It was Christmas last year when LG was among the first to present the 6G network. Obviously, this has arrived (still unofficially) as the successor to the current 5G network. This new technology enables ultra-fast data transfer rates up to 1 TB per second. But what if we told you that scholars have managed to "hack" a 6G network using a simple one sheet of paper. It really happened and we explain how in detail.
Let's not joke: an experiment managed to divert the range of a 6G network using a sheet of paper and a laminator
The researchers of the Rice University and Brown University issued the results of an unusual sixth generation mobile network security experiment. As it turned out, in order to pick up the signals transmitted in them, it would not have been necessary to create expensive equipment: rather, it was enough to show a little ingenuity and have a sheet of paper at hand.
During the study, the engineers found that a 6G wireless network signal transmitted to a frequency of 150 GHz it can be partially intercepted using what is called metasurface. Scientists used a simple sheet of office paper as a "hacking" tool applied symbols in the shape of the letter C., made of tinfoil and arranged in a certain order.
After having "inserted" these shapes on the sheet with the help of a laminator, the researchers obtained a sort of antenna array capable of reject part of the signal. This allowed the data to be transmitted to third-party equipment. According to the authors of the experiment, one such metasurface it can be masked with a regular sheet of paper, which it will make it much more difficult to find the source of a data leak in case of a hacker attack.
For obvious reasons, the researchers did not publish the outline of this experiment. They noticed that with their work they wanted dispelling the myth about the safer nature of 6G networks (and in general those of the new generation) that transmit high frequency signals. It is possible that if equipment manufacturers become aware of the possibility of a hacker attack, they will be able to develop prevention systems interception of data and integrating it in advance into new network equipment.
