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.

Years ago I read an study about insurance companies and diversification of assets in Brazil. By regulation, an individual insurance company need to have a diversified investment portfolio, but the insurance market as a whole not. the diversification of every individual company sum, as a whole of all the insurance market, as an was exposed market, and the researchers found, iirc, like 3 banks that if they fail they can cause a chain reaction that would take out the entire insurance market.

Don't know why, but your comment made me remind of that.

That's kind of fascinating, never considered what the results of that kind of regulation can bring without anyone even noticing it at the time. Thanks for a good reading topic for lunch!
