Last time I went to DefCon, the SLNT Bags were petty popular. I didn't buy one myself so I can't speak to their effectiveness, but if the DefCon crowd trusts them I think they're probably at least worth looking into.
I am not sure if I would trust a company that claims a glorified fanny pack will protect your health from EMF radiation.
Any chip packet (you know, like a Doritos packet) , or your fridge. Try a chip packet in the fridge, that should stop it.
Haven't tried the microwave, but maybe that's an option too.
I saw a speaker at Black Hat once break down some big failures in international espionage, and one instance he cited was CIA agents thinking they could use a Doritos bag as a Faraday cage.
What are you trying to accomplish? Prevent RFID tags in a wallet from being read?
Ah, you know, just throw a device in that communicates anywhere from 40 KHz to 40 GHz so that it never communicates until I take it out.
Keep my garage fob from going off, fuck with googlemaps, the works.
You can buy fabric that has metal threads, which works like a faraday cage and put it in a sock or whatever. TitanRF for example.
If you want a diy and cheap option.
I got like a whole square foot for 10 or 20$ years ago and it works like a charm.
The most reliable way to know if a Faraday bag works is to test it yourself - put your phone inside, call it, and if it doesn't ring or go straight to voicemail, it's blocking signals effectivley.
Well yes but in that case you have to keep buying and testing bags until you find one you like.
So, alternatively, I asked if anybody here has used or reccomends them.
