AgentScale — agentic threat model
AgentScale presents a high-risk profile due to its integration with sensitive personal tools (email, calendar) and its ability to surf the web, which exposes it to indirect prompt injection and subsequent unauthorized actions.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
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 — The specific foundation models are undisclosed. However, because the agent surfs the internet, it is highly vulnerable to indirect prompt injection from malicious web pages, which could reprogram the model to draft unauthorized emails.
Not certain from the listing — No details are provided regarding data storage, vector databases, or RAG pipelines. The primary data risk is the exfiltration of sensitive email and calendar data ingested during operations.
Not certain from the listing — The orchestration framework is proprietary. The integration of tools like email writing, calendar scheduling, and web browsing presents a high risk of tool misuse if the agent is manipulated by untrusted web content.
Not certain from the listing — Hosting, sandboxing, and secrets management details are not specified. Compromise of the deployment infrastructure could expose user credentials and API tokens for email and calendar services.
Not certain from the listing — There is no mention of real-time monitoring, guardrails, or logging mechanisms to detect anomalous behavior, such as the agent sending emails to unauthorized recipients.
Not certain from the listing — No compliance certifications (e.g., SOC2, GDPR) or explicit identity and access management policies are detailed for this closed-source assistant.
Not certain from the listing — The agent is described as a standalone personal assistant with no explicit multi-agent or marketplace interactions, though it could interact with other agents indirectly via email.
