Description
The npm package basic_chinchilla_z3n is part of a malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts that automatically generate and publish derivative packages with randomized names to inflate developer reputation scores. The payload modifies package.json files to remove private flags, alters version numbers, and generates random Indonesian-themed or English package names. This activity results in continuous republishing of variants, polluting the npm registry.
