Detects suspicious process execution patterns associated with RMMCRAT, where the Windows SmartScreen process (smartscreen.exe) spawns cmd.exe, which subsequently launches PowerShell with specific parameters for piped input/output. This behavior is characteristic of malicious code injection and command-and-control activity.

Detects parent process ID (PPID) spoofing associated with RMMCRAT and other HVNC malware, where an injected process (e.g., smartscreen.exe) spawns child processes while spoofing explorer.exe as the parent. The rule monitors for a mismatch between the reported parent (explorer.exe) and the actual creator (smartscreen.exe) and focuses on burst activity of common shell and browser processes.

Detects indicators of RMMCRAT malware installation, which masquerades as JivaChat software. The rule identifies suspicious process execution (e.g., rmm.exe), specific file artifacts created in ProgramData, and persistence mechanisms including Windows service registration, 'Load' registry value abuse, and a unique COM CLSID hijack. The logic enforces corroboration across different signal types (process, file, registry) or triggers on the unique CLSID.

Detects PavokwiLoader behavior where a potentially malicious process spawns a browser or system process (e.g., smartscreen.exe) in a suspended state, followed by cross-process memory allocation and writing, and subsequent thread hijacking or execution resumption, indicating a process hollowing injection technique.
