The npm package erwin-tahutek57-riris contains malicious code linked to a large-scale spam campaign flooding npm with over 15,000 packages in 2024. These packages include autopublish scripts that automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for the tea.xyz token reward system. The malicious payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants, polluting the npm registry.
