I am generally in favor of security improvements, but I do not really see much of a benefit here. This attack vector requires both that the user enabled developer settings and that they have remote adb enabled. So, this does not seem to be a realistic attack vector for 99.9% of the users and most of the other 0.1% probably know what they are doing.
The other proposed change (to restrict access to certain interfaces or IP addresses) seems good, but why not allow developers to restrict access localhost?
It reeks of trying to block Shizuku, Canta, etc. using a way that only makes it look like a side-effect.
"Security" is just a scourge on software at this point. It means 2FA on every trivial site, being logged out every few hours for no good reason, having to fuck with settings and type "disable sandbox" to run an agent in YOLO mode which still won't work over mobile, being unable to install an unsigned extension at all in firefox (not behind a setting, literally impossible - you have to get Firefox Developer Edition), sites spamming me to get passkeys which will no doubt be declared insecure and replaced by some more moronic thing when users find a way to get hacked with those too, 80 layers of access control/service identities/IAM/Oauth to host an S3 bucket, OAuth everywhere that won't even work on a headless device, banking websites that want their own special snowflake app as 2FA instead of using TOTP, banning VPNs and slowly rolling out completely real identity surveillance on every corner of the internet to "protect the children", ban open-weight models because the numbers are going to send your data to China, and it just goes on and on and on..
When is this insanity going to stop? I really think the IT security industry ought to be ashamed of itself. Security has become a totalizing value that trumps every other value - convenience, user-friendliness, privacy, hackability, openness, just anything at all in the name of MORE SECURITY.
There is a simple and highly accurate heuristic to tell if a security measure is reasonable:
Is it an open standard that anyone can permissionlessly implement?
When the answer is yes, there is a high probability that it's something reasonable, e.g. TOTP.
When the answer is no, what you will find behind the curtain is either a fool or a crook.
This heuristic is not covering the dimensions of interest here, because it fails to address the key security questions (that the industry usually wants people to not even think about):
Who is doing the securing, whose interests are being secured, and against who/what?
Security isn't an unqualified good thing to have. It's just an instrument of control. Who wields it and how are the paramount questions. You can have an "open standard that anyone can permissionlessly implement", aimed at protecting interest of third parties, by securing the device from its actual owner. In fact, that describes many, if not most, security measures introduced in computing over the past 20 years, especially on the web and mobile devices.
Don't forget "Remember for 30 days" checkboxes that don't do anything.
IT has always been a spectrum with security at one end and convenience at the other. There is no recent trend that’s changed that. That’s just how life works.
Right, but security maximalist are running the asylum now, and they try to sell everyone the lie that more security is possible.
Also, the original sin: framing it as "security" vs. "convenience". It's not. The other end of the spectrum is utility - as in, maximally secure computing device is an inert rock. More security means less utility - reduced functionality, constrained capability, reasonable use cases no longer possible. It means manual process where previously automation or batching was possible. It means more electricity, more compute, more money spent.
It means more user time and therefore more human lives wasted.
This ultimate non-renewable resource is what we're trading off when we accept even more security. This trade-off needs to be respected much more than it is.
"Better things aren't possible" is a terrible outlook. There have been real improvements in this space, such as passkeys, and recognition that some of this stuff, like frequent password changes, is counterproductive.
> 2FA on every trivial site
But it helps against account sharing, err I mean they make database leaks irrelevant except for private info of the customer, err I mean that we can now send more mail to the customer about new AI features without risking they think it is phishing, err I mean this is the easiest measure for the auditor findings so since we implemented this we don't need to fix all the crappy internal api auth problems and atrocious out of date dependencies, err I mean...
> But it helps against account sharing
This is actually a feature, very common in real world, that security maximalists keep insisting is a bug.
I really think the IT security industry ought to be ashamed of itself.
See Pournelle's Iron Law of Bureaucracy.
It is all so frustrating.
Reminds me of what Ubiquiti tried to pull a few weeks ago. They wanted to force everyone to their Cloud UI and login instead of the local interfaces so they reduced the local session lifetime to something insane like 20 minutes while lying to our faces and saying it is for security, and kept the session lifetime longer on their cloud panels. They made sure to exclude this from their changelog too.
The community started monkey patching their local scripts, wrote services to undo their changes, many people disabled auto-updates as Ubiquiti only makes their product worse with their updates. Publicly complained on their support forum that we are onto their little plot.
They ended up backtracking for now but you just know they will try again like Google does.
> This attack vector requires both that the user enabled developer settings and that they have remote adb enabled.
Not just that. A non-development Android build will also prompt the user when a connection is made to authorize the client's key.
This once again isn't about security of users, this is about security of the company's interests.
Google just got hit by yet another record antitrust fine by the EU [1]. But as long as they see these fines as cost of doing business, nothing will change. Especially if it always takes almost a decade to push this through the judicial system. Their net income last year alone was $130 Billion.

