Description
The alleged_silverfish_z3n npm package is part of a token reward campaign flooding the npm registry with malicious packages. These packages contain autopublish scripts that automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for the tea.xyz token rewards. The malicious payload modifies package.json files to remove private flags, alters version numbers, and continuously republishes variants with Indonesian-themed names, polluting the npm registry.
