Background
ucok-poke7 is an npm package that has been identified as part of a malicious campaign targeting the npm registry. This package is associated with the tea.xyz token reward initiative, which aims to inflate developer reputation scores through the automatic generation and publication of derivative packages. The malicious nature of ucok-poke7 lies in its ability to modify its own package.json file, thereby compromising the integrity of the npm ecosystem.