Eh, that is if they pay. Trump already made threats for tariffs in regards to those fines.

In the post iPhone era, a lot of what gets sold as security features is actually just removing functionality from the device.
In early days of this, I honestly think it was rooted in the famous Steve Jobs paranoia, the one that shipped without an app store and told users to use Safari, the same Steve Jobs that was said to not want certain medical devices during cancer treatment to touch him because they weren't beautifully designed. It was fundamentally about not wanting "dirty" things coming in contact with his "perfect" device. They dressed it up in language about security as a post hoc justification.
I remember in those days people would say they didn't want it to be like malware ridden Windows 98. But they omitted the weak security behind Windows at that time, which modern systems had long ago exceeded, even in the Windows world.
It's a security theater but you should at least respect that the guy was willing to die for beautifully designed devices and rid us of Adobe Flash.
> you should at least respect that the guy was willing to die for beautifully designed devices
I don’t think that kind of stupidity warrants respect.
This. I'm a developer, I've published Android apps, & I've still managed to lose access to a device that had dev settings enabled purely because remote adb enablement is a (extremely fiddly) toggle that happened to be off on the device at the time the screen broke. Having these two enabled simultaneously is such a rare case in the wild as to be entirely negligible as a vector.
Sometimes attacks happen from users being instructed to enable settings in order to achieve something regardless of whether you’d expect them to have a reason to use the setting
Sure, sometimes people get social engineered into taking money from their bank account and giving it to criminals. Should banks stop allowing withdrawals?

If someone is willing to click on build version 5 times and then gets a mystery prompt about dev mode, and still goes along with the next 4 steps I think they were gonna get hacked a billion different other ways
The solution to social engineering can't be to remove useful features - you can socially engineer people to do literally anything, you can have someone walk to their bank, withdraw cash & fly to you with it with a dating scam: there are literally no boundaries once you get into that area of security. Digitally, you combat that through UX, messaging & education.

Then maybe the best course of action is Google adding a warning before enabling certain settings that help normies avoid these attacks.
Along the lines of "Are you being asked to do this by someone else? Be cautious, as your device could become compromised."

