Agent Commander: Promptware-Powered Command and Control

Summary

Agent Commander is a novel promptware-powered command and control (C2) server designed to hijack and manage AI agents at scale. Unlike traditional C2, it operates at the agent layer, providing all commands in natural language rather than raw OS commands. The system demonstrates how agents like Kimi Claw, OpenClaw, and NanoClaw can be compromised through methods such as indirect prompt injection, appsec issues, or supply chain vulnerabilities. Persistence is achieved by abusing agent functionalities like OpenClaw's "HEARTBEAT.md" file, which runs every 30 minutes and often uses weaker models, making detection harder. Once compromised, agents can perform diverse objectives, including host enumeration, data exfiltration (e.g., screenshotting inboxes), monitoring third-party websites, and even executing influence campaigns. The research highlights a conceptual shift where agents become a new execution layer, effectively acting as "potential malware" themselves.

Key takeaway

For MLOps Engineers or AI Security Engineers deploying and managing AI agents, recognize that agents themselves can become a new C2 layer, acting as "potential malware" without traditional installations. You should implement daily patching for agent platforms like OpenClaw, run agents on dedicated, isolated systems, and avoid using weaker models for cost savings in critical functions like heartbeats. Additionally, establish robust prompt monitoring and a kill-switch mechanism to immediately disable compromised agents and rotate credentials.

Key insights

Promptware-powered C2 enables large language model agents to be hijacked and controlled via natural language commands, forming a new attack surface.

Principles

• Agents are a new execution layer.
• LLM output is inherently untrusted.
• Weaker models in heartbeats increase risk.

Method

Agent Commander establishes C2 by injecting promptware into agents, which then check in for natural language tasks, allowing continuous control and objective execution.

In practice

• Monitor prompts for anomalous activity.
• Isolate agents on dedicated systems.
• Implement agent kill-switches.
