Peter, I think what you seek is Challenger TT http://www.cpscom.com/gprod/challtt.htm Happy War Dialing if that was not the case :) Stephan "M4phr1k" Barnes Stephan.Barnesat_private http://www.m4phr1k.com -----Original Message----- From: Peter Van Epp [mailto:vaneppat_private] Sent: Wednesday, March 19, 2003 10:50 AM To: pen-testat_private Subject: modem protective device? While not strictly on topic, assuming they are still made this may be of interest to those of you concerned with modems and wardialing. Some 20 years ago in a previous life I had a modem protective device (a modem condom!) which fronted the modem on the phone line and when dialed supplied a sythisized voice which asked you to "enter your code". You then fed it a code via DTMF and it (if it liked your code) faked ring to the attached modem and then passed the call through when the modem answered. This is of course very good protection against war dialing (which is the pen-test relevance that I hope will get this through moderation :-)), since the war dialer gets a human (or semi human) voice not modem tones. The problem is that several google searches on "wardialing modem protection" in various combinations turn up lots of articles on war dialing but no references that I can see to the product that I want again. Does anyone know a source of such a product? I find it hard to believe that such a useful device has died out! Peter Van Epp / Operations and Technical Support Simon Fraser University, Burnaby, B.C.
