Forwarded From: Ken Williams <jkwilli2at_private> -----BEGIN PGP SIGNED MESSAGE----- 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.
