Why should you wrap your car keys in foil?

"High-tech threats are becoming more sophisticated and diverse," said Holly Hubert, a former FBI cybersecurity expert. "It's not difficult for hackers to copy the code from a car key."

Hubert believes that the best way to keep your car keys safe is to wrap them in aluminum foil or silver foil. While this is not ideal, it is the cheapest way to help you prevent the risk of high-tech intrusion.

"Cars are always waiting for a signal from the key," Hubert explains. Hackers can buy legitimate devices that can amplify the signal from the key to copy the access code to the car.

However, with cheap metal protective shells that can block electromagnetic fields, completely isolating the device from connecting to the telecommunications network, hackers will not be able to access wireless means, and will not be able to capture signals from the key."

As CEO of GlobalSecurityIQ, Hubert recommends that users buy Faraday bags, which are also made of thin metal linings, to protect car keys from the risk of theft.

Moshe Shlisel, CEO of GuardKnox Cyber ​​Technologies and a veteran of the Israeli Air Force, recently met with major automakers such as Mercedes-Benz, Porsche, Audi, and Volkswagen to research controlling cars through the use of smartphones.

“Automotive security vulnerabilities are an industry-wide issue,” Shlisel said. “Automotive companies need to find ways to implement security features at every stage of design and manufacturing so that no one can replicate the communication between the key and the car.

Keeping the key in a small box that can be wrapped in aluminum foil or silver is only a temporary measure."

Cyber ​​security experts say that "cracking" car keys can also lead to the leakage of personal data and many other important information.

Clifford Neuman, director of the USC computer systems security center, pointed out that millions of users now carry credit cards in their vehicles.

"This is the reality of a wirelessly connected world where we can unlock our car doors with a click of a button remotely, and anything can go wrong," Neuman added.
