7/18/24 10:20PM PT - Hello everyone - We have widespread reports of BSODs on windows hosts, occurring on multiple sensor versions. Investigating cause. TA will be published shortly. Pinned thread.

SCOPE: EU-1, US-1, US-2 and US-GOV-1

Edit 10:36PM PT - TA posted: https://supportportal.crowdstrike.com/s/article/Tech-Alert-Windows-crashes-related-to-Falcon-Sensor-2024-07-19

Edit 11:27 PM PT:

CrowdStrike Engineering has identified a content deployment related to this issue and reverted those changes.

Workaround Steps:

Boot Windows into Safe Mode or the Windows Recovery Environment

Navigate to the C:\Windows\System32\drivers\CrowdStrike directory

Locate the file matching “C-00000291*.sys”, and delete it.

Boot the host normally.
