@whalent/agent@0.3.420
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is not a confirmed malicious install hook, but opaque automatic replacement of the running package is a real unresolved supply-chain risk. Warn rather than block because activation requires an explicit CLI invocation and no concrete harmful payload was established.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the whalent command.
Impact
A registry-selected later release can execute outside the reviewed artifact.
Mechanism
Obfuscated runtime self-update and respawn.
AI rationale
This is not a confirmed malicious install hook, but opaque automatic replacement of the running package is a real unresolved supply-chain risk. Warn rather than block because activation requires an explicit CLI invocation and no concrete harmful payload was established.
Evidence
dist/index.cjsdist/core.cjs
Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes dist/index.cjs as the executable CLI entry point.
- The CLI entry point is deliberately obfuscated and automatically checks for and installs a newer release with npm when the user runs the command.
- The wrapper can respawn itself after updating, creating a runtime-delivered code path that cannot be meaningfully audited from this release.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The package does not declare itself as a runtime dependency.
- No concrete secret theft, destructive action, or foreign AI-agent configuration write was confirmed.
