This is an unpopular opinion, and I get why – people crave a scapegoat. CrowdStrike undeniably pushed a faulty update demanding a low-level fix (booting into recovery). However, this incident lays bare the fragility of corporate IT, particularly for companies entrusted with vast amounts of sensitive personal information.
Robust disaster recovery plans, including automated processes to remotely reboot and remediate thousands of machines, aren’t revolutionary. They’re basic hygiene, especially when considering the potential consequences of a breach. Yet, this incident highlights a systemic failure across many organizations. While CrowdStrike erred, the real culprit is a culture of shortcuts and misplaced priorities within corporate IT.
Too often, companies throw millions at vendor contracts, lured by flashy promises and neglecting the due diligence necessary to ensure those solutions truly fit their needs. This is exacerbated by a corporate culture where CEOs, vice presidents, and managers are often more easily swayed by vendor kickbacks, gifts, and lavish trips than by investing in innovative ideas with measurable outcomes.
This misguided approach not only results in bloated IT budgets but also leaves companies vulnerable to precisely the kind of disruptions caused by the CrowdStrike incident. When decision-makers prioritize personal gain over the long-term health and security of their IT infrastructure, it’s ultimately the customers and their data that suffer.
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:
- (The most common) have them put it in a box and ship it to me.
- I go there and fix it (rare)
- I walk them through fixing it over the phone (fuck my life)
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.
How would it not have? You got an office or field offices?
“Bring your computer by and plug it in over there.” And flag it for reimage. Yeah. It’s gonna be slow, since you have 200 of the damn things running at once, but you really want to go and manually touch every computer in your org?
The damn thing’s even boot looping, so you don’t even have to reboot it.
I’m sure the user saved all their data in one drive like they were supposed to, right?
I get it, it’s not a 100% fix rate. And it’s a bit of a callous answer to their data. And I don’t even know if the project is still being maintained.
But the post I replied to was lamenting the lack of an option to remotely fix unbootable machines. This was an option to remotely fix nonbootable machines. No need to be a jerk about it.
But to actually answer your question and be transparent, I’ve been doing Linux devops for 10 years now. I haven’t touched a windows server since the days of the gymbros. I DID say it’s been a decade.
Because your imaging environment would also be down. And you’re still touching each machine and bringing users into the office.
Or your imaging process over the wan takes 3 hours since it’s dynamically installing apps and updates and not a static “gold” image. Imaging is then even slower because your source disk is only ssd and imaging slows down once you get 10+ going at once.
I’m being rude because I see a lot of armchair sysadmins that don’t seem to understand the scale of the crowdstike outage, what crowdstrike even is beyond antivirus, and the workflow needed to recover from it.
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.
Absolutely. 100%
But don’t let perfect be the enemy of good. A fix that gets you 40% of the way there is still 40% less work you have to do by hand. Not everything has to be a fix for all situations. There’s no such thing as a panacea.
Sure. At the same time one needs to manage resources.
I was all in on laptop deployment automation. It cut down on a lot of human error issues and having inconsistent configuration popping up all the time.
But it needs constant supervision, even if not constant updates. More systems and solutions lead to neglect if not supplied well. So some “would be good to have” systems just never make the cut, because as overachieving I am, I’m also don’t want to think everything is taken care of when it clearly isn’t.
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.”
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.
This is a good solution for these types of scenarios. Doesn’t fit all though. Where I work, 85% of staff work from home. We largely use SaaS. I’m struggling to think of a good method here other than walking them through reinstalling windows on all their machines.
- Configure PXE to reboot into recovery image, push out command to remove bad file. Reboot. Done. Workstation laptops usually have remote management already.
or
- Have recovery image already installed. Have user reboot & push key to boot into recovery. Push out fix. Done.
That’s still 15% less work though. If I had to manually fix 1000 computers, clicking a few buttons to automatically fix 150 of them sounds like a sweet-ass deal to me even if it’s not universal.
You could also always commandeer a conference room or three and throw a switch on the table. “Bring in your laptop and go to conference room 3. Plug in using any available cable on the table and reboot your computer. Should be ready in an hour or so. There’s donuts and coffee in conference room 4.” Could knock out another few dozen.
Won’t help for people across the country, but if they’re nearish, it’s not too bad.
