Detects anomalous, chained execution patterns initiated by AI agents integrated with Model Context Protocol (MCP) servers. The rule identifies a multi-stage sequence involving the invocation of browser automation tools followed by shell execution and subsequent outbound network activity, potentially indicating an AI-driven attack chaining filesystem, shell, or cloud-API access in an unauthorized manner.

Detects instances where AI-assisted development tools (such as Claude, Codex, Copilot, or Gemini) initiate command-line processes (e.g., shells, interpreters, or network utilities) with arguments indicative of credential access, reconnaissance, or sensitive file interactions.
This rule detects network connections from internal devices to a list of known malicious IP addresses associated with command-and-control (C2) infrastructure. It monitors for outbound traffic across all monitored network events on endpoints.
This rule monitors for outbound TCP and HTTP traffic to a known malicious infrastructure hosting a fake or compromised 'Corp MDM' (Mobile Device Management) admin panel, which serves as a Command and Control (C2) channel for spyware.
Detects anomalous post-exploitation behavior associated with SectopRAT, where a suspicious process (e.g., ReportDump.exe) establishes a persistent network connection to a known C2 IP address followed closely by the invocation of common command-line utilities (cmd, powershell, tasklist, etc.) used for file and process management.

This rule identifies DNS queries or web requests directed toward a known list of domain names associated with the 'ShipmentsFree' family of shipping-rebate scams. These scams are typically designed to lure consumers into unknowingly signing up for recurring, undisclosed subscription services.

Detects a sequence of Tox P2P protocol packets consisting of a Cookie Request, Cookie Response, and Crypto Handshake within a single network flow. This pattern is indicative of the Tox P2P protocol, which is sometimes abused by malware (e.g., AvisLoader) for command-and-control (C2) communications to evade traditional network inspection.
Detects lateral movement (SMB, RDP, WinRM) performed by a host within 5 minutes of communicating with specific commercial LLM APIs. This rule targets behaviors indicative of automated lateral movement driven by an LLM-based C2, excluding common administrative tools, standard business hours, and frequently used processes.

Detects network activity associated with the GHAPPIER implant beaconing to a hardcoded command and control (C2) server. The rule monitors for established TCP connections on port 15152 that contain specific JSON status indicators and the string 'ghappier' in the payload, which are characteristic of this malware's communication protocol.
This rule detects the execution of the Xray proxy utility (xray-core) when launched by the RemoteApp workspace broker process (wkspbroker.exe) or located within the RemoteApp Gateway application data folder. This behavior is indicative of an adversary using proxy tools to facilitate command-and-control communication or network traffic tunneling via trusted remote access infrastructure.
This rule identifies potential malicious activity by detecting the presence of known malicious file hashes (SHA256 and MD5) on endpoints and monitoring for DNS queries or network connections to a known malicious staging domain (yapw.life). The detection correlates file execution, file activity, and network communication to identify stages of an attack such as malware installation or C2 communication.
