Background
ucok-poke63 is an npm package that appears to be part of a larger campaign aimed at exploiting the npm ecosystem for token rewards. This package, like others in the campaign, is designed to manipulate the npm registry by generating and publishing numerous derivative packages with altered metadata. The malicious nature of this package poses a significant risk to developers and users relying on npm for package management.
Vulnerability Detail
The vulnerability in ucok-poke63 originates from its association with the tea.xyz token reward campaign, which floods the npm registry with malicious packages. The package contains scripts that automatically modify the package.json file by removing private flags, changing version numbers, and generating random package names. This behavior not only inflates developer reputation scores but also pollutes the npm registry, making it difficult for users to find legitimate packages. The ramifications include potential security risks for applications that depend on this package, as well as a compromised npm ecosystem.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall ucok-poke63If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
