The number of threats has grown to a worrying level since last year, the numbers showing a growth of over 26% in the same period as last year – statistics shown by the anti-malware labs of Panda Security. Specialist identified in the first trimester of 2011, a average of 73.000 malware roots, most of which ware found to trojans.
Trojans still remain the most popular form internet threats, consisting in almost 70% of the entire malware. This phenomenon is not surprising, knowing their profitability and easy use by hackers trying to steal money from the users of internet banking.
The main cause of this spread of Trojans is the ease of finding a program for creating one. In just a few moments, a person with no technical background can create one of these cyber-spies.
But not all forms of trojans have signaled a growth, for example: the number of banking trojans has gone down, the number of hackers has remained constant, the number of “false viruses”(rogueware) has also seen a demise but the auto-downloader programs has seen a significant growth.
The auto-downloader programs are a type of trojans who, after infecting a computer, connect to the internet and download additional malware. Hackers use this method because of the small space it occupies on the hard-drive(the actual program containing only a few lines of code), therefore minimizing the possibility of it being discovered.
