Does the attacker have to be near the victim?Īfter an iOS user has trusted a computer, at any time in the future that computer can be used to carry out attacks when the device is either connected via USB, or when the iOS device and the computer are connected to the same Wi-Fi wireless network. Unlike MacBooks and iMacs, iOS devices do not include camera-in-use indicator lights, so a victim would have no way of knowing that they were being spied upon in this manner. Krause shows how a hijacked camera can reveal a user’s emotion. It’s also possible for repackaged apps to do things like secretly take pictures of you using your front-facing camera, record audio using your microphone, and more iOS developer Felix Krause shared examples of similar behavior in October 2017. If an attacker were to replace your iPhone’s secure messaging app with a malicious repackaged version, all of your “secure” messages could be siphoned off and made available for the attacker-before they were ever encrypted in the first place. Many people use secure messaging apps, like Signal, for instance, to transmit messages that only the recipient can decrypt. Imagine, if you will, a couple of scenarios in which replacing an app with a compromised version could be a serious security and privacy concern. Is this the real Facebook app or a maliciously modified version? In their demonstration, it took less than a second for the iPhone’s legitimate Facebook app to get replaced with a repackaged version.īy repackaging an app, an attacker can insert functionality of their choosing, including functions only available via private APIs that Apple doesn’t allow to be used in App Store apps. One of the most concerning attacks enabled by trustjacking that Sharabani and Iarchy demonstrated was the ability to replace an iOS app with a malicious version that had an identical icon, which appeared in the same location as the original. Remotely observing iOS is a modern version of shoulder surfing.

Given that iOS briefly shows the most recently typed character in password fields, it’s possible for an attacker to watch a victim type their banking or other passwords. This is effectively a clever, modern way to conduct a “shoulder surfing” attack without having to be in the same room as the victim. The researchers also demonstrated how an attacker could live-stream continuous screenshots from the device, effectively simulating a live video feed of what was on the iPhone’s screen.

On the MacBook, Iarchy issued a command to Sharabani’s iPhone to back up its data over Wi-Fi, which is made possible by an iOS feature called iTunes Wi-Fi Sync, which works on both macOS and Windows hosts. Sometime before the presentation, Sharabani had previously connected his iPhone X to Iarchy’s MacBook and tapped “Trust” in a dialog box on the iPhone-something many people do when they connect their iPhone to a computer.ĭuring the presentation, Sharabani used his iPhone X to take a selfie with Iarchy, after which he sent a text message to their company’s CEO. The security researchers, Adi Sharabani and Roy Iarchy, presented a live demonstration of the attack. What exactly is the “trustjacking” attack?

What exactly is the “trustjacking” attack?.On Wednesday morning at RSA Conference 2018, two security researchers gave a presentation that has massive security and privacy implications for users of all devices that run Apple’s iOS operating system: iPhone, iPad, and iPod touch. Have you ever plugged in your iPhone to a USB port and tapped “Trust” on your screen? You might have unknowingly given an attacker permanent access to your device-even wirelessly, and potentially even remotely.
