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.

Strengthen your coding skills by exploring the weird world of esoteric programming languages.Explore the wonderful, wild, and often weird world of esoteric programming languages. The book begins with the history and theory of programming languages, addressing concepts like Turing machines and Turing completeness. You're then treated to a tour of three "atypical" programming languages, real languages that are unusual and require out of the box thinking. Following that are five chapters on existing esoteric languages (esolangs), some of which are easy to use, others quite difficult, and others novel because of their approach (programming with pictures, for example). Finally, the remaining chapters detail the development and use of two entirely new programming languages. The main point of the book is to encourage readers to think differently about what it means to express thought using a programming language, and to explore the limits and boundaries of what a programming language might be. Though readers aren't likely to use any of these languages in their day jobs, learning to think in these languages will make them better, more confident programmers.

The fascinating inside story of how the Android operating system came to be.In 2004, Android was two people who wanted to build camera software but couldn't get investors interested. Today, Android is a large team at Google, delivering an operating system (including camera software) to over 3 billion devices worldwide. This is the inside story, told by the people who made it happen.Androids: The Team that Built the Android Operating System is a first-hand chronological account of how the startup began, how the team came together, and how they all built an operating system from the kernel level to its applications and everything in between. It describes the tenuous beginnings of this ambitious project as a tiny startup, then as a small acquisition by Google that took on an industry with strong, entrenched competition. Author Chet Haase joined the Android team at Google in May 2010 and later recorded conversations with team members to preserve the early days of Android's history leading to the launch of 1.0. This engaging and accessible book captures the developers' stories in their own voices to answer the question: How did Android succeed?
