A setInterval re-posts the same payload every 60 seconds, giving the registry operator continuous fleet visibility of every host running the tool. Opt-out is only via an undocumented `PORTLOOP_REGISTRY=off` env var. Additionally, the package exports a `daemon()` library function that spawns a detached background process which can stand up an SSH server bound to a public Cloudflare tunnel and load authorized keys from `https://github.com/\u003cuser\u003e.keys` (index.js:124, index.js:686). A consuming package or a misconfigured caller invoking `require(\u0027portloop\u0027).daemon({ssh:true, github:\u0027someone\u0027})` results in a persistent remote-shell server on the host with attacker-controlled SSH keys, reachable from the public internet via the ephemeral tunnel. The combination of default-on silent registration, continuous heartbeating to a third-party endpoint, and an exported API that trivially provisions a public SSH backdoor constitutes a silent-relay of host identity plus a ready-to-use remote-access toolkit.\n",
