Threat Score
A zero-day in AnyCubic Kobra 2/Pro/Plus/Max printers' cloud/MQTT service allowed attackers to connect using valid credentials and queue a G-code file that printed a warning message on affected printers; multiple users reported the activity worldwide. Researchers claim they repeatedly attempted to notify AnyCubic before exploiting the flaw to warn owners; AnyCubic released firmware on March 5 to strengthen MQTT authorization and provided mitigation steps including disabling Wi‑Fi.
