BitDefender Announces Top Ten Malware
BitDefender, provider of data security programs and anti-virus software, declared its list of top ten malware threats for August 2007. E-mail threats like the Storm worm or Peed Trojan and the traditional Netsky.P virus topped the charts. They accounted for 24.7% of all threats detected.
According to BitDefender's analysis, the Trojan downloader occupied the third place accounting for 19.06% of total threats while Netsky was on the fourth place with 5.89%. The Pandex Trojan was among the top five rankings as it was responsible for 2.54% of malware detected.
The most prevalent malware in 2007, so far, is Trojans. Of these, the class of behavior-based Trojan malware was second on the top ten chart. Behavior-based trojans refer to those items of malware that have Trojan characteristics. These are proactively spotted and detected before assigning names and signatures to them.
BitDefender Labs detected another notable malware, the Win32.Sality.M virus, in the first six months of 2007. This is the single true virus to be part of the list. While the mass mailer Bagle virus is an important vector for the dissemination of the extremely dangerous polymorphic virus, it did not make to the August list.
The widely used Windows metafile rendering malicious code that emerged in December 2005 and which was fixed in early January 2006 reappeared to hold the second rank in the top ten-malware list accounting for 21.5% of the entire detections. The presence of computers that are still lying around un-patched is a matter to worry.
A rootkit named Trojan.Kobcka.A, that is a very sophisticated and most recent malware, is the only new threat in the August list of top ten, according to BitDefender Labs' August 2007 report. It is assumed that the rootkit conceals a mass-mailer virus.
The Trojan.Kobcka.A, which was responsible for 1.24% of total detections in August 2007 and which had managed to find a place in the top ten, indicates that there would be new variants of the malware ready to infect systems in the approaching months, said Viorel Canja, Head of BitDefender Labs, as published by darkReading.com on September 6, 2007.