"In a normal scenario, a bad actor cannot gain an ADB connection."
It depends on how you define a bad actor.
"rootless privacy tools based on Shizuku."
It's not for the security of the owner; it is for the security of the government.
Trusted execution environment applications like the EU Digital (Identity) Wallet, or whatever they will demand next to protect the children, heavily rely on the fact that users cannot mess with their devices or install unsanctioned software. We all know how badly the Intel SGX story is going.
> why not allow developers to restrict access localhost?
Ads and tracking, obviously (https://localmess.github.io/)
All these changes Google is doing to Android aren't for you as the user, they are to protect their business interests from the user.
It seems to me a lot of Google lately is to block things they don't like using ways that only look like side effects.
The introduction of Manifest V3 API in Chrome for extensions, and disabling Manifest V2 for security reasons. It just so happened that ad blockers were made incompatible with the Manifest V3 API. It's a little blatant considering this came right around the time that YouTube began showing warning messages to users with ad blockers...
Requiring developers to verify their apps via Google Play Developer Console and blocking any unverified APK installations. This is done in such a way that it just so happens to squash F-Droid and most FOSS apps for most people, and blocks any serious competition to Google Play or any apps they don't like.
Of course, there's all this talk about preventing malware, but it is a fact that if you download any random ringtone or PDF app on Google Play it's going to come with probably 25 trackers and send your data to every jurisdiction in the world, and many apps even fail to declare any of this via Google Play data safety or privacy policy. Let's not forget that spyware is a form of malware. Take a look at the leaderboard :) https://reports.exodus-privacy.eu.org/en/reports/list/?filte...
In my opinion, this would probably be an indication that maybe Google controls too much technology and that they may need to be broken up to ensure fair competition. For Christ's sake they almost broke up Microsoft not that long ago for shipping a browser with their operating system, and now Google is blatantly controlling the operating system, the platform and app store, the ecosystem, the browser, the ad network, and abusing their power over it however they can.
I still can’t believe that an advertising company was able to effectively neuter ad/content blocking for 80% of the world under the guise of wholly invented safety issues.
They wouldn't have been able to if people didn't use a browser created by an advertising company.
Isn't this because of the kimwolf (and now 6+ other botnets) that are taking advantage of people running residential proxyware unknowingly on the device which permits outbound connections to 127.0.0.1 on tcp/5555 to auth in and exec wgets or drops a loader that grabs the ddos malware APKs and install it?
It seems to require the user to:
1. Enable Developer Mode by going to an obscure settings page and tapping the build number seven times
2. Enable USB ADB debugging in the Developer Options
3. Establish an actual USB ADB session
4. Enable TCP/IP ADB debugging in the Developer Options
5. Unknowingly download a malware app from the official Play Store
6. Blindly click "Yes" on the permission prompt.
In other words: this is all but impossible to impact regular users, and it requires a particularly careless developer to be hit by it. And it only works if the Play Store is useless at preventing malware in the first place - but I thought their excellent app scanning was the entire reasoning behind all-but-banning 3rd-party app stores and sideloading???
It is "for safety" in the same sense that governments banning all encryption is to "protect the children" or to "prevent terrorism": flawed justification invented to distract from the real reason they want it.
I think expert users on HN seriously downplay the ability and willingness of "regular users" to do very stupid things on their devices. If grandma wants that app that gives her a beautiful horse as a lock screen image, she will follow every one of those six steps that the malware HorseLockScreen app developer presents to her. She will tap a button that has a skull and crossbones icon, that says "tapping this will drain your bank account and kill your dog" if she thinks it will let her do whatever she's trying to do on her device. Have you guys never done IT tech support for your elderly parents' computers?
I'm not saying it's right to respond by simply locking everything down, but let's not downplay the blast radius of basically every attack that involves telling the user to do things.

Have you ever worked with someone who barely knows how to use a mobile phone? They will hand their phone over to someone they barely even know to do something they don't understand. They will follow instructions from a stranger over the phone, without understanding what the phone is warning them about.
I have worked with such a person. They did have someone walk them through a dubious process. Thankfully they realized what was going on before the process was complete, but who knows how much damage was done by the initial steps.
There are legitimate security reasons here. Whether there are reasons beyond that is an open question.

You haven't been able to connect to an android device on port 5555 for yeeears. Every time you enable adb/IP it generates a new random port, or you need to use the QR/PIN pairing thing. On top of needing to enable developer options, adb/IP, confirm the fingerprint.
Millions of Superboxes and various digital picture frames say different.

Hadn't thought about that additional attack vector those proxies are enabling. In addition to "internet access from residental connection" privileges, the attacker also gets access to loopback on the device that does the proxying...
But even then, shouldn't this show the same permission prompt for the user that anything else trying to connect to port 5555 would?
Yes, but users are told to allow it if they want to get free coins etc.

From memory, for the kimwolf exploit things, other user already had good points about the device already beeing compromised. But also, the authentification part of ADB was just completly disabled, which is why this worked. Basically it was so-compromised as-is that ADB was just sitting here open, as is you where to put SSH with no authentification at all.
There are so many people in my neighborhood here that are actively members of residential proxy networks that it makes me stabby. They don't seem to care.
That said, I wasn't under the impression kimwolf was that technically sophisticated. Some of the others are, though.
It's not because of security. It's to slowly close any avenues for side-loading stuff
It's not side loading. Word you are looking for is called "installing".
The bug literally describes how they're avoiding OS security restictions by going through the debug port.
This is a CVE by any definition and you'd be screaming your head off if any other OS would allow this kind of permission bypass (or even if another app did it).
But sure, Google evil.
There's a vulnerability in my bike - when I push my left handlebar hard forward when riding down a road, I can crash into a pillar.
I think a possibility of knowingly pushing the handlebar should be removed from me, just in case. After all I could do it.
And while we're at it I just realised my car has a similar vulnerability, but triggered by a slightly different mechanism, but the effect is exactly the same, I can crash into a pillar.
Edit: oops, I just discovered that if I have a banking app installed on my phone, then tap my screen in the specific places, enter several numbers, including the number I receive in text, suddenly I lose all the money.
That's staggering!
I mean, you made a good metaphorical case for controlled handlebar slop/headset resistance in bicycles/motorcycles. Which are things that exist to mitigate crashes from oversteering on both of those vehicles!

