Description
The muddy_meadowlark_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. The payload modifies package.json files to remove private flags, alters version numbers, and creates Indonesian-themed package names. This behavior results in continuous republishing of variants, polluting the npm registry.
