Detects attempts to disable or modify Windows Defender security features, such as Real-time Monitoring, Tamper Protection, or adding unauthorized exclusion paths via PowerShell cmdlets or direct registry modifications.
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.

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.

Detects instances where FortiClient EMS management daemon processes (FCMDaemon.exe, FortiClient_Server.exe, or FCMWebServer.exe) spawn suspicious child processes often associated with living-off-the-land techniques, such as command shells, scripting interpreters, or system administrative utilities.
Detects attempts to modify, disable, or query Microsoft Defender configuration settings or status using legitimate Windows management tools (PowerShell/WMI) by processes other than authorized Defender executables (MsMpEng.exe, MpCmdRun.exe).
Detects the use of PowerShell to modify Windows Defender exclusions by adding a path or process located in user-controlled directories (Downloads, Temp, AppData). This behavior is characteristic of adversaries attempting to suppress security alerts for malicious binaries masquerading as legitimate software.
Detects execution of netcat with the "-e" flag followed by common shells. This could be a sign of a potential reverse shell setup.
Detects instances where the Steam service (steamservice.exe) is executing suspicious child processes such as command interpreters or binaries located in unusual paths like Temp, Downloads, or AppData, often indicating an attempt to hide malicious activity under a trusted process.
Detects the creation of multiple suspicious scheduled tasks using schtasks.exe initiated by scripting engines (wscript.exe, cscript.exe). The rule filters for specific task names associated with known malicious patterns and XML definition files located in a specific directory path, identifying potential automated persistence or malware installation behavior.
