Top 10 most malicious software in July 2006
Security firm Sophos has announced the list of Top 10 most dangerous viruses in July, whereby Netsky-P continues to be the most powerful virus spread via email.
Since being discovered for the first time in March 2004, Netsky-P has consistently been a virus capable of spreading vigorously and causing the most damage to users via email.
Compared to the previous month, the rate of notification of Netsky-P infection sent to Sophos increased by nearly 3% - from June 16.7% in June to 19.3% in July.
Other locations in the list do not have many major mutations. Only Bagle's appearance was in third place with 9.3% reporting the virus infection rate. In June, Bagle was just a "wet foot" who entered the rankings. But just one month later, it was number three.
This is a sign of the recent growth of the virus strain. This is a keylogg worm that aims to steal sensitive information on infected systems. The strong growth of computer worms shows the trend because of the financial motivation of hackers.
The Sophos report also said that the percentage of e-mail messages containing malware in July has dropped significantly. The current rate is for every 1 in 222 (equivalent to 0.45%) of the email to contain viruses, while the average of the first 6 months is 1 in 91 emails (equivalent to 1.1 %).
In July, Sophos found a total of 3,715 new security threats, bringing the total number of detected and eradicated software to 184,007. Most of them - about 87% - are Trojans, while computer viruses or worms make up only 13%.
