Recent computer espionage cases reveal seemingly countless ways to steal data. You can take a few simple steps to fight back. Not so long ago, I saw only one or two computer espionage cases a year. The pace picked up about three or four years ago, when malware began turning professional. Today, computer espionage and malware go hand in hand, so it's not only surprising but amazing to me how many companies fail to grasp the seriousness of today's Trojans and worms. For far too many firms, this realization hits home in the form of serious monetary damages. News accounts are full of cases where cybercriminals were paid by companies to burrow into a competitor's databases to extract crucial information. Do an Internet search on "corporate espionage," and most of the articles you will find talk about external attackers gaining access to internal information. Almost as many talk about trusted insiders sending private information to the competitor just before taking a new job there.
