Bank of Scotland customers see strangers' transactions in app glitch

Users took to X, this morning claiming they were seeing payments and account details that did not belong to them, with some saying the transactions dated back weeks.

One customer wrote: “Serious problems with your mobile app today. I am getting other people’s bank account spending appearing on my account and then disappearing! I can’t access your fraud service to inform anyone. Sort it out! I have taken pictures to prove it.”

@faisalislam My wife woke up this morning to someone else’s details and transactions in her Bank of Scotland app. Just seen someone with Lloyds saying the same. Seems to be widespread

Another user who spoke to the Glasgow Times said: “I logged in and seen a payment I didnt recognised and I refreshed it and it was gone.

Hundreds of payments kept appearing and dissapwaring and it was for London transport and Pizza Express. Why are transactions coming out to London when I live in Scotland?

"I phoned customer services and its queues for 50 minute. I panicked, froze my card but I cant get through to any body.”

Another user posted on X: “I’ve logged out and logged back in and different payments are showing up going back to February now including nearly £4000 to Ferrars Junior School which is in Luton and I stay in Scotland.”

Another added: “I am getting this too. Log and log back in is awful advice.”

Concerns quickly escalated, with customers questioning whether their personal data was secure if they were able to view what appeared to be other people’s transactions and account details.

In response to complaints on X, Bank of Scotland said it was investigating the issue and suggested it may be a technical problem.

A Bank of Scotland spokesperson said: “We're aware that some customers are experiencing difficulties logging into our app and online banking. We're sorry about this. Our teams are aware and working hard to fix it."

Bank of Scotland is part of Lloyds Banking Group, which also includes Halifax and Lloyds Bank.

We're aware that some customers are experiencing difficulties logging into our app and online banking. We're sorry about this. Our teams are aware and working hard to fix it.

It is not yet clear how many customers have been affected or how long the issue is expected to last.

Simarjot Singh Judge, Managing Partner at Judge Law, said: “If banking customers were able to see the transactions or financial details of other account holders, even briefly, that could potentially amount to a serious personal data breach.

Under UK GDPR and the Data Protection Act 2018, banks have a strict legal duty to ensure that customers’ personal and financial information is kept secure and only accessible to the correct individual. Financial transaction data is particularly sensitive, so the standards expected of banks are extremely high.

If people were shown details such as wages, payments or account activity belonging to other customers, regulators will likely want to understand how the breach occurred and whether the bank’s safeguards were adequate.

In situations like this, affected customers may be entitled to raise a complaint with the Information Commissioner’s Office, and in some cases individuals may also have the right to seek compensation if the breach caused distress, financial loss or misuse of their personal data.

Even if the issue was quickly resolved, incidents involving the exposure of banking data will always be taken very seriously from a legal and regulatory perspective.”
