The Kimsuky hacking group is behind a new social engineering attack, using fictitious Facebook accounts to target individuals via Messenger and deliver malware. The campaign impersonates a legitimate individual to trick activists in the North Korean human rights and anti-North Korea sectors. This approach aims to avoid detection and may be targeting specific individuals in Japan and South Korea. The campaign overlaps with prior Kimsuky activity, and it is noted that covert attacks via social media are increasingly occurring. Follow for more exclusive content.
Key takeaways from the meeting notes on the North Korea-linked Kimsuky hacking group and their social engineering attack utilizing fictitious Facebook accounts to deliver malware via Messenger include:
– The attack campaign targets activists in the North Korean human rights and anti-North Korea sectors, leveraging a multi-stage social media approach to trick victims into opening seemingly private documents hosted on OneDrive.
– The use of uncommon MSC files and techniques designed to mask the file as an innocuous Word document demonstrate Kimsuky’s efforts to avoid detection and increase the likelihood of successful infection.
– The attack sequence involves establishing a connection with an adversary-controlled server, activating the exfiltration of gathered information to a command-and-control (C2) server, and harvesting IP addresses, User-Agent strings, and timestamp information from the HTTP requests.
– The tactics, techniques, and procedures (TTPs) adopted in the campaign overlap with prior Kimsuky activity, reinforcing the group’s evolution and persistent threat in disseminating malware.
Furthermore, the discussion highlighted the significance of detecting personalized threats at an early stage due to their one-on-one, personalized nature and the challenges associated with their detection through conventional security monitoring methods. Additionally, the meeting noted that covert attacks via social media are occurring, pointing to the importance of remaining vigilant against such threats.
