Background
The intan-15 package is part of the npm ecosystem, which is widely used for JavaScript package management. It is often utilized by developers to manage dependencies in their projects. However, this package has been identified as part of a malicious campaign that aims to exploit the npm registry by flooding it with derivative packages that have randomized names. This behavior not only compromises the integrity of the npm ecosystem but also poses risks to developers who may unknowingly use these compromised packages.
Vulnerability Detail
The vulnerability in the intan-15 package originates from its association with the tea.xyz token reward campaign. This package contains malicious scripts designed to automatically generate and publish derivative packages with altered metadata, including the removal of private flags from package.json and the generation of random package names. The continuous republishing of these variants leads to pollution of the npm registry, which can mislead developers and inflate reputation scores for malicious actors. The ramifications include potential security risks for users who install these packages, as they may inadvertently introduce vulnerabilities into their applications.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall intan-15If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
