CrowdStrike Error
Massive Outage
CrowdStrike has provided a detailed analysis of the incident involving a faulty update that resulted in the failure of 8.5 million computers. The main cause of the problem is said to be an insufficient testing program.
Consequences of the error
Due to a flaw in the software, a content update that was distributed to a huge number of devices on Friday. CrowdStrike says it will take steps to more thoroughly test its product updates, improve error handling, and implement a phased rollout system to prevent similar large-scale failures in the future.
Falcon Software Features
CrowdStrike's Falcon software product is widely used by companies around the world for anti-malware and security applications on millions of computers running the Windows operating system. On Friday, the company released a configuration update for its product aimed at "collecting telemetry on potential new threat techniques." Even though such updates are released regularly, this particular update caused Windows to crash.
Update Process
CrowdStrike typically releases configuration updates in two ways. The first is the so-called Sensor Content, which directly updates CrowdStrike Falcon running at the Windows kernel level. The second is quick response content, which modifies malware detection algorithms. It was a small Rapid Response Content file, just 40 KB in size, that caused Friday's incident. Last week, CrowdStrike released two rapid response updates that the company calls template instances.
Cause of failure
CrowdStrike explains: "Due to an error in the content validation tool, one of the two template instances passed validation , despite the presence of problematic data." Although CrowdStrike conducts both automated and manual testing, it has proven to be ineffective. The introduction of new template types in March led to "confidence in the checks performed by the Content Validator," so CrowdStrike likely assumed the rollout would go smoothly.
Technical Details
CrowdStrike explains: "This unexpected exception was not handled correctly, causing the Windows operating system to crash ( BSOD)".
Prevention Measures
To prevent similar incidents in the future, CrowdStrike promises to improve its rapid response content testing process. This includes testing by local developers, testing content updates and rollback procedures, and stress testing. In addition, CrowdStrike plans to conduct stability and interface testing of Rapid Response Content, as well as updates to its cloud-based validation tool.
