In this one-of-a-kind account, you'll see how the developers responsible for these flaws patched the bugs—or failed to respond at all. As you follow Klein on his journey, you'll gain deep technical knowledge and insight into how hackers approach difficult problems and experience the true joys (and frustrations) of bug hunting.Along the way you'll learn how to:Use field-tested techniques to find bugs, like identifying and tracing user input data and reverse engineering Exploit vulnerabilities like NULL pointer dereferences, buffer overflows, and type conversion flaws Develop proof of concept code that verifies the security flaw Report bugs to vendors or third party brokersA Bug Hunter's Diary is packed with real-world examples of vulnerable code and the custom programs used to find and test bugs. Whether you're hunting bugs for fun, for profit, or to make the world a safer place, you'll learn valuable new skills by looking over the shoulder of a professional bug hunter in action.

    Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes became ever more brazen, eventually leading to the first-ever blackouts triggered by hackers. They culminated in the summer of 2017 when malware known as NotPetya was unleashed, compromising, disrupting, and paralyzing some of the world's largest companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. NotPetya spread around the world, inflicting an unprecedented ten billions of dollars in damage--the largest, most penetrating cyberattack the world had ever seen.The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in the internet's history: Sandworm. Believed to be working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled, state-sponsored hacking force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike.From WIRED senior writer Andy Greenberg comes Sandworm, the true story of the desperate hunt to identify and track those attackers. It considers the danger this force poses to our national stability and security. And as the Kremlin's role in manipulating foreign governments and sparking chaos globally comes into greater focus, Sandworm reveals the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield--where the line between digital and physical conflict begins to blur, with world-shaking implications.

    Apache: The Definitive Guide, written and reviewed by key members of the Apache Group, is the only complete guide on the market today that describes how to obtain, set up, and secure the Apache software.Apache was originally based on code and ideas found in the most popular HTTP server of the time: NCSA httpd 1.3 (early 1995). It has since evolved into a far superior system that can rival (and probably surpass) almost any other Unix-based HTTP server in terms of functionality, efficiency, and speed. The new version now includes support for Win32 systems. This new second edition of Apache: The Definitive Guide fully describes Windows support and all the other Apache 1.3 features. Contents include:The history of the Apache Group Obtaining and compiling the server Configuring and running Apache on Unix and Windows, including such topics as directory structures, virtual hosts, and CGI programming The Apache 1.3 Module API Apache security A complete list of configuration directives With Apache: The Definitive Guide, web administrators new to Apache can get up to speed more quickly than ever before by working through the tutorial demo. Experienced administrators and CGI programmers, and web administrators moving from Unix to Windows, will find the reference sections indispensable.

    They are now standard features in a wide range of languages and popular tools, including Perl, Python, Ruby, Java, VB.NET and C# (and any language using the .NET Framework), PHP, and MySQL.If you don't use regular expressions yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regularexpressions, this book is a stunning eye-opener.As this book shows, a command of regular expressions is an invaluable skill. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Regular expressions can save you time and aggravation. They can be used to craft elegant solutions to a wide range of problems. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them.Yet despite their wide availability, flexibility, and unparalleled power, regular expressions are frequently underutilized. Yet what is power in the hands of an expert can be fraught with peril for the unwary. Mastering Regular Expressions will help you navigate the minefield to becoming an expert and help you optimize your use of regular expressions.Mastering Regular Expressions, Third Edition, now includes a full chapter devoted to PHP and its powerful and expressive suite of regular expression functions, in addition to enhanced PHP coverage in the central "core" chapters.
