You can call it an incident or a bug (many have reported it as an outage) – but it is not a breach

Delta Air Lines is suing cybersecurity firm CrowdStrike after a software incident in July led to massive flight cancellations and over $500 million in losses. The outage, affecting 1.3 million customers, caused worldwide disruptions. Delta claims the blame lies with CrowdStrike's faulty software update.

Delta Air Lines has initiated legal proceedings against cybersecurity firm CrowdStrike following a global system outage in July that resulted in widespread flight cancellations. The incident disrupted travel plans for 1.3 million passengers and inflicted financial damages exceeding $500 million on Delta.

Filed in Georgia’s Fulton County Superior Court, Delta's lawsuit blames CrowdStrike’s software update for causing catastrophic disruptions, which also impacted other industries globally. CrowdStrike has dismissed Delta’s claims as baseless, citing a lack of understanding of modern cybersecurity protocols.

CrowdStrike admitted to a configuration update causing the crashes and has expressed regret over the incident. The U.S. Transportation Department is investigating as Delta attributes the chaos to untested and irreversible software changes by CrowdStrike.
