AlienVault OTX Malware

The Genians Security Center (GSC) detected an APT (Advanced Persistent Threat) campaign targeting users of Facebook, email, and Telegram in Korea between March and April 2025. The threat actor explored reconnaissance and selected attack targets through two Facebook accounts.

The threat detailed is an Advanced Persistent Threat (APT) campaign attributed to the Kimsuky group, a known North Korean state-sponsored actor. This campaign, detected by the Genians Security Center (GSC), targeted users primarily in South Korea between March and April 2025. The attack vector leveraged social media and communication platforms including Facebook, email, and Telegram to conduct reconnaissance and select targets. The adversary used two Facebook accounts for initial reconnaissance, indicating a targeted approach rather than broad indiscriminate attacks. The campaign is characterized by a 'Triple Combo' threat methodology, involving multiple stages and tools to achieve persistence and data exfiltration.

Technical analysis reveals the use of various malware components, including DLL files protected by VMProtect, PowerShell scripts, and shellcode execution techniques. The campaign employs obfuscation and evasion tactics such as code injection (T1055), command and scripting interpreter abuse (T1059), and persistence mechanisms (T1547). The threat actor also uses social engineering (T1566) and user execution (T1204) to trick victims into executing malicious payloads. Indicators of compromise include numerous file hashes (MD5, SHA1, SHA256) and domains primarily associated with Korean infrastructure (e.g., *.n-e.kr, *.o-r.kr, *.p-e.kr) and some international domains (e.g., download.uberlingen.com).

The campaign’s focus on Facebook, email, and Telegram suggests exploitation of widely used communication channels to infiltrate target networks. The use of multiple platforms increases the attack surface and complicates detection. The lack of known exploits in the wild indicates the campaign is currently limited in scope or newly discovered. The campaign’s medium severity rating reflects a moderate but credible threat level, given the sophistication and persistence of the Kimsuky group. The attack techniques align with MITRE ATT&CK tactics such as reconnaissance, execution, persistence, privilege escalation, defense evasion, credential access, and exfiltration.

Overall, this APT campaign demonstrates a multi-faceted, targeted attack leveraging social engineering and advanced malware to compromise selected users and organizations, primarily in South Korea but with potential implications for other regions.
