A North Korean threat actor has been behind a new espionage campaign targeting high-profile government officials in South Korea. Cybersecurity firm Malwarebytes attributed the activity to a threat actor tracked as Kimsuky. The actor has a track record of singling out South Korean entities while expanding their victimology to the U.S., Russia, and various nations in Europe. The threat actor calls themselves Thallium in the malware source code, which is the moniker assigned by Microsoft based on its tradition of naming nation-state hacking groups after chemical elements.
