Loading threat actor…
Silence, also known as Silence Group, Silence (Group-IB), and Whisper Spider, is a Russian-linked threat actor. The group conducts spearphishing operations using malicious document, archive, shortcut, and compiled-help attachments that rely on user execution. It uses PowerShell, JavaScript, VBScript, Windows command-shell activity, and Windows API calls to execute payloads and deploy additional malware. Silence has established persistence through scheduled tasks, Registry-based autorun mechanisms, and Startup-folder artifacts. Its tooling can capture screen activity, modify Registry data, and delete scheduled tasks, command-and-control-delivered files, and logs to reduce forensic visibility. Silence also masquerades malware as legitimate Microsoft Office-related processes.

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.
