Delta Airlines has officially filed a lawsuit against CrowdStrike, the cybersecurity company responsible for the world's largest IT outage. The outage, caused by a faulty driver in an update to CrowdStrike's Falcon sensor, resulted in millions of Windows machines being thrown into boot loops, significantly impacting Delta Airlines' operations.

Delta Airlines CEO, Ed Bastian, has previously accused CrowdStrike of causing the catastrophic IT failure, leading to the manual reset of 40,000 servers and the cancellation of over 7,000 flights. The airline claims to have sustained approximately $500 million in damages from the outage.

In its complaint, Delta Airlines states that CrowdStrike's actions led to a global catastrophe due to corners being cut and shortcuts taken, bypassing the testing and certification processes. CrowdStrike, however, disputes Delta's claims, suggesting that the airline's slow recovery is due to its failure to modernize its IT infrastructure.
