Background
The tehah-kalian-bautka package is part of a series of npm packages associated with the tea.xyz token reward campaign. These packages are designed to automate the generation and publication of derivative packages, often with randomized names, to inflate developer reputation scores for token rewards. The malicious nature of this package lies in its ability to modify essential files and republish variants, which can lead to significant pollution of the npm registry.
Vulnerability Detail
The vulnerability originates from the package's malicious payload, which alters the package.json file by removing private flags and changing version numbers. It generates random package names, often themed around Indonesian culture, and continuously republishes these variants. This behavior not only compromises the integrity of the npm registry but also poses risks to developers who may unknowingly use these tainted packages, leading to potential security breaches in their applications.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall tehah-kalian-bautka
