@whalent/agent@0.3.414
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is not proven malware because there is no install lifecycle trigger or confirmed exfiltration. However, automatic remote updating plus extensive obfuscation leaves a material unresolved execution risk.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the whalent CLI.
Impact
A registry-selected update can replace the executed runtime; hidden behavior cannot be fully assessed.
Mechanism
Obfuscated runtime self-update and core supervision.
AI rationale
This is not proven malware because there is no install lifecycle trigger or confirmed exfiltration. However, automatic remote updating plus extensive obfuscation leaves a material unresolved execution risk.
Evidence
dist/index.cjsdist/core.cjs
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The shipped CLI and core runtime are heavily obfuscated, preventing reliable audit of their decoded behavior.
- Running the CLI automatically invokes an update routine before supervising the core runtime.
- The update routine queries npm and can install a newer wrapper release, creating an opaque remote code-update path.
- The README describes remote commands and periodic helper downloads, but the shipped implementation is not transparently reviewable.
Evidence against
- package.json contains only a prepublishOnly hook and no install, preinstall, or postinstall hook.
- No concrete credential-exfiltration endpoint or install-time foreign control-surface mutation was established from the inspected source.
