Core runtime for Whalent Agent
AI Security Review
scanned 8d ago · by lpm-firewall-aiStatic inspection found no confirmed malicious behavior or install hook. The obfuscated executable entrypoint leaves material runtime behavior unresolved, so the package should be warned rather than marked clean or blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing the package or launching its CLI entrypoint.
Impact
Potentially unsafe runtime behavior cannot be ruled out, but no specific compromise or data loss was established.
Mechanism
The main entrypoint contains extensive encoded code; the inspected source did not establish whether this conceals harmful behavior.
AI rationale
Static inspection found no confirmed malicious behavior or install hook. The obfuscated executable entrypoint leaves material runtime behavior unresolved, so the package should be warned rather than marked clean or blocked.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 74.0% confidence as Unknown with high false-positive risk.
Evidence for warning
- The package manifest routes its main entrypoint and CLI to dist/index.cjs, whose full runtime behavior remains unresolved after bounded inspection.
- The included MCP bundle uses heavily encoded identifiers and a decoder wrapper.
- The manifest declares no lifecycle scripts, and the observed dynamic function construction in the MCP bundle is part of local code generation rather than evidence of a remote payload loader.
Evidence against
- The package describes itself as the Whalent Agent runtime and depends on SSH and pseudo-terminal libraries, consistent with that stated role.
- No concrete credential theft, destructive behavior, or payload execution was confirmed in the inspected excerpts.
