The Risks of Reverse Engineering & How to Prevent them
In the past few years, a
massive number of apps have been developed every single year. Moreover, the
number of mobile phone users has also increased exponentially. From grocery
shopping to booking a cab - there is an app for everything. And the convenience
that apps offer attracts users around the world. However, with the rise in the
number of apps and downloads, there has also been an increase in the number of mobile
app security risks.
These risks are harmful to
users as well as businesses. And hence, it is of utmost importance for
developers to acquaint themselves with these risks, so that they can be
prevented. One way of becoming aware of these risks is by learning more about
the OWASP
mobile top 10 security risks. It is a list of app
security risks that have been curated by experts around the globe. It is a free
guide created for developers so that they integrate countermeasures into their
apps during the developmental stage itself.
The
Risks of Reverse Engineering and tips to prevent them
Reverse Engineering of code
is one of the most common ways of exploiting app security. Hackers make use of
easily available, external binary inspection tools to analyze the app’s
original code and the way it links with the server. The reverse engineering app security risks are as follows:
Dynamic
Inspection
Certain languages tend to be
much more susceptible to reverse engineering, given that they allow for dynamic
inspection during runtime. Thus, reverse engineering can affect the security of
the servers as well as the data that might be stored on mobile devices. It also
impacts the server’s ability to detect rooted devices.
Code Theft
Reverse engineering allows
even competitors to view the app’s functionality entirely and even copy some of
these features. This helps them in reducing the cost of developing any new
code.
Premium
Features
This technique is used by
adversaries to bypass the authentication process and gain access to the premium
features. Thus, the cost of developing new code is reduced stealthily.
Practices that will help you
in avoiding reverse engineering are as follows:
Code
Obfuscation
The process of code
obfuscation should target specific segments of the source
code as well as the string tables and methods. However, this should be done
while ensuring that the code performance is not compromised. The developer must
also ensure that the level of the obfuscation they employ is not easily
reversed with the help of deobfuscation tools.
Utilize Similar
Tools
This might sound
antithetical but the best way of securing your app against the risks of reverse
engineering is to make use of the same tools that hackers make use of. Given
that these tools can easily analyze the control flow part, cryptographic
constants, interactions with servers, etc., that the code can be
compromised.
Conclusion
Apart from the aforementioned tips, you can also make use of C and C++ languages for avoiding reverse engineering. Alternatively, making use of Java Native Interface can also be helpful. Making use of these safety measures will help you in ensuring that your app is truly secure.
