Large-scale online deanonymization with LLMs
We show that large language models can be used to perform at-scale deanonymization. With full Internet access, our agent can re-identify Hacker News users and Anthropic Interviewer participants at high precision, given pseudonymous online profiles and conversations alone, matching what would take hours for a dedicated human investigator. We then design attacks for the closed-world setting. Given two databases of pseudonymous individuals, each containing unstructured text written by or about tha…

Deanonimizzazione online su larga scala con LLM
Gli LLM possono essere utilizzati per eseguire una deanonimizzazione su larga scala. Con un accesso completo a Internet, il nostro agente può reidentificare gli utenti di Hacker News e i partecipanti ad Anthropic Interviewer con elevata precisione, dati solo profili e conversazioni online pseudonimi, un'operazione che richiederebbe ore a un investigatore umano dedicato. Progettiamo quindi attacchi per l'ambiente chiuso. Dati due d…
