls from these guys, or someone who bought the leaked data, with classic tactics like claiming that I need to confirm a potentially fraudulent transaction. They speak perfect English with an American accent, sound very friendly, and have knowledge of your account balance. Thankfully on the first call I realized it was a scam right away, and Google's call screening feature takes good care of the rest. Wish I could forward them to Kitboga[1].
I guess they didn't have as much luck as they wanted scamming Coinbase's customers, and once they had their fun they decided to try extorting Coinbase themselves.

If you had any significant assets on Coinbase at any time prior to this breach, spear phishing is the least of your worries.
Coinbase not only leaked your full name and address, they also gave up your balances, your transaction history, and images of your government identification.
People with "significant" crypto balances are being assaulted on the street and in their own homes, and family members are being kidnapped for ransom.
"Significant" in this case can be $10k or less.
Until now, your best defense secrecy. Never talk about crypto in public in any way that could be traced to your real-world identity.
Thanks to Coinbase that defense is now gone.
The bad guys can see who has ever had a significant balance on Coinbase (even if they don't right now), whether that balance was sold for cash and how much, or if you've ever transferred tokens off the exchange to a self-custody wallet.
Now the bad guys know who's worth kidnapping for ransom and where you live. For most people, a Google search of your name and home address turns up the names of family members who would would also be lucrative targets for kidnapping and threats of violence.
Coinbase will never be forced to reimburse all the damage they've done because the true cost would bankrupt the company.

Companies should seriously consider implementing GDPR even in the US, it certainly made taking data dumps of customer data a lot harder and certainly private images like Government IDs were encrypted on disk.

Essentially you cannot trust Coinbase IMO, might move the few hundred dollars of BTC out of there :-)

Why do you see this as the fault of Coinbase? Do other companies somehow have employees that are immune to bribes and blackmail?
This is due to US Government KYC laws that forced Coinbase to associate government identification with all accounts. No crypto company required ID until they were forced to.

It’s my biggest gripe. They can pretty accurately flag a number as Spam or Telemarketing but in the “Silence Unknown Callers” setting I can only silence every single unknown caller. I can’t silence every single number that’s not in my contacts. When the plumber calls to confirm he’s in route, my phone needs to ring. Stuff like that.

Unfortunately blocking all unknown calls is the only way to sanity. Otherwise we're talking 6-9 calls coming in ALL DAY, EVERY DAY.
The calls are coming from new numbers, across multiple area codes. A few months ago I would have advised using Begone (https://apps.apple.com/us/app/begone-spam-call-blocker/id159...) to block but that only worked since these calls were isolated to blocks of area codes that were pretty safe to block like 888-XXX-XXXX, but now ZERO of these calls are using a fixed area code that would be relative safe to block.

> I have been receiving regular spear phishing calls from these guys, or someone who bought the leaked data, with classic tactics like claiming that I need to confirm a potentially fraudulent transaction.
And how long has this been at an increased level? Because i'm not buying the coinbase narrative that they thought this was a systemic issue until they were contacted by the 'cybercriminals'.
It started around the beginning of April, at the same time as I got an initial email from them about my account information being accessed. Which I'm thinking is probably the same breach as they're talking about here.
I started getting regular Coinbase login confirmation codes text messages with no attempts on my end
Same with my Microsoft account actually
I usually just ignore it but I assume someone is testing if my email can be used to login.
Oh yeah I get the Microsoft account emails, and Instagram ones, randomly (I have an account but never use it). I'm pretty sure SMS 2FA is turned off on my Coinbase account, which is highly recommended.
Where was the number from? I received an impressive number of phonecalls attempt but thankfully I never answer to unknown numbers. With google call screen they hung up everytime so I assume its a scam.

The problem is that it seems like the data that leaked is also the data that would be used to do account recovery.
And what that means is that
1) If you lose access to your account (through either your own fault, or coinbases fault) that the process of recovering it may not be so straightforward anymore.
2) Hackers can try to “recover” accounts now using this leaked info.
This is a huge problem. What coinbase needs are IRL offices where you can go and do things like account recovery, and where people trying to steal money can be caught and prosecuted (and makes a huge barrier for the overseas thieves who are usually doing this)
The only solution here is: hardware 2 factor like yubikeys.
The Crypto industry continues their speedrun of rediscovering all of the reasons for why the global financial system exists.

