It noted that at present there is no evidence of the campaign having links "with a nation-state sponsored attack".

According to the report, the targets were mainly countries in Eastern Europe, former USSR Republics, and Central Asia.

"The main objective of the attackers was to gather sensitive documents from the compromised organizations, which included geopolitical intelligence, credentials to access classified computer systems, and data from personal mobile devices and network equipment," Kaspersky said.

Regarding the perpetrators, the report said that currently there is no evidence of links "with a nation-state sponsored attack".

It noted that the information stolen by the attackers is obviously of the highest level and includes geopolitical data which can be used by nation states.

"Such information could be traded in the underground and sold to the highest bidder, which can be of course, anywhere," it added.

While the "exploits appear to have been created by Chinese hackers", the Rocra malware modules have been created by Russian-speaking operatives, the report said.
