Description

The npm package umi-rawon80-sluey was identified as containing malicious code as part of a large-scale spam campaign linked to tea.xyz token rewards. This campaign flooded the npm registry with over 15,000 packages that include autopublish scripts to 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 within the tea protocol token ecosystem.

Impact

The malicious code enables continuous automatic republishing of derivative packages, which pollutes the npm registry with spam packages. This can degrade the quality and trustworthiness of the npm ecosystem and artificially inflate developer reputation scores tied to the tea protocol token rewards. There is no indication of direct exploitation or compromise of user systems beyond registry pollution and reputation manipulation.

Defensive guidance

Users and maintainers should avoid installing or using the umi-rawon80-sluey package and related packages from the tea.xyz token reward campaign. Registry maintainers should consider removing these spam packages to preserve ecosystem integrity. Monitoring for and blocking autopublish scripts in packages can help mitigate similar threats.

Summary

The umi-rawon80-sluey npm package is part of a widespread malicious campaign involving over 15,000 spam packages associated with the tea.xyz token reward system. These packages contain autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of derivative packages with randomized names. The malicious code manipulates package.json by removing private flags and changing version numbers to enable continuous republishing. This behavior aims to pollute the npm registry and artificially boost developer reputation scores to exploit the tea protocol token rewards.
