Phone numbers and other personal details of senior ministers from Britain’s Conservative party were made public by an app security flaw over the weekend.
The app malfunction also leaked details of top Brexiteers Michael Gove and Boris Johnson, who, like their colleagues, received nuisance calls after their profiles were accessed on the official mobile application for the annual party conference.
The security breach saw members of the public able to enter the profiles using just the politicians’ email addresses — easily available online — to view and edit the data stored within.
Former foreign secretary Johnson had his profile picture briefly swapped for pornography and his job title changed to a profane insult, according to several Twitter users.
Meanwhile, Environment Secretary Gove’s picture was changed to one of media tycoon Rupert Murdoch, his former employer when he was a journalist.
A Conservative party spokesperson apologised for the breach, saying the technical issue had “been resolved and the app is now functioning securely”.
Britain’s data watchdog, the Information Commissioner’s Office (ICO), said it was investigating the data breach related to the app, which was developed by an Australian firm called Crown Comms.
The opposition Labour Party has already tried to cash in on the blunder, saying it showed the ruling party could not be trusted in matters of security.
“They can’t even build a conference app that keeps the data of their members, MPs and others attending safe and secure,” said shadow cabinet office minister Jon Trickett.
The breach is the latest embarrassment for Prime Minister Theresa May’s embattled party, whose yearly gathering begins on Sunday in the city of Birmingham in central England.
Last year’s conference was peppered with mishaps, with May’s attempt to move past Brexit splits marred by a protest, a collapsing set and a coughing fit.
