The Chair of the Treasury Committee has contacted Lloyds Banking Group following a technical malfunction last week that resulted in some customers viewing details from other people’s accounts in the bank’s app.
Last week, reports emerged that customers using Lloyds’ digital services had experienced issues with account visibility, with some users able to access information belonging to others.
In her correspondence, Dame Meg Hillier described the event as an “alarming breach of confidentiality” and called for “transparency” about the nature and extent of the problem.
In a statement to Retail Banker International, the bank said: “Some customers using our app may have briefly seen transactions that weren’t theirs due to an internal IT change.
“We’re very sorry this happened. No action is needed from customers and there was no issue with account security.”
The bank added: “We’ve identified those affected and will contact them to provide further information. We will of course respond to Dame Meg’s letter as soon as possible.”
The committee’s letter requests a detailed summary of the incident covering which platforms and brands were implicated and outlining the sequence of events in the bank’s response.
Additional queries include specific details about what kind of information was disclosed, whether it was limited to transaction details or included sensitive personal data such as National Insurance numbers, and if those affected can be identified and informed.
Lloyds has also been asked to provide figures distinguishing between those who accessed others’ information and those whose details were exposed, as well as steps being taken to address possible misuse of this data.
The committee is seeking information on any compensation paid to date, plans for compensating individuals who may not yet be aware of their data was accessed, and when authorities such as the Financial Conduct Authority and Information Commissioner were notified.
Further briefing will be required in one month, including any new findings and an early assessment of whether the breach has caused financial crime.
A comprehensive update is expected within six months, including a full explanation of how the incident occurred and what measures have been put in place to prevent similar events.
“Treasury Committee seeks answers on Lloyd’s Bank data breach” was originally created and published by Retail Banker International, a GlobalData owned brand.
