Description

The npm package 'putra-klentik63-breki' 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, alters version numbers, and continuously republishes variants to pollute the npm registry.

Impact

The malicious payload enables automated generation and publication of numerous npm packages, which can lead to pollution of the npm registry and manipulation of developer reputation scores. This can degrade the integrity of the npm ecosystem and potentially mislead developers relying on package metadata. There is no indication of direct exploitation or active attacks beyond reputation inflation and registry pollution.

Defensive guidance

Users and maintainers should avoid using or trusting packages associated with this campaign. Registry maintainers should consider removing or blocking these malicious packages to prevent ecosystem pollution. Monitoring for packages exhibiting autopublish behavior and randomized naming patterns can help identify related threats.

Summary

This threat involves the 'putra-klentik63-breki' npm package, which is associated with the tea.xyz token reward campaign. The package includes malicious autopublish scripts (e.g., auto.js, autopublish.js) that automate the creation and publication of numerous derivative packages with randomized names. The malicious code modifies package.json by removing private flags and changing version numbers to enable continuous republishing. This behavior inflates developer reputation scores fraudulently and pollutes the npm ecosystem with numerous variants, potentially undermining trust in npm packages.
