M1: Improper Platform Usage
The misuse of a platform feature or failure to use platform security controls. It might include Android intents, platform permissions, misuse of TouchID, the Keychain, or some other security control that is part of the mobile operating system.
M3: Insecure Communication
When designing a mobile apps, data is commonly exchanged in a client-server mode. When the solution transmits its data, it must traverse the mobile device’s carrier network and the internet. Threat agents might exploit vulnerabilities to intercept sensitive information while it’s traveling across the wire.
M5: Insufficient Cryptography
Threat agents include the following: anyone with physical access to data that has been encrypted improperly, or mobile malware acting on an adversary’s behalf.
M6: Insecure Authorization
Once the adversary understands how the authentication scheme is vulnerable, they fake or bypass authentication by submitting service requests to the mobile app’s backend server and bypass any direct interaction with the mobile app. This submission process is typically done via mobile malware within the device or botnets owned by the attacker.
M7: Client Code Quality
Threat Agents include entities that can pass untrusted inputs to method calls made within mobile code. These types of issues are not necessarily security issues in and of themselves but lead to security vulnerabilities. For example, buffer overflows within older versions of Safari (a poor code quality vulnerability) led to high risk drive-by Jailbreak attacks. Poor code-quality issues are typically exploited via malware or phishing scams.
M9: Reverse Engineering
An attacker will typically download the targeted app from an app store and analyze it within their own local environment using a suite of different tools.
M10: Extraneous Functionality
Typically, an attacker seeks to understand extraneous functionality within a mobile app in order to discover hidden functionality in in backend systems. The attacker will typically exploit extraneous functionality directly from their own systems without any involvement by end-users.
