The magnetic_mastodon_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, aiming to inflate developer reputation scores. The malicious payload modifies package.json files by removing private flags, changing version numbers, and generating random Indonesian-themed or English package names. This behavior results in continuous republishing of variants, polluting the npm registry.