Many banks don't have physical branches.
One that I'm using does, but I find it extremely annoying when they have me go to a branch to unblock my account that they locked due to a poorly calibrated risk system (that they need due to not supporting actually secure 2FA methods).
Coinbase is identical to a bank because it holds customer funds. Your comment isn't quite the dunk you think it is. Blockchains allow money to be held anonymously without any banks involved. Centralized exchanges are just profiting on speculation and probably should be banned.

I don't believe they did, and I also believe they have known about this issue for a long time, and they should have been required to disclose their mandatory 8k a lot earlier.

Maybe the actual first person got unlucky with a lazy customer support agent.
You were read "Wow we didnt know about it, you are the first person talking about it to me" script line.
Coinbase seems to be going to great lengths to try and distance themselves from the so-called "rogue overseas support agents".
If they were Coinbase employees or contractors, that means the company basically sold its own data to hackers, who then turned around and demanded a ransom.
Reimbursing duped customers makes sense, as it seems like they would have a pretty straightforward case to make in court that Coinbase's actions led to their loss.
I'm more curious if someone who feels the need to move, change banks, change their email, hire a security detail etc. could successfully sue the company to recover some or all of those costs.
>If they were Coinbase employees or contractors, that means the company basically sold its own data to hackers, who then turned around and demanded a ransom.
This seems like a strange interpretation. If an employee at your company, against policy and likely illegally extracts proprietary data and gives it to hackers in exchange for money you can hardly say that "My company sold it's data".
I agree it wasn't authorized, but I should absolutely still be able to hold the company responsible for the damage. My business relationship is with you, not your employees or vendors.
They in turn could go after the perpetrator. If they're using contractors who are cheap, unvetted, untrustworthy or don't carry liability insurance that's their problem and shouldn't excuse them of accountability.
In a way you can. A company is its employees. If you want employees with integrity you might need to pay better than bottom dollar employees from the cheapest countries possible.
I once applied for a bank position, and they wanted to run a credit check. If you're in a position of handling money, the company has a responsibility to vet its employees. Do I agree with credit checks? Absolutely not, but the point is, Coinbase is partially responsible and that's why they're refunding duped customers.
How far that responsibility goes is up for debate.

The no-reply is an interesting decision. I get how difficult it is to run a company like Coinbase (their biggest strength, centralized + customer support, is also what enables this social engineering), but feels like an odd choice.
Their "customer support" includes not expecting users to set up PGP to communicate with them. Email is not a secure method of communication by default.
It's fine to send a notification instructing them to visit the secure portal for more info, though. Hence, no-reply.

no-reply is a good practice. No business should ever encourage their customers to reply to the emails they are sending out. That's what scammers do.
To contact the company you should go to company website at the address you know (which shouldn't be given in email as well), log in and send a message through internal message system, possibly referring to the email that you recieved through a random code (those can be auto-suggested if they recently tried to contact you by email).
If you do anything else your communication knwowingly mimics communication of a scammer.
Unrequested email should always only be one way communication. Email is too untrustworthy for it to be anything more.

> No passwords, private keys, or funds were exposed and Coinbase Prime accounts are untouched.
I'm curious why no Coinbase Prime accounts were part of the leak (assuming that's what they mean). Is there some sort of additional layer of data protection behind the Coinbase Prime paywall? Or perhaps those accounts were intentionally avoided as they would presumably belong to more savvy users.
Coinbase Prime is its own exchange with its own support (actual humans in the USA that are available to chat to). It's for "institutional investors" so unavailable to most customers without the proper credentials/paperwork. They don't share the same outsourced "support" as the regular exchange, which appears to be the attack vector here.
And the reason Coinbase has to keep all that sensitive stuff, much more than what would be required to identify and authenticate you, which you hope will never be stolen, is because of know your customer laws, so you can thank your government that pictures of your passport got stolen and for whatever criminals and rogue Coinbase employees do with that info.
There are very good reasons for KYC, the problem here is not the government regulation, it's once again private companies being sloppy with their customer's data because sloppy is cheap and it's not their info on the line, it's yours, so there's little motivation for them to safeguard it _unless_ they're compelled to do it by law.
This is costing Coinbase $400M. They are well incentivized to prevent this.
The people who designed a government regulation to deputize private companies couldn't possibly have known how sloppy private companies are with other people's data?
They could have designed KYC to minimize long-term storage requirements etc at some cost to what they could enforce, but a government like the US is inherently sloppy with the rights that are reserved for parties besides itself.

