Description

The npm package bayu-kue99-riris contains malicious code linked to a large-scale spam campaign associated with the tea.xyz token reward system. This campaign involves over 15,000 spam packages that use autopublish scripts to generate and publish numerous derivative packages with randomized Indonesian-themed names. The malicious payload manipulates package metadata to remove private flags and increment version numbers, enabling continuous republishing and registry pollution.

Impact

This malicious package undermines the integrity of the npm registry by flooding it with spam packages that artificially inflate developer reputation scores for the tea protocol token rewards. It can cause ecosystem pollution, complicate package management, and potentially mislead users relying on package metadata. There is no indication of direct exploitation or compromise of user systems beyond registry pollution.

Defensive guidance

Users and maintainers should avoid installing bayu-kue99-riris and related packages from the tea.xyz token reward campaign. Registry maintainers should consider removing these spam packages and enhancing detection mechanisms to prevent autopublish spam. Developers should verify package authenticity before installation.

Summary

The bayu-kue99-riris npm package is part of a widespread malicious campaign flooding the npm registry with spam packages to exploit the tea.xyz token reward mechanism. It includes autopublish scripts (e.g., auto.js, autopublish.js) that automatically create and publish derivative packages with randomized names. The payload modifies package.json files by removing private flags and altering version numbers, facilitating repeated republishing of variants. This behavior inflates developer reputation scores fraudulently and pollutes the npm ecosystem.
