Background
Kamasada-Nusta-Buaibdan is an npm package that is part of a broader campaign involving the tea.xyz token reward system. This package, like many others in the campaign, is designed to manipulate npm's package registry by automatically generating and publishing derivative packages. Its primary function is to inflate developer reputation scores for token rewards, but this comes at the cost of security and integrity within the npm ecosystem.
Vulnerability Detail

It generates random package names, often themed around Indonesian culture, and continuously republishes these variants to pollute the npm registry. This behavior not only compromises the integrity of the npm ecosystem but also poses risks to developers who may unknowingly use these compromised packages, leading to potential security breaches in their applications.
How To Fix
