Why Do We Care About Jailbreaking at Duo?Īt Duo, we give administrators insight into the health of devices used to access corporate resources. The value of an iOS exploit on the private market is easily several hundred thousand dollars, and can also exceed $1,000,000 under the right criteria (remote, persistent and zero-click), making a private sale a much more lucrative option than releasing it publicly. As Apple hardens the security of its iOS devices, exploiting them becomes significantly harder.
The jailbreak scene has shrunk significantly since the release of the original iPhone.
Since then, Apple and jailbreak developers have been in a cat-and-mouse game, with Apple patching vulnerabilities while developers and researchers attempt to find new ones. Hotz’s original exploit required a small hardware modification to the device, but software-only jailbreaks were released soon after. A carrier-unlock is not the same as a jailbreak, but in this case, jailbreaking the device was a prerequisite. The first iPhone was released in June 2007, and in August 2007, George Hotz became the first person to carrier-unlock the iPhone. Regardless of the user’s rationale, the presence of a jailbreak on a device means that the security model of the OS can no longer be adequately trusted or reasoned about by an application. In short, people jailbreak their devices for many reasons, ranging from research to personal philosophy. This means that in order to meaningfully explore the system, researchers are forced to subvert the device’s security model (i.e., by jailbreaking). Gal Beniamini from Google’s Project Zero says:Īpple does not provide a “developer-mode” iPhone, nor is there a mechanism to selectively bypass the security model. iOS kernel security research is significantly easier with root-level access to the device. Jailbroken devices are also excellent tools for security researchers.
After jailbreaking, users can install applications and tweaks via unofficial app stores. To run applications that are not available in the App Store or make modifications to the behavior of the operating system, a “jailbreak” is required-effectively, an exploit that allows the user to gain administrative access to the iOS device.
