AI allows hackers to identify anonymous social media accounts, study finds

Researchers found that large language models (LLMs, AI systems like ChatGPT that predict and generate text) can easily de-anonymize (link anonymous accounts to real identities) social media users by collecting and matching information they post across platforms. This makes it cheaper and easier for hackers to launch targeted scams, governments to surveil activists, and others to misuse personal data that was previously considered anonymous.
