| | [AI summary] The text provides an in-depth exploration of various x86-64 instruction set architectures, focusing on arithmetic operations (ADD, SUB, MUL, SMUL, DIV, SDIV), logical operations (AND, OR, XOR, NOT), and control flow instructions. It details the implementation of these instructions in the QBX virtual machine, emphasizing how they emulate real x86-64 instructions while managing the flags register and handling different operand sizes (8-bit and 16-bit). The text also discusses the nuances of flag handling, register operations, and macro-based code generation to streamline instruction implementation.

| [AI summary] The CTF writeup details the process of solving a cryptographic challenge involving AES key recovery through side-channel attacks. The key was recovered by analyzing timing leaks from the AES decryption process, specifically the doSboxInv function's execution time. The recovered round 10 key was then used to invert the AES key schedule to obtain the original encryption key, which was the flag. The writeup also discusses the challenges of directly recovering the original key due to timing noise and the importance of using statistical correlation to identify the correct key.
