Technology

Linux and Mac just got free advertisment.

Annoyingly, my laptop seems to be working perfectly.

AWS No!!!

Oh wait it's not them for once.

One possible fix is to delete a particular file while booting in safe mode. But then they'll need to fix each system manually. My company encrypts the disks as well so it's going to be a even bigger pain (for them). I'm just happy my weekend started early.

CrowdStrike Holdings, Inc. is an American cybersecurity technology company based in Austin, Texas.

Never trust a texan

Huh. I guess this explains why the monitor outside of my flight gate tonight started BSoD looping. And may also explain why my flight was delayed by an additional hour and a half...

oh joy. can’t wait to have to fix this for all of our clients today…

Stop running production services on M$. There is a better backend OS.

My company used to use something else but after getting hacked switched to crowdstrike and now this. Hilarious clownery going on. Fingers crossed I'll be working from home for a few days before anything is fixed.

This is a better article. It's a CrowdStrike issue with an update (security software)

I see a lot of hate ITT on kernel-level EDRs, which I wouldn't say they deserve. Sure, for your own use, an AV is sufficient and you don't need an EDR, but they make a world of difference. I work in cybersecurity doing Red Teamings, so my job is mostly about bypassing such solutions and making malware/actions within the network that avoids being detected by it as much as possible, and ever since EDRs started getting popular, my job got several leagues harder.

The advantage of EDRs in comparison to AVs is that they can catch 0-days. AV will just look for signatures, a known pieces or snippets of malware code. EDR, on the other hand, looks for sequences of actions a process does, by scanning memory, logs and hooking syscalls. So, if for example you would make an entirely custom program that allocates memory as Read-Write-Execute, then load a crypto dll, unencrypt something into such memory, and then call a thread spawn syscall to spawn a thread on another process that runs it, and EDR would correlate such actions and get suspicious, while for regular AV, the code would probably look ok. Some EDRs even watch network packets and can catch suspicious communication, such as port scanning, large data extraction, or C2 communication.

Sure, in an ideal world, you would have users that never run malware, and network that is impenetrable. But you still get at avarage few % of people running random binaries that came from phishing attempts, or around 50% people that fall for vishing attacks in your company. Having an EDR increases your chances to avoid such attack almost exponentionally, and I would say that the advantage it gives to EDRs that they are kernel-level is well worth it.

I'm not defending CrowdStrike, they did mess up to the point where I bet that the amount of damages they caused worldwide is nowhere near the amount damages all cyberattacks they prevented would cause in total. But hating on kernel-level EDRs in general isn't warranted here.

Kernel-level anti-cheat, on the other hand, can go burn in hell, and I hope that something similar will eventually happen with one of them. Fuck kernel level anti-cheats.

I was quite surprised when I heard the news. I had been working for hours on my PC without any issues. It pays off not to use Windows.

No one bother to test before deploying to all machines? Nice move.
