More Information
Sophos's anti-virus products include proactive protection technology, which can defend against new threats without requiring an update. Sophos customers have been protected against Troj/Ranck-BO (detected as Troj/Ranck-Fam) since version 3.89.
Troj/Ranck-BO is a proxy Trojan for the Windows platform.
In order to run on system start, the Trojan creates the following registry
entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
vXCXssdss
<path to EXE>
Troj/Ranck-BO chooses a random port in the range 10000 to 39999 to listen for incoming http requests. The Trojan then attempts to contact several remote sites to register itself with a remote user.
