Background
The uyafru-tuit-dutut package is part of a series of npm packages associated with the tea.xyz token reward campaign. These packages are designed to manipulate the npm registry by automatically generating and publishing derivative packages with randomized names. This behavior is intended to inflate developer reputation scores for rewards within the tea protocol ecosystem. However, this package has been identified as containing malicious code that compromises its integrity.
Vulnerability Detail
The vulnerability originates from the package's malicious payload, which modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior leads to the continuous republishing of variants, polluting the npm registry and potentially affecting other developers and their projects. The malicious scripts (auto.js, autopublish.js, etc.) are designed to automate this process, making it difficult for users to detect the malicious activity.
