"Apple's Shift from Thunderbolt to USB-C Sparks Hacking Wave at 37C3"
Thomas Roth, known as Ghidraninja, who previously developed a debugging tool for Apple's Lightning port, has shifted his focus to USB-C after Apple's transition to the connector for their new phones. He discovered that the iPhone 15 uses vendor-defined messages (VDM) in USB-PD for various features and managed to enable a serial port and JTAG, although JTAG is currently locked on production devices. Roth also identified signals for the System Power Management Interface (SPMI) and is working on an open-source SPMI plugin. His work represents the early stages of hacking into the new iPhone's capabilities via USB-C.
