The security of Apple’s Lightning connector has been compromised by a team of hackers, reported Apple jailbreak site iDownloadblog.

The Lightning connector is a power connector and a proprietary bus that is present in all modern iPhones, iPads and iPod Touch devices.

The vulnerability will grant hackers access to serial kernel debugging and will also makes it easy to debug iBoot level exploits. The availability of Lightning serial access means more hackers will be able to find exploits for future jailbreaks.

iOS hacks were previously developed on older 30-pin iDevices but the new hack could be created directly on Lightning-equipped kit.

A user named @key2fr on Ramtin-Amin.fr showed how the person hacked and built a connector for the units.

The user also promised to build a batch of the Lightning debug cables next week which will give easy access to engineers who are unable to acquire official C10C serial connectors under Apple’s MFi programme.

The Register cited Tool box HackADay as saying that it was the "first step" to "totally owning an iDevice".

"This is the key to the castle, and being able to get through this chip means we can now own our iDevices."
