Hunts network, HTTP, and email-URL telemetry for known ARToken infrastructure (operator backend IPs and phishing/panel domains). Bounded to a 30-day lookback and tiers matches by confidence: domain hits are high-confidence (attacker-registered infrastructure), while IP hits are medium-confidence since the IPs sit on shared DigitalOcean hosting that can be reassigned to unrelated tenants once ARToken's infrastructure is taken down. Empty/unparsed indicator fields are excluded to avoid spurious matches in the HTTP event parsing branch. No known file hashes are associated with this intel.
Detects potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.
Detects potential ClickFix-style social engineering attacks where a victim is prompted to execute an encoded PowerShell command (often via copy-paste into a terminal). The rule specifically monitors PowerShell processes initiated by shell environments (explorer.exe, cmd.exe, or WindowsTerminal.exe) that execute encoded, hidden scripts to perform multiple suspicious network requests for files (e.g., .zip, .enc, .bin) from non-standard domains.
This rule monitors DeviceNetworkEvents for any outbound network connections to a specific list of known malicious domains. The rule identifies potential command and control (C2) communication by matching remote URLs against a hardcoded set of domains associated with known threats.

Detects the creation or modification of a Windows service named 'ProcAuditManager' via registry keys or command-line utilities. This pattern is indicative of potential persistence mechanisms or service manipulation for malicious purposes.

This rule detects activity associated with the exploitation of PaperCut vulnerabilities. It looks for connections to known malicious IP addresses, the presence of specific credential harvesting tools, reconnaissance commands (whoami, tasklist) executed by the PaperCut application (pc-app.exe), suspicious PowerShell downloads of AnyDesk, and unauthorized access to PaperCut configuration files or log files containing known exploit strings.
Detects uncommon or suspicious child processes spawning from a WSL process. This could indicate an attempt to evade parent/child relationship detections or persistence attempts via cron using WSL.
This rule detects the execution of PowerShell from a WScript or CScript parent process where the PowerShell script also performs suspicious actions such as reading environment variables (specifically those following a 'Kv\d+' pattern) and accessing files using 'IO.File::ReadAllText'. This behavior is indicative of malicious scripts, such as those used by specific malware or post-exploitation tools, attempting to retrieve configuration data or credentials stored in environment variables.
Detects the execution of PowerShell via script interpreters (wscript.exe, cscript.exe) or terminal hosts (conhost.exe) where the command line contains specific environment variable lookups and obfuscated string identifiers. This pattern is commonly associated with malware or malicious payloads attempting to execute PowerShell commands indirectly to evade detection.
Detects the execution of PowerShell with suspicious command-line arguments (obfuscation, hidden windows, or encoded commands) directly spawned from explorer.exe. This activity is frequently associated with malicious scripts or payloads executing in the context of user activities to evade detection.
Detects malicious PowerShell scripts that perform reflective loading of .NET DLLs into memory. The rule identifies patterns associated with the 'ClickFix' or 'StealC' loaders, specifically looking for combinations of Assembly.Load, GZip decompression, and hardcoded AES encryption keys/IVs frequently used by these campaigns.
Detects unauthorized access to sensitive browser files, specifically 'Login Data' (passwords) and 'Cookies', by processes other than authorized browser binaries (Chrome or Edge). This is a common indicator of credential harvesting or session hijacking attempts by malware or malicious actors.
Detects the presence of the known vulnerable gdrv.sys driver on disk. This driver is frequently utilized in Bring Your Own Vulnerable Driver (BYOVD) attacks to gain kernel-mode access, which is often leveraged to disable endpoint security products or escalate privileges.
Detects the execution of MeshAgent or mvtcs (MeshCentral) binaries, which are commonly used for legitimate remote management but can also be used as unauthorized remote access tools by adversaries.
Detects WriteProcessMemory or CreateRemoteThread operations targeting csc.exe or chrome.exe. This activity is often associated with process injection techniques used to execute code within the context of a legitimate or compiler-related process.

Detects the use of the native Windows utility cipher.exe with the /w flag executed from the command prompt. The /w switch instructs cipher to remove data from available unused disk space, which is a technique often used by threat actors to hinder forensic recovery of deleted files.
Detects the use of wevtutil.exe to clear the Microsoft-Windows-Defender/Operational event log, which is often done by adversaries to remove evidence of security software activity or detection.
