MessageLabs have detected a Trojan posing as a movie clip of yesterday's terrorist attack in London. The email containing this Trojan has been crafted so that it appears to be a CNN Newsletter which asks you to 'See attachments for unique amateur videoshots'.
When executed the attachment copies itself to %Windir%winlog.exe and modifies the Windows registry key 'HKLM/Software/microsoft/Windows/CurrentVersion/Run' so that it runs automatically on system start-up. The Trojan then attempts to obtain a list of the SMTP servers that your machine is configured to use and starts to use these servers to send large volumes of unsolicited mail.
