Malicious code in rrs (PyPI)

Details

**Severity:** Critical

**Affected versions:** `= 0.4.105`

## Source: amazon-inspector (78c488c5d20c788e88c2d4f0a0cb1eb03317bc71edb05964adad62241fd1295e)
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.
