What is the current trend?
Just as at the end of the 90s and from 2003 to 2004 we saw an explosion in the Internet worm phenomenon with massive epidemics (ILoveYou, Sircam, SQLSlammer…), in 2005 this trend began to decline. As time passed, two things became apparent: massive epidemics were less frequent and had less impact and malware was becoming increasingly sophisticated technologically. In addition, the objectives of these attacks shifted from being massive to being targeted. In fact, in 2005 there were no serious alerts caused by threats; all alerts were of moderate intensity. Moreover, new types of threats are appearing which are not necessarily viruses, and whose main strength is the ability to go undetected by users and security solutions and offer their creators the possibility of taking remote-control over computers and entering them without anybody realizing. This scenario could be described as a ‘silent epidemic’ as opposed to the “massive epidemics” predominant in the industry until 2004. etc.
