On July 19, 2024, many organizations experienced significant disruptions due to a critical issue with CrowdStrike’s Falcon Sensor. This incident resulted in Blue Screen of Death (BSOD) errors, causing a global IT outage that impacted businesses relying on CrowdStrike for endpoint security.
What Happened?
The issue was caused by a bug in an update to the CrowdStrike Falcon Sensor, which led to BSOD errors across multiple systems. This disruption caused significant downtime and operational inefficiencies. Falcon Sensor is an agent designed to block attacks on systems while capturing and recording real-time activity to detect threats quickly. Unfortunately, in this instance, the sensor itself caused system crashes due to the faulty update.
CrowdStrike quickly acknowledged the problem and worked on a fix to prevent further issues.
The Fix
CrowdStrike’s chief threat hunter, Brody Nisbet, provided a temporary workaround to address the issue:
- Boot Windows into Safe Mode or Windows Recovery Environment (WRE).
- Navigate to
C:\Windows\System32\drivers\CrowdStrike. - Locate and delete the file matching “C-00000291*.sys”.
- Boot the system normally.
