Detects the ClickFix infection chain where a web browser process spawns PowerShell to execute obfuscated ScriptBlock content. This activity is correlated with network connections to identified ErrTraffic C2 infrastructure (/api/index.php?a=ctx) used for distributing various malware payloads including Vidar, Stealc, and others.
Detects the 'procq' process establishing network connections to common Monero (XMR) mining pool ports. This behavior is indicative of a cryptominer deployment, specifically associated with the Langflow cryptominer campaign related to CVE-2026-33017.
Detects instances where browser processes (Chrome, Edge, Firefox) directly spawn PowerShell or MSHTA. This is a behavioral indicator of the 'ClickFix' social engineering technique, where victims are tricked into copying and pasting malicious commands into a terminal, often presented as 'fixes' for fake browser error messages or verification prompts.
Detects the behavioral pattern of Vidar Stealer where it launches Chrome, Edge, or Brave browsers with specific command-line arguments ('--no-first-run', '--disable-gpu', 'about:blank') from a non-browser parent process. This technique is often used by Vidar to facilitate browser data theft while evading static analysis by using process hollowing or similar injection techniques against the spawned browser process.
Detects the Meow RAT malware attempting to identify the system locale and keyboard settings on macOS. This behavior is used by the malware to fingerprint the target environment and specifically avoid infection if the system is identified as belonging to CIS (Commonwealth of Independent States) regions.
Detects the use of osascript to spawn fake macOS system dialogs that mimic legitimate 'System Preferences' prompts to harvest user login passwords. This activity often involves AppleScript dialog commands combined with dscl authonly checks to validate the stolen credentials.
Detects the presence of Remcos RAT by correlating a specific mutex (Remcos_Mutex_Inj) indicative of active malicious processes with an outbound network connection to a known command-and-control (C2) IP address (62.102.148.212) on port 37393. This combination is characteristic of Remcos RAT operations used for unauthorized audio and webcam surveillance.
Detects a suspicious pattern where a highly privileged on-premises synchronized user account signs into Azure Active Directory (Entra ID) and immediately performs sensitive administrative actions (role assignment or OAuth application consent grant) within a 30-minute window. This behavior is indicative of credential abuse by the Storm-2372 actor to escalate privileges within a tenant.
Detects the execution of a Nuitka-compiled Python RAT (chost.exe) associated with the PostCSS typosquatting campaign. The rule identifies this malicious binary when spawned by wscript.exe, powershell.exe, or node.exe from a location outside of C:\Windows\, followed by network communication to known campaign-associated C2 infrastructure.
Detects the execution of OXLOADER (aBsvwbdas.exe) which drops a maliciously crafted .ocx file (a copy of dui70.dll) into the %TEMP% directory. This behavior is indicative of module stomping to facilitate the in-memory execution of CASTLESTEALER via techniques like DonutLoader and RunPE.
