Description
The advisory_moose_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 payload modifies package.json files to remove private flags, changes version numbers, and continuously republishes variants, polluting the npm registry with numerous malicious or spam packages.
