The npm package umi-martabak49-sukiwir contains malicious code linked to the tea.xyz token reward campaign, which flooded npm with over 15,000 spam packages in 2024. The malicious code includes autopublish scripts that automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for the tea protocol token rewards. The payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants with Indonesian-themed package names, polluting the npm registry.
