Full breach record for TEXAS DOW EMPLOYEES CREDIT UNION →

Texas Dow Employees Credit Union notified the California Attorney General of a data breach affecting members. The incident occurred between May 29 and May 31, 2023, resulting from a vulnerability exploited in the MOVEit file transfer software provided by Progress Software. The breach did not result from a compromise of TDECU's own systems but rather through this third-party supply chain vector. Affected data likely includes personal identifiers and financial information. TDECU is offering 24 months of complimentary Experian IdentityWorks credit monitoring to affected individuals.
