Fiber Optic Cables Turned Into Hidden Microphones
Fiber optic cables running through your walls can be turned into hidden microphones that record every word spoken in the room. This is not a theory anymore. Researchers from Hong Kong Polytechnic University published a fully working attack at the NDSS Symposium in February 2026, and the results are going to change the way a lot of people think about what is running through their walls. 😏
I refused to get fiber optic internet installed at my house. Call it a security instinct. Everyone around me thought I was being paranoid. Turns out that feeling was right.
