Apple quietly drops iOS jailbreak detection API

By , Network World |  Mobile & Wireless, Axios Sytems, iphone jailbreak

MDM vendors such as Good Technology, MobileIron and Sybase all claim to be able to detect jailbroken iOS devices without the disabled Apple API. Typically, their on-device apps, in conjunction with the server, run a series of checks or try to do things that are forbidden by Apple, such as accessing certain underlying OS primitives. If the app can take these actions, it reports back that the device is jailbroken, and then can block or restrict access to the corporate network.

These techniques are not foolproof, cautions Intrepidus' Jeremy Allen.

"These methods cannot be relied upon with a high degree of confidence, but they would certainly catch many who jailbreak, just not all of them," he says. "I see it as a useful tool, but not an all-encompassing solution."

Allen strongly encourages enterprises to take a multi-layered approach and be realistic about the risks. "I always stress, heavily, [the importance of] educating users about the risks of jailbreaking," he says. "I feel that organizations must outline, in formal policy, that jailbreaking is not permitted. Many users are simply unaware of the risks associated with operating a jailbroken device."

Given the ongoing ingenuity of hackers, enterprises have to be plan accordingly, Allen warns. "For the users that still engage in jailbreaking, with full knowledge of the risks and detection mechanisms, there is little recourse to finding them," he says.
