Background

The riyanto-poke98 package is part of the npm ecosystem, which is widely used for JavaScript package management. This package, like many others, is intended to provide developers with tools and libraries to enhance their applications. However, it has been identified as part of a malicious campaign that aims to exploit npm's publishing system by flooding it with derivative packages that can harm the integrity of the registry and the applications relying on it.

Vulnerability Detail

The vulnerability in riyanto-poke98 stems from its association with a malicious campaign that modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior is designed to inflate developer reputation scores for token rewards associated with the tea protocol. The malicious payload continuously republishes variants of the package, polluting the npm registry and potentially compromising applications that depend on it.

How To Fix

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

npm uninstall riyanto-poke98

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