…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.

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?

Companies don't like to be beta testers. Apparently the solution is to just not test anything and call it production ready.

Every company has a full-scale test environment. Some companies are just lucky enough to have a separate prod environment.

I'm a bit rusty. I'd give it a C++.
