The home addresses of some Metropolitan Police officers may have been compromised by computer hackers, according to reports. Commissioner Sir Mark Rowley has assured the force’s 47,000 officers and support workers that their personal details were not affected by the IT breach at a company responsible for producing warrant cards and passes. However, an initial survey of data held by Stockport-based Digital ID has revealed that hackers may have gained access to home addresses of some Met workers. The breach occurred after new warrant cards and passes were produced as part of a security improvement scheme called Operation Fortress. Many officers expressed frustration that news of the breach was posted on an internal intranet over a Bank Holiday weekend instead of being sent directly to them via email. The National Crime Agency is leading the investigation into the incident, with support from the National Cyber Security Centre. The Met is currently conducting a review of all data held by the firm. Other police forces, government departments, and major companies also used Digital ID, although it is believed they only used the firm’s printing equipment rather than sharing information.
