@whalent/agent@0.3.439
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has no automatic npm install hook, so the evidence does not establish an install-time attack. Its opaque, automatic global self-update capability is nevertheless a meaningful supply-chain risk that warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the whalent executable or importing its main entrypoint.
Impact
A later package release selected by the updater can replace the global executable; opaque update logic makes that supply-chain behavior difficult to independently verify.
Mechanism
The obfuscated entrypoint calls its update routine, selects a wrapper version, and invokes a global package installation through a child process.
AI rationale
The package has no automatic npm install hook, so the evidence does not establish an install-time attack. Its opaque, automatic global self-update capability is nevertheless a meaningful supply-chain risk that warrants a warning.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Package metadata exposes the bundled wrapper as both the main module and the whalent executable.
- The executable unconditionally invokes its wrapper update check before supervising the core runtime.
- The update path installs a selected version of the wrapper package globally through a child-process call.
- The distributed entry bundle is deliberately obfuscated, preventing transparent auditing of the update and execution path.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The update behavior is activated when the wrapper runs, rather than during npm installation.
