Description
The npm package 'disappointed_horse_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 Indonesian-themed names. The payload modifies package.json files to remove private flags and alter version numbers, enabling continuous republishing to pollute the npm registry and inflate developer reputation scores.
