The npm package cindy-serabi55-riris contains malicious code linked to a large-scale spam campaign involving over 15,000 packages in 2024. These packages include autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The malicious payload manipulates package.json files by removing private flags and altering version numbers, enabling continuous republishing of variants to pollute the npm registry and inflate developer reputation scores for the tea.xyz token reward campaign.
