Higaisa is an advanced persistent threat group associated with targeted intrusions. It has used malicious email attachments to induce victims to execute LNK files, followed by VBScript and Windows Command Shell execution. Higaisa has established persistence through Windows Scheduled Tasks, including task-based execution of a dropped payload. Its post-compromise tradecraft includes process identification, system-information discovery using host identifiers, system-time discovery, and network-configuration discovery using ipconfig. Higaisa has also used hidden windows to reduce user visibility, encrypted command-and-control traffic with AES-128, and exfiltrated collected data over its command-and-control channel.

Royal Road is a tool that generates RTF files that exploit the Microsoft Office Equation Editor vulnerabilities (CVE-2017-11882, CVE-2018-0798, CVE-2018-0802).
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.
