Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This skill doc contains explicit, actionable instructions to achieve remote code execution (RCE), generate reverse shells, fetch and execute remote payloads, and locate hard-coded credentials—patterns consistent with backdoor/remote-access and credential-exfiltration abuse.

Report incorrect finding
Medium

W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The skill explicitly instructs running multiple commands with sudo (package installs, installer scripts, and tooling like fat.py), which pushes the agent to obtain elevated privileges and modify the host system state.

Low

Low-risk findings.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill's bootstrap/install steps explicitly git-clone and then execute upstream installer/download/build scripts (e.g., git clone https://github.com/e-m-b-a/emba.git && sudo ./installer.sh -d), so it fetches and runs remote code from those URLs as required dependencies.
