282 iOS AI Apps Leak API Keys and Open AI Proxy Access in Network Traffic Study
Researchers tested 444 AI chatbot apps for iPhone and found that 282 of them, nearly two-thirds, exposed paid AI access through their network traffic.
In many cases, the path in was visible just by watching what the app sent: a plaintext API key, a reusable token, or a backend server that accepted requests with no key at all.
Whoever grabs it can send model requests on the developer's account,
