Arthur AI — agentic threat model

6.0AIVSS 6.0 · Medium

Arthur AI is a specialized video generation agent with low operational autonomy but high output non-determinism, presenting risks primarily related to resource abuse (GPU exhaustion), copyright infringement, and the generation of inappropriate content.

OWASP AIVSS score rationale

AIVSS = (CVSS_Base + AARS) × Mitigation_Factor, where AARS = (10 − CVSS_Base) × (Factor_Sum / 10) × ThM

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.

L1 · Foundation Models✓ mapped

Utilizes generative video and image foundation models. Key threats include adversarial prompt injection to bypass safety filters, model reprogramming, and the generation of copyright-infringing or highly offensive/NSFW visual content.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — The data pipeline for training or fine-tuning on specific styles (Anime, Manga) is undisclosed. Threats include training data poisoning and intellectual property/copyright disputes over training sets.

L3 · Agent Frameworks⚠ not certain from listing

Not certain from the listing — The internal orchestration framework for stitching scenes and generating long-form video is unknown. Potential threats include insecure handling of prompt variables and state management during long-form rendering.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — Hosting infrastructure is undisclosed but likely relies on heavy GPU rendering clusters. Primary threats include denial-of-service (resource exhaustion/wallet draining) due to the high computational cost of video generation.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — There is no public information on output monitoring or content guardrails. Gaps here could allow users to generate harmful, deepfake, or abusive video content undetected.

L6 · Security & Compliance (cross-cutting)⚠ not certain from listing

Not certain from the listing — Compliance controls, identity management, and copyright policies are not detailed. Risks include lack of user access controls and potential liability under emerging synthetic media regulations.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — The agent appears to operate as a standalone vertical tool with no explicit multi-agent or ecosystem marketplace integrations described.
