Description

The controlled_landfowl_z3n npm package is part of a malicious campaign linked to tea.xyz token rewards. 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, change version numbers, and continuously republish variants. This activity pollutes the npm registry and inflates developer reputation scores fraudulently.

Impact

The malicious package pollutes the npm registry with numerous derivative packages, potentially misleading developers and users relying on npm for legitimate packages. It artificially inflates developer reputation scores within the tea.xyz token reward system, undermining trust in the ecosystem. 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 trusting packages linked to the tea.xyz token reward campaign and monitor for suspicious autopublish scripts in npm packages. Registry maintainers may consider removing or blocking such packages to prevent further pollution.

Summary

This threat involves the controlled_landfowl_z3n npm package, which is associated with the tea.xyz token reward campaign. The package includes autopublish scripts (such as auto.js and autopublish.js) that automate the creation and publication of numerous derivative packages with randomized names. The malicious code alters package.json files by removing private flags and modifying version numbers, enabling repeated publication of variants. This behavior aims to flood the npm registry with these packages, artificially boosting developer reputation scores within the tea protocol token ecosystem.
