Trojans Dominate Sunbelt’s Malware Report for December 2009

One of the leading Windows security software vendors Sunbelt Software declared the ten most rampant malicious threats of December 2009 in the first week of January 2010.

As per Sunbelt Software ThreatNet statistics, in December 2009, the malware scenario looks extremely identical to November 2009. Both in November 2009 and December 2009, six out of the top ten malware detections were Trojans.

The most prevalent malware threat for December was found to be Trojan.Win32.Generic!BT, a standard discovery for Trojans, which constituted 18.69% of malware detected in that month. It is a downloader Trojan related to scareware. The Trojan had been the leading malware detection in November 2009 also.

The report claimed that Trojan-Spy.Win32.Zbot.gen (6.23%) acquired the second place. The Trojan abuses flaws in the system to infiltrate into users' computers to hack their privacy.

The third position belongs to Trojan.Win32.Generic!SB.0, which accounted for 4.09% of the malware detected in December 2009. This Trojan is a common detection for password-stealer Trojans, which install keyloggers that track all the keystrokes and finally send this data to remote malware purveyors who operate that Trojan.

As per the report, Exploit.PDF-JS.Gen (v) (3.31%) is on the fourth place in the list. The exploit conceals itself easily, thereby evading any of the usual scanning processes.

The fifth place is occupied by Trojan.ASF.Wimad (v) (2.42%). The ASF/Wimad family comprises of malevolent Windows Media files, which are able to receive commands from a remotely placed web server. They are generally developed or installed by another malware.

Fast Browser Search (2.40%) ranks sixth in Sunbelt's list. It is an adware spyware that sporadically contacts predetermined isolated servers and displays spontaneous commercial ads. This malware threat can stealthily update itself through the Internet.

Further, Trojan.Win32.Malware (2.23%) stands at the seventh position, followed by INF.Autorun (v) (1.62%), BehavesLike.Win32.Malware (v) (1.18%), and Trojan.Malware (0.94%) are on eighth, ninth and tenth positions respectively.

Apart from these, some of the most malicious web searches in December 2009 included: "Brittany Murphy" (leading to redirect websites selling rogues), "New Year's Parades", "Tiger Woods car crash" (sites offering videos with Trojan-laden video viewers), "Tiger Woods rumors", and "chromium os download" (leading to rogue download websites).
