Description

The npm package bambang-semur92-sluey contains malicious code linked to the tea.xyz token reward campaign that flooded npm with over 15,000 spam packages in 2024. This malware uses autopublish scripts to automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants to inflate developer reputation scores and pollute the npm registry.

Impact

This malware campaign pollutes the npm registry with thousands of spam packages, potentially misleading developers and automated systems that rely on package metadata and reputation scores. It undermines the integrity of the npm ecosystem by artificially inflating developer reputations and increasing noise in package searches and dependency resolution. There is no indication of direct exploitation or compromise of user systems beyond registry pollution and reputation manipulation.

Defensive guidance

The recommended mitigation is to avoid installing packages associated with the tea.xyz token reward campaign and to audit dependencies carefully. Registry maintainers and npm administrators should continue to identify and remove such spam packages to protect the ecosystem.

Summary

The bambang-semur92-sluey npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (such as auto.js and autopublish.js) that automate the creation and publication of numerous 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 contributes to npm registry pollution with spam packages.
