The Ministry of Defence is investigating claims that Russian hackers have stolen hundreds of sensitive military documents and published them on the dark web.
The files hold details of eight RAF and Royal Navy bases as well as Ministry of Defence staff names and emails, The Mail On Sunday reported.
Cybercriminals accessed the cache of files by hacking a maintenance and construction contractor called Dodd Group, the newspaper said.
A Ministry of Defence (MoD) spokesperson said: âWe take a robust and proactive approach to cyber threats that could pose risks to national interests.
âWe are actively investigating claims that information relating to the MoD has been published on the Dark Web.
âTo safeguard sensitive operational information, we will not comment any further on the details.â
The Dodd Group has been approached for comment.
Leaked documents reportedly hold information about a number of sensitive RAF and Navy bases, including RAF Lakenheath, in Suffolk, where the US Air Forceâs F-35 jets are based.
The hack follows a series of high profile data breaches at the MoD.
Personal data of service personnel and veterans, including names, bank details and some addresses, was in the payroll system which was accessed in the large-scale hack, revealed last year.
Up to 272,000 service personnel may have been affected.
The same year, the Government covertly set up the Afghanistan Response Route for people in the country whose details were leaked âin errorâ by a defence official in February 2022.
