The npm package erwin-dradag33-riris contains malicious code linked to the tea.xyz token reward campaign, which flooded npm with over 15,000 spam packages in 2024. These packages use autopublish scripts to automatically generate and publish derivative packages with randomized names. The malicious payload modifies package.json files to remove private flags, alters version numbers, and generates random Indonesian-themed package names to continuously republish variants, polluting the npm registry.
