CrowdStrike downtime apparently caused by update that replaced a file with 42kb of zeroes (twiiit.com)

…according to a Twitter post by the Chief Informational Security Officer of Grand Canyon Education.

So, does anyone else find it odd that the file that caused everything CrowdStrike to freak out, C-00000291-
00000000-00000032.sys was 42KB of blank/null values, while the replacement file C-00000291-00000000-
00000.033.sys was 35KB and looked like a normal, if not obfuscated sys/.conf file?

Also, apparently CrowdStrike had at least 5 hours to work on the problem between the time it was discovered and the time it was fixed.

From my experience it was more likely to be an accidental overwrite from human error with recent policy changes that removed vetting steps.

this is what I suspect also. I mean it's easy to point fingers at George Kurtz as he was CTO at Mcafee when they had their "little" snafu but...well...yeah. I strongly suspect many of his "policies" he had while CTO at Mcafee carried over to Crowdstrike. dude isn't exactly known for being a fan of testing or vetting processes. in fact he's all about quick development/crunch.

Quick development will probably spell the end of the internet once AI code creation hits its stride. It'll be like the most topheavy SCRUM you've ever seen with the devs literally incapable of disagreeing.

I was thinking about his stint at McAfee, and I think you're right. My real question is: will the next company he golden parachutes off to learn the lesson?

I'm going to bet not.