That's the same move from the Ransom movie from 1996 https://youtu.be/haThIxPnYro?si=Jxu0elA-ylB5Z15q
I’d say the better thing for customers would be to pay the ransom demand and get the PII back. If they want to fund a reward scheme too, well great, but if it were my data, I’d care more about Coinbase limiting the breach of the data, not playing around with retaliatory rewards.
There is no guarantee that an anonymous criminal is going to hold up their end of the agreement. Coinbase has no idea who they're negotiating with or where that data has been shared.
That, and they're reimbursing customers who were tricked.

> recruited a group of rogue overseas support agents
Why not just say what country the are from and how they hired them to start with. It's presented as those sneaky "overseas" people that somehow got access to our systems. This company makes what, a few billions in revenue but they couldn't vet and hire the right people?
I'm having de ja vu here. If they only found out when they attempted to extort them does it mean they don't even bother to log employee access? Is there any means for accountability at all internally?
It would be so simple to have access tracking and flag or lock out rogue employees... I look forward to seeing what the golden parachutes look like.
Looking at their blog post, it seems like they paid customer support agents to hand over sensitive data. The attackers did not have access to any agent accounts themselves, and the customer service agents were accessing data they were already privileged to anyways.
https://www.coinbase.com/blog/protecting-our-customers-stand...
The customer service agents were accessing data they were already privileged to anyways.
That's not how front line support agent access should work. You get access based on active cases you are working on, not the keys to the kingdom because you might need to support a member at some future point in time.
It makes me wonder what type of access support agents have in the first place. A lot of this information should require "unlocking" on a case-by-case basis by challenge/response while interacting with a customer.
I built the admin panel used by internal employees and contractors at a major fintech payments processor (PCI Level 1). We had to add multiple levels of safety once we decided to hire a team outside of our US office including logging, monitoring and also rate-limiting (ask for manager to approve if more than 5 full details requests, etc.) I think these requirements are much stringent due to PCI-DSS standards for credit card processors. I wonder if a lack of such standards in crypto makes the companies holding customer funds more lax.
Logging and retroactive auditing seems like the very least they should do. Even asking the customer service agent to first provide identifying details of the customer they can't easily know or guess by themselves doesn't seem excessive, given the sensitivity of the information.
It won't work for 100% of all calls (what if the customer is locked out themselves etc.), but those calls can then be handled by even more closely monitored agents.
"Less than 1% of monthly transacting customers" means up to 1% were accessed – that seems very high, i.e. much higher than the number of customer service contacts I'd expect.

So this is probably why the phishing calls have increased from ~1 per month to ~3 per week.. good to know... Wish coinbase would let me DO something about it... Maybe fresh accounts for everyone? Maybe KYC data not directly linked to accounts? There should be SOMETHING they can do because the sheer volume of people constantly harassing CB customers is nuts.
> So this is probably why the phishing calls have increased from ~1 per month to ~3 per week.
Yes and their timeline doesn't add up with what they disclosed. If you take the Coinbase narrative, they only believed this was a 'material' issue once contacted by the hackers for a $20m demand, they weren't able to put the pieces together themselves.
The phishing has been elevated for weeks, especially via text message, and their lack of internal controls for access and monitoring are clearly severely lacking.
When i get those calls, i usually tell them “why dont i just save everyones time and just give you my bank account number, password and social security number? That sound good?”
Forget relying on brokerages like COIN. If you care about the security of your digital assets, use a cold wallet or non-custodial account.
The comment you're replying to was complaining about scam calls, not about wallet security.
Using a hardware/"cold-ish" wallet does not protect you from scam calls: https://www.bleepingcomputer.com/news/security/physical-addr...
There should be an ISO standard with respect to how much power and information that front line customer support agents have. The more information you need, like changing passwords or accessing personal information, should get forwarded to higher level customer support agents with better training and more monitoring. This way you can design customer support experience with as little exposure to security issues as possible.
> better training and more monitoring.
That’s very load-bearing. It won’t help.
The CS reps are based in a LCOL country so the opportunity for theft is simply incredibly lucrative.
What is really needed, is customer-in-the-loop for access to their data. The problem is, not all accesses would make sense. Doing analytics over the data of the top 1% of customers, for example, requires some level of access, but would freak out those customers if they had to approve it.
If it would freak out the customers, maybe they shouldn’t be doing it.

