Wireless signals are part of a technology that is constantly used to better control our devices and avoid wiring. However, despite the great benefits it brings, it is also the perfect target for cyber attacks.
For this reason, the great experts and manufactures have dedicated their resources to the creation of essential tools and articles for avoid all attacks that may target devices dependent on the wireless networks.
The Faraday case is one of the top rated items when it comes to protecting our privacy Y prevent information leaks. Here, we will explain how this cover works and its benefits.
What is a Faraday sleeve and what are these artifacts for?
New technologies have been developed with the purpose of eliminating wiring and limitations that these bring, being managed through wireless connections such as Wifi, 4G, NFC, Bluetooth and others. Although these technologies have brought many benefits to the world, they have also been guilty of new security gaps, allowing attackers to sneak through vulnerabilities to steal information and data more efficiently and quickly.
For this very important and delicate reason, the use of Faraday covers is recommended to protect our data from any wireless threat. Although, it also causes some disadvantages for our connection. The idea of Faraday covers is block all signals that our phones can receive, preventing the passage of any radio frequency emission, which limits access to any type of unwanted connection.
The material of which these covers are composed is copper or silver, which is covered with a fabric developed to completely wrap our device, with an electromagnetic shield. The sleeves get the Faraday name, for complying with the blocking of all electromagnetic steps. Its use is more frequent in the special forces of the military or aviation.
To refresh your memory a bit, Faraday’s cage or box is a box where the walls prevent the passage of any electrical wave or impulse, where the internal conductor is null, completely canceling the external fields the same. In other words, the cage positively charges the external part, removing the load from the internal area. This is because the conductor is polarized, so that it forms a narrow and thick electromagnetic field, where the sum of both fields equals zero.
Why are Faraday covers necessary to protect my privacy? Benefits
Faraday’s covers they have been very important from the beginning of wireless threats, and can bring us a great list of benefits for our safety.
Below we will mention some of the great uses of this electromagnetic shield:
Protection of electronic equipment
All electronic devices are sensitive to interference, and more if in the place we are, more than one communication channel is handled by frequency waves, but with the use of a Faraday sheath, their sensitivity is eliminated.
Finding devices that emit radio waves
The issue of interference it is very common in the city, but with the use of Faraday covers we can avoid these interferences. It does not matter how many wireless devices we have nearby, because there will be no type of interference.
Protect from unforeseen electrical currents
If we have sites that generate large electromagnetic pulses or circuits near our devices, we simply have to make use of the Faraday covers and isolate all that conductivity, protecting our mobile equipment.
Signal block
At other points, we can also prevent information leakage when our equipment is idle, completely avoiding data extraction. Faraday’s covers prevent the passage of any type of signal, so we will have a guarantee that no one can access our data or track our location.
Forensic work
If you want to do forensic work, make use of Faraday sleeves to prevent the interception of data, or alteration of them. This is a trick that has been working, because Black Hackers try to damage information when forensic investigations are carried out.
Protect your data
The Faraday bag is used by many privacy maniacs, to protect the controls of the car, credit cards, mobile and all types of electronic devices.
How does a Faraday bag work to block my mobile signals?
The covers are very easy to use, since they simply we must introduce our device inside it to avoid the passage of signals. Its operation is simple, since the structure cancels the loads, to avoid the passage to the interior. Many of the people wonder why, when they enter some houses or buildings, they lose the signal of their mobiles.
The answer is simple: the structure of the building It contains so many beams that they function as a Faraday cage. In other words, the signs are intercepted by structures conductive materials, preventing the passage of electromagnetic waves. The same situation happens with the Faraday covers, since it covers the device so that the waves circulate around the metals, leaving the inner end completely null, or negatively charged.
At a mathematical, physical and chemical level, it is known that the energy obtained by waves dissipates in structures, where the sum of negative and positive charges at both points vanishes. But well, we must bear in mind that you can’t trust yourself at all, since the Faraday covers prevent the passage of electromagnetic waves, but the voice is not, so if the device was in recorder mode the same will pick up all the sounds around you.
List of the best Faraday articles to protect my privacy
Exists more than one type of Faraday items that we can use to protect the privacy of our data. Next we will introduce you top five articles that you can use to prevent any information leakage on your devices.
Go for it:
Silent Pocket Wallets and Bags
The only way to prevent attackers from obtaining our credit card details is by using the wallets and bags that Silent Pocket offers us. We can find a wide variety of bags of this brand, highly recognized by the great security that provides our data. These wallets and bags have a metallic mesh underneath the decorative fabric that integrates RFID protection. The purpose of this, is to avoid reading the information that incorporates the NFC chips of our cards.
Silent Pocket Briefcases
These briefcases prevent the passage of any type of signal, allowing us to have information stored on our devices in a more confidential way. With the use of this briefcase, we will avoid communication by means of signals wireless, such as: WiFi, Gps; Bluetooth, RFID and NFC, which are completely bypassed. The size of these items turns out to be ideal for relocation of our 13-inch laptops and any other accessory smaller than that size.
Mission Darkness backpack
With only 300 euros we can buy our wonderful Mission Darkness backpacks, which offers us the opportunity to turn our devices into invisible and undetectable equipment.
It is integrated into its interior by a Faraday bag that isolates any signal, regardless of the force with which it is sent. Its size it is perfect for storing and moving any type of device, including laptops, or tablets. It is an article widely used by professional journalists, since they avoid the extraction of information, guaranteeing files completely confidential and no leaks.
TitanRF Faraday fabric
This fabric guarantees total isolation from signals, blocking the waves even a whole room, thanks to the fact that it can be distributed and positioned anywhere. The use that can be given to it, is limited by your imagination. It is highly recommended when we want completely safe spaces free from attacks by frequency waves. Although with her connection cannot be blocked by 4G signals.
TitanRF Faraday tape
Couldn’t escape our list, Faraday’s great duct tape, recommended by the great ability to isolate all signals, And like fabric, there are no limitations to its use. We can cover any device or surface with it, and prevent access from almost any type of wireless signal. Its disadvantage occurs when there are strong signals, however it is an excellent option to become invisible.
