What is modem hijacking?
Modem Hijacking is a type of fraud that takes place over a dial-up modem while you are on the internet downloading a file or in some cases, accepting certain terms and conditions. While your computer is downloading the information, the hijacker takes control of your modem and starts dialing international locations. Usually the first thing the hijacker does is disable the sound on your computer so that you do not hear the modem dialing. Hijacked international calls will show up on your phone bill as dialed international numbers.
