Customers of Lloyds Banking Group reported being able to view other users' financial transactions through the group's mobile banking applications, according to reports.

The issue affected customers using apps for Lloyds Bank, Bank of Scotland, and Halifax, all of which are part of Lloyds Banking Group. Users reported seeing payments and charges that belonged to other customers rather than their own account information.

The incident represents a significant privacy breach affecting one of the UK's largest banking groups. Lloyds Banking Group serves millions of customers across its three main retail banking brands.

Mobile banking applications have become increasingly important for financial institutions as customers shift away from branch-based banking. The apps typically require multiple layers of security authentication to protect sensitive financial information.

The banking group has not yet provided details about how many customers were affected by the issue or what steps are being taken to prevent similar incidents in the future.
