Hi,
I recently came across a program called "BoSniffer.zip" that the
author claims will "block key points in the registry from BO as well as
search for existing installs of the backdoor."
Close examination has revealed that this is actually a BO server
with the "SpeakEasy" plugin installed. If you run "BoSniffer.exe", the
BoSniffer executable (read: BO Server Trojan w/ SpeakEasy) will "attempt
to log into a predetermined IRC server on channel #BO_OWNED with a random
username. It then proceeds to announce its IP address and a custom
message every few minutes."
This program, "BoSniffer.zip" is currently being widely distributed
as a "cure for Back Orifice infections". It is probably being distributed
with other software packages and with other names too. Listed below are
relevant details about this program.

You get the idea by now, hopefully.
