Grok Automation — agentic threat model
Grok Automation is a local RPA-style Chrome extension with low agentic autonomy, posing primarily client-side security risks such as session hijacking or malicious extension updates rather than complex LLM-orchestration vulnerabilities.

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 extension itself does not host or train foundation models; it acts as a client-side automation wrapper for Grok. Threats to L1 (adversarial prompts, model stealing) are inherited from Grok's backend rather than managed by this extension.
Not certain from the listing — The extension processes a local text list of prompts and downloads generated media. There is no vector database or complex RAG pipeline mentioned. Data operations are limited to local file system writes (downloads) and DOM reading.
The extension uses a simple local batch execution framework (1-6 parallel workers, rate-limit handling) rather than a complex LLM agent framework. The primary threat is insecure DOM manipulation or state tracking leading to UI-redirection or local resource exhaustion.
Runs locally as a Chrome extension. The infrastructure is the user's local browser environment. Key threats include extension-level privilege escalation, malicious updates (since it is closed source), or unauthorized access to the user's active Grok session/cookies.
Not certain from the listing — There is no mention of built-in evaluation, guardrails, or observability logging, other than local progress saving. It relies entirely on Grok's native guardrails for content filtering.
The extension claims '100% local — no servers, no uploads, no telemetry,' which is a strong privacy control. However, as a closed-source extension, there is no independent audit or compliance certification mentioned to verify these claims.
Not certain from the listing — The extension operates in isolation on the user's browser and does not interact with an external agent ecosystem, marketplaces, or other multi-agent orchestrators.
