Someone negrate me or whatever if I'm wrong or if someone explained this during the superchats (I didn't get to finish the stream yet), but I'm pretty sure Null (and the majority of the media) got the Crowdstrike story wrong.
Crowdstrike is basically just advanced antivirus. It does more invasive stuff than antivirus normally does by essentially rootkiting the computer it's installed on. It's better than other antivirus (supposedly) because it doesn't just use signatures for known viruses, it watches all the processes on the machine for malicious behavior. For example, you can write a bespoke crypto virus and replace cmd.exe with it on a machine protected by crowdstrike, and when it runs it'll still catch it when it sees cmd.exe try to encrypt all your files. Most antiviruses aren't going to stop cmd.exe, and most antiviruses need to have a copy of the virus to be able to detect it, crowdstrike doesn't. Supposedly it uses AI or something.
Crowdstrike does not replace or suppliment any update mechanisms on the machine, or if it does it's a secondary function. The fuck up with crowdstrike was a bad crowdstrike update, not a bad OS update pushed by crowdstrike. For most software, the worst it could do is fuck up the software, but since crowdstrike needs kernel level access to do all the stuff it does, the update broke Windows.
Crowdstrike is also available for Linux to protect servers in basically the same way, and they had a very similar fuckup with Linux not that long ago. It's just significantly less popular on Linux than on Windows because Linux doesn't really require an antivirus the way that Windows does. The vast majority of Linux installs are servers limited to an SSH port and a port for whatever service they're running, and mostly exist in isolated, firewalled networks in a datacenter/cloud with no other local devices, whereas Windows runs on most peoples desktops, most buisnesses' AD servers (which need to be accessible to all the desktops in the company), POS devices connected to the same network as all the desktops, etc., therefore the vast majority of Windows machines (including servers) need an antivirus whereas the vast majority of Linux boxes don't.
Most of the media is calling this a Microsoft problem, but it's really not. It's just a Crowdstrike problem that happens to only affect Microsoft machines this time.
Also, Crowdstrike glows very bright. They're the company the DNC hired to blame the leaks on Russia with no evidence. I doubt that's relevant to what happened with the botched update, but it's worth mentioning.
