The threat actor leverages cloud services like Yandex and pCloud for command and control infrastructure, complicating detection and attribution efforts.
A campaign targeting Russian corporate entities, particularly HR, payroll, and administrative departments, has been uncovered. The attack uses realistic decoy documents themed around employee bonuses and financial policies. The malware ecosystem involves a malicious LNK file leading to an implant dubbed DUPERUNNER, which then loads the AdaptixC2 Beacon to connect to the threat actor's infrastructure. The infection chain begins with a spear-phishing ZIP archive containing PDF-themed LNK files. The DUPERUNNER implant, programmed in C++, performs various functions including downloading and opening decoy PDFs, process enumeration, and shellcode injection. The final stage involves the AdaptixC2 Beacon, which communicates with the command-and-control server. The campaign, tracked as UNG0902, uses multiple malicious infrastructures and is believed to be targeting employees of various organizations.
Operation Hanoi Thief is a spear-phishing campaign targeting Vietnamese IT professionals and recruitment teams. It uses malicious ZIP files containing fake resumes and LNK files that execute a pseudo-polyglot payload. This payload deploys a C++ DLL implant named LOTUSHARVEST via DLL sideloading, which steals browser credentials and history. The stolen data is exfiltrated to attacker-controlled servers. The campaign uses anti-analysis techniques and abuses trusted Windows tools to evade detection. While it shares similarities with Chinese-origin campaigns, state sponsorship is not confirmed. The attack primarily affects Vietnam's IT and recruitment sectors, with no known exploits in the wild beyond spear-phishing. The campaign poses a medium severity threat due to its targeted nature and credential theft capabilities. European organizations are not directly targeted but could be at risk if similar tactics spread. Mitigation requires focused user training, monitoring for DLL sideloading, and blocking known indicators of compromise.
