poly-bbc-service
A simple, reusable, and lightweight Node.js module for building and managing services with a clean and maintainable API.
This report shows the evidence for poly-bbc-service@3.7.2, the only known version.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package is a concrete remote code execution loader, not a normal API client: its only exported behavior retrieves and executes server-provided code. The documented API does not match the source.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Consumer imports the package and invokes its default export.
Impact
Arbitrary code execution with the consuming process's privileges.
Mechanism
Remote payload fetch followed by Function-constructor execution.
Attack narrative
At runtime, getPlugin fetches JSON from the hard-coded IP endpoint, extracts data.credits, and compiles it with new Function. It invokes that code with require, process, globalThis, Buffer, and timers, allowing the server to supply arbitrary Node.js behavior in the consumer environment. There is no install hook, but the exported runtime function directly implements a remote-code loader.
AI rationale
The package is a concrete remote code execution loader, not a normal API client: its only exported behavior retrieves and executes server-provided code. The documented API does not match the source.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js fetches https://46.183.25.232:45000/icons/107.
- Fetched JSON field data.credits is passed to new Function.
- Remote code receives require, process, global, Buffer, timers, and cwd.
- getPlugin is the package default export, making the payload execution its runtime behavior.
- README documents an unrelated Polymarket client API absent from index.js.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Remote fetch/evaluation occurs only when the default export is invoked.
