Here’s something most people don’t think about when they’re chatting away with an AI: the chatbot itself can be the threat.
Not because AI is secretly evil. But because chatbots can be programmed — or manipulated — to extract your personal information in ways that feel completely normal. Like you just… volunteered it. Casually. In the middle of a friendly conversation.
Researchers at King’s College London studied exactly this, and what they found is kind of alarming: intentionally malicious AI chatbots can get users to reveal up to 12.5 times more personal information than a normal chatbot would. That’s not a small difference. That’s an enormous one.
The trick is trust. AI chatbots are designed to be warm, friendly, and helpful — that’s literally their job. But that same quality becomes a vulnerability. A manipulated chatbot acts friendly to build a connection with you, and then uses that connection to nudge you into sharing things you’d never hand over to a stranger on the street. Researchers described it as a “concerning paradox” — the very thing that makes AI feel safe is what makes it dangerous when it’s been set up wrong.
There’s also a second kind of attack worth knowing about. WIRED reported on a technique called prompt injection, where hidden instructions are fed into a shared AI system through external data — like a document you upload, a webpage the AI reads, or content from another user in a shared environment. The AI follows those hidden instructions without telling you. So even if you trust the chatbot you’re using, if someone else slipped bad instructions into the system, the AI could be working against you without either of you knowing.
This is especially relevant in multi-user environments — think shared workspaces, school platforms, or any tool where multiple people interact with the same AI. If someone else in that environment knows what they’re doing, they can potentially influence how the AI talks to you.
So what does this actually mean for how you use AI?
First: treat a chatbot like a stranger at a party, not like your journal. It can feel like talking to a friend — that’s by design — but don’t let that feeling make you overshare. Your home address, your schedule, your financial situation, your relationship drama — none of that needs to go into a chatbot prompt.
Second: if a conversation with an AI starts feeling weirdly personal or keeps steering you toward sharing specific details about your life, that’s worth noticing. Normal helpful AI doesn’t need to know where you live or what your passwords are.
Third: on shared platforms, be aware that the AI’s behavior can be influenced by inputs you never see. You’re not always the only one shaping the conversation.
