The US’ largest bank has cancelled the debit cards of some customers following a data security breach at an undisclosed company.
Bank of America has cancelled the debit cards after being warned of the breach by the company. It is not clear at this stage whether the breach affected an on-line-based company or a high-street chain.
Bank of America has not disclosed the number of customers affected, but it has said many would have their cards cancelled and replaced as a precaution.
The investigation into the breach is ongoing, and the bank, which was the subject of its own major data security breach a year ago, said it had no evidence so far of any of its customers’ being affected.
Bank of America has written to those customers having their cards replaced, warning them to be on the look out for any unusual transactions on their statements.
The breach only affects debit cards, and not credit cards, confirmed the bank.
The Bank of America problem is the latest in a long line of high profile identity thefts and data losses to have hit corporate America in the last 18 months.
