@whalent/agent@0.3.528
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 11h ago · by lpm-firewall-aiThe package has no install-time lifecycle hook, and the inspected dynamic-code match is consistent with bundled proxy resolution. The main CLI remains substantially obfuscated, leaving enough unresolved runtime risk to warrant a warning rather than a clean verdict or a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Launching the package CLI through its configured entrypoint.
Impact
The opaque runtime behavior leaves unresolved risk, but no specific compromise or harmful effect was confirmed.
Mechanism
The CLI uses runtime string decoding and includes npm command execution; the inspected excerpts do not establish harmful command arguments or a malicious payload.
AI rationale
The package has no install-time lifecycle hook, and the inspected dynamic-code match is consistent with bundled proxy resolution. The main CLI remains substantially obfuscated, leaving enough unresolved runtime risk to warrant a warning rather than a clean verdict or a 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 published CLI entrypoint is heavily obfuscated, including a decoder that reconstructs strings at runtime, which limits review of its behavior.
- The CLI contains code that runs npm commands to retrieve package version information; its full behavior is difficult to assess in the obfuscated bundle.
Evidence against
- The manifest lists only a publishing-time build hook, not an install-time hook.
- The dynamic function construction found in the MCP bundle is inside bundled PAC resolver code, consistent with evaluating proxy configuration; it does not establish a payload loader.
