The npm package bayu-brongkos11-breki 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 generate and publish numerous derivative packages with randomized Indonesian-themed names. The malicious payload alters package.json files by removing private flags and changing version numbers, enabling continuous republishing of variants to inflate developer reputation scores and pollute the npm registry.
