Cinnamon Tempest, also known as Emperor Dragonfly, BRONZE STARLIGHT, DEV-0401, Highground, and SLIME34, is a China-aligned intrusion cluster associated with espionage-focused operations that have also employed ransomware. The group has targeted Southeast Asian gambling organizations, including activity affecting the Philippines. It has used trojanized software and DLL search-order hijacking to side-load malicious DLLs through legitimate signed executables, delivering HUI Loader variants and Cobalt Strike Beacon payloads. Cinnamon Tempest has exploited public-facing applications, executed PowerShell, used DNS for command-and-control activity, and created Windows services for persistence. It has also used NPS tunneling tooling alongside Cobalt Strike and Meterpreter for post-compromise network pivoting. The cluster has been linked to LockBit affiliate activity and has deployed ransomware through batch scripts distributed by Group Policy, but available assessments characterize espionage rather than financial gain as its primary objective.

Cynet has detected active exploitations of the Log4Shell vulnerability on VMware Horizon Servers by different threat actors who deployed Cobalt Strike beacons, Cryptominers, and fileless reverse shells.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
