Deck Mate 2's firmware update mechanism accepts packages without cryptographic signature verification, encrypts them with a single hard-coded AES key shared across devices, and uses a truncated HMAC for integrity validation. Attackers with access to the update interface - typically via the unit's USB update port - can craft or modify firmware packages to execute arbitrary code as root, allowing persistent compromise of the device's integrity and deck randomization process. Physical or on-premises access remains the most likely attack path, though network-exposed or telemetry-enabled deployment
