@whalent/agent@0.3.378
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package is not malicious under the install-hook policy because it has no registry install lifecycle hook. Its obfuscated self-updating agent wrapper is nevertheless an unresolved dangerous capability and should be warned on.
Static reason
One or more suspicious static signals were detected.
Trigger
User invocation of the whalent CLI.
Impact
A user who runs the CLI may receive and execute a changed core runtime outside the originally inspected wrapper.
Mechanism
Obfuscated runtime self-update and global core-package installation.
AI rationale
The package is not malicious under the install-hook policy because it has no registry install lifecycle hook. Its obfuscated self-updating agent wrapper is nevertheless an unresolved dangerous capability and should be warned on.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The published CLI entrypoint is deliberately obfuscated, preventing normal source audit.
- When the CLI runs, the wrapper includes automatic update logic.
- The wrapper can install a core package globally through npm at runtime.
Evidence against
- The manifest has no preinstall, install, or postinstall hook.
- The executable behavior is triggered by invoking the whalent command, not by package installation.
- No hard-coded network endpoint or direct credential-exfiltration path was confirmed from the inspected source.
