I just recently saw some interesting information on the subject of war-dialers and phone "hackers".... Supposedly there are people who use their personal computers to "hack" out 950-XXXX or 800 LD phone services.... I was just curious as to the reality of this and also the circumstances involved in doing such a thing (I'm sure you'd get into a LOT of trouble, no doubt!)... More importantly, what have the LD phone companies been doing on this matter? It seems that a while back someone had "hacked" my LD calling card. No doubt I was upset, but what can the phone company do to prevent such a thing? With all the info here on ESS and other sophisticated systems, do these devices provide "anti-hacking" routines?? I heard that many LD companies have a device called ANI? What is this? Also I heard that the rapid dialing of digits by wardialers also set off a "suspicious" activity flag.. Is this true?? I am new to this net and any information would be appreciated... It's quite interesting to see how the phone co really works when you make an ordinary call... Please send email to my unix address or post here.... Thanks in advance, George Wang Gwang@logic.nsc.com
