Snowflake Customer Data Breach Litigation (AT&T, Ticketmaster)
Case Overview
Beginning in April 2024, hackers exploiting credential vulnerabilities in Snowflake Inc.'s cloud data platform executed one of the largest data breach campaigns in history, successfully infiltrating the cloud storage accounts of over 160 major corporations. High-profile victims included AT&T (affecting approximately 110 million customers), Ticketmaster/Live Nation (affecting roughly 560 million users), Advance Auto Parts, LendingTree, and Neiman Marcus, among others. The stolen data included names, Social Security numbers, phone numbers, addresses, call records, payment card information, and account credentials.
Plaintiffs filed class action lawsuits against both Snowflake and the affected corporate clients, alleging failures to implement multi-factor authentication, adequate access controls, and industry-standard security protocols despite handling vast quantities of sensitive consumer data. The AT&T-related litigation alone encompasses virtually the entire U.S. mobile customer base. Plaintiffs allege violations of state data protection laws, negligence, breach of implied contract, and unjust enrichment. The cases are in early stages, with consolidation proceedings underway in multiple federal courts.
