Background

slamet-poke91 is an npm package that has been identified as part of a malicious campaign targeting the npm registry. It is designed to participate in the tea.xyz token reward scheme, which has led to the proliferation of numerous derivative packages. These packages are typically used to inflate developer reputation scores through automated publishing scripts.

Vulnerability Detail

The vulnerability in slamet-poke91 originates from its malicious payload that modifies the package.json file. It removes private flags, alters version numbers, and generates random package names, primarily themed around Indonesian culture. This behavior not only compromises the integrity of the npm registry but also leads to the continuous republishing of these variants, polluting the ecosystem and potentially affecting other packages.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

npm uninstall slamet-poke91

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
