Background
The lentengpride-tool is an npm package that has been identified as part of a broader malicious campaign targeting the npm registry. This package is designed to facilitate token reward schemes, which have been associated with the tea.xyz protocol. Its primary functionality revolves around automating the generation and publication of derivative packages, often with randomized names, to artificially inflate developer reputation scores. However, this functionality has been exploited to introduce malicious code that compromises the integrity of the npm ecosystem.
Vulnerability Detail
The vulnerability in lentengpride-tool stems from its malicious payload, which modifies the package.json file to remove private flags and alters version numbers. It generates random package names, often themed around Indonesian culture, and continuously republishes these variants to pollute the npm registry. This behavior not only affects the reputation of legitimate developers but also poses a risk of dependency confusion and potential exploitation of downstream projects that may unknowingly rely on these compromised packages.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall lentengpride-toolIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