They main defense against internal attacks is bookkeeping. Banks have been dealing with this for thousands of years. I recommend the corresponding chapter in Security Engineering by Ross Anderson: https://www.cl.cam.ac.uk/archive/rja14/Papers/SEv3-ch12.pdf
Compartmentalization is a very expensive customer support model.
So are $20M ransoms and the reputational damage from data breaches.
Maybe it’s a naive question, but in many breach reports I see things like 'No passwords, private keys, or funds were exposed.' How come companies can usually protect that kind of data, but not emails, names, and other personal info?
Companies want the ability to use things like emails, names, and other data for user experiences (go to settings, see name and change it), advertising (target this address book for X ad), etc. So these are typically plaintext (oversimplified) and accessible by different systems while passwords or private keys have one use case only and can have a higher bar of protection.
Such data is typically encrypted and purely write-only, only read by the system itself. Thus it is only exposed if the database itself is exposed. If the leak was compromise of the systems that access the data (which appears to be the case here--insiders copied data they could access) the write-only info is not exposed.
A properly implemented login system will never store a password in the first place. Properly hashed passwords can still be cracked in some cases, but if your password is strong and the hash is good, it’s safe.
It was some BI/analyst database that leaked?
The article says they sent an email, but I usually ignore emails from Coinbase. I hope there's going to be a better way to find out if your data was breached. I was locked out of my account before, and had to upload an ID. I thought they didn't store it... :o
It's ironic this came [out] the day after COIN is going to be added to the SP500.
And also the same day as it was reported the SEC is investigating Coinbase over claims it overstated user numbers in past filings (https://www.thestreet.com/crypto/policy/sec-is-investigating...).
It's been a bad day.
I’ve been getting scam texts from scammers who claimed my Coinbase account was compromised and to contact them. I wonder if this incident was the root cause
I'm surprised they only demanded $20M. Surely that customer data is potentially worth, like, potentially orders-of-magnitude more.
Correspondingly I'd assume either a) paying the ransom doesn't take it off the market or b) the info they stole isn't that interesting.
They only stole 80000 emails (1% of their monthly active users) not the whole userlist
> less than 1% of Coinbase monthly transacting users
Unclear if users whose data was stolen, but did NOT transact in the last month are included in this statistic. Feels like a very intentional phrasing on their part

I also like 'last 4 digits only' as if that's not the most important parts and the part so many places use to validate your identity, the first 5 are just area and group so they're not exactly random.
Everyone's social security number is available. If you go download the leak referring to in this HN post [1], your SSN is certainly in it. Mine was, everyone in my family's was, almost all of my friends' were.

A separate KYC department that verifies identity then immediately deletes the images?
When was the last time your passport was copied in Europe?

Hats off to the hackers for getting through to Coinbase support
Underappreciated comment.
The article keeps saying overseas employees or contractors, but isn't more specific on who Coinbase entrusted with this sensitive customer PII.
The bottom line is Coinbase didn't adequately secure sensitive customer information, and it was leaked.
Not, "Gosh, 'overseas' people, what can ya do?"
How can customer support operate without knowing anything about the customer?
You know how your bank asks you to verify details when you call?
Without the right details the customer support people don’t get entry into the customers account details.
Banks have been doing this for 30+ years..

> Coinbase didn't adequately secure sensitive customer information, and it was leaked
Practically every company has someone with credentials who is in some combination of debt, a damningly-adulterous relationship, a damningly-illegal substance relationship and/or feels underappreciated or slighted compensationwise. The question is generally how much it costs.
Which is exactly why insider threats should be explored as a threat-model and mitigated to make the blast radius as small as possible via rate PII sanitization, access controls, access monitoring, rate limiting, etc.
Question that needs to be answered if they were prosecuted. Losing your job but getting to keep the bribe just means it will still happen.
They are probably used as scapegoats and didn't even leak the stuff. Crypto companies tend to do that.
Bribes are one thing, but threats could also happen. This is a big part of the reason why I absolutely hate entities that think residential addresses should be public record.
This is a precedent to Coinbase employees getting physical threats at their door just because e.g. some voter registration, utility company, bank, credit card, or court record decided to release their name and addresses on the internet. People could show up at some Coinbase software engineers' apartment doors with guns demanding they send BTC to arbitrary addresses.
AFAICT it's impractical to keep residential addresses 100% private/secure - too many ways to get an address from any number of companies, organizations and governments that collect it for various reasons.
Plus numerous ways to infer your address from other data sources, including apps that grab GPS on friends' cellphones when they visit, etc.
Finally, shutting down paid data brokers seems virtually impossible in practice, which means anybody googling you can pay $20 and get everything.
Remember, the issue isn't lazy goodguys but even slightly motivated badguys, who then use third party scripts to do the data collection.

