An LLM Agent-based Framework for Whaling Countermeasures

Jan 21, 2026

This study addresses the growing threat of high-precision generative AI-powered whaling attacks targeting senior university personnel, for which existing defenses lack personalization and contextual awareness. The work proposes the first defense framework based on large language model (LLM) agents, which constructs individualized vulnerability profiles by mining publicly available information, identifies high-risk scenarios, and generates contextually coherent, interpretable, and personalized defensive strategies. By innovatively deploying LLM agents for whaling protection tailored to academic staff, the approach demonstrates in preliminary experiments its ability to produce realistic risk assessments and strategy explanations aligned with actual professional contexts. These findings validate the framework’s feasibility while also highlighting key challenges for real-world deployment.

Logarithmic scaling and stochastic criticality in collective attention

Jan 18, 2026

This study uncovers universal scaling laws and an underlying stochastic critical mechanism governing collective attention dynamics. By analyzing large-scale Wikipedia pageview data, the authors formulate a stochastic differential equation model driven by fractional Brownian motion and demonstrate that the logarithmic variance of collective attention grows slowly with the logarithm of time, deviating from conventional power-law behavior. They introduce a critical boundary defined by a single exponent ξ = H − η, which separates power-law growth from saturation at ξ = 0, thereby classifying collective attention as a non-Markovian process characterized by long-range memory and ultraslow dynamics. Integrating a Gaussian mixture model, the framework successfully reproduces the observed logarithmic variance scaling and accurately reconstructs the cumulative attention distribution, revealing a profound connection to aging dynamics in glassy systems.
