@whalent/agent@0.3.462
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe normal CLI performs opaque self-updating and global replacement without an explicit update command. Static inspection did not establish credential exfiltration, destructive activity, or an npm lifecycle attack.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent command.
Impact
A normal command invocation can replace the globally installed wrapper with a network-selected release, creating a persistence and supply-chain risk.
Mechanism
The obfuscated CLI invokes its persistence and update routines, then spawns npm with a global self-package version argument.
AI rationale
The normal CLI performs opaque self-updating and global replacement without an explicit update command. Static inspection did not establish credential exfiltration, destructive activity, or an npm lifecycle attack.
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 manifest exposes dist/index.cjs as the whalent command and contains no install lifecycle hook.
- The CLI always reaches a persistence prompt and wrapper-update routine during normal execution.
- The update routine installs a selected version of its own wrapper package globally through a spawned npm command; the shipped runtime is heavily obfuscated.
Evidence against
- No package-install lifecycle script is declared.
- No credential collection or destination-specific exfiltration was confirmed in the inspected entrypoint.
