I understand from reliable sources, IT techs that understand servers, laptops and such, that the reason that only Microsoft systems were affected is that Falcon must communicate with the Microsoft kernel, the lowest level of the Operating System. Corruption in the kernel causes failure of the whole OS and must be restored in safe system mode. Linux and MacOS operation systems do not allow applications to communicate directly and so cannot be corrupted by a wayward application. Only the wayward application will fail on Linux and MacOS and could be easily rolled back to the original application. The Mac OS was rewritten some years ago to a Linux/Unix type architecture. I wonder if there is any kernel protection that will be implemented in the Microsoft OS anytime soon.

If you have VMWare, you could fire up a VM that has PowerCLI, shut down all the windows VM's, then loop through every disk image to mount it on the new VM, delete that file and unmount it again. PROBABLY best to use a Linux VM for this as Linux is far 'nicer' when it comes to mounting and unmounting drives. I'm GUESSING other hypervisors would have similar tools. HyperV shops will probably be an even bigger level of screwed with dataloss due to the hypervisors themselves resetting. Then there's next level screwed if bitlocker is in use.

To provide greater clarity, the primary issue here is that cloudstrike falcon runs at kernel level and has internet connected privileged binaries so as to provide rolling updates to threat protection offerings. This was and always has been a massive attack vector that’s yet to have been exploited at a high level. It just so happens to have exposed its vulnerability to the world through incompetence. If Microsoft was half intelligent they’d step in and implement something similar to Apple who provides a system extension abstraction layer so as to not give direct kernel access. They will not do this, because they are stupid arrogant and lazy. Instead, I think most critical organizations should steer clear of crowdstrike and similar kernel level applications with internet dependent binaries. Even if that leaves you slightly more vulnerable to other threats.

Fantastic video! I loved how you told the story of how it began at your org. That's exactly how I felt. What I suspect is going to come out of this is that CrowdStrike may have to segment its solution updates by industry. This failure was massive and even though they will check it countless times going forward, my guess is that companies will come forward and say that this cannot happen again. Just the fact that they test, test, test, and re-test going forward will not be enough. We saw a lot of side channel attacks coming in the form of phishing. While the event was not malicious, it did have somewhat the same net result and that is unavailability of services. What's also got put out front and center is, all the major companies that use Crowdstrike. I am sure that going forward they will test the hell out of their updates, but segmentation by industry is probably where they will need to go for rolling out global updates so that things like Healthcare or Travel are not impacted at the same time in the event of an issue. This will also place more focus on Microsoft Azure. While it's not Microsoft's fault, we will need to start planning for DR scenarios that we once thought were pie in the sky issues. Now those pie in the sky scenarios are real. Very real.
@2GuysTekАй бұрын
I appreciate it! We also saw a MASSIVE jump in targeted Crowdstrike phishing emails-don't let any good tragedy go to waste, I suppose. I also agree that there needs to be more opt-in for updates, like the update rings for betas of Windows, for example. It's a tough position to be in because, in the event of aggressive malicious attacks, you wanna get your protection ASAP, and that typically means pushing it as soon as you can. But the reach and the fact that Crowdstrike only services businesses (and big ones at that) means that from a supply chain perspective, it's also an incredibly massive risk, as we've now seen first-hand.

One thing I still don't understand is how this actually got out of Crowdstrike's development systems (?) and into their production deployment systems. I realize that one of the big benefits of CS is its rapid response nature, I think backed in part by ML (?), but surely there should have been some sort of internal unit test package or an equivalent to catch a killer update before it was pushed? High speed automation with no QC is an invitation to exactly this sort of disaster. Given how many medical/hospital systems were impacted, including in some locations EMS helicopter service, CS will be lucky if they don't get sued for contributing to someone's death or injury.

The only big question is why are drivers for windows not signed and then validated by the OS before being installed/loaded? That just seems so obvious. You would think there would also be a transaction log for most recently installed “system” stuff and if more than three reboots are triggered it would rollback the install log and quarantine the most recently installed items. That’s how I’ve designed patching systems in the past for mission critical infrastructure software systems. I had no idea this many people still used windows! I’ve not touched windows for 25yrs.

We don’t use CrowdStrike, but I 100% relate to your gut punch moment when you initially thought “this is it.” I’ve had that pit-of-the-stomach feeling upon seeing weird traffic in my own network several times over the last few years (so far we’re unscathed) and it truly sucks. I’m 30 years into my IT career, and the scourge of ransomware has turned what was once a fun job into an almost constant state of dread. IT is now almost 100% defense, and I hate that.

