Description
The npm package mighty_squid_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 names. The payload modifies package.json files to remove private flags, alter version numbers, and create Indonesian-themed package names, continuously republishing variants to pollute the npm registry.
