Background

rinto-poke39 is an npm package that has been identified as part of a malicious campaign targeting the npm registry.

The malicious nature of this package compromises the integrity of the npm ecosystem by introducing harmful scripts and altering package metadata.

Vulnerability Detail

The vulnerability in rinto-poke39 stems from its inclusion in a malicious campaign that utilizes autopublish scripts to generate and publish numerous derivative packages with randomized names.
