LONDON - 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.

Friday's outage happened because CrowdStrike's Falcon Sensor, an advanced platform that protects systems from malicious software and hackers, contained a fault that forced computers running Microsoft's Windows operating system to crash and show the "Blue Screen of Death".
