Their `preinstall` script runs `node index.js`, which reads the OS username and hostname and sends them in a DNS lookup of `msrc-poc.<user>.<hostname>.dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun`, an out-of-band interaction collector; `index.js` is also the package entry point, so the lookup repeats whenever the package is required. Any machine that installed one of these versions has disclosed its username and hostname to a third party. The earlier `0.0.0-stage` version is an inert placeholder and is not affected.\n\n---\n_-= Per source details.
