[en] Paper: LLMs 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."
"Our results show that the practical #obscurity protecting pseudonymous users online no longer holds and that #threat models for online #privacy need to be reconsidered."
"We demonstrate that LLMs fundamentally change the picture, enabling fully automated deanonymization attacks that operate on #unstructured text at scale."
Note: also check paragraphs "Potential harms" and "Potential benefits".
