PODGORICA, Montenegro (AP) — A rapid deployment team of FBI cyber experts is heading to Montenegro to investigate a massive and coordinated attack on the tiny Balkan nation’s government and its services. The country’s Ministry of Internal Affairs announced the deployment Wednesday, calling it “another confirmation of the excellent cooperation between the United States of America and Montenegro.” Last weekend, Montenegro’s Agency for National Security said the country was “under a hybrid war” blaming the attack squarely on Russia, though without providing evidence. A cybercriminal extortion gang has claimed responsibility for at least part of the attack, infecting a parliamentary office with ransomware known as Cuba. Montenegro has displeased Russia by joining NATO and Western sanctions against Russia.
