Description
The faint_fish_z3n npm package is part of a token reward campaign that floods the npm registry with derivative packages. It contains malicious autopublish scripts that automatically generate and publish new package variants with randomized Indonesian-themed names. These scripts modify package.json files to remove private flags and change version numbers, enabling continuous republishing to inflate developer reputation scores and pollute the npm ecosystem.
