Background
teagood-cuekin2 is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate the automatic generation and publication of derivative packages, often with randomized names. Its primary functionality revolves around inflating developer reputation scores in exchange for tea protocol token rewards. However, its malicious nature poses significant risks to users and the integrity of the npm registry.
Vulnerability Detail
