ESET Estimates Top March Threats

The top threats for March 2007 covered keylogging software, botnet installation and other dangerous malware, revealed ESET. The agency's ThreatSence.Net reports on statistics it collects from numerous computers all over the world that were detected with attacks. Based on that ESET's latest figures indicate that malware continues to exist as always.

March's statistics reveal that there is a fairly even distribution of the month's malware with the five on top having a difference of just half percent. The main purpose is obviously to steal personal information to make money fraudulently. Since no malware makes a clear leader on the top of the list of ten, it shows that their creators too consider multi-layered strategy as convenient to launch attacks just as the strategy helps for defense, said Paul Brook, managing director of ESET U.K. Net4now published Brook's comments on March 4, 2007.

In the March 2007 top ten threats the Agent.NCC Trojan accounted for 2% of all detections. The Trojan Win32/PSW.Agent.NCC was detected to employ keylogging to steal passwords. Win32/Nuwar.gen occupied the top spot accounting for 3.65% of detections. Netsky.Q was in the second place and Win32/TrojanDownloader.Agent.AWF in the third.

In February 2007, HTML/TrojanClicker.Agent.A was in the second spot with 3.63% of all threats. Next to follow was Win32/Nuwar.gen. And Win32/Adware.Ysiou was in the third spot with 3.14% detections. Bcs.org reported this in early March 2007.

In March 2007, the trojans included Win32/Adware.Boran with 1.55% detections, Win32/PSW.QQRob with 1.51%, Win32/Adware.Yisou with 1.46%, Win32/Perlovga with 1.36%, Win32/Medbot.HF with 1.19%, Win32/Nuwar.gen with 1.18% and Win32/BHO.G with 1.16% hits.

In February 2007, though Win32/Adware.Yisou was a completely new Trojan it topped as number one, commented Paul Brook. The Trojan is a keyword-lookup program that controls IE's search feature and lets users employ Chinese characters to conduct their search, making it a useful tool. But it delivers pop-ups that are hard to uninstall. Therefore, it is not popular with non-Chinese language users who may by chance install it. Bcs.org published this as news on March 7, 2007.

Win32/Adware.Yisou dropped from the first position in February to sixth place in March 2007, according to March's report.
