Almost half a million Lloyds customers had personal data exposed in IT glitch

People’s payments, account details and national insurance numbers visible to other users, says Treasury committee

Lloyds Banking Group exposed the personal data of nearly 500,000 customers in an IT glitch that left people’s payments, account details and national insurance numbers visible to other users, a committee of MPs has revealed.

A letter from Lloyds, published by MPs on the Treasury select committee on Friday, blamed the glitch on a software defect introduced during an IT update to its Lloyds, Halifax and Bank of Scotland mobile banking apps overnight into 12 March.
