KIEV, Dec. 16 – The Finance Ministry and State Treasury Service have lost 3 terabytes of information to a hacker's attack in December, said First Deputy Director of the National Institute for Strategic Studies Oleksandr Vlasiuk.

"Along with damage caused to network equipment, the institutions have lost 3 terabytes of information, according to their estimates. This is a large figure," he said at a roundtable in Kiev on Friday.

He said that in July 2016 cases of trade with customs databases were recorded.
