Some proven ways to protect your app from reverse engineering


With technical advancements, it is exceptionally simple to break a portable application, particularly Android ones. The saltine can debilitate publicizing and might withdraw it from different confirmation administrations.

Some could wish to break the application (gadget, program, programming) to figure out the working and unique highlights of your application; either to make a preferable application over yours or just totally repeat it. This specific practice is known as Reverse Engineering and has a wide assortment of utilization in assembling and, surprisingly, in military speech.

How to prevent reverse engineering of mobile applications?

Android applications are generally defenseless against assault as the code isn’t delivered into machine code, leaving it inclined to extraction and figuring out. The weak code can then be utilized for an assortment of reasons, which could be overwhelming for any genuine versatile application business. If you want to know how to protect the apps from reverse engineering? Here are some good ways to follow. 

1. Save significant code lumps on the server:

One more approach to forestalling applications from picking apart is to eliminate the code from the application and move it to any web administration that is scrambled server-side language.

For example, assuming that an organization is having a one of a kind code or calculation for their application, they wouldn’t permit their code to be taken. They can forestall this by just moving their code or calculation and letting the information be handled on a distant server, from there on, utilizing the application to get to that information.

2. Use C / C ++ to write important code:

Code written in Java is easier to decompile than code written in C / C ++. Therefore, developers sometimes use NDK to write important pieces of their native code to .so files. In addition, they add files as a combo library. However, this code can be broken down into symbolic instruction language code, but the reverse engineering process in a large library can be cumbersome and time-consuming. 

3. Be careful when requesting SSL:

When interacting between a server and a device, developers use SSL to better secure their code.

There are several irrelevant methods available in the class that runs SSLSocketFactory. These irrelevant procedures accept all types of certificates; which makes the application vulnerable to moderate attack (MitM). This can lead to a loss of confidentiality of SSL / TSL data. An attacker could easily disconnect and gain valuable data by simply providing a self-signed certificate.

4. Avoid saving values ​​in raw format:

Using raw format is not recommended for storing values. Assuming that it is necessary to store user balance values ​​(in foreign currency), these values ​​must be written in an encoded form (for example, stored in an algorithm).

It is an open-source cross-platform tool written in Java that helps ensure the security of mobile applications. It is a command-line tool that minifies, optimizes, obfuscates, and even checks previous code. Let’s see how it works:

• Minify Method: Identify and remove unused mobile app class, field, method attributes.

• Optimization: Analyze and optimize bytecode from various methods.

• Confusion: classes, fields, and other methods are given short and meaningless names

The steps above make it difficult to redesign the app, which makes the codebase smaller, more efficient, and more complex.

5. Getting User accreditations:

It is prudent to tie down the client certifications to keep away from figuring out the application.

• The recurrence of looking for client accreditations in the portable application ought to be less. This will permit the applications to keep away from phishing assaults, bound to be ineffective. It is fitting to utilize an approval token.

• The username and passwords ought not to be put away on the gadget. It is fitting to finish the underlying approval and utilize a brief approval token.

To robotize the verification cycle of the application, the application proprietors require client certifications. In such cases utilize an accreditation object that contains client sign-in data.

6. Make an effort not to utilize External capacity

Records that are put away in outside capacity gadgets are coherent by all applications. They can be effortlessly changed at whatever point the client associates the USB stockpiling gadget to the PC.

If the application is erased, the documents are still there in the outside stockpiling. It could bring about a deficiency of secrecy of important information. It is, thusly, encouraged to store records in either interior memory or utilize the SQLite data set.

7. Use Database Encryption

To upgrade information security, it is prudent to get data set records. Those utilizing SQLite can convey an augmentation – SQLCipher, which is a bunch of open-source libraries. It is smaller in size with low upward and gives 256-AES encryption of SQLite information base records straightforwardly. It has become very famous among iOS engineers to get data set documents and it is accessible for Android designers also.

One-stop solution to prevent reverse engineering from Appsealing:

AppSealing security solutions provide end-to-end protection for mobile applications by effectively addressing various security vulnerabilities, including reverse engineering. With AppSealing, developers around the world protect their mobile applications by encrypting DEX, SO, and DLL files, making application code “unreadable” in the event of an attack.

AppSealing Runtime Self-Defense (RASP) protects runtime applications with binary protection, debugging, and anti-decompile. Hash validation of all application components and modules ensures a stable environment and integrity protection.

AppSealing detects rooted devices and Android emulators that have access to the app and block their launch to “clean” their use. This no-code approach has minimal impact on memory, CPU, or battery performance. Just upload the APK and within 10 minutes the full layer of protection will be applied to your app.

Bottom Line:

Reverse engineering is the process of extracting the source code and other resources involved in creating an APK binary. Using commercially available tools, DEX files can be decompiled into JAR files and then into Java source code. Your competitors can use it to display the functionality of the application indefinitely and even secretly copy some functions. Hackers can use this technique to gain access to premium portions of your application by bypassing the authentication process. They can be used in-game cheats to gain an unfair advantage over your competing peers.
