The GSU chapter of the ACM, in conjunction with the GSU Student Branch of the IEEE and the Computer Science Club, presents

Rise in Phone Fraud: Have You Secured Your Call Centers?

Dr. Payas Gupta
Senior Research Scientist
Pindrop Security, Inc.

In the past decade, technologies such as Voice-over-IP (VoIP) have converged telephony with the Internet. Technological advancements in VoIP have allowed fraudsters to mount successful voice phishing attacks by calling victims’ banks, insurance companies, retailers, government agencies, and emergency responders. Therefore, a massive shift is needed in the way we handle the security of our call centers and voice-based IOT devices. In conversations with our major partners, we have found that blended threats that utilize both the web and telephony channels have become a serious concern. Phone fraud is now so prevalent that it caused $14 billion in losses last year. We found a 79% increase just in retail fraud rates between 2014 and 2016, where one in 491 calls is fraudulent. This includes Card-Not-Present (CNP) fraud, account takeovers, cross-channel attacks, and reshipping fraud over the telephone.

Pindrop’s patented Phoneprinting technology helps call centers detect anomalous behavior for first-time callers and identify repeat fraudsters. We also developed Phoneypot, the first large-scale telephone honeypot for studying phone abuse. We believe Phoneypot provides us with new insights into telephony abuse and attack vectors that could threaten the online channel. The talk will also summarize insights that have been gained based on the analysis of Phoneypot-generated abuse data.

About the Speaker: Dr. Payas Gupta is a Senior Research Scientist at Pindrop. His primary research interests revolve around telephony security and the human aspects of security. He has won best paper awards for his recent work on a telephone honeypot (Phoneypot) at NDSS 2015 and on keystroke biometrics at NDSS 2013. His work has been published in top security conferences including CCS, Usenix Security, NDSS, RSA, and M3AAWG VTA-SIG. Some of the detection systems resulting from his recent research have been integrated into commercial products distributed by Pindrop, which specializes in phone fraud detection to protect enterprise call centers, and other various other robocall-blocking companies. Payas obtained his Ph.D. from the School of Information System at SMU, Singapore, in 2013 and a Bachelor of Technology in Communication and Computer Engineering from LNMIIT, India, in 2008. In 2011, Payas was a visiting scholar for a year in Carnegie Mellon University’s CyLab and Heinz College of Information Systems and Public Policy. Prior to joining Pindrop, he was a research scientist at New York University Abu Dhabi.
