Code Obfuscation Techniques – New Technologies to Handle Cyber Attack

Awareness of online work is at its paramount. The sector that had not begin using the online services is also now a major part of the online business, including E-commerce, Web-services and even banking. This major change has come recently owing to Covid-19 situation.  With the increase in the usage of the online platform, the need to use it more securely also arises.

Who all need to obfuscate the code?

Code Obfuscation Techniques are some of these techniques that are used to prevent the company’s website from being cyber attacked. The Code obfuscation is used primarily by the people who own the websites and platforms to sell, trade or any kind of business what so ever.

The Cyber attackers have often used the reverse engineering in order to attack and hack web sites, and even servers. But Code Obfuscation Techniques, prevent any kind of reverse engineering too. It is important that this technique must be used so as to prevent any issues to the users, and of-course, you as a business owner.

Moreover, this technique can be avoided by those using web services or code using secured servers. However, for those deploying code at the client side, obfuscation techniques come in handy to prevent any unforeseen claim or breach of credit.

Methodology of  Source Code Obfuscation

  1. Data Transformation:

    Data transformation can be done by using binary or any other data instead of the actual form in which the data is processed. This restrcits the hackers to decode.

  2. Code Flow Obfuscation:

    Code flow obfuscation can be done when we change the orientation of the code. This prevents the decoding as the hackers often get confused about the application of the code and the path it follows. So if the coder alters the statement of the program keep the result same, the chances of being hacked are alleviated.

  3. Address Obfuscation:

    Making the code appear complex can be done by obfuscating the address. This enhances the unpredictability and reduces the attacks. Moreover, reverse engineering cannot be used in this case as the program cannot be replicated even if the application is understood.

  4. Renew the Obfuscated code:

    Each time using a new way of obfuscating the code generally frustrates the hackers. Eventually, deviating them from hacking.

  5. Process of Obfuscation:

    Two processes are involved in this. First one entails obfuscating plain text message so that the messages are not easily read. Secondly, the Objective-C metadata is encrypted. This obscures any sensitive information. So now when the code needs to be run, the information is decrypted.

  6. Assembly code instructions Obfuscation:

    ‘Jump-in-the-Middle’ is a commonly used way to obfuscate the assembly code. This means that the code is hidden within another code. Each time a hacker will try to hack, the output given would be incorrect and confusing, i.e. not in sync with the decoded way.

  7. To Obfuscate debugged information:

    When debugging is tried, it helps the hacker to discover its source code. In such a case the recompiling and decompiling of the program is possible. It is for this reason that the pop-up appears asking for access to an unauthorized access. Therefore, obfuscation coding is necessary.

Difference between Encryption and Obfuscation

Obfuscation is a process to hide the actual meaning of the content file. This process makes the content confusing, and complex for anyone to read. This can be read by someone who has the authority to run the program. On the other hand Encryption is a process that transforms the content of the file. This restricts and limits the hackers or outsiders to read unless a special key is used to decrypt the message.
