Description
The acute_louse_z3n npm package is part of a malicious campaign linked to tea.xyz token rewards. It contains autopublish scripts that automatically generate and publish numerous derivative packages with randomized names. These actions aim to inflate developer reputation scores by continuously republishing variants, polluting the npm registry with malicious payloads that modify package metadata.
