Term Definition
phone fraud
Phone fraud or telephony fraud encompasses dial-through-fraud, toll fraud and phreaking. It is perpetuated by international organised crime gangs who can earn vast sums in revenue from the fraud. Thieves exploit weaknesses in telephony systems - PBXs in organisations of all sizes - so that they are able to make outbound phone calls through the system with the bill being paid by the victim organisation. The crime gangs either dial premium rate numbers under their control or sell the cut-rate minutes online.
