Each chapter introduces a vulnerability type accompanied by a series of actual reported bug bounties. The book's collection of tales from the field will teach you how attackers trick users into giving away their sensitive information and how sites may reveal their vulnerabilities to savvy users. You'll even learn how you could turn your challenging new hobby into a successful career. You'll learn: How the internet works and basic web hacking concepts How attackers compromise websites How to identify functionality commonly associated with vulnerabilities How to find bug bounty programs and submit effective vulnerability reports Real-World Bug Hunting is a fascinating soup-to-nuts primer on web security vulnerabilities, filled with stories from the trenches and practical wisdom. With your new understanding of site security and weaknesses, you can help make the web a safer place--and profit while you're at it.

Seemingly simple bugs can have drastic consequences, allowing attackers to compromise systems, escalate local privileges, and otherwise wreak havoc on a system. A Bug Hunter's Diary follows security expert Tobias Klein as he tracks down and exploits bugs in some of the world's most popular software, like Apple's iOS, the VLC media player, web browsers, and even the Mac OS X kernel. 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 brokers A 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.

Managing Diversity is the most complete and comprehensive textbook for gaining knowledge of people from every major ethnic and lifestyle group in the U.S. workplace. It is the only one that covers all this as well as the basic diversity concepts, such as culture, cultural differences, stereotyping, prejudice, and discrimination, and managing the diversity function within an organization. The basic philosophy encompasses "unity in diversity," "inclusiveness and valuing diversity," "what's it like to be you?" and "evaluate substance over style." Students get a package that includes textbook, Business Students Guide, and Library Learning Link. Faculty also get a comprehensive Instructors Manual and PowerPoint slides. From the Preface : How This Book Can Change Your Life This book can do more for you than just provide information about changes in the multicultural workplace. It provides tools for you to change your life-if you to choose to raise your awareness, change limiting beliefs, and adopt new success strategies. Transformation, or lasting change, can only take place at the level of belief, so this book is designed to help you open up your worldview-and therefore transform it. Such transformation will open up richer relationships with people who hold quite different worldviews. Is This Book For You? This book is for you if you see yourself as a workplace leader-now or in the future-whether you take a leadership role as the new member of a work team, the head of an organization, or somewhere in between. This book is for you if you're ready to develop the people power and people skills you need for managing diversity. In this book you'll get the information you need to make informed choices-as well as the processes for broadening your viewpoints and integrating new success skills into your daily interactions.

Build a better defense against motivated, organized, professional attacks Advanced Penetration Testing: Hacking the World's Most Secure Networks takes hacking far beyond Kali linux and Metasploit to provide a more complex attack simulation. Featuring techniques not taught in any certification prep or covered by common defensive scanners, this book integrates social engineering, programming, and vulnerability exploits into a multidisciplinary approach for targeting and compromising high security environments. From discovering and creating attack vectors, and moving unseen through a target enterprise, to establishing command and exfiltrating data—even from organizations without a direct Internet connection—this guide contains the crucial techniques that provide a more accurate picture of your system's defense. Custom coding examples use VBA, Windows Scripting Host, C, Java, JavaScript, Flash, and more, with coverage of standard library applications and the use of scanning tools to bypass common defensive measures. Typical penetration testing consists of low-level hackers attacking a system with a list of known vulnerabilities, and defenders preventing those hacks using an equally well-known list of defensive scans. The professional hackers and nation states on the forefront of today's threats operate at a much more complex level—and this book shows you how to defend your high security network. Use targeted social engineering pretexts to create the initial compromise Leave a command and control structure in place for long-term access Escalate privilege and breach networks, operating systems, and trust structures Infiltrate further using harvested credentials while expanding control Today's threats are organized, professionally-run, and very much for-profit. Financial institutions, health care organizations, law enforcement, government agencies, and other high-value targets need to harden their IT infrastructure and human capital against targeted advanced attacks from motivated professionals. Advanced Penetration Testing goes beyond Kali linux and Metasploit and to provide you advanced pen testing for high security networks.

On my thirteenth birthday, my life changed for ever. That's when I learned the shocking truth: I'm a half-vampire. Think that sounds cool? Think again! I've been attacked by an evil vampire bat, had huge cravings for my best friend's blood, and nearly died from eating a pizza (half-vampires aren't great with garlic). Writing my secret blog is the only thing that's kept me from going completely crazy. As if life couldn't get any more complicated, there have been some vicious attacks in the local woods. Vampire-mad Tallulah (definitely not my girlfriend) thinks a super-vampire is behind them - and she's desperate to prove it, with a mysterious chain that's supposed to glow red-hot when a vampire is close by. And I have a horrible feeling that the chain's going to turn red-hot any day now . . . A new novel from award-winning author Pete Johnson that taps into the very current interest in vampires - done with Pete's humorous, accessible touch.

“Halting State [is] a near-future story that is at once over-the-top and compellingly believable.” – Vernor Vinge, author of Rainbows End In the year 2018, Sergeant Sue Smith of the Edinburgh constabulary is called in on a special case. A daring bank robbery has taken place at Hayek Associates—a dot-com start-up company that’s just floated onto the London stock exchange. But this crime may be a bit beyond Smith’s expertise. The prime suspects are a band of marauding orcs with a dragon in tow for fire support. The bank is located within the virtual reality land of Avalon Four, and the robbery was supposed to be impossible. When word gets out, Hayek Associates and all its virtual “economies” are going to crash hard. For Smith, the investigation seems pointless. But the deeper she digs, the bigger the case gets. There are powerful players—both real and pixelated—who are watching her every move. Because there is far more at stake than just some game-head’s fantasy financial security…
