Description

The npm package dewi-tapai4-riris contains malicious code linked to the tea.xyz token reward campaign, which flooded npm with over 15,000 spam packages in 2024. The package includes 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 inflate developer reputation scores and pollute the npm registry.

Impact

This malicious package pollutes the npm registry with spam packages, potentially misleading developers and automated systems that rely on package metadata and reputation. It artificially inflates developer reputation scores within the tea protocol token reward system, undermining trust in the ecosystem. There is no indication of direct exploitation or compromise of end-user systems beyond registry pollution and reputation manipulation.

Defensive guidance

Users and maintainers should avoid installing or depending on the dewi-tapai4-riris package and other related spam packages from the tea.xyz campaign. Registry maintainers and security teams should consider removing or blocking these packages to prevent further pollution. Monitoring for similar autopublish scripts in npm packages can help identify and mitigate ongoing abuse.

Summary

The dewi-tapai4-riris npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of numerous derivative packages with randomized names. The payload manipulates package.json by removing private flags and changing version numbers to enable repeated publication. This behavior aims to inflate developer reputation scores fraudulently and pollute the npm ecosystem with spam packages.
