A program that is often used to maliciously redirect Internet connections. When used in a malicious way, it disconnects the legitimate telephone connection used to connect to the Internet and re-connects via a premium rate number (1-900 numbers). Often, the first indication a user has of this activity is an extremely expensive phone bill, as the victim (account holder) is being charged for the amount of time connected to the premium rate number.
