Description

The npm package 'mahesa-rangginang29-sukiwir' is part of a campaign linked to tea.xyz token rewards that floods the npm registry with malicious packages. These packages contain 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 within the tea protocol token ecosystem.

Impact

The malicious package pollutes the npm registry by generating numerous derivative packages with randomized names, which can degrade the quality and trustworthiness of the npm ecosystem. It manipulates package metadata to bypass private package restrictions and repeatedly publishes variants, potentially misleading users and automated systems that rely on package reputation. There is no indication of direct exploitation or compromise of end-user systems beyond registry pollution and reputation inflation.

Defensive guidance

Users and maintainers should avoid installing or trusting packages associated with the tea.xyz token reward campaign, including 'mahesa-rangginang29-sukiwir'. Registry maintainers should consider removing or blocking these malicious packages to prevent further pollution. Monitoring for similar autopublish scripts in npm packages can help identify and mitigate this threat.

Summary

This threat involves the npm package 'mahesa-rangginang29-sukiwir', which is associated with the tea.xyz token reward campaign. The package includes autopublish scripts (such as auto.js and autopublish3.js) that automate the creation and publication of 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 results in pollution of the npm registry and artificially inflates developer reputation scores tied to the tea protocol token rewards.
