The npm package 'joni-kupang15-sukiwir' 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 malicious payload modifies package.json files to remove private flags and alters version numbers to continuously republish variants. This activity aims to inflate developer reputation scores and pollutes the npm registry with numerous fraudulent packages.
