Diogo Sousa _iogosousac — Nora's BEST triology to date. Seriously. Her best!

Jeremy Gimenes jeremy66xcb1d — Ghost in the Wires, Kevin Mitnick's account of his life as a hacker, is engaging enough. After all, Mitnick was operating for many years at the ever-evolving frontier of telephone and computer security. The writing style is lackluster, but this is an enjoyable read for anyone with a casual interest in cybersecurity. Common cultural images of hackers focus on their intelligence. Mitnick does tout his uncanny ability to remember numbers, but he's also the first to point out that his hacking successes are due largely to his penchant for social engineering (which he describes as "the casual or calculated manipulation of people to influence them to do things they would not ordinarily do"). Mitnick's feats are a strong warning against social engineering, often overlooked in discussions of cybersecurity. He describes times he "tailgated" others, confidently following them into a building and thereby bypassing any security cards or personal recognition that were needed for physical access. Other times, he provides examples of how bits of humor or appeals to sympathy can get the person on the other end of the line to trust him immediately. Perhaps more than anything else, Mitnick tells about how a little bit of prior research, into a supervisor's name or a few key phrases about a project, can lead to someone granting him access to essentially whatever sensitive data he desires. The technical aspects of Mitnick's hacking, on the other hand, would probably not fascinate most readers. In short, the specific methods he used, along with the vulnerabilities he attacked, are outdated. (His arrest occurred in 1995, so many of his hacking exploits are now some 20 years in the past.) Modern hackers, or those who follow them, probably care little about the old telephone networks that Mitnick focuses on in the story. On the other hand, he occasionally mentions more modern concepts, like IP spoofing and PGP, and his use of software backdoors is a timeless strategy for computer hacking. As for motive, Ghost in the Wires clearly seeks to portray Kevin Mitnick as a curious hacker, not the dangerous criminal depicted by the FBI and some media during the two and a half year chase that culminated in his arrest. Particularly, Mitnick uses the book to contest numerous "myths" that found their way into court proceedings against him. The book is co-written with Bill Simon, so it's hard to know to who is more responsible for the simplistic, maudlin writing style in Ghost in the Wires. Phrasing like "But have you ever felt that something was so good it couldn't possibly last?" and "I liked a lot of things about my new life," is the norm. Similarly, Mitnick declares at multiple points his regret for all the stress and suffering he caused his mother and grandmother, whom he loves very much. There's a reason that most authors limit such sentiments to the Acknowledgements section. Finally, some of the story's pace is off. The accounts of Mitnick's time on the run become repetitive and slow to a trudge. Fortunately, the chapters about his arrest, trials, jailtime, and release are much more succinct. Overall, Ghost in the Wires is a mostly interesting insight into one hacker's notorious feats, weakened slightly by the age of those feats but bolstered by Mitnick's accounts of social engineering. Combined with concerns about the style and pace, those attributes make this a 3-star book.

Guilherme Andrade gand — I know I read this book halfway during highschool to do a book report about it, but I really don't remember if I liked it or not!
