The npm package bambang-bakso31-sukiwir contains malicious code linked to a large-scale spam campaign involving over 15,000 packages. These packages include autopublish scripts that automatically generate and publish derivative packages with randomized Indonesian-themed names. The malicious payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants to manipulate developer reputation scores for the tea.xyz token reward system, thereby polluting the npm registry.
