Core runtime for Whalent Agent
AI Security Review
scanned 7d ago · by lpm-firewall-aiThe package has no install hook, and inspected command execution is consistent with its stated agent-runtime purpose. Extensive obfuscation across its runtime bundles prevents a clean assessment, but the inspected source does not establish a concrete attack, so warn rather than block.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the packaged CLI or MCP executable.
Impact
No specific harmful effect is confirmed; unresolved runtime behavior warrants a warning.
Mechanism
The bundles obscure control flow; command execution is present in the main CLI, but its full behavior could not be resolved from inspected source.
AI rationale
The package has no install hook, and inspected command execution is consistent with its stated agent-runtime purpose. Extensive obfuscation across its runtime bundles prevents a clean assessment, but the inspected source does not establish a concrete attack, so warn rather than block.
Evidence
dist/index.cjsdist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 76.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The manifest exposes a CLI entrypoint and contains no install lifecycle scripts.
- The MCP executable uses a string-table rotation pattern that obscures its behavior; the bundled source is difficult to assess statically.
- The main CLI bundle is also heavily obfuscated and includes command execution, leaving its full behavior unresolved.
Evidence against
- The package describes itself as an agent runtime and declares SSH and terminal dependencies consistent with command-capable agent functionality.
- The inspected dynamic function construction in the MCP bundle occurs in bundled schema compilation code; it does not establish a payload attack.
