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.

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.
