Indian Government’s CERT-In Issues Urgent Advisory and ‘Quick-Fix’ on Global Cyber Outage Linked to CrowdStrike’s Update

New Delhi – The Indian Computer Emergency Response Team (CERT-In) has issued a critical advisory following reports that a recent update to the CrowdStrike Falcon Sensor has led to widespread outages and crashes in Windows hosts. The advisory, designated CIAD-2024-0035, highlights that affected systems are experiencing the dreaded Blue Screen of Death (BSOD).

The issue arose after a recent update to the CrowdStrike Falcon Sensor, which is widely used for endpoint protection. The update has caused Windows systems to crash, rendering them inoperative. CrowdStrike has since reverted the problematic changes, but many systems remain affected. The advisory includes specific steps for users to mitigate the issue if their systems are still crashing:

1. Boot Windows into Safe Mode or the Windows Recovery Environment.
2. Navigate to the C:\Windows\System32\drivers\CrowdStrike directory.
3. Delete the file matching the pattern C-00000291*.sys.
4. Reboot the system normally.

CrowdStrike has acknowledged the issue and advised users to follow the outlined steps to stabilize their systems. They have also updated their support portal with the latest information and recommendations.
