The Download: supercharged scams and studying AI healthcare

Cybercriminals are increasingly using LLMs (large language models, AI systems trained on massive amounts of text) to launch faster and cheaper attacks, including phishing emails (deceptive messages designed to steal information), deepfakes (AI-generated fake videos or images), and automated vulnerability scans (tools that search for security weaknesses). Meanwhile, AI tools are being deployed in healthcare for tasks like note-taking, reviewing patient records, and interpreting medical images, but researchers still don't know whether using these tools actually leads to better health outcomes for patients.
