Description
The npm package 'cooing_gerbil_z3n' is part of a token reward campaign flooding the npm registry with malicious packages. These packages contain autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The malicious payload modifies package.json files to remove private flags and change version numbers, enabling continuous republishing of variants. This activity aims to inflate developer reputation scores for the tea.xyz token rewards and pollutes the npm ecosystem.
