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.

The outage only affected the Windows version of Falcon. OSX and Linux were not affected.

This time. Last time it did affect Linux. It doesn't have anything to do with Microsoft.
Sorry to burst your bubble.

what are you on about? who suggested anything about microsoft?

Windows kernel drivers are signed by Microsoft. They must have rubber stamped this for this to go through, though.

Try to keep up.

Quoting the comment that started this thread is speaking like a child to you?

In this thread we're talking about the recent problem with CrowdStrike on Windows that brought down various services around the world. So I don't know who's bubble you think you're bursting by talking about something else.
