CrowdStrike effectively bricked windows, Mac and Linux today.

Windows machines won’t boot, and Mac and Linux work is abandoned because all their users are on twitter making memes.

Incredible work.

Not saying Windows isn't trash, but considering what CrowdStrike's software is, they could have bricked Mac or Linux just as hard. The CrowdStrike agent has pretty broad access to modify and block execution of system files. Nuke a few of the wrong files, and any OS is going to grind to a halt.

    Probably would have been worse if this was on Linux. That's like 90% of the internet.

    Good thing is the kind of people making decisions based on buzzword-bongo filled PR campaigns like Crowdstrike's are already forcing their IT to use Windows anyway.

    It was a serious ask to install it from auditors that don't know what the fuck they are doing. On all ec2 machines for "reasons" I'm sure there are companies out there pushed into doing this because they don't have people willing to die on those hills.

    Yes and no. Linux is inherently more diverse. All the different distros doing things in different ways, sometimes with different components. It's not as much of a monoculture as Windows. There isn't a Linux that 90% is.

    That's... Not great. I didn't actually think about what all these wild AV systems could do, but that's incredibly broad access.

    Maybe I'm just old, but it always strikes me as odd that you'd spend so much money on that much intrusive power that on a good day slows your machines down and on a bad day this happens.

    I get that Users are stupid. But maybe you shouldn't let users install anything. And maybe your machines shouldn't have access to things that can give them malware. Some times, you don't need everything connected to a network.

    I didn’t actually think about what all these wild AV systems could do, but that’s incredibly broad access.

    Always has been. I've clean Symantec A/V off way too many systems in my time, post BSOD. That crap came pre-loaded on so many systems, and then borked them. The problem is, that in order to actually protect system from malware, the A/V has to have full, kernel level access. So, when it goes sideways, it usually takes the system down. I've seen BSODs caused by just about every vendor's A/V or EDR product. Shit happens. Everyone makes mistakes, but when that mistake is in A/V or EDR, it usually means a BSOD.

    It's tough. The Internet and access to networks provides some pretty good advantages to users. But, it also means users making mistakes and executing malware. And much of the malware now is targeted at user level access; so, you can't even prevent malware by denying local admin/root. Ransomware and infostealers don't need it. A/V ends up being a bit of a backstop to some of that. Sure, it mostly is a waste of resources and can break stuff when things go bad. But, it can also catch ransomware or alert network defenders to infostealers. And either of those can result in a really, really bad day. A ransomed network is a nightmare. And credentials being stolen and not known about can lead to all kinds of bad stuff. If A/V catches or alerts you to just one or two of those events and lets you take action early, it may pay for itself (even with this sort of FUBAR situation) several times over.
