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.

Oooooooo this one again thank you for reminding me

That one turns out to have been largely Microsoft's fault for repeatedly ignoring warnings of a severe vulnerability relating to Active Directory. Microsoft were warned about it, acknowledged it and ignored it for years until it got used in the Solar Winds hack.
