Description

The npm package fajar-jamblang51-sukiwir contains malicious code linked to the tea.xyz token reward campaign that 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 to inflate developer reputation scores for token rewards. The malicious payload modifies package.json files by removing private flags, changing version numbers, and continuously republishing variants, thereby polluting the npm registry.

Impact

This malicious package contributes to registry pollution by flooding npm with spam packages that manipulate metadata to bypass restrictions. While no direct exploit or code execution impact is described, the campaign undermines the integrity of the npm ecosystem and can mislead developers relying on package reputation metrics. There is no evidence of active exploitation beyond the automated publication of spam packages.

Defensive guidance

Users and maintainers should avoid installing or trusting packages associated with this campaign. Registry maintainers should continue to identify and remove such spam packages to preserve ecosystem integrity.

Summary

The fajar-jamblang51-sukiwir npm package is part of a large-scale malicious campaign associated with tea.xyz token rewards. It contains autopublish scripts (such as auto.js and autopublish.js variants) that automate the creation and publication of numerous derivative packages with randomized names. These scripts manipulate package metadata by removing privacy flags and altering version numbers to enable repeated publication. The campaign's goal is to artificially inflate developer reputation scores by flooding the npm registry with spam packages, causing registry pollution and potential trust issues for npm users.
