BEDFORD, Texas (3/18/08)--An ATM hack attack at Omni-American Bank (formerly Omni-American CU) has spread, affecting members at other financial institutions, including credit unions. Fort Worth Community CU members who used their debit cards at ATMs owned by OmniAmerican Bank reported unusual activity on their accounts to the credit union, Diane Dorsey, vice president of operations at Fort Worth Community CU told News Now. When Fort Worth Community CU first received the reports of suspicious activity, it reissued members new cards. It also checked the unusual activity for common denominators and found that the affected members had used OmniAmerican ATMs. “It was not a breach of our system,” Dorsey emphasized. About 50 members of Forth Worth Community CU reported suspicious activity. “The effects were really quite limited,” Dorsey said. Omni-American Bank ATMs had stored card data “that they were not supposed to,” Dorsey said, so when the data system was hacked into, the hackers were able to use cardholders’ information to make purchases. OmniAmerican replaced about 40,000 cards, Dorsey added. The ATM hacking also spread to Naval Air Station Fort Worth--whose victims had accounts at Bank of America, USAA and Navy FCU in Vienna, Va.
