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 I send you on stage at the Olympic Games opening ceremony with a sealed envelope

And I say "This contains your script, just open it and read it"

And then when you open it, the script is blank

You're gonna freak out

Ah, makes sense. I guess a driver would completely freak out if that file gave no instructions and was just like "..."
