some comments purportedly (i did not verify) from one of the maintainers:

>Dear All, I'm Sam and in I'm working with Franck on CPU-Z (I'm doing the validator). Franck is unfortunately OOO for a couple weeks. I'm just out of bed after worked on Memtest86+ for most the night, so I'm doing my best to check everything. As very first checks, the file on our server looks fine (https://www.virustotal.com/gui/file/6c8faba4768754c3364e7c40...) and the server doesn't seems compromised. I'm investigating further... If anyone can tell me the exact link to the page where the malware was downloaded, that would help a lot

>Thank you. I found the biggest breach, restored the links and put everything in read-only until more investigation is done. Seems they waited Franck was off and I get to bad after working on Memtest86+ yesterday :-/

>The links have been compromised for a bit more than 6 hours between 09/04 and 10/04 GMT :-/

so, it appears that the cpuid website was compromised, with links leading to fake installers.

For what it's worth - I used to write CPU reviews a while back - I can vouch for both Sam and Franck. Franck is the guy behind CPUID and Sam is a close friend of his, who was known for working at Canard PC on top of his work on Memtest : https://x86.fr/about-me/

  • that is pretty cool!

    when i say i didnt verify, i just mean that i ripped these quotes out of reddit, and did not check whether the reddit username that posted the comments is known to be an identity of Sam.

    • I didn't talk to him to verify, but at the very least it's his username (and the account is old enough at this point : https://www.reddit.com/user/Doc_TB/comments/), and his very Belgian english.

      I know both are close and Sam handles his website, so since the links are fixed, I have near zero doubt it's Sam here on reddit.

Glad that they figured out the issue and fixed the links. When I first read this, I assumed it was actually the sketchy ads that are run on www.cpuid.com.

These are the real ads I just saw on a single download page for CPU-Z: "Continue to Download", "Install For windows 10, 11 32/64 bit Get Fast!", "Download", "Download now from PC APP STORE", or "Download Now For windows 10, 11 32/64 bit". Many of them appeared multiple times on the page.

The real download links don't even say they are download links.

I love the winget CLI in this situation. This is all you need: `winget install CPUID.CPU-Z`.

  • Personally I'm fine with the scammy ads. I feel most people who would use CPU-Z are pretty technical and should be able to tell the difference between an ad download button vs the real one.

    That, and you should already be using an ad blocker.

It's the third time that I've read something about availability notifications on discord and other chats getting abused for timed attacks in the last few weeks.

  • After my Wordpress site got hacked way back through an exploit in one of the WP files, I set up a cron job that compared the hash of the static files with expected hash, and would fire off an email if they differed.

    The script lived above the web root, so they'd have to escape that to tamper with it, and was generated by another script.

    Saved me a couple of times since, well worth the 15 minutes I spent on setting it up.

  • Can you share what those other attacks were? It's helpful to study additional attacks to know what to look for.

Any idea how the compromise was achieved?

  • i have no clue. i yoinked these quotes from the reddit thread where sam replied.

    i am sure that we will see a write-up once the investigation concludes. it hasnt even been a day yet though, so i imagine sam is still in damage-control mode rather than root cause analysis mode.
