According to the hacker group that leaked the documents, the UK used the Integrity Initiative to meddle in the domestic affairs of other European states and to wage an information war against Russia.
The Integrity Initiative project has admitted in an official statement that it was recently hacked by unknown hackers and that the documents leaked by Anonymous on 23 November 2018 at least partially belong to them.
“It is of course a matter of deep regret that Integrity Initiative documents have been stolen and posted online,” the statement said.
