Fraud in Telephony Networks Telephone networks first appeared more than a hundred years ago, long before transistors were invented. They, therefore, form the oldest large scale network that has grown to touch over 7 billion people. Telephony is now merging many complex technologies and because numerous services enabled by these technologies can be monetized, telephony attracts a lot of fraud. In 2015, a telecom fraud association study estimated that the loss of revenue due to global telecom fraud was worth 38 billion US dollars per year. Because of the convergence of telephony with the Internet, fraud in telephony networks can also have a negative impact on security of online services. However, there is little academic work on this topic, in part because of the complexity of such networks and their closed nature in the past. This talk aims to provide a taxonomy of fraud in telephony networks and to help in understanding fraud better.
