Background
nasrul-poke62 is an npm package that has been identified as part of a malicious campaign targeting the npm registry. This package, like others in the campaign, is designed to manipulate the npm ecosystem by generating and publishing numerous derivative packages with altered metadata. The primary function of these packages is to exploit the npm registry for token rewards associated with the tea.xyz protocol, thereby inflating developer reputation scores.
Vulnerability Detail

This behavior leads to the continuous republishing of variants, polluting the npm registry and potentially compromising the integrity of other packages. The origin of this vulnerability is linked to the tea.xyz token reward campaign, which employs autopublish scripts to automate the creation of these malicious packages.
How To Fix
