@whalent/agent@0.3.407
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis package does not contain an npm install hook or a self-dependency, but its obfuscated runtime global updater with lifecycle-script allowance is a concrete unresolved execution risk. Static inspection cannot establish malicious intent or a confirmed payload.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent CLI.
Impact
A later registry package and its allowed lifecycle scripts could execute in the user's global npm environment.
Mechanism
Obfuscated runtime global npm update through a child process.
AI rationale
This package does not contain an npm install hook or a self-dependency, but its obfuscated runtime global updater with lifecycle-script allowance is a concrete unresolved execution risk. Static inspection cannot establish malicious intent or a confirmed payload.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The published CLI entry point and its 16 MB core bundle are deliberately string and control-flow obfuscated, which prevents meaningful static verification of their behavior.
- When the CLI runs, the wrapper invokes npm with a global install argument for a wrapper package and enables selected lifecycle scripts.
- The executable can run child processes and carries an opaque remote-update mechanism, leaving a supply-chain execution surface that cannot be safely resolved from the shipped source.
Evidence against
- package.json has no preinstall, install, or postinstall hook; its only lifecycle-like hook is prepublishOnly.
- The manifest has no dependency on its own package name.
- No concrete credential theft, destructive command, or exfiltration endpoint was recoverable from the inspected source.
