Technical Description:

The trojan reads from http://[BLOCKED]/wemail/index.php a custom script which it tries to interpret.
The script provides the following main actions:
- logon into an existing email account (@hotmail, @yahoo or @30gigs);
- read from http://[BLOCKED]/base.php coded information about an email to send (To:, Cc:, Subject:, Body:);
- decode the email and send it;
- try to create new email account(@hotmail, @30gigs, @google);

Email accounts have the following pattern:
- <Name1><RandNo1><Name2><RandNo2>@hotmail.com - swift3409494vlad45@hotmail.com
- <Name1><Name2><RandNo>@yahoo.com - ClaudiaWilder85@yahoo.com
