@whalent/agent@0.3.363
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has no registry install lifecycle hook, but opaque runtime update and manifest-resolution code prevents a clean determination. The evidence supports a non-blocking warning for a possible staged payload path, not proof of malware.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the whalent CLI.
Impact
A supplied or resolved manifest could stage helper content, but the inspected source does not prove an unsolicited payload download or execution sink.
Mechanism
Obfuscated entrypoint code performs an update check, while the obfuscated core accepts a helper manifest URL from environment configuration.
AI rationale
The package has no registry install lifecycle hook, but opaque runtime update and manifest-resolution code prevents a clean determination. The evidence supports a non-blocking warning for a possible staged payload path, not proof of malware.
Evidence
dist/index.cjsdist/core.cjs
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The executable entrypoint is an intentionally obfuscated wrapper that contains an automatic wrapper-update check.
- The 15 MB obfuscated core accepts a helper manifest URL from an environment variable, leaving remotely supplied helper resolution opaque to static review.
- The package is a CLI wrapper, so these behaviours activate when its command is run.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The inspected manifest does not runtime-depend on its own package name.
