In May 1998, the US Congress invited the seven members of the L0pht to testify on the state of government computer security. Two years later, that same group rode the Dot-com bubble to create the preeminent security consultancy the industry has ever known, @stake. Along the way, they stood up against tech giants like Microsoft, Oracle, Novell and others to expose weaknesses in those companies' premiere products. Despite the L0pht's technical prowess, the group could not keep what they had built together as money and internal politics turned friend against friend. Look inside L0pht Heavy Industries, or simply The L0pht, one of the most influential hacker groups in history. From formation, to congressional testimony, to going legit and the aftermath that followed. Follow the hacker 'Space Rogue' as he takes you on a journey through the magical hacker scene of the 1990s.The L0pht hacker collective no longer exists, but its legacy lives on. L0pht set the standard for how the cyber security industry now releases vulnerability information. Famous hackers that were once L0pht members, Mudge, Weld Pond, Kingpin, Dildog, Space Rogue, and others have done even more impressive things in the following years. The hackers and consultants hired by @stake and indoctrinated into the L0pht way of thinking have now become giants in the industry. All the hackers who read security information off the L0pht's website, downloaded software from the Whacked Mac Archives, or watched the Hacker News Network and became inspired have changed the world more than the L0pht could have ever done alone. The L0pht's message of bringing security issues to light and getting them fixed still echoes throughout the industry and is more important today than ever. The L0pht's dire warning of an increasingly dependent culture on a fragile Internet made during their testimony twenty-five years ago still holds true. In fact, the Internet may be in even worse shape today. Is it too late to listen?
