A unified framework for measuring how much a social media profile exposes you, with 38 capabilities and LLM profiling at 97.3% extraction F1

AspireAI community · arXiv
As social media profiling becomes routine, the authors argue the real exposure is not what a person posts but what can be inferred from it, and they make that measurable. They unify Social Media Intelligence and Cyber Human Intelligence into a single doctrine-grounded taxonomy of 38 capabilities across the Cyber Threat Intelligence lifecycle, validated by domain experts at Fleiss' kappa of 0.92, with user profiling bridging passive collection and active engagement. They then operationalise the core path of extraction, inference and susceptibility assessment as an LLM-augmented multi-agent pipeline evaluated on real participants' public data, where extraction reached F1 of 97.3% and inferred attributes scored 4.73 out of 5, both far above rule-based and NER-based baselines at negligible cost. Susceptibility is assessed indirectly by predicting how each target would rank personalised engagement options against their actual choices. The authors position the framework as augmenting security analysts' tradecraft rather than replacing it, and it carries obvious dual-use risk given that it demonstrates profile extraction from public data.

THE BIG PICTURE
A FRESH PERSPECTIVE
Research
One distance function matched sparse-autoencoder features across layers and compressed feature circuits into supernodes
Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
