A faulty update to CrowdStrike Falcon, an endpoint protection service, caused a widespread IT outage on July 19th. The update triggered a logic error that led to system crashes and the blue screen of death on affected Windows devices. CrowdStrike has since corrected the issue and systems are returning to normal. This incident highlights the importance of thorough testing before deploying security software updates.

CrowdStrike said that sensor configuration updates were an "ongoing part of the protection mechanisms of the Falcon platform"-its endpoint protection service. 

"The update that occurred at 04:09 UTC was designed to target newly observed, malicious named pipes being used by common C2 frameworks in cyberattacks. The configuration update triggered a logic error that resulted in an operating system crash," noted CrowdStrike.
