All our servers and company laptops went down at pretty much the same time. Laptops have been bootlooping to blue screen of death. It's all very exciting, personally, as someone not responsible for fixing it.

Apparently caused by a bad CrowdStrike update.

Edit: now being told we (who almost all generally work from home) need to come into the office Monday as they can only apply the fix in-person. We'll see if that changes over the weekend...

Here's the fix: (or rather workaround, released by CrowdStrike) 1)Boot to safe mode/recovery 2)Go to C:\Windows\System32\drivers\CrowdStrike 3)Delete the file matching "C-00000291*.sys" 4)Boot the system normally

It's disappointing that the fix is so easy to perform and yet it'll almost certainly keep a lot of infrastructure down for hours because a majority of people seem too scared to try to fix anything on their own machine (or aren't trusted to so they can't even if they know how)

[–] HaleHirsute@infosec.pub 67 points 4 months ago (4 children)

They also gotta get the fix through a trusted channel and not randomly on the internet. (No offense to the person that gave the info, it’s maybe correct but you never know)

Yeah, and it's unknown if CS is active after the workaround or not (source: hackernews commentator)

[–] letsgo@lemm.ee 8 points 4 months ago

True, but knowing what the fix might be means you can Google it and see what comes back. It was on StackOverflow for example, but at the time of this comment has been taken offline for moderation - whatever that means.

Meh. Even if it bricked crowdstrike instead of helping, you can just restore the file you deleted. A file in that folder can't brick a windows system.

Yeah and a lot of corpo VPNs are gonna be down from this too.
