 Ukrainian government agencies and critical infrastructure have long been targets for Russian cyber attacks. Intelligence sharing between Ukraine and the US has helped defend American networks in turn. Now, a federal grand jury in Maryland has returned an indictment against a 22 year old Russian hacker named Amin Timovich Stigl. The US government alleges he was involved in launching destructive cyber attacks at Ukrainian government agencies with no military or defense role. The attacks permanently wiped away important government data.
