Description
The changing_marmot_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 generates random Indonesian-themed package names. This activity results in continuous republishing of variants, polluting the npm registry.
