An adversary, through a previously installed malicious application, registers for a URL scheme intended for a target application that has not been installed. Thereafter, messages intended for the target application are handled by the malicious application. Upon receiving a message, the malicious application displays a screen that mimics the target application, thereby convincing the user to enter sensitive information. This type of attack is most often used to obtain sensitive information (e.g., credentials) from the user as they think that they are interacting with the intended target application.
The table(s) below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.

Meta Attack Pattern - A meta level attack pattern in CAPEC is a decidedly abstract characterization of a specific methodology or technique used in an attack. A meta attack pattern is often void of a specific technology or implementation and is meant to provide an understanding of a high level approach. A meta level attack pattern is a generalization of related group of standard level attack patterns. Meta level attack patterns are particularly useful for architecture and design level threat modeling exercises.
The only known mitigation to this attack is to avoid installing the malicious application on the device. Applications usually have to declare the schemes they wish to register, so detecting this during a review is feasible.
