The U.S. government issued a cybersecurity advisory about North Korean threat actors using spear-phishing campaigns to gather intelligence. They exploit weak DMARC policies to send spoofed emails, targeting foreign policy experts. The group, known as Kimsuky, engages targets in prolonged, benign conversations to build trust and uses fake email addresses to appear legitimate. Organizations are advised to update their DMARC policies for protection.
The meeting notes provide a detailed overview of the recent cybersecurity advisory warning from the U.S. government about North Korean threat actors’ spear-phishing campaigns. The advisory, jointly released by the NSA, FBI, and the Department of State, highlights the use of improperly configured DNS DMARC policies to facilitate these campaigns. The threat actors, identified as the Kimsuky group, have been targeting foreign policy experts by impersonating legitimate personas and engaging in extended benign conversations to build trust before requesting opinions on sensitive topics. It is noted that the threat actors rarely use malware or credential harvesting directly, instead relying on social engineering tactics to obtain information.
The notes also emphasize that organizations are recommended to update their DMARC policies to treat suspicious or failing email messages as spam and receive aggregate feedback reports to enhance their email security. The article provides valuable insight into the evolving tactics of threat actors and serves as a reminder for organizations to strengthen their cybersecurity measures.
