COCASER: A Code Obfuscation Method in Cyber Attacks for Enhancing Stealth and Evasion of Reverse Shell Payloads

Code obfuscation techniques play a significant role in cyberattacks, enabling attackers to evade detection and exploit vulnerabilities. Bypassing antivirus software is a crucial step in these attacks, and obfuscation techniques can render payloads completely undetectable. This article focuses on how code obfuscation, as a method for disguising the true purpose of code, can effectively obscure reverse shell payloads, granting attackers unauthorized access to targeted systems by bypassing security defenses. This can help cybersecurity solution designers to be aware of a serious problem in the current solutions and comprehend the complexities of code obfuscation and its role in reverse shell payloads for future designs, ultimately ensuring a safer environment for all users. After analyzing common obfuscation techniques and real-world case scenarios, this research proposes a new method for bypassing antivirus software. The results demonstrate that our proposed method evades all wellknown antivirus solutions in the world without exception.
