11:44 AM EDT, 10/28/2024 (MT Newswires) -- Delta Air Lines ( DAL ) filed a lawsuit against CrowdStrike ( CRWD ) alleging that the cybersecurity firm "cut corners" and "took shortcuts" by running a "faulty" update that caused the July 19 global outage, according to a Friday court complaint.

The update was "catastrophic" and forced onto CrowdStrike ( CRWD ) customers, including Delta, who had not enabled automatic update settings, the company said.

The glitch "crippled Delta's operations for several days, forced thousands of flight cancellations and delays, and adversely affected more than a million Delta customers. Delta estimates that it suffered over $500 million in out-of-pocket losses from the faulty update, in addition to future revenue and severe harm to its reputation and goodwill," the company said.

Following the update, CrowdStrike ( CRWD ) conceded that it did not properly test its programming and data changes and failed to roll out the faulty update in stages, which is a standard practice in software development, the complaint added.

The case was filed at the Fulton County Superior Court in Georgia. CrowdStrike ( CRWD ) did not immediately respond to MT Newswires' request for comment.
