The goal is to distract the reader with the complicated syntax of what they are reading and make it difficult for them to determine the true content of the message. Obfuscation in computer code uses complex roundabout phrases and redundant logic to make the code difficult for the reader to understand. Obfuscation aims to make reverse engineering difficult and not worth the trouble. Compiler optimization and program synthesis are two other deobfuscation techniques. These techniques include program slicing, which involves narrowing the program code to just the relevant statements at a particular point in the program. The 2020 SolarWinds attack is an example of hackers using obfuscation to evade defenses.ĭeobfuscation techniques can be used to reverse engineer - or undo - obfuscation.
Unfortunately, malicious code writers also use these methods to prevent their attack mechanisms from being detected by antimalware tools.
A tool called an obfuscator will automatically convert straightforward source code into a program that works the same way, but is more difficult to read and understand. Other approaches include stripping out potentially revealing metadata, replacing class and variable names with meaningless labels and adding unused or meaningless code to an application script.

Programming code is often obfuscated to protect intellectual property or trade secrets, and to prevent an attacker from reverse engineering a proprietary software program.Įncrypting some or all of a program's code is one obfuscation method. Obfuscation means to make something difficult to understand.
