Twisted Panda: Chinese APT espionage operation against Russia

Check Point Research (CPR) details a targeted campaign that has been using sanctions-related baits to attack Russian defense institutes, part of the Rostec Corporation.
The investigation shows that this campaign is part of a larger Chinese espionage operation that has been ongoing against Russian-related entities for several months.
CPR researchers estimate with high confidence that the campaign has been carried out by an experienced and sophisticated Chinese nation-state APT.
