Python in Action: Using Python to Become an Elite Hacker

This book is the Chinese translation of Violent Python, written for security practitioners who need to quickly write specialized tools for specific scenarios. It is organized around real-world cases: it starts with setting up a development environment and installing third-party libraries, briefly reviews Python variables, strings, lists, dictionaries, conditional statements, exception handling, functions, iteration, file I/O, and the sys/os modules, and then builds hands-on familiarity through two starter programs (a UNIX password cracker and a Zip file password cracker). It then moves into penetration testing: writing a TCP full-connect port scanner, multithreaded scanning, grabbing application banners, and working with nmap code; using Pexpect to interact with SSH, using Pxssh to brute-force passwords, and building an SSH botnet from weak private keys; building an anonymous FTP scanner, batch password attempts, injecting malicious code into webpages, and collaborating with Metasploit to carry out SMB attacks and proof-of-concept exploits. The forensics and interception part covers electronic forensics, network traffic analysis, and wireless security, introducing topics such as information gathering and antivirus evasion. Every example is presented as a runnable script, emphasizing “achieving the required functionality with very little code,” making it suitable for security engineering practice and classroom cases.
