I've received from Symantec a release with information on virus threats for the month of October 2003. According to Symantec Security Response these are the top 10 virus worldwide and in the Asia Pacific region:
GLOBAL TOP TEN THREATS
ASIA PACIFIC TOP TEN THREATS
There are several trojans that make it into the top ten malicious threats list for October including Trojan.Bootconf and Trojan.PWS.QQPass.E. A trojan is a program that neither replicates or copies itself but does damage or compromises the security of the computer. Typically, it relies on someone emailing it to a user – it does not email itself.
Trojan.Bootconf is a trojan Horse that modifies the TCP/IP settings to point to a different DNS server. It will also change your home page and search page in Internet Explorer to connect to out.true-counter.com.
Trojan.PWS.QQPass.E is another variant of the Trojan.PWS.QQPass family. It is a password-stealing Trojan Horse that steals passwords and user information. The Trojan is a Visual Basic application that requires the presence of Microsoft Visual Basic run-time libraries for it to run.
Althought there are currently no virus for the Windows Mobile platform and only a few proof of concepts developed for the Palm OS, it's important to be aware of the possibility of this happening. Geekzone reviewed the Symantec Antivirus for Handhelds before.
