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.

I disagree. I'd rather things crash than silently succeed or change the computation. They should have done better input and output validation, and gracefully fail into a recoverable state that sends a message to an admin to correct. A divide by zero doesn't crash a system, it's a recoverable error they should 100% detect and handle, hot sweep under the rug.

Life pro tip: if you're a python programmer you should use try: func() except: continue every time you run a function, that way ypu would never have errors on your code.
