Delta Air Lines is taking legal action against cybersecurity firm CrowdStrike, alleging that the software provider's negligence and contractual failings led to a major disruption this past July. This incident resulted in the grounding of 7,000 Delta flights and losses totaling over half a billion dollars. Delta claims that a faulty update in CrowdStrike's Falcon software spread to millions of computers running Microsoft Windows, causing severe operational disruptions. Following the July outage, Delta's revenue dropped by $380 million, and the airline incurred an additional $170 million in related costs. The recovery process dragged on for Delta, while other airlines were able to bounce back much faster. Delta, aiming to recoup its losses, has enlisted attorney David Boies to represent them in their lawsuit against CrowdStrike, and they are also seeking damages from Microsoft.
