Reverse engineering and protecting your app from reverse engineering

Published on


We are using devices such as smartphones, computers or PCs, mobiles, etc. to perform tasks such as sending pictures or text messages, calling someone, searching for information, downloading software, recording information or storing large amounts of data, etc. If you are a businessman, you frequently use the internet to perform any integral task. Also, you are frequently sharing information with the parties. So, you are probably using passcodes or usernames to operate any program. Anybody can easily extract your password, username, etc. They can access something that is integral to the business. Many business organisations have undergone huge financial losses due to data privacy issues. The hackers are able to perform the function of  reverse engineering to extract some important information from the business.

How are hackers able to steal information?

The hackers are able to perform some functions such as decompiling, dissembling, analysing data or systems, etc., and stealing information. It is a method of dismantling an object to learn how it works. The main aim of this function is to analyse and acquire knowledge about the workings of the system. It is also used to duplicate an object. The experts or authorised hackers also know how to protect app from reverse engineering to learn the overall functioning of a system. They thoroughly research the hacker’s methods of obtaining information.They try to understand the behaviour of the hackers. The study also examines the pattern of information flow in the system. The hackers can use the passcodes or passwords to unlock the applications or software.

But if unauthorised hackers are able to perform the process easily, then they can steal significant information, misuse the data, or cause privacy invasion. You can protect the business’s sensitive data. It is a process of studying the function of a finished product using special tools or methods. This process is performed by authorised hackers to deeply study the operations of the system or software. They can detect vulnerabilities in the system and the methods of extracting information.

Depending upon the weaknesses of the system or operation, they can recommend some best strategies to prevent data invasion. They can understand the behaviour of malicious attackers or hackers on the system. The researchers can also detect malware or viruses invading the system. They can restore the complex algorithm to prevent data invasion. They can also complicate the data of the executable files or folders, applications, etc. So, the hackers cannot interpret data or information from the system. This technique is potentially useful for security software developers who are working on different types of formats or protocols.

How to protect an app against reverse engineering?

You should protect your Android app from the reverse process. Applications such as Android can be decompiled easily. The experts should convert the DEX data to JAR files. The following are the methods of protecting the system against reverse processing.

Assistance for Proguard

To secure mobile apps, the open source tool, also known as the Java Cross Platform, is used.The experts use an application that accesses the code and performs functions such as shrinking, obfuscating, etc. The shrink method is used to eliminate unwanted characteristics, classes, or fields from the devices. The process of optimization is performed to enhance the bytecode of the application in several ways. They also perform the operation of obscuscation of any fields, classes, or ways and reassign some vague names that cannot be identified easily. They shrink the codebase to improve efficiency, and the process even becomes complicated. The process of pre-verification of information is applied to Java 6 or JME.

The experts recommend executing the compile time to a gridle file and performing functions such as obfuscation, compression, and optimization. The experts also use systems such as Pro Guard to fix certain problems. It is used to copy the manifests from the resource files without any modifications. In the output jars, you should not use the directory entries. If you are using a software that uses the components, then these names can be added manually. You should manually enter the settings of API as the Pro Guard is not programmed for such settings. The configuration of the system of syntax should be descriptive, clear, and precise. The methods for protecting an app from reverse engineering are as follows.

Tamper detection

It is a process of accessing if the identity used to log into the account is tampered with. To access your software, you should use the Play Store option. You can verify the installation source or your programme can be disabled as well. You can also use a debugger that is hooked up, and you can use the code. Then, your app can be modified, and you can access the signature of your app.

Transferring the data to the servers.

The code should be transferred from the apps to the encrypted language web service. The company should use a program that consists of an algorithm or code that is unique so it cannot be stolen easily. The data should be allowed to be processed on a server far away. The information is then accessed from the applications.

Encrypting the data

The encrypted data should be stored in the database only. This data should be encrypted in the database, so you need not worry about encrypting and decrypting the data.

SSL should be used with caution by users.

SSL is used in the applications to ensure the safety of the code. You can use several methods to utilise the SSLSocket factory interface. Such applications are vulnerable to the attacks caused by third parties. In this way, data is transferred to the TSL protocol.

Using the secure credentials

The credentials of the users should be kept safe. Users should not use their credentials too many times in an app. In this way, they can reduce problems such as phishing assaults, and hence they can use the authorization token. They should use passwords and usernames that should not be kept on the device. The users should use the initial authorization and should use the authorization token. They can still use advanced methods such as using the hashing algorithm, hiding the API keys, avoiding external storage and using the method of database encryption.
