On July 19, 2024, CrowdStrike released a flawed Microsoft Windows software update that caused widespread system failures:
- The update was pushed to CrowdStrike’s Falcon monitoring product.

Root Cause Analysis
CrowdStrike’s CEO, George Kurtz, provided insights into what went wrong:
- The issue stemmed from a single configuration file pushed as an update to Falcon.
- The update was aimed at changing how Falcon inspects “named pipes” in Windows.
- This change was intended to catch a new method hackers were using for malware communication.
- The configuration update triggered a logic error, resulting in operating system crashes.
It’s important to note that this was not a cyberattack, but rather a technical glitch in the update process.
Recovery Steps
If your systems are affected, follow these steps to recover:
- 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”
- Reboot normally.
For large organizations, this process may need to be repeated manually for each affected system, which could take considerable time.
