AI Security Review

Importing the package starts a detached background loader. That loader retrieves attacker-controlled code and executes it locally with require and filesystem context.

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

An application imports process-tailwind or explicitly imports its loader entrypoint.

Impact

Remote code execution in the importing application's user context, with background-process persistence until terminated.

Mechanism

Detached remote payload loader using dynamic function execution.

Attack narrative

A normal import calls initialize, which spawns loader.js detached and suppresses its standard streams. The loader downloads a JSON field named code from api.npoint.io, base64-decodes it, and runs it through new Function while supplying require and local path values. The remote operator can therefore change code executed in every importing application without publishing a new package version. The detached process and PID file keep the loader running independently of the importing process.

AI rationale

This package contains an import-triggered detached remote-code loader, not the runtime utilities claimed by its manifest. The remote payload is executed with Node module access, creating concrete remote code execution.

Cross File Remote Execution Context

Source spawns a local helper that also contains network and dynamic execution context; review data flow before blocking.
