Attackers can exploit GenAI tools through prompt injection, malicious MCP (Model Context Protocol) servers, or poisoned plugins to establish command-and-control (C2) channels or exfiltrate sensitive data. Given the network access capabilities of AI agents, adversaries may manipulate them to beacon to external servers, download malicious payloads, or transmit harvested credentials and documents. The Elastic detection rule \u003ccode\u003e9050506c-df6d-4bdf-bc82-fcad0ef1e8c1\u003c/code\u003e focuses on identifying such anomalous network connections originating from a predefined list of GenAI processes, excluding known legitimate domains. The rule has been actively maintained since its creation on December 4, 2025, with its latest update on April 29, 2026.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAdversary compromises a GenAI tool on a macOS system through prompt injection, malicious MCP servers, or poisoned plugins.\u003c/li\u003e\n\u003cli\u003eThe compromised GenAI tool is configured to connect to an attacker-controlled domain for C2.\u003c/li\u003e\n\u003cli\u003eThe GenAI process initiates a network connection attempt to the unusual domain using standard web protocols (HTTP/HTTPS).\u003c/li\u003e\n\u003cli\u003eThe macOS system\u0026rsquo;s network stack resolves the attacker\u0026rsquo;s domain to its corresponding IP address.\u003c/li\u003e\n\u003cli\u003eThe GenAI process sends data to the attacker-controlled domain, potentially including sensitive information.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the C2 channel to send commands to the compromised GenAI tool.\u003c/li\u003e\n\u003cli\u003eThe GenAI tool executes the commands, potentially leading to further compromise or data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eCompromised GenAI tools can lead to data exfiltration, unauthorized access to sensitive information, and the establishment of persistent C2 channels within an organization\u0026rsquo;s network.
