AI Deanonymizes Anonymous Accounts With 90% Precision for $1–4
- —AI correctly identified 226 of 338 anonymous Hacker News users, or 67%
- —At 90% precision against a pool of 89,000 candidates, the method caught about half of true matches
- —Each deanonymization costs $1–4 and requires no breach or insider access
- —In a test on 125 scientists, AI identified at least 9 people from how they described their work
Why it matters: Practical online anonymity no longer holds: a leaked identity can become a real-world address without any breach, a critical risk for crypto holders after a wave of kidnappings.
