The European Union sanctioned four Russian domestic intelligence agency hackers including two military officers who participated in what researchers have described as “hack and leak” operations against Western governments.

The two officers are part of a Federal Security Service hacking group known as Callisto Group and Coldriver and formerly tracked by Microsoft as Seaborgium.

The U.K. government in December accused the group of running a decade-long spear-phishing campaign against lawmakers in multiple political parties and leaking classified trade documents published ahead of Britain’s 2019 election. The two officers, Ruslan Peretyatko and Andrey Korinets, already face sanctions from the British and U.S. governments and a criminal indictment in the United States (see: UK and US Accuse Russian FSB of ‘Hack and Leak’ Operation).
