The npm package 'nurul-peyek91-riris' is part of a malicious campaign linked to the tea.xyz token reward scheme. It contains autopublish scripts that automatically generate and publish numerous derivative packages with randomized Indonesian-themed names. These actions aim to manipulate developer reputation scores by flooding the npm registry with variants. The malicious payload modifies package.json files to remove private flags and alter version numbers, facilitating continuous republishing of these variants.
