So why is this considered a crowdstrike issue and not a Microsoft fuckup?

Tartas1995 ,

Basically, crowdstrike wrote bad code that run as a driver, windows doesn’t like bad code in their drivers. Kernel level code is generally expected to run properly. crowdstrike’s kernel level code was really bad. Embarrassingly bad.

If the host creates a playlist and everyone can add their favorite song to the playlist, the host won’t be blamed if you add “erika”. People rightfully think you are an ignorant weirdo or a bad person, not the host.

OTOH, if you build a playlist manager for playlists everyone can add to, you make sure nothing anyone adds will break it…

Except that the playlists are super complex and there is no way to make sure. Like building an engine and having to make sure that no 3rd party accessory will break it. Like the parented “sand injector”.

Well do you want to have Microsoft approving EVERY driver for windows? Rip 3rd party open source drivers for retro hardware

You: why would Microsoft stab themselves?

Crowdstrike released bad code into prod without giving it some hours of testing in local machines or whatever. Incredible fuckup, inimaginable. But, let’s not take blame out of Microsoft, if a driver is faulty the system should be resilient enough no to crap the bed on login. At least enough for IT to be able to remotely access the system and fix it. The manual work the IT world has had to do because it’s lost remote access to workstations is insane.

To be fair, kernel level access by third party software is kind of frowned upon in the Linux world. Ask any desktop Linux user how they feel about NVIDIA (the only third party kernel code an average Linux user will install) and their drivers randomly causing strange issues on their systems up to and including kernel panics compared to the experience on AMD where the driver is open and built into the kernel itself. For security software that needs low level visibility, there is eBPF, direct kernel level access isn’t needed (though I believe CrowdStrike uses it, and thay actually did CrowdStrike Debian and Rocky Linux systems some time back).

MacOS blocked the majority of kernel extensions a few years ago as well.

Windows is the only OS where it has been designed in a way where kernel level access is the rule rather than the exception. So design flaws are at least partially at fault here.

Same thing would happen on Linux if someone wrote a bad kernel module and integrated it into the OS. In fact, Crowdstrike did have a similar problem a few months ago on Linux.

I’m no fan of Microsoft, but this isn’t their fault.
