trailofbits-firebase-apk-scanner — agentic threat model
This agent poses a moderate-to-high security risk primarily due to its ingestion of untrusted binary files (APKs) and execution of local unpacking tools, which could be targeted for command injection or path traversal if not strictly sandboxed.

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 listing does not specify which LLM is used to drive this skill. Standard LLM risks like prompt injection via malicious strings embedded in APK metadata or decompiled code could lead to altered scan reports or hijacked reasoning.
The agent processes uploaded APK files and extracts configuration data. Risks include processing malicious or malformed APKs designed to exploit the parser, or data leakage if scanned APKs contain sensitive proprietary code or keys that are cached or logged.
The agent orchestrates bundled tooling to unpack and analyze APKs. Insecure tool integration (e.g., passing unsanitized APK filenames or metadata to shell commands during unpacking) could lead to command injection or path traversal.
Not certain from the listing — The hosting environment is unspecified. If run without strict sandboxing, unpacking untrusted APKs poses a severe risk of container escape or host compromise via zip-slip or binary exploitation of decompilers.
Not certain from the listing — No logging, evaluation, or guardrail mechanisms are described. Gaps here could allow silent failures or undetected exploitation attempts during APK analysis.
Not certain from the listing — There is no mention of access controls, authentication, or compliance frameworks. Since it scans for vulnerabilities, unauthorized access to the tool could allow attackers to scan third-party APKs to find zero-days.
This is a single-purpose security skill with no indicated multi-agent or marketplace integrations. Ecosystem risks are minimal, restricted to potential supply-chain vulnerabilities in the bundled unpacking tools.
