A CrowdStrike software update that crashed computers globally last week hitting services from aviation to banking and healthcare was caused by a bug in the U.S. cybersecurity firm's quality control mechanism, the company said on Wednesday. "Due to a bug in the Content Validator, one of the two Template Instances passed validation despite containing problematic content data," CrowdStrike said in a statement, referring to the failure of an internal quality control mechanism that allowed the problematic data to slip through the company's own safety checks. CrowdStrike did not say what that content data was, nor why it was problematic. CrowdStrike said it had added a "new check" to its quality control process in a bid to prevent the issue from occurring again. Wednesday's statement was in line with a widely held assessment from cybersecurity experts that something in CrowdStrike's quality control process had gone badly wrong.
