North Korean State Actors Deploying Novel Malware to Spy on Journalists
New analysis has attributed a spear-phishing campaign targeting journalists covering North Korea to APT37/Ricochet Chollimia, a state-backed group linked to the Democratic People's Republic of Korea (DPRK). Notably, researchers said the group is deploying a novel malware strain called Goldbackdoor, a variation of Bluelight malware previously attributed to APT37.
According to a report from researchers at Stairwell, multiple phishing emails were sent to NK News on Mar. 18 that appeared to be from the personal email address of the previously compromised former head of of the South Korean National Intelligence Service, and contained Goldbackdoor malware. NK News handed over the information to Stairwell for further investigation, the cybersecurity firm said.
