UK Banks Expose Customer Transactions in Mobile Apps Causing Nationwide Alarm

Customers of Lloyds, Halifax, and Bank of Scotland woke up to an alarming surprise on Thursday morning: their mobile banking apps were showing transactions, balances, and payment details that did not belong to them.

The technical glitch, which emerged between 7am and 9am, triggered a wave of confusion and concern among users.

How the Glitch Unfolded

Reports began surfacing on social media, with customers posting screenshots of other people’s payments, account balances, and even sort codes.

One Lloyds customer revealed that they could see “the current balance, all transactions, including the name, sort code, and account number” linked to another account. Similarly, a Bank of Scotland user reported seeing a payment of over £36,000 alongside random names.

Halifax users also experienced the issue, with some accounts showing different statements each time they logged in.

Outage tracking site Downdetector.com recorded a significant spike in complaints about all three banking apps during the morning hours.

Banks Respond Swiftly

Lloyds Banking Group issued a public apology and confirmed the problem had been swiftly resolved, though an investigation is ongoing to understand how many customers were affected.

Halifax acknowledged that some users were experiencing issues with viewing transactions and balances, while Bank of Scotland described the incident as a potential “technical glitch” that is being investigated.

Spokespeople from all three banks emphasized that the situation had been addressed promptly and advised customers to report any unusual account activity.
