If you spend a lot of time on sites like Reddit or Twitter where
anonymity is usually a given, you might want to think carefully about
your posts. A new research paper shows that large language models
can be used to associate anonymous accounts with named public
accounts with startling regularity. In short, AI can dox you.
The researchers found that a relatively small amount of shared
information could let an automated system pin down your ID with a
high degree of certainty. If you're a member of r/movies subreddit, for
example, and you share ten of your favorite movies, your Reddit
account could be associated with a data leak from Netflix, complete
with your name, at almost a 50 percent success rate.
Of course doxxing has been a thing for almost as long as the web
itself, and this is nothing a regular snoop can't do, alone or in a group.
It's the automation of the doxxing process using LLM tools, and
deploying it across thousands or millions of accounts at a time, that
presents a real danger. And that's happening at the same time that
governments around the world are demanding ID age verification. The
status quo of a generally anonymous internet might be coming to an
end, so as always, be careful what you post.
