Security vendor Kaspersky has just released the top 20 of the virus that plagued the Web last month. The results were not startling, with generic Trojan Email-worm.Win32.NetSky.q still leading in the Board. In fact, from a total of 20 malicious programs, 15 were Trojans. In regard to the countries with the most intense infected e-mail traffic, the United States holds the top position, followed closely by South Korea and China.
Since it is summer and fairly all those on holiday, relaxing in the sun, the virus statistics are similar to those of May. The three positions are still occupied by the Trojans, Netsky and Nyxem. What is interesting is that for some malicious software this is their first appearance in the top 20. Coming in at number 16 and 17 are two new invader program called Net-Worm.Win32.Nimda and Trojan-Downloader.Win32.Injecter.ga. The other new programs coming in at the bottom of the list: a WMF exploit ranks 19th and a Trojan called E-Worm.Win32.LovGate.w the 20th position.
The aforementioned Nimda worm is not new, it is only new in the top 20. It originally came out as of 2001, but has resurfaced and appears to be to make a pretty nice recovery. Nimda use every opportunity we can find to breed, this includes the infected e-mails, network devices, LAN vulnerabilities, the IIS server attacks. When the computer is infected, Nimda proceeds to create a guest user account and make it possible for everyone on the network to access data stored on your drives.
