         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.

    .QUIT Psssst...Speakeasy was told to shut down
    .NOTICE #BO_OWNED :Psssst...Speakeasy just started up
    You get the idea by now, hopefully.
