Data from Local System
Sensitive data can be collected from local system sources, such as the file system or databases of information residing on the system.
Local system data includes information stored by the operating system. Access to local system data often requires escalated privileges (e.g. root access). Examples of local system data include authentication tokens, the device keyboard cache, Wi-Fi passwords, and photos.
GolfSpy can collect local accounts on the device, pictures, bookmarks/histories of the default browser, and files stored on the SD card. GolfSpy can list image, audio, video, and other files stored on the device. GolfSpy can copy arbitrary files from the device.
Monokle can retrieve the salt used when storing the user’s password, aiding an adversary in computing the user’s plaintext password/PIN from the stored password hash. Monokle can also capture the user’s dictionary, user-defined shortcuts, and browser history, enabling profiling of the user and their activities.
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
Accessing data from the local system can be difficult to detect, and therefore enterprises may be better served focusing on detection at other stages of adversarial behavior.
