Many free AI tools are trained or improved using the data users feed into them, which means anything sensitive typed into a public chatbot — passwords, client data, unpublished business plans — could resurface somewhere you don't want it. Reading a tool's data policy before pasting in sensitive information is worth the thirty seconds it takes.
Voice cloning and deepfake technology have also made old verification habits less reliable. A call that sounds exactly like a family member or a boss's voice is no longer proof of who's actually speaking, which is why security teams increasingly recommend a separate verification step — a callback, a code word — for anything involving money or sensitive access.
The basics still matter most: unique passwords with a password manager, multi-factor authentication everywhere it's offered, and healthy skepticism toward urgent requests, whether they come from a suspicious email or a suspiciously perfect voicemail.
