This is session 2 of our binary hacking lab series, in which we will practice binary patching skills to insert backdoor into Windows PE / Linux ELF binaries. Through this exercice, you will get yourself familiarized with Windows PE / Linux ELF structure and learn how to parse the file manually as well as writing shellcode in assembly and edit native opcode.

💻Prerequisites: Bring your own laptop with x64 Intel/AMD Windows and Linux OS/VM or any comparable cloud compute instance.
