Description

The irma-gembus99-ruro npm package is part of a malicious campaign linked to the tea.xyz token reward system. It contains autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags and change version numbers, enabling continuous republishing of variants. This behavior pollutes the npm registry and inflates developer reputation scores illegitimately.

Impact

The malicious package causes pollution of the npm registry by generating numerous derivative packages with randomized names and altered metadata. This undermines the integrity of the npm ecosystem and can mislead users and automated systems relying on package metadata. It also artificially inflates developer reputation scores within the tea.xyz token reward campaign, potentially enabling abuse of the token reward system.

Defensive guidance

Users and maintainers should avoid installing or trusting packages related to the tea.xyz token reward campaign, including irma-gembus99-ruro and its derivatives. Registry maintainers should consider removing or blocking these packages to prevent further pollution. Monitoring for packages exhibiting autopublish behavior and randomized naming patterns can help identify and mitigate this threat.

Summary

This threat involves the irma-gembus99-ruro npm package, which is associated with the tea.xyz token reward campaign that flooded the npm ecosystem. The package includes autopublish scripts (such as auto.js and autopublish.js variants) that automate the creation and publication of derivative packages with randomized names. The malicious code alters package.json by removing private flags and modifying version numbers to facilitate repeated republishing. This results in a polluted npm registry and artificially inflated developer reputations within the tea protocol token system.
