Some personal information in a payroll system used by Britain's defense department has been accessed in a data breach, the BBC reported on Monday.
The system was managed by an external contractor and no operational Ministry of Defence data was obtained, the broadcaster said, adding that the department took the system off-line immediately.
Information like names and bank details of current and some former members of the Royal Navy, Army and Air Force was compromised, according to the report.
The Ministry of Defense did not immediately respond to a Reuters' request for comment outside working hours.
MPs could be informed about the development in the Commons on Tuesday, the report added.
