[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".

@vortex_egg There's a very long and substantial history of people adopting pseudonyms, nicknames, pen names, stage names, nommes de guerre, etc., for any number of reasons.

Some you're no doubt aware of, many you're quite likely not. ("Willy Brandt" was a particular surprise for me.)
