This comprehensive playbook provides expert techniques for classical cipher identification and breaking. It covers fundamental methods like frequency analysis, Kasiski examination, and Index of Coincidence (IC), enabling the decryption of monoalphabetic, polyalphabetic, and transposition ciphers (Vigenere, Caesar, Playfair, etc.). It also guides the decoding of various formats (Base64, Hex, Morse).

This expert playbook provides a comprehensive guide to lattice-based cryptanalysis techniques. It covers fundamental concepts like SVP and CVP, and deep dives into advanced algorithms such as LLL and BKZ reduction. Key attack applications include Coppersmith's method for finding small roots in RSA, solving the Hidden Number Problem for recovering DSA/ECDSA nonces, and analyzing knapsack ciphers. Essential for CTF and academic cryptanalysis.

This playbook provides expert-level techniques for cryptanalysis of symmetric encryption. It details how to exploit weaknesses in various modes and algorithms, including CBC padding oracle attacks, ECB mode exploitation, bit flipping attacks, stream cipher key reuse, and meet-in-the-middle attacks. Essential for authorized penetration testing and CTF challenges.

This comprehensive guide details the methodology for reverse engineering macOS and Mach-O binaries. It covers analyzing application bundles, deciphering Objective-C/Swift symbols, examining code signing and hardened runtime features, and performing both static (using tools like Ghidra, IDA) and dynamic analysis (using lldb, Frida) to aid in malware analysis and platform security research.
