Detects the unauthorized injection of the 'GEMINI_TRUST_WORKSPACE=true' environment variable via process command lines or shell environments. This rule identifies potential exploitation attempts related to CVE-2026-12537 by flagging instances where this variable is set outside of defined, trusted CI/CD runner environments.

Detects Python processes that combine potentially dangerous pickle deserialization (pickle.loads) with network-fetching libraries (urllib, requests, socket) and decoding methods (b64decode, fromhex). This pattern is consistent with backdoors or remote access tools (RATs) that fetch encoded payloads over the network and execute them directly in memory via deserialization.

Detects Python processes executing complex, multi-layered decoding chains (Base64, ROT13, and Hex) in their command line arguments. This pattern is often used by malicious AI skill backdoors, such as ClawHub, to obfuscate payload execution and evade signature-based detection.

Detects outbound network connections initiated by common AI agent runtime processes (Python, Node.js, OpenClaw) to external destinations that are not identified as known AI service providers, specifically focusing on non-standard ports or the use of WebSocket protocols. This behavior may indicate an AI agent being used for unauthorized data exfiltration, command-and-control communication, or interaction with an unverified external service.

Detects high volumes of file operations (creation, rename, or modification) where files are given extensions typically associated with ransomware (e.g., .locked, .encrypted). The rule aggregates activity by process and endpoint and triggers an alert when the number of such operations exceeds a defined threshold, while excluding known legitimate backup and security software.

Detects unauthorized processes, such as shells, scripting engines, or command-line utilities, that attempt to display or access environment variables containing sensitive cloud credential patterns (e.g., AWS_ACCESS, API_KEY). This behavior often indicates an attempt to steal cloud provider credentials from the host environment.

Detects the download of a standalone CPython 3.10.18 interpreter from github.com/astral-sh/python-build-standalone using curl, followed by the extraction of the compressed archive using tar. This behavior is associated with the macOS.Gaslight malware's secondary collection module installer, which likely prepares a localized Python environment to execute further malicious tasks.

Detects the AMOS infostealer staging collected system data by using the macOS ditto utility to compress information into a hidden .hipr directory. The rule identifies the execution of ditto with .hipr in the command line in conjunction with the creation of User_Name.txt and System_Information.txt within that same directory.

Detects unauthorized processes reading, copying, or renaming Kerberos ticket cache files (ccache) located in common temporary directories. This behavior is often associated with credential theft and potential Pass the Ticket attacks where adversaries attempt to extract session credentials to perform lateral movement or privilege escalation.

Detects instances where VS Code extension-related processes (such as amazonq-lsp or extensionHost) spawn shell processes (bash/sh) that subsequently initiate network activity via curl or wget. This pattern is indicative of potential exploitation where malicious workspace configuration files (e.g., .amazonq/mcp.json) are used to execute shell commands with unauthorized access to cloud credentials.
