On launch of the rrs CLI, a background thread captures a full-screen screenshot via mss and POSTs the image together with hostname, username, OS/release, local IP, and timestamp to a hardcoded Discord webhook at https://discord.com/api/webhooks/1549807268294303860/... The upload runs unconditionally at startup, with no consent prompt and no user-configurable destination; the webhook is controlled by the package author and is not disclosed as a destination for screen contents. Separately, Network.start opens an MQTT connection to the public broker broker.hivemq.com:1883 and publishes a JSON identity record (id, hostname, username, os) to the shared topic rrs/v1/presence every 5 seconds, exposing installer host and user identifiers to any subscriber of that world-readable topic. Screen contents typically include private data, credentials, tokens, and messages visible on the desktop at the moment of capture.

The package automatically and silently exfiltrates screenshots to a hardcoded location.
