Delta Air Lines has initiated a lawsuit against cybersecurity firm CrowdStrike following a global technology outage caused by a faulty update in July that resulted in 7,000 flight cancellations and over $500 million in losses. Delta accuses CrowdStrike of negligence, claiming the company deployed untested software, which led to significant disruptions not only for the airline but for other industries worldwide. CrowdStrike contests Delta’s claims, asserting that they are based on misinformation and reflect a misunderstanding of cybersecurity protocols, while a U.S. Department of Transportation investigation is underway regarding the incident and Delta's recovery time.
