This works great for stationary pcs and local servers, does nothing for public internet connected laptops in hands of users.
The only fix here is staggered and tested updates, and apparently this update bypassed even deffered update settings that crowdstrike themselves put into their software.
The only winning move here was to not use crowdstrike.
Almost all computers can be set to PXE boot, but work laptops usually even have more advanced remote management capabilities. You ask the employee to reboot the laptop and presto!
I wonder how you're supposed to get PXE boot to work securely over the internet. And how that helps when affected disk is still encrypted and needs unusual intervention to fix, including admin access to system files.
I've been doing this for a while, and I like creative solutions, so I wonder about those issues a lot. Not much comes to my mind besides let's recall all the laptops and do it one by one.
From a home user? Probably ain’t shit-all you can do with PXE booting. But if you have a field office or somewhere a user can go with a hardware vpn appliance? Well now you’re in business.
