Name mangler code4/19/2023 This technique involves naming variables confusingly so that the original intent of using them is intelligently masked. Essentially, the security team, in consultation with the development team, decides which type of obfuscation to employ on the code. Obfuscation techniques also vary according to the operation they perform on the code. Obfuscation acts at multiple levels – it is applied either at the level of semantic structure/lexical code structure or at the level of data structure/control flow. The time, cost, and resource factor tilt the scale in favor of abandoning the code when it is obfuscated since the decompiled code is rendered unintelligible. This process restricts the malicious access to source code, and depending upon the type of obfuscation technique implemented, it ensures varied levels of code protection. By making an application hard to reverse engineer, developers ensure that their product’s intellectual property is guarded against security threats, unauthorized access, and discovery of application vulnerabilities. It is just a precautionary way to render the code unusable for a potential hacker, who may lay their hands over the executable code of an application.Ĭode obfuscation is particularly useful for open-source applications, which pose a huge disadvantage in terms of hackability of code for personal gains. Code obfuscation does not impact the application’s interface meant for the end user or the intended output of the code. The source code itself is obfuscated, so that it becomes unintelligible and impossible for a third-party to understand it, leave alone execute it. Code ObfuscationĬode obfuscation is the modification of executable code so that it is not available for comprehension, interpretation, and execution. More often than not, this technique acts as a primary defense mechanism against hacking attempts and guards against common attacks, like code injection, reverse engineering, and tampering with personal information of customers and application users. It is one of the most recommended AppSec initiatives by security professionals around the world and often takes care of the bare minimum security needs of your application. Code obfuscation figures among one of the most preferred application security techniques to guard against application hacking.
