Hermes Agent — agentic threat model
Hermes Agent presents an extremely high-risk profile due to its combination of persistent shell access, browser automation, and a self-improving learning loop. Without strict sandboxing and robust input sanitization, its extensive toolset and remote accessibility make it a prime target for remote code execution and host compromise.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — likely utilizes Nous Research's Hermes series models. Vulnerable to prompt injection, adversarial examples, and model alignment drift as the agent self-improves and modifies its behavior over time.
Persistent memory, user modeling, and past conversation search require a local or cloud vector database/state store. Vulnerable to memory poisoning and data exfiltration of sensitive user history.
Features a self-improving learning loop, MCP connectivity, and plugins. Vulnerable to insecure tool execution, prompt injection leading to shell command execution, and malicious plugin exploitation.
Supports local/cloud deployment with persistent shell access and browser automation. Highly vulnerable to host compromise, privilege escalation, and container escape if not strictly sandboxed.
Not certain from the listing — no built-in evaluation, guardrails, or monitoring tools are mentioned. Gaps in logging could allow malicious shell commands or memory drift to go undetected.
Not certain from the listing — being an open-source developer-focused tool, it lacks explicit mention of enterprise identity, access management (IAM), or compliance frameworks.
Supports MCP (Model Context Protocol) and multi-channel use cases (e.g., Telegram). Vulnerable to trust abuse from external MCP servers or malicious inputs received via Telegram.

These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification.
