Detects the execution of PowerShell with suspicious command-line arguments (e.g., encoded commands, hidden windows) initiated by mshta.exe, excluding instances where a .ps1 script file is involved. This pattern often indicates attempts to bypass execution policy or run obfuscated payloads in memory, which is a common behavior of malicious HTA files.
This rule detects potentially malicious command-line activity involving powershell.exe or mshta.exe that is initiated by a web browser process (chrome.exe, msedge.exe, firefox.exe, or iexplore.exe). It monitors for indicators such as encoded commands, usage of Invoke-Expression, download cradles, hidden window flags, and specific known IOCs, correlating these events with recent browser activity to identify potential drive-by download or browser-based exploitation attempts.
This rule detects the use of 'mshta.exe' to execute a file from a remote location by inspecting the command line for 'http' protocols and a specific suspicious domain. Adversaries often abuse mshta.exe to proxy the execution of malicious HTML Application (HTA) files or scripts to bypass security controls.
Detects modifications or creation of InprocServer32 COM registry keys by suspicious processes like mshta.exe or powershell.exe, which is indicative of COM Hijacking for persistence or privilege escalation.

Detects suspicious execution of PowerShell or Mshta spawned from Explorer.exe. It looks for specific malicious indicators including references to known malicious domains, PowerShell encoding flags, hidden window arguments, or Mshta HTTP requests, which are common patterns for fileless malware or dropper execution.

Detects instances where Faronics Core related processes (FaronicsCore.exe, NCService.exe, ScriptRunner.exe) spawn common system utilities (curl.exe, mshta.exe, msiexec.exe) often used for downloading or executing payloads. This pattern may indicate the abuse of legitimate management software to facilitate unauthorized activity or second-stage payload delivery.

Detects the execution of LOLBins (PowerShell, mshta, cmd, wscript) directly spawned from common web browsers (explorer, chrome, edge, firefox) with command-line arguments indicative of malicious activity, such as base64-encoded commands, hidden window styles, or remote script download and execution.
