Description
The autonomous_fish_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 Indonesian-themed names. These scripts modify package.json files to remove private flags and alter version numbers, enabling continuous republishing of variants. This activity pollutes the npm registry and inflates developer reputation scores fraudulently.
