Do you think Microsoft customers using CrowdStrike would then be happier, being unable to run the software at all, due to an action Microsoft took? Backdoors of all kinds can be installed to most any operating system without vendor co-operation. That is the nature of general-purpose operating systems.

I'm a customer that is forced to use CrowdStrike via IT policies and I would be giddy with delight if something came along and caused the removal of it from my systems. I don't need programs sitting on my computer preventing me from installing code that I've literally just compiled, preventing me from deleting or modifying folders on my machine, and causing extreme lag for many basic system operations even when it does work. At this point, the time in lost productivity (via normal operation) and downtime (via their recent bug) has easily exceeded a thousand times over the aggregate sum of all benefits that CrowdStrike will ever have provided from threat detection and prevention. It's time to remove the malware.

  You are not the customer, though, your employer is the customer. Perhaps you should push this change up in the food chain, then, and if the company is good the request will be taken seriously. As I understand it, while CrowdStrike is the biggest name in EDR, it's far from the only one, if that's what your company requires to pass some checkboxes in certifications.

    Vendors are competing with one and another to win contracts. CIO/CISO don't select vendors lightly. There seems to be a typical/classical Engineer's mindset of "make a claim first, ask later" around the subject lately. "My boss plays golf with Sales Rep" might need more proof because if they selected the lesser capable vendors and they got hit with ransomware, bet my ass your boss will no longer play Golf with any Sales Rep ever.

      > Vendors are competing with one and another to win contracts. Sure, in a well-functioning market economy without any distortions. But there are lots of those at play, so competition is severely hampered (by network effects, regulatory capture, and on and on... Up to and including, I suspect, mere ephemeral fashion). What we actually have in many areas of the "tech market" are oligopolies and near-monopolies, not perfect competition. > CIO/CISO don't select vendors lightly. Muahaha. Seems rather more like they're at least as naïve as any Web-surfing consumer on their sofa, easily bamboozled by trendy buzzwords and slick marketing campaigns.

  Sounds like your IT (sec team, specifically) doesn't setup the software correctly. I've worked for a company that installs Falcon on all its fleet and I never run into issues like yours.

At this point… yes. It would be one thing Microsoft could do to focus 100% of the attention/blame away from Windows and onto CloudStrike. And customers will want their pound of flesh from somewhere. Really, this should serve as a wake up call w/in Microsoft to start to harden the kernel against such vulnerabilities. Was the crash the fault of Windows? No. But did a Windows design decision make this possible? yes. I’m sure the design decision made sense at the time (at least business sense). Keeping the kernel more open for others to add drivers to makes it easier to write/add drivers, but makes the system more vulnerable. This a good opportunity within Microsoft to get support for changing that.

  Ultimately this would have been almost a non-issue if there had been better deployment strategies in place for also the data file updates. If by changing the system you mean adding some kind of in-kernel isolation to it, then I don't think it would be worth the effort to make that kind of major change to the way operating systems work just to give arguably a minor risk reduction to systems—in particular if CrowdStrike and other vendors take some learnings from this event. Microsoft might improve their system rollback mechanism to also include files that are not strictly integrated to the system, merely used by the parts that are (the channel files loaded by the driver). Actually I think we can just be happy that the incident was a mistake, not an attack. Had this kind of "first ever" situation been an attack, it could be extremely difficult to recover from it. I wonder how well EDRs deal with "attacks from within".. CrowdStrike pulled off the update within 1.5 hours. I wonder if they actually use Falcon themselves? But then somehow missed the problem? Doesn't seem like they eat their own dog food :). (Or at least their own channel files.)

    If many things had gone differently, this could have been avoided. But I’m looking at this from the Microsoft perspective. No matter how much people scream high and loud that it was a CloudStrike issue and not Microsoft’s fault, Microsoft is still getting blamed. It’s a Windows BSOD. I talked to my dad (retired enterprise operations/IT) this weekend and he was telling me that the next computer he buys will probably be a Mac, largely because he doesn’t want to deal with the possibility of a crash like this. Does he run CloudStrike? Not at all. Does he know who they are? Nope. (He’s been retired for a while) What he does know (well, thinks) is that Windows now has an unstable kernel. And Microsoft has no control over distribution policies for other vendors. How those vendors distribute updates is up to them. Even if a sane deployment strategy could have avoided the larger global problems, Microsoft can’t control that. So, if you have Microsoft dealing with negative publicity and public sentiment, with no way to control errors like this in the future, what can you do? To me, the best they can do is kneecap CloudStrike, put the full blame on them, and use this as an excuse to change the kernel/driver model to one where they can have more control over the stability of the OS.

  How much does it really help you if your complete user-space can still be messed up by an offending Windows SYSTEM process? As I understand it, they are able to hurt the system e.g. by killing processes, uninstalling applications, replacing binaries, allocating memory, starting too many processes, .. Actually I could easily see a buggy remote system management update could just decide to uninstall everything and nuke the system, because it thinks it's stolen. And it would be designed functionality for it.
