According to its latest quarterly advanced persistent threat threat landscape report, TetrisPhantom is a “highly sophisticated” and persistent threat with no discernible links to known threat actors.This covert operation involved the exploitation of a particular type of secure USB drive, specifically designed for secure data storage and encryption.
“The attacks were extremely targeted and had a quite limited number of victims. Our investigation revealed a high level of sophistication in the malicious tools used in the deployment of the attacks. We believe these attacks have been carried out by a highly skilled and resourceful threat actor interested in espionage activities in sensitive and protected government networks.
As the TetrisPhantom campaign remains active, experts are closely monitoring its progress and anticipate even more sophisticated attacks in the future, she noted.
