Worm.Downadup is a primary malware threat for SE Asia

by CXOtoday Staff    Oct 05, 2010

MalwareThe quarterly top e-threats in SE Asia are the immediate effect of PC users not updating and upgrading their operating systems and antivirus solutions, on the one hand and not scanning their removable devices, on the other hand.

The first place in the quarterly chart for SE Asia is taken by Trojan.AutorunInf.Gen, with a percentage of 8.85. This Trojan is constantly amongst the most “popular” e-threats as it easily spreads via removable devices and Windows shared folders. The Windows Autorun is intensively exploited by malware authors to force the execution of dangerous files located on infected USB drives.

Malware top for July - September 2010

Three out of five top places in this quarterly chart are taken by the notorious Downadup family representatives: Win32.Worm.Downadup.Gen, Win32.Worm.Downadup.B and Win32.Worm.DownadupINF.Gen, responsible for 6.30 percent, 5.36 percent and 2.12 percent, respectively. They too make use of the autorun feature and that is why they usually appear in the malware distribution charts alongside Trojan.AutorunInf.Gen. Computer users should always scan external devices especially after having plugged them into public computers such as those available in copy shops and libraries. Plus, computer users should know that, since Microsoft has patched this vulnerability in Windows Vista and Windows 7, they only need to update their operating systems and antivirus solutions in order to stay safe.

Occupying the fourth place, with 2.35 percent of the total amount of malware in SE Asia, Trojan.Generic.4338773 is a newcomer with great “negative” potential. This is a generic detection for cracks and keygens targeting various AV products. Trojan.Generic.4338773 has seen a significant boost these past few weeks and it is expected to spread even further.
