The number of attacks involving targeted Trojans are increasing, with up to 70 targeted Trojans a day recorded in the month of April this year. This represents an increase of 250% over the December 2007 level of just 28 per day.

A targeted Trojan is sent only to a select group — or even a specific user — per attack. Almost certainly personalized, it leverages on sophisticated social engineering to persuade a recipient to open an e-mail and its associated attachment. Because the identify of a targeted individual in such an attack is presumably known, or could at least be guessed at, targeted Trojans can result in more damage in the event of a successful attack.

Do you suppose that better user-education will be sufficient to blunt the success rate of targeted Trojans? Or is depending on users to behave sensibly already a lost cause?
