More cards are at risk from the Global Payments card data breach than had previously beensuspected, according to CUNA Mutual Insurance, the firm which insures the bulk ofcredit union card programs.

The firm has alerted credit unions to the possibility of greatercard losses from both card-present and card-not-present fraud sincethe Global Payments breach has been determined to have started onJan. 30, 2011.

The company has not previously made public a date for when thebreach was supposed to have begun after news of it broke lastmonth.

The insurer said the additional time meant that more cards areat risk for both card-not-present and card-present fraud.

“Credit unions experiencing card fraud since January 2011 shouldreview 'card-present' and 'card-not-present' fraud and confirm thefraud cases have been reported to the card association(s)” theinsurer told covered CUs. “This will assist the card association(s)in determining whether the fraud is tied to the Global Paymentsbreach.

“Credit unions that have identified a common point of purchaseshould report it to the card association(s). As a reminder, creditunions experiencing 'card-present' or 'card-not-present' fraudshould continue to exercise available chargeback rights.”
