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.

If it had been all ones this could have been avoided.

Just needed to add 42k of ones to balance the data. Everyone knows that, like tires, you need to balance your data.

Apply the ones in a star shape to distribute pressure evenly

I mean, joking aside, isn't that how parity calculations used to work? "Got more uppy bits than downy bits - that's a paddlin'" or something.

Imagine the world if those companies were using Atomic distribution and the only thing you would need to do is to boot the previous good image.
