Kimsuky, a North Korea-linked threat actor, has been observed utilizing Compiled HTML Help (CHM) files to distribute malware, targeting entities in South Korea, North America, Asia, and Europe. The cybersecurity firm Rapid7 has attributed this activity to Kimsuky with moderate confidence. The group’s tactics include deploying an Endoor backdoor malware and employing generative artificial intelligence. Ongoing cyber attacks have prompted a UN probe into suspected activities by North Korean nation-state actors.
Key takeaways from the meeting notes:
– Threat actor Kimsuky (aka Black Banshee, Emerald Sleet, or Springtail) has been observed shifting its tactics to leverage Compiled HTML Help (CHM) files as vectors to deliver malware.
– The cybersecurity firm Rapid7 has attributed the activity to Kimsuky with moderate confidence, citing similar tradecraft observed in the past.
– Kimsuky has been targeting entities located in South Korea, North America, Asia, and Europe, with ongoing and evolving attacks, primarily targeting organizations in South Korea.
– Kimsuky is actively using and refining its techniques and tactics, and has shown interest in using generative artificial intelligence, including large language models, potentially for coding or writing phishing emails.
– Symantec revealed that the Kimsuky actors are distributing malware impersonating an application from a legitimate Korean public entity, installing an Endoor backdoor malware upon compromise.
– Kimsuky has been observed using ChatGPT, and has been linked to cyber attacks carrying out by North Korean nation-state actors, including the Lazarus Group and its subordinate elements, Andariel and BlueNoroff.
These takeaways provide a clear understanding of the evolving tactics and targets of the Kimsuky threat actor, as well as its potential use of advanced technologies such as generative artificial intelligence.
