: Hardware-level hacking often involves mirroring audio data from specific extensions directly on the board to a recording device.

: Advanced attackers can target the voltage regulators on a PBX motherboard to physically "brick" or destroy the hardware, causing significant business disruption.

Most embedded PBX motherboards include debug interfaces left enabled by the manufacturer.

Security researchers often target the motherboard to extract the firmware controlling the PBX.

From a defensive perspective, understanding the hardware layer is crucial for securing critical infrastructure.
