What is Evasion Techniques for Web Backdoors about?

This document discusses web application backdoors and techniques for evading detection. It describes common detection methods like signature-based antivirus and specialized tools that scan code. It then provides three evasion techniques: 1) using variable functions to call base64 decoding instead of the function directly, 2) minimizing backdoor code size to avoid detection, and 3) hiding backdoor code in image EXIF headers and triggering it by HTTP header to remain undetected from scanners, audits, and logs
