What is a Faraday Bag?

Faraday Bags: Building a Security Barrier for Your Wireless Devices

As wireless technology gradually integrates into home networks, car keys, and even front doors, we are more reliant on "remote connectivity" than ever before. While this marks technological progress, like most technologies, it also comes with risks. In modern life, these risks include remote hacking, RFID card cloning, and other forms of cybersecurity threats.

Faraday bags, named after the inventor of the Faraday cage, can block radio frequency signals from being sent to or received from electronic devices such as mobile phones, car keys, or laptops. Various sizes of Faraday bags are available on the market for different devices, helping you protect against cyberattacks targeting your important digital devices.

How does a Faraday bag work?

Smartphones and similar devices not only connect to phone networks via wireless signals but also have other wireless capabilities like Bluetooth and Wi-Fi (e.g., the 802.11b/g/n standard). Even with standard security features built into smart devices, they can still be vulnerable to external attacks that may alter, delete, or even add data to the phone or another device.

Similar in principle to the Faraday cage, a Faraday bag is a closed, sealed enclosure that relies on the material of the bag to block the transmission and reception of signals. This is especially important for seized devices — when the data contained in a device is to be used as evidence in court, a Faraday bag ensures that its contents have not been tampered with.

What are Faraday bags made of?

Faraday bags can be made from a wide variety of materials, the most common being multiple layers of different metals, such as copper, aluminium, and static-dissipative polyethylene.

Although sleeves are considered the most practical form, tests have shown that many materials offer inconsistent shielding performance across different wireless frequencies. As a result, some high-end Faraday bags use high-grade composite materials combined with special conductive threads during the sewing process to ensure consistent shielding performance across all frequency ranges while keeping the bag reusable.

What are Faraday bags used for?

As mentioned earlier, one of the main uses of Faraday bags is to protect the integrity of information, typically by law enforcement and government agencies.

However, this is not the only application. Another important use is helping car owners protect against remote relay theft. For vehicles equipped with keyless entry systems, owners can place their car keys into a small Faraday bag (e.g., a car key shield) to prevent criminals from copying the key's signal or using it to open the vehicle.

In addition, some people known as "preppers" also store electronic devices in Faraday bags to protect themselves from hackers and unauthorised access, as well as from electromagnetic pulses caused by man-made devices or astronomical events — such pulses can damage electronic equipment.

As our reliance on wireless technology continues to grow, and as workplaces and homes increasingly depend on remote connectivity, protecting devices that are constantly online or searching for signals becomes ever more important. To safeguard your smart devices from unknown remote attacks, choose the right Faraday bag according to the type of device you own, adding a reliable barrier to your digital life.
