Harnessing Large Language Models To Simulate Realistic Human Responses To Social Engineering Attacks: A Case Study, Mohammad Asfour, Juan Carlos Murillo

International Journal of Cybersecurity Intelligence & Cybercrime

The research publication, “Generative Agents: Interactive Simulacra of Human Behavior,” by Stanford and Google in 2023 established that large language models (LLMs) such as GPT-4 can generate interactive agents with credible and emergent human-like behaviors. However, their application in simulating human responses in cybersecurity scenarios, particularly in social engineering attacks, remains unexplored. In addressing that gap, this study explores the potential of LLMs, specifically the Open AI GPT-4 model, to simulate a broad spectrum of human responses to social engineering attacks that exploit human social behaviors, framing our primary research question: How does the simulated behavior of human targets, based …

Asymmetric Secondary Flows Above Geometrically Symmetric Surface Roughness, Wen Zhang, Xiang Yang, Xiaowei Zhu, Minping Wan, Shiyi Chen

Mechanical and Materials Engineering Faculty Publications and Presentations

The mean flow behaviour of a turbulent boundary layer over rough walls is expected to exhibit symmetries that govern the flow dynamics. In particular, when roughness elements are arranged in a spanwise symmetric manner, the mean flow above them should also exhibit spanwise symmetry. This symmetrical consideration has garnered substantial empirical support. We conduct direct numerical simulations (DNS) of flow over aligned cube arrays to test such symmetry considerations further. We vary the surface coverage density from 0.25 % to 6.25 %, and employ an averaging time of about 100 large-eddy turnover times, which is longer than the typical averaging …

Beyond Consumer Protection: Standardized Stablecoins Disclosure As Information Infrastructure, Shuping Li

Brooklyn Journal of International Law

This article argues for standardized disclosure for stablecoins regulation. Information disclosure has long been considered a primary tool for consumer protection. Stablecoin issuers should disclose honestly and responsibly about the qualification of themselves, as well as the value, quantity, and operational mechanism of their stablecoins. Such disclosure can prevent issuers from taking advantage of information asymmetries for consumer exploitation or fraud. It is then up to the consumers to make informed investment or consumption decisions. More importantly, this paper argues that the fundamental role of information disclosure is to form a knowledge base for financial regulation and policymaking. The importance …
