This resulted in several Microsoft Windows devices showing the ‘blue screen of death’, leading to system crashes and disruptions across businesses such as airlines, banks, retailers, media companies and stock markets, to name a few.
CrowdStrike has acknowledged the problem and is working on a solution. While some systems have reportedly recovered, the full extent of the damage and recovery timeline remains unknown.
