Description
The npm package 'evil_barracuda_z3n' is part of a malicious campaign linked to the tea.xyz token reward scheme. It contains autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The payload modifies package.json files to remove private flags and increment version numbers, enabling continuous republishing. This behavior inflates developer reputation scores fraudulently and pollutes the npm registry with numerous variants.
