A consumer calling the default export triggers a request to a hard-coded IP endpoint and executes server-supplied JavaScript. The endpoint controls code with Node process and module-loading capabilities.

Static reason

One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review

Trigger

Consumer invokes the package default export (getPlugin).

Impact

Remote operator can run arbitrary code in the consuming process context.

Mechanism

Remote payload fetch followed by Function-based execution.

Attack narrative

The exported getPlugin function fetches JSON from a hard-coded remote IP and compiles data.credits with Function. It supplies require, process, global, Buffer, and filesystem-relative context to that untrusted payload, allowing the endpoint operator to execute arbitrary Node.js code whenever a consumer calls the export.

Rationale

The advertised utility package contains an undocumented remote code loader whose payload is controlled by a hard-coded external endpoint. Although it is not install-time execution, this is a concrete remote-code-execution capability inconsistent with the package purpose.
