…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.

This was a binary configuration file of some sort though?

Something along the lines of:

IF (config.parameter.read == garbage) {
     Dont_panic;
}

Would have helped greatly here.

Edit: oh it's more like an unsigned binary blob that gets downloaded and directly executed. What could possibly go wrong with that approach?

We agree, but they were responding to “windows apparently has zero execution integrity”.
