Top 10 malware threats of September revealed - QuartierLatin1968

GFI Software has today announced the top 10 malware threats for September based on analysis of virus scans from its VIPRE Antivirus and CounterSpy anti-malware tools, revealing trojans and a number of scareware as being the top threats for the month.

The GI VIPRE ThreatNet showed the Trojan.Win32.Generic!BT was the most significant threat, unchanged for a number of months. 23.54 percent of detections featured this malware, which was slightly down on previous months. August saw it at 25.11 percent, July at 29.08 percent, and June at 27.16 percent. 

The decrease could be seen as a good sign, but in reality it may be that the Summer months triggered an increase due to more people being off school and work using computers, and things are now stabilising again.

The second slot is held by another trojan, the Trojan-Spy.Win32.Zbot.gen, which attempts to steal passwords. It also had the same position last month.

The third rank is another trojan: Trojan.Win32.Generic!SB.0, climbing two places from rank five last month. It's also aimed at stealing passwords and works in conjunction with other trojans by installing keyloggers.

Trojan.Win32.Generic.pak!cobra took fourth place. INF.Autorun came in fifth. Worm.Win 32.Downad.Gen came in sixth. PlaySushi came in eight. Trojan.Win32.Malware.a came in tenth.

“These detections are evidence of the activities of botnet operators. They use their networks to pump out the spam that’s intended to infect machines,” said Francis Montesino, manager of the Malware Processing Team at GFI Labs.

Seventh and ninth places are taken up by scareware, Trojan.HTML.FakeAlert.e and FraudTool.Win32.FakeAV.gen!droppedData. These display false warnings to users to scare them into downloading fake antivirus programs, which are actually malware. This is a growing problem, playing on people's fears, and highlights the need for download safety awareness.

GFI also warned of a number of new malware threats that appear all the time.“We’re seeing a steady flow of new rogues too – one or two per week,” said Tom Kelchner, research centre manager at GFI Labs.
