There was an easy way to protect equipment from physical hacking. All you need is radio waves

The team says that even if the slightest attempt at physical hacking occurs, for example, to install

bookmarks, the system will raise the alarm. It is noted that the method is very simple to implement.

During the work, the researchers used two small antennas and a special radio signal. It's like creating a kind of digital fingerprint for every electronic device.

The result is a system for detectingphysical hacking, which has small transmitting and receiving antennas. The radio signal is reflected from the electronic components, then it is received by the receiving antenna as a digital fingerprint. Any attempt to install something superfluous in the system distorts the signal and reports interference.

In a series of experiments, the researchers showed that the system reliably responds to how a 0.3 mm thick needle penetrates a working computer case to a depth of 1 cm.

“Therefore, in practical application, it makes sensethink carefully about where to place the antennas. They should be located as close as possible to components that require a high degree of protection, ”the researchers said.
