Security researchers from Synacktiv successfully hacked the Tesla Wall Connector through its charging port in just 18 minutes, exposing critical vulnerabilities in the device’s firmware and communication protocols.
The Tesla Wall Connector and Its Architecture
The Tesla Wall Connector is an AC electric vehicle charger designed for residential, public, and semi-public installations.
Supporting both single-phase and three-phase power, it delivers up to 22 kW depending on the configuration.
The device connects to the owner’s Wi-Fi network for telemetry and remote control via the Tesla mobile application.
At its core, the Wall Connector Gen 3 consists of two main components: a connectivity card (AW-CU300) powered by a Marvell 88MW300 SoC (ARM Cortex-M4) for Wi-Fi and application logic, and an STM32 microcontroller for managing sensors, power metering, and relay control.
Communication between these chips occurs over UART, using Protocol Buffers (Protobuf) for serialization.
