Panda: Trojans accounted for more than 60 percent of new malware created during the second quarter of 2008
July 2008 by Panda Security
Over 63 percent of new malicious codes that appeared during the second quarter of 2008 were Trojans, according to the latest quarterly report from PandaLabs. Adware, with 22.40%, was the second most frequently created type of malware in the same period.
"In the present scenario, it is unlikely for a Trojan to infect a large number of computers, as this would attract attention and goes against the interests of cyber-criminals. They prefer instead to create numerous different Trojans, targeting users of a specific service or utility, etc., instead of trying to massively propagate a single example", explains Luis Corrons, Technical Director of PandaLabs, who adds: "this is why Trojans consistently figure as the type of malware with most individual examples in circulation."
With respect to the virulence of specific examples, the Bagle.RP worm infected most computers, followed by the Puce.E and Bagle.SP worms.
Trojans were also the type of malware responsible for most infections in the second quarter of 2008, accounting for 28.7% of the total. Adware, which held first place in the first quarter of the year, was the cause of 22.03% of infections, and worms were the culprits in 13.52% of cases.
"Trojans are responsible for most infections, but they do it with thousands of different variants. Worms, however, operate in a different way, with perhaps one example being responsible for tens of thousands of infections. That’s why in terms of individual malicious code, worms are often the most prevalent", says Corrons.