You, and may of the people in the thread here are at cross purposes, I think.
The CVE mentioned in the article is https://nvd.nist.gov/vuln/detail/CVE-2026-0073. That's a real CVE: logic error leading to auth bypass. Fix can be seen at https://android.googlesource.com/platform/packages/modules/a....
Separately, a number of people here are attempting to argue that the availability of On-Device ADB should be regarded as a "CVE" in and of itself. Google does not appear to share that view.

Or perhaps they wouldn't? CVEs aren't holy scripture, and "security" isn't the most important consideration in computing. This theatre has gone too far IMO.
Allowing strangers to run adb commands on your phone without your consent is about as bad as a compromise can get. Your keyboard can be replaced with a keylogger and all of your data can be stolen without your knowledge by simply connecting to the wrong wifi network.

Depends how you define a CVE. If owning and controlling your device is a CVE/bug then sure you need a tight box with anti tempering as well.
Can you provide a reasonable definition where an authentication bypass in ADB doesn't qualify as a vulnerability? Is there a use case for allowing anyone on your network to run adb commands without your approval?
There are 3 things which I feel like are being confused here:
1. There was a genuine authentication bypass vulnerability in ADB (bad)
2. Initial proposed change wants to add an option to limit the ADB server to certain IPs or network interfaces (good - it doesn't affect you)
3. Response to the original request, proposing that ADB shouldn't be allowed to listen on loopback interfaces (bad/nefarious - it breaks functionality)

"An app can bypass OS security system with certain setting enabled" absolutely fits into CVEs. There's no "depends: on it.
I love how quickly you all forget about security and privacy when it gives a chance to angrily rant.

The original issue is proposing letting the user assign the debug service to a specific interface, one of which would presumably be loopback. This article is about the proposal from a developer that it should only ever be assigned to wlan0, which would break a lot of apps.
Letting applications bypass permissions with this feature is the exact usecase they don't want to lose. If anything, I don't see them being against the original proposal possibly restricting non-loopback access, which would enhance security.
It would break exactly 0 apps because none of the apps should be using this API to access your private data and phone call audio.

Because you know, the actual solution would be to have more granularity in authentication process than "allow whole device to attach to ADB", but that would be like, difficult... so they're not going to so that.
Right now any app on my PC connected to ADB could manipulate my phone then, and that's somehow not a CVE?
Is it a CVE that an app running on my PC could actually be running under GDB? It's the entire purpose of these tools.
In this case, the OS security restrictions should be questioned in the first place as excessive if a "backdoor" is necessary for normal function.
I am not sure I follow. Are you referring to the original CVE (?), I fully agree that it should be fixed, and it is not what my comment was about.
If you are talking about allowing listening on localhost - remote ADB requires enabling in the developer settings. It is a developer feature, similar to ADB over USB. If I'm charitable, it is possible that they are seeing too many people that are using Shizuku without understanding the security implications. But Shizuku has a lot of useful applications and they use ADB because the Android APIs and permission system are lacking and do not make these applications possible.
New CVE found in Bank of America app that may cause user to transfer money to hackers if they press certain combination of keys.
Actually that's what the whole fraud detection thing is about. If you transfer money wrong, they lock your account. Some countries like Sweden even went cashless so they can see all transfers.
More like if you have some settings enabled someone on your network can do it for you without your permission

"...avoiding OS security restictions by going through the debug port..." the user delibretry opened and paired to app with clear visual confirmation in order to use it.
Even if you have to deliberately enable a setting and enter a pairing code?
It's like saying that the fact the user knows their own password is a vulnerability because they might enter it to log into their account.
no, its a cve if the app can just do it automatically, it is NOT a cve that user goes through 5 steps that they very explicitly do, including unlocking hidden menus to open up developer options, and then allow it.
seriously, get real, please explain how your train of thought works here
