Description
The npm package umi-saguer52-ruro contains malicious code linked to the tea.xyz token reward campaign that flooded npm with over 15,000 spam packages in 2024. The malicious payload includes autopublish scripts that automatically generate and publish derivative packages with randomized names. These scripts modify package.json files to remove private flags, alter version numbers, and create Indonesian-themed package names to repeatedly republish variants, polluting the npm registry and inflating developer reputation scores for token rewards.
