Description

The npm package udin-teh28-sluey contains malicious code associated with the tea.xyz token reward campaign that flooded npm with over 15,000 spam packages in 2024. These packages include autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The malicious payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants to manipulate developer reputation scores for token rewards. This activity pollutes the npm registry with spam and potentially deceptive packages.

Impact

This malicious package pollutes the npm registry by continuously publishing derivative packages with randomized names, which can mislead developers and automated systems relying on package metadata. It manipulates developer reputation scores tied to the tea.xyz token reward system, potentially enabling fraudulent gains. While no direct exploitation or code execution impact is described, the campaign degrades trust in the npm ecosystem and may cause indirect harm through dependency confusion or supply chain pollution.

Defensive guidance

Users and organizations should avoid using the udin-teh28-sluey package and related derivative packages. Registry maintainers and security teams should monitor and remove such spam packages to preserve ecosystem integrity. Since this is a malicious package rather than a vulnerability in legitimate software, remediation focuses on detection and removal rather than patching.

Summary

The npm package udin-teh28-sluey is part of a large-scale malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. The malicious code modifies package.json by removing private flags and changing version numbers to enable repeated publication. This behavior inflates developer reputation scores fraudulently and floods the npm registry with spam packages, degrading the ecosystem's integrity.
