The npm package bayu-jengkol85-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 to inflate developer reputation scores for token rewards. It modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants, polluting the npm registry.
