Modem Hijacking is a form of “high-tech cramming*” that can potentially cost a consumer hundreds of dollars and could happen if you use a dial-up service for Internet access. The most common way this occurs is when the consumer visits a Website, clicks in a “pop-up” window, or opens an e-mail which downloads a dialer program or virus into the user’s computer. The program or virus then disconnects the modem from the local connection number and reconnects it to an expensive long distance number (such as a “900” or international number). The consumer frequently does not find out about the problem until receiving his or her telephone bill.
