Description
The frequent_tuna_z3n npm package 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 malicious payload modifies package.json files to remove private flags, changes version numbers, and creates random Indonesian-themed or English package names. This activity results in continuous republishing of variants, polluting the npm registry.
