…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 had to bet my money, a bad machine with corrupted memory pushed the file at a very final stage of the release.

The astonishing fact is that for a security software I would expect all files being verified against a signature (that would have prevented this issue and some kinds of attacks

So here's my uneducated question: Don't huge software companies like this usually do updates in "rollouts" to a small portion of users (companies) at a time?

I mean yes, but one of the issuess with "state of the art av" is they are trying to roll out updates faster than bad actors can push out code to exploit discovered vulnerabilities.

The code/config/software push may have worked on some test systems but MS is always changing things too.

Somone else said this wasn't a case of this breaks on windows system version XXX with update YYY on a Tuesday at 12:24 pm when clock is set to eastern standard time. It literally breaks on ANY windows machine, instantly, on boot. There is no excuse for this.
