Kingpin


Book Description

Former hacker Kevin Poulsen has, over the past decade, built a reputation as one of the top investigative reporters on the cybercrime beat. In Kingpin, he pours his unmatched access and expertise into book form for the first time, delivering a gripping cat-and-mouse narrative—and an unprecedented view into the twenty-first century’s signature form of organized crime. The word spread through the hacking underground like some unstoppable new virus: Someone—some brilliant, audacious crook—had just staged a hostile takeover of an online criminal network that siphoned billions of dollars from the US economy. The FBI rushed to launch an ambitious undercover operation aimed at tracking down this new kingpin; other agencies around the world deployed dozens of moles and double agents. Together, the cybercops lured numerous unsuspecting hackers into their clutches. . . . Yet at every turn, their main quarry displayed an uncanny ability to sniff out their snitches and see through their plots. The culprit they sought was the most unlikely of criminals: a brilliant programmer with a hippie ethic and a supervillain’s double identity. As prominent “white-hat” hacker Max “Vision” Butler, he was a celebrity throughout the programming world, even serving as a consultant to the FBI. But as the black-hat “Iceman,” he found in the world of data theft an irresistible opportunity to test his outsized abilities. He infiltrated thousands of computers around the country, sucking down millions of credit card numbers at will. He effortlessly hacked his fellow hackers, stealing their ill-gotten gains from under their noses. Together with a smooth-talking con artist, he ran a massive real-world crime ring. And for years, he did it all with seeming impunity, even as countless rivals ran afoul of police. Yet as he watched the fraudsters around him squabble, their ranks riddled with infiltrators, their methods inefficient, he began to see in their dysfunction the ultimate challenge: He would stage his coup and fix what was broken, run things as they should be run—even if it meant painting a bull’s-eye on his forehead. Through the story of this criminal’s remarkable rise, and of law enforcement’s quest to track him down, Kingpin lays bare the workings of a silent crime wave still affecting millions of Americans. In these pages, we are ushered into vast online-fraud supermarkets stocked with credit card numbers, counterfeit checks, hacked bank accounts, dead drops, and fake passports. We learn the workings of the numerous hacks—browser exploits, phishing attacks, Trojan horses, and much more—these fraudsters use to ply their trade, and trace the complex routes by which they turn stolen data into millions of dollars. And thanks to Poulsen’s remarkable access to both cops and criminals, we step inside the quiet, desperate arms race that law enforcement continues to fight with these scammers today. Ultimately, Kingpin is a journey into an underworld of startling scope and power, one in which ordinary American teenagers work hand in hand with murderous Russian mobsters and where a simple Wi-Fi connection can unleash a torrent of gold worth millions.

Start with Why


Book Description

The inspirational bestseller that ignited a movement and asked us to find our WHY Discover the book that is captivating millions on TikTok and that served as the basis for one of the most popular TED Talks of all time—with more than 56 million views and counting. Over a decade ago, Simon Sinek started a movement that inspired millions to demand purpose at work, to ask what was the WHY of their organization. Since then, millions have been touched by the power of his ideas, and these ideas remain as relevant and timely as ever. START WITH WHY asks (and answers) the questions: why are some people and organizations more innovative, more influential, and more profitable than others? Why do some command greater loyalty from customers and employees alike? Even among the successful, why are so few able to repeat their success over and over? People like Martin Luther King Jr., Steve Jobs, and the Wright Brothers had little in common, but they all started with WHY. They realized that people won't truly buy into a product, service, movement, or idea until they understand the WHY behind it. START WITH WHY shows that the leaders who have had the greatest influence in the world all think, act and communicate the same way—and it's the opposite of what everyone else does. Sinek calls this powerful idea The Golden Circle, and it provides a framework upon which organizations can be built, movements can be led, and people can be inspired. And it all starts with WHY.




Strengthening Forensic Science in the United States


Book Description

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
