The hacker with perhaps the most famous first name around, Kevin Mitnick, has gone from computer hacking of the sort that gets one on the FBI's Most Wanted list (and into years of solitary confinement) to respected security consultant and author, helping people minimize the sort of security holes he once exploited for fun. His new book is called Ghost in the Wires: My Adventures as the World's Most Wanted Hacker; it's his first since the expiration of an agreement that he could not profit from books written about his criminal activity. Kevin's agreed to answer your questions; we'll pass the best ones on to him, and print his answers when they're ready. Note: Kevin also answered Slashdot questions most of a decade ago; that's a good place to start. Please observe the Slashdot interview guidelines: ask as many questions as you want, but please keep them to one per comment.