The more I read about it the more insane it becomes - it wasn't a simple bug but literally a driver file of all zeros! How the hell wasn't it hash checked by the client update process before installation and requesting a reboot ? Or how the hell did ClownStrike update push server not also do basic sanity checks before sending it to _every_ customer at the same time ? /facepalm

to an X86 Machine coder....00 is a NoOp......NoOp means no operation, and the hardware processor goes to the next instruction, which would also be a NoOp and so on until it hits code that does something. NoOps are often used in software timers where the processor loops on NoOps for a certain count, such as a millisecond delay to de-bounce a keyboard.......a processor looping on NoOps will do so forever at full speed until the power goes off.......NoOP is built into the hardware, and I assume, still cannot be changed.................not sure if this helps

@@mikedee8876 on x86 opcode 0x00 is a ADD instruction, NOP is 0x90. According to CrowdStrike Blog technical update, the .sys file is not a kernel file but a data config file. What little detail they give is not very clear as to the actual logic error that caused the crash (others have mentioned file parsing logic that resulted in a null ptr memory reference from the crash dump log).

The previous company I worked at was affected by this. I sent them the fix as soon as I read about it, as I think they were not aware of what was going on. I am lucky enough that the company I work for now does not use Crowdstrike...but honestly, this could have happen with any antimalware software. That was the case with Symantec and McAfee few years ago. Crowdstrike is still an awesome product and one of the best (if not THE best) on the market. I hope they recover from this. In my opinion, Microsoft also has some work to do in Windows following to incident to prevent something like this to happen. Windows is no where near the most robust OS...

Did not have issues at my site since we don't use Falcon, but my son's company did. I did not know that Azure did not have a console that sucks, and I was just toying with looking into it more. Whew, I dodged a bullet there. This reminds me of the MS service pack nightmare, which I did have to pull long days for. Good luck, folks. I hope you all get some sleep soon. Cheers

Really relate to your story. I’m in Australia so it hit our IT team at Friday 3pm and I’m in development (not ops) and my surface crashed, then my colleagues did. Reported it to my boss then walked away while it rebooted. In the bathroom a woman from a totally different company sharing the building with us tells me “all our pcs crashed so we’re leaving for early drinks at the pub 😂”. I was so relieved! If I’d seen the SQL servers drop first before my laptop that wouldn’t have been a fun moment to live in at all.

I do wonder why huge companies are not diversified more. It is crazy that this can happen all over the world and shut so much down. Even Crowdstrike should be fully diversified I would think where under no circumstances everything goes out to all streams on the same day. I am not IT so I don't know the terminology, but I think you know what I mean. Even in this case it seems redundancy would not have helped because it was a single bad file that went to every computer. But if out of 5000 computers, they had 5 different services or versions of a service where that are getting a different set of downloads on each stream in a single day, this would have only shut down a fifth of them, leaving only a fifth of them disabled for a bit and 80% still operational and able to find the problem before the world comes to a halt. I feel like this incident has opened floodgates and we can and likely will see malciousness on this scale or worse sooner than later. What are your thoughts?
@2GuysTekАй бұрын
You're right to question their approach. At a minimum, you'd have expected a phased approach to pushing patches, but clearly, that's not how CS was operating. A bigger question for me is how did this get past QA? This patch took down almost 100% of all of the clients who received it, with the exception of older Windows 7/Server 2008 R2. With a failure rate that high, it should have gotten caught immediately, and the fact it wasn't suggested more about how they test and validate than anything. Someone in another comment also mentioned they were surprised that CS doesn't break down update deployments based on industry, which is a good idea. Maybe businesses in critical sectors, like hospitals, don't get cutting-edge update releases the instant they're available?

My computer is stuck in an infinite reboot loop, preventing me from accessing the command prompt or deleting any files. The repair options never appear, and I've tried all the methods to enter safe mode without success. I've pressed the F keys and repeatedly forced shutdowns with the power button, but nothing works. Despite all my efforts, the computer remains in this constant reboot loop.

Loved hearing this story! Unbelievable this could not be handled without direct IT people intervening. What are you suggesting for VMs for startups that want to colocate who do not want to get locked into the Broadcom ecosystem?
@2GuysTekАй бұрын
Tough question to answer in a simple paragraph, but the short answer I would say is this - if you're a startup and you have the freedom to choose your deployments and want to take advantage of the 'cloud', I'd recommend you look for services that are cloud-first and not necessarily running on fat VMs in someone else's datacenter. But if you're looking to run VMs in a colo or in a hyperscaler like Azure, looking for providers that can offer you console access to your VMs is a huge benefit (something MS doesn't do.)
