The chubby_blackbird_z3n npm package is part of a malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts that automatically generate and publish numerous derivative packages with randomized names, aiming to inflate developer reputation scores. The payload modifies package.json files by removing private flags, altering version numbers, and creating Indonesian-themed or English package names. This activity results in continuous republishing of variants, polluting the npm registry.
