@whalent/agent@0.3.448
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe automatic global self-update and opaque implementation create a meaningful dangerous capability, but static evidence does not prove an active malicious attack. The package has no install lifecycle hook.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent CLI in a mode that is supervised.
Impact
A CLI invocation can replace the globally installed wrapper with a newer package release, expanding supply-chain exposure beyond the originally installed version.
Mechanism
The obfuscated entrypoint calls its update routine during main startup and uses a child process to request npm global installation of the wrapper package.
AI rationale
The automatic global self-update and opaque implementation create a meaningful dangerous capability, but static evidence does not prove an active malicious attack. The package has no install lifecycle hook.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes dist/index.cjs as its executable and has no npm install lifecycle hook.
- The executable runs a synchronous npm global install for WRAPPER_PKG_NAME at a selected version.
- On normal executable startup it invokes the update routine before supervising the core process.
Evidence against
- No install, preinstall, or postinstall script is declared.
- The observed install targets the package's own wrapper name, not a foreign agent configuration surface.
- No credential collection or network exfiltration sink was established in the inspected entrypoint excerpts.
