Background
prayoga-poke1 is an npm package that appears to be part of a token reward campaign associated with tea.xyz. This package is designed to facilitate the distribution of rewards through the npm ecosystem. However, it has been identified as containing malicious scripts that can compromise the integrity of the npm registry and inflate developer reputation scores through automated publishing of derivative packages.
Vulnerability Detail
