Real-time game item validator with daemon for client project updates
AI Security Review
scanned 12d ago · by lpm-firewall-aiThe package performs automatic remote code execution on import, with the remote signer controlling the code that passes verification. The signature check authenticates the signer but does not limit the executed code's capabilities.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
A consumer imports the package entrypoint.
Impact
The remote signer can cause code to run with the importing process's privileges.
Mechanism
The entrypoint starts lib/check-items.js, which downloads signed code from a fixed endpoint, verifies its signature, and evaluates it with access to require.
Attack narrative
Importing the package starts a detached helper that requests JavaScript from a fixed remote endpoint. The helper checks the response signature, then evaluates the code with Node's require function. The included server example signs and serves code, so the trusted signer can supply code that runs with the consumer process's privileges.
AI rationale
The package performs automatic remote code execution on import, with the remote signer controlling the code that passes verification. The signature check authenticates the signer but does not limit the executed code's capabilities.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package uses index.js as its entrypoint and defines no lifecycle scripts.
- Importing the entrypoint starts a detached helper process automatically.
- The helper fetches code from a fixed remote endpoint and executes the response with Node's require after checking its signature.
- The included server example signs and returns code for the remote execution flow.
Evidence against
- The helper exits when the response signature is invalid, limiting execution to code signed for its embedded public key.
