The npm package udin-jus45-ruro 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 automatically generate and publish derivative packages with randomized names. The malicious payload modifies package metadata to remove private flags, alter version numbers, and continuously republish variants, thereby polluting the npm registry and inflating developer reputation scores for token rewards.
