Jeffrey Pawlick and Quanyan Zhu Deception plays a critical role in many interactions in communication and network security. Game-theoretic models called “cheap talk signaling games” capture the dynamic and information asymmetric nature of deceptive interactions. But signaling games inherently model undetectable deception. In this paper, we investigate a model of signaling games in which the...

Ransomware victims have paid out more than $25 million, Google study finds
Ransomware victims have paid more than $25 million in ransoms over the last two years, according to a study presented today by researchers at Google, Chainalysis, UC San Diego, and the NYU Tandon School of Engineering. By following those payments through the blockchain and comparing them against known samples, researchers were able to build a...

Google ransomware tracking finds vicious infection cycle
Ransomware surged last year, becoming a multi-million dollar business that’s so profitable it’s creating a “vicious cycle” of ever-increasing attacks, say researchers at New York University [Tandon School of Engineering] and Google who tracked the criminals’ payment networks. … The findings suggest that even though the last two large ransomware attacks, Wannacry, and Petya, did...

MINIMAX GAME-THEORETIC APPROACH TO MULTISCALE H 1 OPTIMAL FILTERING
Hamza Anwar and Quanyan Zhu Sensing in complex systems requires large-scale information exchange and on-the-go communications over heterogeneous networks and integrated processing platforms. Many networked cyber-physical systems exhibit hierarchical infrastructures of information flows, which naturally leads to a multi-level tree-like information structure in which each level corresponds to a particular scale of representation. This work...

A Dynamic Game Analysis and Design of Infrastructure Network Protection and Recovery
Juntao Chen, Corinne Touati, Quanyan Zhu Infrastructure networks are vulnerable to both cyber and physical attacks. Building a secure and resilient networked system is essential for providing reliable and dependable services. To this end, we establish a two-player three-stage game framework to capture the dynamics in the infrastructure protection and recovery phases. Specifically, the goal...

Optimal Secure Multi-Layer IoT Network Design
Juntao Chen, Corinne Touati, Quanyan Zhu With the remarkable growth of the Internet and communication technologies over the past few decades, Internet of Things (IoTs) is enabling the ubiquitous connectivity of heterogeneous physical devices with software, sensors, and actuators. IoT networks are naturally multi-layer with the cloud and cellular networks coexisting with the underlaid device-to-device...

Delta Air Lines tries letting passengers use fingerprints as boarding passes
Where’s your boarding pass? Forget it. Delta Air Lines is letting some passengers board planes with just their fingerprints…“With a password, you can just change it and move on with your life. You can’t do that with fingerprints,” said Nasir Memon, a professor of computer science at New York University’s Tandon School of Engineering.
