The npm package udin-nasi49-riris 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 Indonesian-themed names. These scripts modify package.json files to remove private flags and change version numbers, enabling continuous republishing of variants to pollute the npm registry and inflate developer reputation scores for token rewards.
