We are starting a series of posts covering surveillance/counter surveillance or offense and defense and the equipment used and thought of no better place to start than faraday bags.
Faraday bags are a very simple but important piece of defensive equipment that serves basically two purposes. Blocking signals from entering or escaping and device protection from outside EMFs.
They come in sizes ranging from small for your key fob for newer high end luxury cars to prevent cloning and car theft on up to full on back packs and suit cases for those needing to carry around lots of sensitive equipment. The most popular sizes though are for Phones, tablets, and laptops.
Faraday bags consist of a special fabric that blocks out 100% of wireless signals being either sent or received by what ever device you put in them. (or at least they should) you should always test your bags before you are needing to rely on them.
Some can also offer protection from EMP and other sources of EMFs that can damage your electronic devices if they are strong enough. This is where the protection category falls as well as they prevent anyone in the immediate area from connecting to your device, usually this is done over bluetooth.

There are many reasons you will want to use a faraday bag/pouch. Ones of those cases would be….
Privacy. Placing your devices in a faraday bag cuts off and keeps anyone or thing from connecting to your device with out your knowledge. This applies if you want to avoid being GPS tracked by apps or having your phone or device wifi/blutooth hacked. Another privacy related reason is that cities are starting to place blu tooth tracking nodes through out the city to track “traffic patterns” or so they say. These nodes connect to any device that enters their range and logs the information. Even if this is for traffic patterns it would not surprise me if this is used to look up who was in an area at a certain time when law enforcement needs too. Or in relation to our previous post when a rouge employee wants to track their girlfriend
