On `npm install`, the package's postinstall script runs `node -e` to fetch the installer's public IP from api.ipify.org, execute `id || ver && whoami && hostname`, and collect hostname, cwd, and USERDOMAIN/COMPANY environment variables. The bundle is POSTed to a hardcoded interactsh subdomain at lszakfghwnvxspyfcmaabd1css99rnq3w.oast.fun. The package has no legitimate function: description is 'xxx', main file index.js is 0 bytes, and the only behavior is the install-time beacon. Combined with the unusual name shape, this matches dependency-confusion reconnaissance campaigns that probe corporate networks via Project Discovery's interactsh out-of-band service.
