Apple iPhone USB-C Hacked – What Users Need To Know

Ripples have been sent through the tech community after recent revelations about a hack targeting Apple’s custom ACE3 USB-C controller. The hack, unveiled by security researcher Thomas Roth at the 38th Chaos Communication Congress (38C3), highlights potential vulnerabilities in Apple’s iPhone 15 series, the first to include USB-C.

To get code execution on the ACE3 controller, Roth used advanced techniques such as reverse engineering, side channel analysis, and electromagnetic fault injection to bypass Apple’s protections. This gave him the opportunity to dump the controller’s firmware and provided a basis for further investigation into possible vulnerabilities. This hack is big, but Roth said it doesn’t currently pose a direct threat to everyday users because the attack is too complex to be used on a mass scale.

Apple’s response has been measured. The company acknowledged the research but said the attack’s real-world risk was minimal because of its complexity. But Roth’s work could spur additional research that might reveal more serious vulnerabilities.

But Mike Grover, inventor of the O.MG Cable hacking tool, lauded Roth’s research but cautioned that attack complexity could be reduced over time. Meanwhile, cybersecurity consultant Adam Pilton warned that the firmware data could be misused, likening it to a ‘blueprint for a bank.’

It’s also reignited discussion about juice jacking, an attack that would take advantage of public charging ports to compromise devices. Although rarely reported in real-world scenarios, the threat is important to remind people to use personal chargers or USB data blockers in public places.

iPhone users shouldn’t panic, but they should be aware of these vulnerabilities. The ACE3 hack is a reminder that even the most secure devices can be challenged by determined researchers. The best defense for now is to stay informed and practice basic cybersecurity hygiene, like not using untrusted charging ports.
