Customers of Lloyds, Bank of Scotland and Halifax were able to see the transactions of other people on their apps and online banking services due to a glitch for which the banks apologised.
The “issue”, which occurred in the early hours of 12 March, resulted in users seeing, in some cases, personally identifying data such as car registration numbers and National Insurance numbers.
The banks are all owned by Lloyds Banking Group, which apologised for the issue and said it had been resolved and would be investigated.
Transaction details
One Lloyds Bank user told the BBC that he was able to scroll through the full history of another account, month by month, including direct debits to the DVLA where the car registration number was shown.
A woman in Scotland using the Bank of Scotland app said she was able to view benefits payments from the Department of Work and Pensions that displayed National Insurance numbers as a payment reference.
A user writing on social media said that each time they logged into their account, they saw transactions belonging to a different person.
Another user wrote to money expert Martin Lewis on his social media account that they were able to see transactions of other people that indicated where they worked, their wages, payments they made to schools, and payments they made to other people, including full names.
‘Issue’
“This morning we incorrectly showed transaction information from some accounts to other customers in Internet Banking and the mobile app,” Lloyds Bank told some users via social media.
“We’re sorry this happened. This issue was quickly identified and resolved.”
The bank told users no one else had access to their accounts, and added that it was reviewing what had happened to “ensure this cannot occur again”.
