  "textContent": "Wifi imaging can see your body through blankets. Maybe you can find one that can block it, but when you test that, remember to test all the wifi ranges. Its unlikely that wifi imaging is good enough to get your phones pin. Graphene can scramble your pin, so unlocking under a blanket should work even if they are using it.\n\nAnother issue is tempest. If your not familiar, see GitHub - JuliaTelecom/TempestSDR.jl: Screen eavesdrop in real time leveraging SDR and pure Julia implementation ! · GitHub The docs say its because of the external connectors, so it may be harder with your devices. Worth testing.\n\nTried using a FLIR to detect some small electronics. It could detect a webcam, but only when it was not near another heat source, a monitor. A metal grate was enough to make it harder to see some electronics too. Most things showed up at about 1/2 meter, but some had to be 10 cm and were still faint. You should get some small mics and cameras and do your own tests.\n\nIf you have a laptop, things are harder. Typing pattern analysis has been around for a long time and its easy to hide mics. They might not even be in the same room. Blanket and type carefully. If your using a device with a touch screen, you may be able to set a scrambled pin instead. Or a screen keyboard if your patient enough. Keep this in mind when your typing out your secret recipe, too. This one is not worth testing. Just assume it.\n\nHave to mention radio scans, which some people do. The devices could store data for later pickup, or be programmed to turn on its radio after you leave. Even if it leaves the radio on, it could go through the smart tv or look like one.\n\nAs said above, treat the hotel room like the outside world or a busy airport.\n\nThis might be the app your thinking of. Needs a dedicated device. https://guardianproject.github.io/haven/\n\np.s. Velcroing fabric to the sides of your laptop to hide what your typing gets attention.",
