The npm package fajar-kacang77-riris contains malicious code linked to a large-scale spam campaign associated with 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 names. The malicious payload alters package.json files by removing private flags, changing version numbers, and generating random Indonesian-themed package names, resulting in continuous republishing of variants that pollute the npm registry.
