@whalent/agent@0.3.434
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has dangerous code-execution capability and opaque runtime logic, but no verified malicious install chain or concrete attack behavior. It should be warned for review rather than blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent CLI and a caller sends an execute request to the sidecar.
Impact
A controlling caller could run arbitrary Python in the selected local Jupyter environment.
Mechanism
Obfuscated agent runtime with kernel code execution support.
AI rationale
The package has dangerous code-execution capability and opaque runtime logic, but no verified malicious install chain or concrete attack behavior. It should be warned for review rather than blocked.
Evidence
dist/jupyter_sidecar.pydist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI entrypoint is deliberately control-flow obfuscated; the manifest also lists javascript-obfuscator.
- The bundled Jupyter sidecar accepts an execute request and passes supplied code to a Python kernel.
- The package exposes its obfuscated entrypoint as the whalent CLI.
Evidence against
- package.json has only a prepublishOnly script, not an install lifecycle hook.
- There is no runtime dependency on this package's own name.
- No concrete credential theft, destructive action, or unconsented install-time control-surface mutation was established.
