If your system gets hacked, chances are it will be from a Trojan. A Microsoft Security Intelligence report tabulated a 300 percent increase in the number of Trojan downloaders and droppers the last half of 2007 -- a trend which security experts say will continue to exponentially grow. Consistent with malware trends, the biggest security threats are moving to the Web and consequently experts say that they expect to see the number of Trojans rise exponentially. The reason? Trojans are by far the most "financially interesting" malware, experts say.
"It"s the path of least resistance," said Doug Camplejohn, CEO and cofounder of security company Mi5. "For most enterprises, it"s where they"re least protected." These Trojans allow attackers to install a small downloader onto unsuspecting users machines, usually without their consent, in order to record passwords, credit card, bank account numbers and other personal identifying information.
