The npm package erwin-tapai13-riris contains malicious code as part of a large-scale spam campaign linked to the tea.xyz token reward system. This campaign involves over 15,000 spam packages that use autopublish scripts to automatically generate and publish derivative packages with randomized Indonesian-themed names. The malicious payload modifies package.json files to remove private flags, alter version numbers, and continuously republish variants, thereby polluting the npm registry and inflating developer reputation scores for token rewards.
