How a software update from cyber firm CrowdStrike caused one of the world’s biggest IT blackouts

A software update by cybersecurity firm CrowdStrike caused widespread IT outages across various sectors, including banking, healthcare, and air travel. Global disruptions ensued as both businesses and consumers faced significant service interruptions. The issue stemmed from a problem in CrowdStrike's Falcon product, leading to devices running Windows operating systems to crash with the "blue screen of death." The company is currently working to roll back the problematic update. Microsoft clarified that their prior cloud service outage was unrelated. While CrowdStrike announced that a fix was in progress, experts noted that the recovery process might require significant manual intervention.
