Explore the intricate world of binary file formats through this comprehensive security training course that demystifies how executables are structured and function. Dive deep into the Portable Executable (PE) format used by Windows systems, examining DOS headers, NT headers, file headers, optional headers, section headers, imports, exports, relocations, and security features like code signing and ASLR. Master the analysis of PE components including bound imports, delay load imports, thread local storage, resources, and debug information while practicing with the innovative Binary Scavenger Hunt tool that generates randomized PE binaries for hands-on learning. Transition to understanding the Executable and Linkable Format (ELF) used in Unix-like systems, comparing and contrasting ELF headers, program headers, section headers, and dynamic linking mechanisms with their PE counterparts. Gain practical experience using tools like readelf and Dependency Walker to analyze binary structures, and explore advanced topics including runtime importing, IAT hooking, PLT operations, packers like UPX, and even basic virus construction concepts. Learn through a structured approach that combines theoretical knowledge with interactive exercises, pop quizzes, and laboratory sessions that reinforce understanding of how compilers generate executables and how these binaries operate at the system level.
