Please, enlighten me how you'd remotely service a few thousand Bitlocker-locked machines, that won't boot far enough to get an internet connection, with non-tech-savvy users behind them. Pray tell what common "basic hygiene" practices would've helped, especially with Crowdstrike reportedly ignoring and bypassing the rollout policies set by their customers.
Not saying the rest of your post is wrong, but this stood out as easily glossed over.
A decade ago I worked for a regional chain of gyms with locations in 4 states.
I was in TN. When a system would go down in SC or NC, we originally had three options:
I got sick of this. So I researched options and found an open source software solution called FOG. I ran a server in our office and had little optiplex 160s running a software client that I shipped to each club. Then each machine at each club was configured to PXE boot from the fog client.
The server contained images of every machine we commonly used. I could tell FOG which locations used which models, and it would keep the images cached on the client machines.
If everything was okay, it would chain the boot to the os on the machine. But I could flag a machine for reimage and at next boot, the machine would check in with the local FOG client via PXE and get a complete reimage from premade images on the fog server.
The corporate office was physically connected to one of the clubs, so I trialed the software at our adjacent club, and when it worked great, I rolled it out company wide. It was a massive success.
So yes, I could completely reimage a computer from hundreds of miles away by clicking a few checkboxes on my computer. Since it ran in PXE, the condition of the os didn’t matter at all. It never loaded the os when it was flagged for reimage. It would even join the computer to the domain and set up that locations printers and everything. All I had to tell the low-tech gymbro sales guy on the phone to do was reboot it.
This was free software. It saved us thousands in shipping fees alone. And brought our time to fix down from days to minutes.
There ARE options out there.
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.
It also assumes that reimaging is always an option.
Yes, every company should have networked storage enforced specifically for issues like this, so no user data would be lost, but there's often a gap between should and "has been able to find the time and get the required business side buy in to make it happen".
Also, users constantly find new ways to do non-standard, non-supported things with business critical data.
Isn't this just more of what caused the problem in the first place? Namely, centralisation. If you store data locally and you lose a machine, that's bad but not the end of the world. If you store it centrally and you lose the data, that's catastrophic. Nassim Taleb nailed this stuff. Keep the downside limited, and the upside unlimited or as he says, "Don't pick up pennies in front of a steamroller."
