Is it possible for a home phone number to be utilised by hackers from an external source when the computer is switched off and the internal modem is still linked to the line? I know of a case where a residential number was utilised to dial an adult web page in the early hours of the morning when the computer was definitely switched off. The resultant time spent was registered on the person's phone bill at a time when noone in the house had been anywhere near the computer or the web site at any time. I look forward to your answers because I have been told that it can be done by malicious users. Incidentally, the line is a standard british phone line and not a cable line. Further to that, a dial-up connection was discovered in dial-up networking called "hearsayx" with the dial-up number being 5555555. This had never been created at all by the user. A full virus scan was done of the system with the latest definitions and nothing turned up.
