Description
The cold_hookworm_z3n npm package is part of a malicious campaign linked to the tea.xyz token reward system. 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 artificially inflates developer reputation scores within the tea protocol token rewards ecosystem.
