Background

The shared_amphibian_z3n package is part of the npm ecosystem, which is widely used for JavaScript development. This package has been identified as part of a malicious campaign associated with the tea.xyz token reward system. It is designed to inflate developer reputation scores by automatically generating and publishing derivative packages with randomized names, which can lead to pollution of the npm registry and potential security risks for developers using these packages.

Vulnerability Detail

The vulnerability originates from the malicious code embedded within the shared_amphibian_z3n package. This code modifies the package.json file to remove private flags, alters version numbers, and generates random package names, primarily themed around Indonesian culture. The continuous republishing of these variants can lead to a cluttered npm registry, making it difficult for developers to find legitimate packages and increasing the risk of inadvertently using compromised software.

How To Fix

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

npm uninstall shared_amphibian_z3n

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