Waking up to a major CrowdStrike issue locking up machines. The fix updated from CrowdStrike: - -For Individual Hosts - - First Try: Rebooting the host to give it an opportunity to download the reverted channel file.?If the host crashes again, then: If Not Successful: 1. Boot Windows into Safe Mode or the Windows Recovery Environment **Note:?Putting the host on a wired network (as opposed to WiFi) and using Safe Mode with Networking can help remediation.? 2. Navigate to the %WINDIR%\System32\drivers\CrowdStrike directory Locate the file matching “C-00000291*.sys”, and delete it. Boot the host normally. Note: Bitlocker-encrypted hosts may require a recovery key. -- For Public Cloud and Virtual Systems -- Option 1: 1. Detach the operating system disk volume from the impacted virtual server 2. Create a snapshot or backup of the disk volume before proceeding further as a precaution against unintended changes 3. Attach/mount the volume to to a new virtual server 4. Navigate to the %WINDIR%\\System32\drivers\CrowdStrike directory 5. Locate the file matching “C-00000291*.sys”, and delete it. 6. Detach the volume from the new virtual server 7. Reattach the fixed volume to the impacted virtual server Option 2: 1. Roll back to a snapshot before 0409 UTC. Note: -Channel file "C-00000291*.sys" with timestamp of 0527 UTC or later is the reverted (good) version. -Channel file "C-00000291*.sys" with timestamp of 0409 UTC is the problematic version.
