The npm package fitri-ikan49-ruro contains malicious code that is part of a large-scale spam campaign flooding the npm registry with 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.
