On its own, detecting rooted/jailbroken devices doesn’t bring a lot of security. There are various ways to implement jailbreak and rooting detection, however, it should be seen only as a ‘helper’ countermeasure. If a mobile banking/payment application can perform operations only possible for a root user, then obviously, a rooted device is detected. Same as with iOS, a root detector can try to perform several operations outside of its normal rights and check whether they can complete or not. One can also check for the following files īuild tags that do not contain ‘standard’ values such as ‘ test’, etc., indicate a rooted device.

The presence of several packages is a sign of a rooted Android device, for example: It gathers information from various sources and can allow the detection of a rooted device. SafetyNet is a complex system using billions of devices that are play-enabled. It can detect an unlocked bootloader, which is the obvious sign of a rooted device. SafetyNet is the ‘official’ rooting detection package for Android. Rooting detection will follow approximately the same technique as with iOS.

An incorrect code signature will always be validated with a broken device, while an unbroken device will correctly report a bad signature. It’s possible to detect such a state by asking iOS to verify an incorrect code signature. Here are some typical return values from such operating system functions and how they indicate the presence of an ios jailbroken device or not:Ī broken kernel is a sign that a jailbreak operation was performed.
Jailbreak detectors may call the system( ) function and other similar functions. Jailbreaking also changes partitions, so it must create several system symbolic links that also can be detected. For instance, the directory /private should not be writable by an application in iOS. File PermissionsĪ jailbroken device allows users to reach and modify files or directories outside their sandbox, thus a successful modification of such files is the sign of jailbreak. So, finding Cydia on a device equals the fact that the device is jailbroken. Here is a list of popular binaries reached through the Cydia platform:Īs the developers of the application mention, Cydia needs a jailbroken device to run. Cydia is a package manager that locates and installs unauthorized iOS binaries designed and developed for jailbroken devices. One very straightforward method to detect a jailbroken device is to check for the presence of Cydia. Jailbreak Detection Techniques (iOS) Cydia & File-Based Checks In what follows, we will see what corresponding techniques are used for jailbreak and rooting detection. To protect against the risks posed by rooted/jailbroken devices, banking apps or other apps with sensitive data need the ability to detect such conditions and to respond to them by preventing the execution or restricting the functionalities of the application. Less obvious is that malware can root the operating system themselves and therefore a rooted device can be a sign of infection.
This means that malware will also be able to do things it would never be able to do in a non-modified device and may be hard or close to impossible to remove.Ī root malware for instance can use a library like Xposed on Android to intercept the calls to the SSL libraries from a banking or payment application and read the confidential data transferred to financial institutions.
In a rooted or jailbroken device, applications can have much more privileges than they should have. While they indeed may, at first glance, give more freedom to the users, rooted or jailbroken devices create vulnerabilities for the mobile applications and, as a consequence, jeopardize mobile and payment applications running on such modified systems. Therefore, rooted or jailbroken phones present important security risks for a mobile banking/payment application. Restricting the user’s rights is a very important and natural default security mechanism in both of these operating systems.

The process of removing such restrictions, which is not supported by either Google or Apple, is named rooting and jailbreaking, respectively for Android and iOS. Unlike other operating systems like Windows, Linux, or OSX, both Android and iOS operating systems are usually shipped with built-in user rights restrictions.
