The paper proposes a taxonomy of 38 capabilities for social media intelligence and an LLM-based multi-agent pipeline that profiles users and predicts their susceptibility to personalized engagement, with reported F1 of 97.3% for extraction. Its dual-use character matters for AI readers: the same LLM profiling that supports defenders' exposure audits also lowers the cost of tailored social engineering. Expert validation (Fleiss' κ = 0.92) and comparisons to rule-based and NER baselines are the claims to check, since the evaluation rests on real participants' public data.
Social-HUMINT: An LLM-Augmented Unified Framework for Measuring Social Media Exposure
arXiv:2610.31573v1 Announce Type: cross Abstract: In the post-API landscape, social-media profiling has become inexpensive and automated: Large Language Models (LLMs) can extract structured information from unstructured content and deduce attributes users never disclosed. A person's true exposure is not what they post but what can be inferred from it. As these practices become routine, exposure to social engineering attacks becomes an operational certainty, demanding a shared framework for assessment and mitigation. We make this exposure measurable by quantifying how accurately a target can be profiled, and how far that profile enables social engineering attacks. Because no existing model fully spans this continuum, we unify Social Media Intelligence (SOCMINT) and Cyber Human Intelligence (Cyber-HUMINT), two individual-focused disciplines that evolved separately, into a single doctrine-grounded taxonomy of 38 capabilities across the Cyber Threat Intelligence lifecycle, where user profiling bridges passive collection and active engagement. Domain experts validated the taxonomy (Fleiss' $\kappa$ = 0.92). We operationalize its core path (extraction, inference, and susceptibility assessment) as an LLM-augmented multi-agent pipeline, evaluated on real participants' public data. Susceptibility is assessed indirectly: the pipeline predicts how each target would rank personalized engagement options, matching their actual choices significantly above chance. This ranking capacity captures the personalization on which tailored attacks depend. The underlying profiles are accurate: extraction reaches F1 = 97.3%, and inferred attributes score 4.73/5, both far above rule-based and NER-based baselines at negligible cost. The framework augments security analysts' tradecraft rather than replacing it and enables defenders to gauge their own exposure before an adversary does.
