stacksmashing: A Hacker’s Guide to Lightning and JTAG in iPhone

Duration: 20min 12sec Type: Presentation (lecture) Playlist: 9 of 146 in Defcon
A DEF CON 30 talk exploring the hidden capabilities of the iPhone’s Lightning port. Beyond charging, it can expose service interfaces such as a serial console and even CPU debugging via JTAG.

The speaker explains the Lightning architecture, the service cables used for device diagnostics, and how low-level data communication works.

The talk also introduces an open and affordable tool — the Tamarin cable — which allows researchers to explore the Lightning interface, send commands, and access iPhone debugging features.
