The campaign using Microsoft® Office® Outlook Web Access name boosts the infection rates

Our previous article about a recent malware dissemination campaign abusively using Microsoft® Office® Outlook Web Access name as coverage explained about the risk to infect your computer with 4 kinds of malware: Trojan.Spy.ZBot.EKF, Trojan.SWF.Dropper.E, Exploit.HTML.Agent.AM and Exploit.PDF-JS.Gen

Comparing the first half of January to the same period of the previous month (December, 1, 2009- December, 15, 2009), the total number of the infected files increased with almost 60%. When compared to the last half of December, the first half of January revealed a growth of corrupted files by 25%. The most affected countries by Trojan.SWF.Dropper.E between January 1^st and January 13^th are:

Data provided by BitDefender's Real-Time Virus Reporting System give an idea about the spreading of Exploit.HTML.Agent.AM: in the United States, the number of infected files increased in the first half of January with 10%, while in Spain this number got bigger with more than 400%, when compared to the last half of December.

BitDefender datasets also indicate a growing trend of Exploit.PDF-JS.Gen. The first two weeks of January showed that the most affected systems pertain to the United States, Spain and Canada.

In order to stay safe, BitDefender recommends you to never follow links inserted in messages from unknown contacts as well as to install and update a complete antimalware software solution.
