My friend checked into a hotel with his girlfriend, ran a single script in Claude Code, and found out in 90 seconds that a hidden camera was running right behind the bathroom mirror After what he told me, neither of us even unpacks a suitcase in a hotel or an Airbnb anymore until a laptop by the door finishes one full sweep One prompt runs a 5-stage audit strictly in read-only mode: -> Wi-Fi radar: scans the local network via nmap, resolves manufacturers from MAC addresses, and instantly flags hidden cameras and ports streaming continuous video -> Bluetooth interceptor: listens across the room via the bleak library for unknown AirTag, Tile, and SmartTag trackers while spotting hotel locks on ancient firmware that open from the hallway -> Spyware detector: audits your phone against the open-source Amnesty MVT toolkit and exposes hidden iconless processes quietly leaking your location or mic audio -> Optical lens sweep: if the hotel isolates guest devices on the network, the agent walks you step by step with a flashlight across every bathroom mirror, vent, and angle facing the bed -> Priority report: builds one clean table ranking the risk level of every suspicious device and tells you the exact next move: from demanding another room to calling the police The agent never logs into anything, never hacks foreign devices, and translates 500 lines of raw network traffic into plain English in 2 minutes I would rather spend 2 minutes with an open terminal in the hallway than spend the whole trip being watched The full sweep prompt is below, just copy and paste ↓ Bookmark this post before your next check-in
