Next, you’ll learn to perform common attacks, like those targeting an API’s authentication mechanisms and the injection vulnerabilities commonly found in web applications. You’ll also learn techniques for bypassing protections against these attacks. In the book’s nine guided labs, which target intentionally vulnerable APIs, you’ll practice:Enumerating APIs users and endpoints using fuzzing techniquesUsing Postman to discover an excessive data exposure vulnerabilityPerforming a JSON Web Token attack against an API authentication processCombining multiple API attack techniques to perform a NoSQL injectionAttacking a GraphQL API to uncover a broken object level authorization vulnerability By the end of the book, you’ll be prepared to uncover those high-payout API bugs other hackers aren’t finding and improve the security of applications on the web.

An accessible yet rigorous crash course on recursive programming using Python and JavaScript examples.Recursion has an intimidating reputation: it's considered to be an advanced computer science topic frequently brought up in coding interviews. But there's nothing magical about recursion. The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it's often poorly taught and clarifying the fundamental principles of all recursive algorithms. You'll learn when to use recursive functions (and, most importantly, when not to use them), how to implement the classic recursive algorithms often brought up in job interviews, and how recursive techniques can help solve countless problems involving tree traversal, combinatorics, and other tricky topics. This project-based guide contains complete, runnable programs to help you learn: How recursive functions make use of the call stack, a critical data structure almost never discussed in lessons on recursionHow the head-tail and "leap of faith" techniques can simplify writing recursive functionsHow to use recursion to write custom search scripts for your filesystem, draw fractal art, create mazes, and moreHow optimization and memoization make recursive algorithms more efficient Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If you've shied away from learning recursion but want to add this technique to your programming toolkit, or if you're racing to prepare for your next job interview, this book is for you.

A hands-on guide to hacking computer systems from the ground up, from capturing traffic to crafting sneaky, successful trojans.A crash course in modern hacking techniques, Ethical Hacking is already being used to prepare the next generation of offensive security experts. In its many hands-on labs, you’ll explore crucial skills for any aspiring penetration tester, security researcher, or malware analyst. You’ll begin with the basics: capturing a victim’s network traffic with an ARP spoofing attack and then viewing it in Wireshark. From there, you’ll deploy reverse shells that let you remotely run commands on a victim’s computer, encrypt files by writing your own ransomware in Python, and fake emails like the ones used in phishing attacks. In advanced chapters, you’ll learn how to fuzz for new vulnerabilities, craft trojans and rootkits, exploit websites with SQL injection, and escalate your privileges to extract credentials, which you’ll use to traverse a private network. You’ll work with a wide range of professional penetration testing tools—and learn to write your own tools in Python—as you practice tasks like: Deploying the Metasploit framework’s reverse shells and embedding them in innocent-seeming filesCapturing passwords in a corporate Windows network using MimikatzScanning (almost) every device on the internet to find potential victimsInstalling Linux rootkits that modify a victim’s operating systemPerforming advanced Cross-Site Scripting (XSS) attacks that execute sophisticated JavaScript payloads Along the way, you’ll gain a foundation in the relevant computing technologies. Discover how advanced fuzzers work behind the scenes, learn how internet traffic gets encrypted, explore the inner mechanisms of nation-state malware like Drovorub, and much more. Developed with feedback from cybersecurity students, Ethical Hacking addresses contemporary issues in the field not often covered in other books and will prepare you for a career in penetration testing. Most importantly, you’ll be able to think like an ethical hacker⁠: someone who can carefully analyze systems and creatively gain access to them.
