@whalent/agent@0.3.410
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis release automatically updates a global executable at runtime from opaque code, which is unsafe and not adequately auditable. There is no install lifecycle hook or confirmed direct malicious action in the inspected package.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent CLI in its normal supervised mode.
Impact
The installed global CLI can be replaced with a registry-selected release without a separate explicit update command.
Mechanism
Obfuscated runtime self-update through a global npm installation.
AI rationale
This release automatically updates a global executable at runtime from opaque code, which is unsafe and not adequately auditable. There is no install lifecycle hook or confirmed direct malicious action in the inspected package.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The CLI entrypoint is heavily obfuscated, including a runtime string decoder, which prevents transparent review of its behavior.
- Every normal CLI invocation calls an automatic wrapper-update routine before starting the supervised core.
- The update code uses npm global installation for the package name and selected version, allowing runtime replacement of the globally installed tool.
Evidence against
- package.json has no preinstall, install, or postinstall hook; prepublishOnly is not run for normal consumers.
- No concrete credential theft, data exfiltration, destructive command, or foreign AI-agent configuration write was confirmed by source inspection.
- The bundled Python sidecar is a Jupyter kernel protocol helper rather than an install-time launcher.
