“CrowdStrike said it also plans to move to a staggered approach to releasing content updates so that not everyone receives the same update at once, and to give customers more fine-grained control over when the updates are installed.”
Hol up. So they like still get to exist? Microsoft and affected industries just gonna kinda move past this?
Newsflash, Solarwinds still exists too. Not sure I could name a company that screwed up so big and actually paid the price.
Two days ago my company sent out an all hands email that we’re going company wide with Crowdstrike.
I wasn’t effected but I bet a lot of admins, as pissed as they were, were thinking “I could easily fuck up this bad or worse”.
Yeah, what’s the jokey parable thing?
A CTO is at lunch when a call comes in. There’s been a huge outage, caused by a low level employee pressing the wrong button.
“Damn, you going to fire that guy?”
“Hell no, do you know how much I just spent on training him to never do that again?”
(</Blah>)
Companies using CrowdStrike and Windows aren’t really the type to be active about this sort of thing.
The companies who use CrowdStrike (lazy fix) on Windows (garbage OS) aren’t really the type to want to switch away from it (will take effort)
$5.4 Bn so far, not including lost worker productivity or damage to brand reputations, so that’s a very conservative estimate. And Cybersecurity insurance will supposedly only cover up to 20% of that (but good luck getting even that much). What a clusterf***
No it’s all of them because all the companies combined out side of the 500 wouldn’t even have enough net worth large enough to move the needle. So technically they may not be included but would be covered by whatever amount they rounded up to make the even 5.4b
All the CrowdStrike companies on earth minus the 500 biggest (American) ones? I have a hard time believing it’s as insignificant as you assume. I guess we’ll see…
On Wednesday, CrowdStrike released a report outlining the initial results of its investigation into the incident, which involved a file that helps CrowdStrike’s security platform look for signs of malicious hacking on customer devices.
The company routinely tests its software updates before pushing them out to customers, CrowdStrike said in the report. But on July 19, a bug in CrowdStrike’s cloud-based testing system — specifically, the part that runs validation checks on new updates prior to release — ended up allowing the software to be pushed out “despite containing problematic content data.”
…
When Windows devices using CrowdStrike’s cybersecurity tools tried to access the flawed file, it caused an “out-of-bounds memory read” that “could not be gracefully handled, resulting in a Windows operating system crash,” CrowdStrike said.
Couldn’t it, though? 🤔
And CrowdStrike said it also plans to move to a staggered approach to releasing content updates so that not everyone receives the same update at once, and to give customers more fine-grained control over when the updates are installed.
I thought they were already supposed to be doing this?
The fact that they weren’t already doing staggered releases is mind-boggling. I work for a company with a minuscule fraction of CrowdStrike’s user base / value, and even we do staggered releases.
They do have staggered releases, but it’s a bit more complicated. The client that you run does have versioning and you can choose to lag behind the current build, but this was a bad definition update. Most people want the latest definition to protect themselves from zero days. The whole thing is complicated and a but wonky, but the real issue here is cloudflare’s kernel driver not validating the content of the definition before loading it.
Makes sense that it was a definitions update that caused this, and I get why that’s not something you’d want to lag behind on like you could with the agent. (Putting aside that one of the selling points of next-gen AV/EDR tools is that they’re less reliant on definitions updates compared to traditional AV.) It’s just a bit wild that there isn’t more testing in place.
It’s like we’re always walking this fine line between “security at all costs” vs “stability, convenience, etc”. By pushing definitions as quickly as possible, you improve security, but you’re taking some level of risk too. In some alternate universe, CS didn’t push definitions quickly enough, and a bunch of companies got hit with a zero-day. I’d say it’s an impossible situation sometimes, but if I had to choose between outage or data breach, I’m choosing outage every time.
Couldn’t it, though? 🤔
IANAD and AFAIU, not in kernel mode. Things like trying to read non existing memory in kernel mode are supposed to crash the system because continuing could be worse.

It is time to write tests for tests!

Always blame the tests. There are so many dark patterns in this industry including blaming qa for being the last group to touch a release, that I never believe “it’s the tests”.
There’s usually something more systemic going on where something like this is missed by project management and developers, or maybe they have a blind spot that it will never happen, or maybe there’s a lack of communication or planning, or maybe they outsourced testing to the cheapest offshore providers, or maybe everyone has huge time pressure, but “it’s the tests”
Ok, maybe I’m not impartial, but when I’m doing a root cause on how something like this got out, my employer expects a better answer than “it’s the tests”
Oh, finally, I have been waiting for so long.
All because of one guy!!!
