You're correct. Full of zeros at least.

…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.

    This was a binary configuration file of some sort though?

    Something along the lines of:

    IF (config.parameter.read == garbage) {
     Dont_panic;
}

    Would have helped greatly here.
