…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.
Windows assumes that you installed that AV for a reason. If it suddenly faults, who’s to say it’s a bug and not some virus going ham on the AV? A BSOD is the most graceful exit you could do, ignoring and booting a potentially compromised system is a fairly big no-no (especially in systems that feel the need to install AV like this in the first place).
