Detects instances where a process deletes its own executable or script file within 15 seconds of being launched. This behavior is often associated with self-modifying implants, transient scripts, or malicious artifacts attempting to minimize their footprint on the host system immediately after execution.

Detects the execution of PowerShell with hidden window style attempting to download Node.js related files (e.g., .msi or node.exe) from nodejs.org using common download cmdlets or utilities.

Detects the execution of PowerShell with hidden window style attempting to download Node.js related files (e.g., .msi or node.exe) from nodejs.org using common download cmdlets or utilities.
Detects the creation of files named '.git-checker' within common temporary directories. This behavior is often associated with staging or persistence mechanisms used by malware or malicious scripts to track execution or environment status.
This rule detects the execution of AnyDesk within a 30-minute window of Microsoft Teams activity on the same device. This pattern is indicative of a vishing attack, where a malicious actor lures a victim into installing remote access software during a fake technical support session initiated via Teams.
Detects instances where node.js or npm processes spawn child processes that subsequently perform write operations into Windows startup folders or registry run keys within a one-hour window. This behavior is indicative of a second-stage payload execution and persistence mechanism often leveraged by threat actors.
This rule detects instances where the legitimate remote desktop application AnyDesk (AnyDesk.exe) acts as the parent process to spawn a Windows command shell (cmd.exe) or execute a batch script (.bat). This behavior is often indicative of unauthorized remote access or the execution of malicious payloads by adversaries leveraging remote support tools.
Detects the modification of InProcServer32 registry keys within the user's Classes/CLSID hive to point to a file located in the AppData directory. This pattern is commonly used for COM hijacking to achieve persistence or execute arbitrary code under the user's context.
This rule detects network connections or DNS requests to domains specifically structured to impersonate MFA registration, passkey setup, or SSO login pages. These domain patterns are commonly associated with phishing campaigns intended to harvest credentials, session tokens, or bypass multi-factor authentication (AiTM phishing).
Detects the 'sharedLoad.min.js' loader script associated with the malicious 'indexed-btree' npm package family. This script utilizes X25519 ECDH for key exchange and AES-256 decryption to retrieve and execute a second-stage payload hosted on a Sepolia smart contract.
Detects the loading of wkspbroker.exe or radcui.dll modules from the Microsoft RemoteApp Gateway directory located within the user's AppData path. This behavior may indicate an attempt to utilize or manipulate Remote Desktop components from a non-standard or user-writable location.
Detects Node.js processes executing command lines containing known malicious indicators or accessing specific suspicious JavaScript files (e.g., sharedLoad.min.js) associated with malicious loaders or hardcoded cryptographic keys.
Detects the execution of AnyDesk shortly after a Microsoft Teams meeting or call initiation on the same host. This pattern is commonly observed in social engineering attacks where an adversary convinces a user to use remote access software during a live support or phishing call.
This rule detects a multi-stage attack chain targeting a single user within a 2-hour window. It identifies the combination of email bombing (a distraction technique), an incoming external or anonymous Teams call (social engineering channel), and the installation of common remote access tools (e.g., AnyDesk, TeamViewer) on the same host.
This rule detects the use of specific tools associated with credential dumping and memory forensics, including Dokan driver installations for file system mounting, the use of DumpIt for creating memory dumps, and the subsequent analysis of these dumps using MemProcFS to access sensitive process memory information such as LSASS minidumps.
This rule monitors for file and process creation events associated with known FeralWolf threat actor malware, including MQTTDoor, MatrixDoor, RDPSocksProxy, GenieLocker ransomware, fscan, and tools leveraging CVE-2026-31431.
Detects the abuse of the forfiles.exe utility to indirectly execute command-line interpreters such as cmd.exe, powershell.exe, or other common LOLBins. Adversaries use this technique to bypass security controls that monitor or restrict direct execution of these interpreters.
Detects the invocation of Windows Subsystem for Linux (WSL) binaries (wsl.exe or wslconfig.exe) using command-line arguments that enable arbitrary command execution, such as -e, --exec, or shell interpreters (bash -c, sh -c), or web-based retrieval tools like curl/wget. This technique is often used to execute commands or download payloads within a Linux environment on Windows, potentially bypassing security controls focused on native Windows processes.
Detects instances where AI coding assistants or tools (e.g., Claude, Copilot, Gemini) invoke git.exe to clone or fetch repositories from non-standard (non-GitHub) hosts, followed by a checkout operation within a short timeframe. This behavior may indicate an attacker using automated tools to stage or exfiltrate sensitive code repositories to unauthorized infrastructure.
