Simple Faraday Shielding

"Faraday Cage".......

The phrase invokes images of Gene Hackman's rouge NSA character from the film Enemy of the State, hacking away from the safety of his wire copper mesh "office". It also brings up thoughts of nuclear detonations and solar coronal mass ejections frying everything from televisions to the family car.

We'll save the intricacies of those scenarios for a later article. What I want to address today is basic RF (radio frequency) shielding in a practical sense. As I see it, there are four basic aspects to how we may use shielding, whether it be an RF blocking pouch for our phone or a grounded, sealed, galvanized trashcan for our spare equipment (post apocalyptic resupply of course). They are:

1. Preventing our device from being exploited 

2. Preventing our device from exploiting us

3. Preventing unwanted destruction of our device 

4. Protecting our health

These should all be pretty self explanatory, but lets touch on each real quick.

1. This could be anything from a hacker planting ransomware on your device, to the government tracking your messages and accessing your microphone and/or camera.

2. Your phone in particular, and your computers and tablets to some degree, are constantly reporting your whereabouts to your service provider and whomever they share that data with. With phones this can range from cellular tower triangulation to the more nefarious IMSI sniffers/spoofers.

3. This would likely only occur during a nuclear event that is very nearby or that triggered a carrington effect covering a much broader geographical area.

4.  Any medical practitioner will tell you - no amount of RF radiation is healthy for the human body. We are bombarded with RF of varying intensity all day long. It could be the cell phone pressed against our skull or the wireless router in our house blasting us day and night.

One could build an "RF safe room" in their home to mitigate some of the above. You can purchase rolls of the RF attenuating fabric online (same stuff that lines the phone RF pouches), but what might be more practical is to just paint the room. There is a company that produces an RF/EMF blocking paint that claims up to 30dB of attenuation per coat. LessEMF Paint markets the paint. Bear in mind that if you want this to be a "clean" room you will need to remove all light fixtures, outlets, switches and paint every surface (floors and ceilings).

Might be worth having a small office in your abode that is RF for thought.

Well, it has been an interesting couple of months in the world of privacy and cyber security. We had the "vault 7" leaks, then we just had the NSA's TAO hacking tools released into the wild for any and all to use. So now we don't have to be concerned only about nation-states wielding those kinds of tools, but potentially every criminal element out there. Many INFOSEC researchers have pointed out that this makes Windows vulnerable to a wide assortment of attacks. Ironically, their "fix" is telling everyone to upgrade to Windows 10!! An operating system that, near as I can tell, was built from the ground up to spy on you.....what a joke!

The GroundRod series of courses continues to grow in popularity as people around the country are realizing that no one will save them....they have to save themselves! We have a very full class coming up the end of April in Tennessee as well as a full class in northern Idaho in June. Here are some of the courses that are still open for enrollment:

* May 13-14          GroundRod 1   in Bend, OR

* May 27-28          GroundRod 1   in Fort Meyers, FL

* June 1-4              GroundRod 1 & 2   in CDA, ID

* June 17-18          GroundRod 1   in Eugene, OR

* July 14-17           GroundRod 1 & 2   in Buffalo, WY

* July TBA            GroundRod 1 & 2   in Prosser, WA

* August 11-14      GroundRod 1 & 2   in Scranton, PA

We also have a Gunfight Concepts Carbine 1 course in Central WA for June 10

You can register for any class by visiting the Store page and making a $100 class deposit, then emailing me with the requested course and date.

We still have a few SEPIO laptops and VERUS phones in stock with more on the way.
