BitDefender Announces Top Ten E-Threats, Trojans Dominate

According to BitDefender's September 2009 E-Threats Report, the ten most prevalent Web threats for the month include three trojans that topped the list, contributing 25% of all contaminations, as reported by Ajax.sys-con on October 1, 2009.

The company's Top Ten E-Threats List for September 2009 is list of top malware samples in a descending order, detected by BitDefender's researchers during the month.

Of these malware samples, the first one is Trojan.Clicker. It is a tool to infect files that malware creators use while making key generators, racks, and popular software codes. The Trojan accounted for 10.98% of all contaminated files.

Placed second is Trojan 'Wimad', a general malware associated with trojans using Autorun function. This Trojan contributed 9.58% of the total infections during September 2009. Thereafter, the third place went to Trojan Clicker, an adware that contributed 5.52% of all contaminations.

Further, Conficker occupied the fourth place. BitDefender detected the worm as Win32.Worm.Downadup.Gen, with almost 5.5% of infections identified in September 2009.

Another exploit, which abuses a security flaw associated with the manner in which certain editions of Adobe PDF Reader perform parsing of embedded JavaScript, has revived and taken the fifth position.

Additionally, Exploit.JS.Y a sinister JavaScript that normally lies on malicious or compromised websites is at number six, making up 3.44% of all contaminations.

It is reported that a malware that BitDefender has been detecting for long has reappeared on the company's September Top Ten list. This malware, dubbed Win32.Sality.OG, has apparently fallen from position five to seven, accounting for 3.44% of contaminations. It also appears that this encrypted code, which is polymorphic in nature and infects files, is ready to make an extremely lengthy cyber-crime career.

Additionally, two other e-threats that exploit Autorun vulnerability in Windows (older editions) namely Trojan.Autorun.AET and Worm.Autorun.VHG occupy No.8 and No.9 spots respectively. Interestingly, Worm.Autorun.VHG is a downloader that disseminates the popularly known Conficker (aka Downadup).

Lastly, on No.10 position, Trojan.Skintrim.HTML.A, an HTML page that's normally seen with the Navipromo adware application, made up 1.29% of all contaminations.
