| Summary |
An adversary examines screenshot images created by iOS in an attempt to obtain sensitive information. This attack targets temporary screenshots created by the underlying OS while the application remains open in the background. |
| Prerequisites |
This type of an attack requires physical access to a device to either excavate the image files (potentially by leveraging a Jailbreak) or view the screenshots through the multitasking switcher (by double tapping the home button on the device). |
| Solutions | To mitigate this type of an attack, an application that may display sensitive information should clear the screen contents before a screenshot is taken. This can be accomplished by setting the key window's hidden property to YES. This code to hide the contents should be placed in both the applicationWillResignActive() and applicationDidEnterBackground() methods. |

Description

| CAPEC-545 |
An adversary who is authorized or has the ability to search known system resources, does so with the intention of gathering useful information. System resources include files, memory, and other aspects of the target system. In this pattern of attack, the adversary does not necessarily know what they are going to find when they start pulling data. This is different than CAPEC-150 where the adversary knows what they are looking for due to the common location. |
