American spy left UK military files online while working from home in shocking security breach

  • A US spy left British military secrets online so that he could work from home
  • Adam Sitzes left details of UK arms deals and military equipment on Trello
  • Mr Sitzes is likely to face immediate investigation after the intelligence breach 

A US spy left British military secrets online after he uploaded them so that he could work from home, it has been reported.

Adam Sitzes included details of the RAF’s £125million Typhoon jets, exposed arms deals and named top officials and counter-terror staff in the UK, Nato and Ukraine.

It is feared Mr Sitzes, who is a US Air Force worker in his 40s, forgot about the unencrypted dossier after he uploaded it to file-sharing website Trello in 2020 and gave it public access so he could view it on any device while working from home.

A source told The Sun newspaper: ‘He’s likely to face an immediate investigation.’ Whitehall was informed of the breach and all files have since been removed.

Ex-CIA terror expert Aki Peritz said: ‘Making sensitive information available in one place, on a specific topic, with a shiny red bow tying it all together makes it easy for an adversary to exploit. It’s so stupid.’

It comes as the Daily Mail revealed the UK’s civil service jobs website is still advertising 64 vacancies involving partial or total working from home which include sensitive positions with GCHQ, the Government’s intelligence and security organisation, and with counter-terrorism at the Home Office.

A security expert warned of the ‘absolutely enormous’ risks that could be posed by civil servants in these areas working from home, especially at a time of ‘grave international danger’ given Russia’s invasion of Ukraine.
