Severity

High

Analysis Summary

Cyber espionage actors, aka APT32 (OceanLotus Group), are carrying out intrusions into private sector companies across multiple industries and have also targeted foreign governments, dissidents, and journalists. APT32 leverages a unique suite of fully-featured malware, in conjunction with commercially available tools, to conduct targeted operations that are aligned with Vietnamese state interests. In their current campaign, APT32 has leveraged files that employ social engineering methods to entice the victim into enabling macros. Upon execution, the initialized file downloads multiple malicious payloads from remote servers. APT32 actors continue to deliver malicious attachments via spear-phishing emails. APT32 actors designed multilingual lure documents which were tailored to specific victims. Although the files had “.DRV” file extensions, the recovered phishing lures were web page archives that contained text and images.
