A recent glitch in the banking apps of Lloyds, Halifax, and Bank of Scotland led to the exposure of sensitive customer information. According to NS3.AI, the issue allowed some users to view other customers' transactions and account details for approximately 20 minutes. Reports indicate that exposed information included National Insurance numbers and benefit payment details. The problem has since been resolved, and an investigation is currently underway to determine the extent of the impact. The exact number of affected customers has not yet been disclosed.
