A spokesman for PSCU has confirmed that both Visa and MasterCard have alerted it to a card data security breach and said that the CUSO began to notify participating CUs about compromised accounts last week.
Merry Pateuk said it was PSCU's standard procedure to notify credit unions as soon as possible about a potential breach and that the CUSO received its first notice of the problem in the afternoon of March 23 with subsequent notices the following day.
She did not say how many accounts so far had been listed as compromised nor could she comment on reports that the breached accounts had yielded the thieves data from both tracks one and two.
She did hold out hope that, as breaches go, the CUSO was not yet convinced that this one would be necessarily very large, but said the organization would continue monitoring the situation and advising participating credit unions about course of action regarding potentially breached accounts.
Florida-based PSCU said it now serves more than 1,500 financial institutions and 16 million credit, debit, prepaid, online bill payment, mobile and electronic banking accounts.
