Mobile app developers must take into account a whole host of new risks that relate to hosting code in an uncontrolled environment. If you are hosting code in an untrustworthy environment, you are susceptible to the risk that an adversary will reverse engineer and modify your code via binary attacks [[[#ReferenceItem1|1]]] [[[#ReferenceItem2|2]]] [[[#ReferenceItem3|3]]] [[[#ReferenceItem4|4]]].

[[File:MainProjectIcon.png|30px|link=https://www.owasp.org/index.php/OWASP_Reverse_Engineering_and_Code_Modification_Prevention_Project]] This content is part of a much bigger set of principles defined within the [https://www.owasp.org/index.php/Architectural_Principles_That_Prevent_Code_Modification_or_Reverse_Engineering Architectural Principles That Prevent Code Modification or Reverse Engineering] project.

= Description =
Integrity controls within applications must be applied using a defense-in-depth strategy within the application binary. A network of integrity controls should protect each other as well as the underlying application. This integrity control layering strategy makes integrity vulnerabilities extraordinarily difficult to exploit and thus unlikely to occur.

= Examples =
Checksum controls should protect other checksum controls that verify the integrity of the application. This makes it a tedious and difficult task for an attacker to tamper with the integrity verification mechanism.

An attacker could gain access to the development infrastructure of the bank and infest the application with malware causing a massive infection for all of the application’s users.”''