Saved dimes on customer support, lost $400m.
It's hard to not believe in Karma sometimes.
It will happen (at least attempted) with on-shore support staff too, My next door neighbour used to work for a UK high street bank and even there support staff were approached, with some of them first befriended, and eventually bribed in to passing along PII. No doubt it happens in the US too. Just costs the bad guys more.
Oops, I was wrong:
From https://techcrunch.com/2025/05/15/coinbase-says-customers-pe...
> The company said the hacker stole customer names, postal and email addresses, phone numbers, and the last four-digits of users’ Social Security numbers. The hacker also took masked bank account numbers and some banking identifiers, as well as customers’ government-issued identity documents, such as driver’s licenses and passports. The stolen data also includes account balance data and transaction histories.

Nobody has sole control of their cryptocurrency by definition. It's a consensus protocol. (On a practical level, there are always layers of trust.)

... and once the crypto is transferred. Poof, you're ducked.
I mean... wasn't coinbase sort of scammy to begin with? Several years ago I gave them some USD, turned it into BTC, saw the value of the BTC go up, but when I tried to cash out was told that wasn't a thing that was supported by their platform. Later I was told I could apply for a $399/year credit card and could partially pay off the balance with BTC sale proceeds. I'm sure this was all disclosed somewhere in the terms of service I clicked through, and I only lost $1000 to their scheme.
But I've always wondered why people think this is how investment vehicles work. I monkeyed around with stock market bets and even Robin Hood allows you to cash out of your positions.
Coinbase most certainly permits cashing out.
Are you sure you didn't fall for a scam version?
I dunno why you had problems, but I've been using Coinbase with no problems at all for years. It's linked to my bank account, so if I want to pay for something with bitcoin, I can easily buy and send bitcoin with just a few clicks. I don't invest or speculate in bitcoin, so I only maintain a small account balance. And selling bitcoin and transferring the proceeds to my bank account has been just as easy and trouble-free.
It's more likely you didn't "lose" $1k, but that you had "missed profits". And if you missed the profits because you didn't verify yourself earlier for withdrawal, then that's on you.
Coinbase supported direct bank withdrawals well before they launched their crypto debit cards.
Your profits are your profits. Coinbase can hold them until you verify yourself for withdrawals, but they can't just take them.

It's really unfortunate that KYC regulations required Coinbase to have this information in the first place. We should be establishing strong social norms against sharing PII without a legitimate reason; this is not just an individual theft risk but a national security risk. Coinbase doesn't pay into your Social Security account, so they shouldn't have your Social Security number. They don't visit your house, so they shouldn't have your address. Etc.
Historically, although KYC regulations were widespread in Communist countries, they were unthinkable in most democratic countries until 9/11, which provided spy agencies with their golden chance to write their wishlist into law. But unfortunately that helps foreign spy agencies just as much as, maybe more than, it helps domestic ones.
In https://en.wikipedia.org/wiki/Know_your_customer#Laws_by_cou... you can see when they were introduced in different countries.
Let's hear you repeat this position after your Coinbase account is compromised and you're looking for recourse.
You seem to believe that AML/KYC regulation exists to benefit customers or to prevent or recover from account compromises. It does not, and I have no idea why you would think it does. Something like a Yubikey or iris-scanning stations could help to prevent Coinbase account compromises, but AML/KYC regulations do not require or even encourage them, though perhaps someday they will.

Employees at Signal must be getting bribes as well, or even threats of violence since they can get nation state Secret communications these days.
Got to make it so employees can’t do anything nefarious. This helps protect them.
How would employees of Signal access the encrypted messages?
Employees can't get access to encrypted messages.
But they can look the other way about flaws in their Electron client.

They don’t need to.
Under specific conditions, the client can communicate with malware already on device, save data locally for other software to pick up, or downright stream the decrypted software to a third party.
Most likely is to introduce a flaw in the client that can be used by other walware on the client.
Clearly no red team members on HN these days.

Roll out an update that defeats the end to end encryption in some subtle way that wouldn't go noticed for a few days. They'd be told when to do it for maximum effect, and if the window is small enough it might even go unnoticed for far longer when another uncompromised update overwrites it. They have no duty to report such things to relevant authorities even if it was discovered internally, so you could be looking at some corporate coverup that while not in on it, seeks to minimize liability/embarrassment.
Really, can you possibly tell if your Signal messages were compromised? Now that iPhones aren't really jailbreakable, you can't even see inside your own device.
