Raspberry Pi realizes a mechanism to detect viruses from electromagnetic waves emitted by PCs and smartphones, and there is no effect on the inside of the computer

Identifying whether a computer is infected with a virus is typically done by installing software. However, a new external device with a mechanism that 'reads the pattern of electromagnetic waves and detects the presence or absence of a virus' has been developed. This external device utilizes the inexpensively available Raspberry Pi.

The technology itself for detecting electromagnetic waves unique to malware was already being developed in a project led by the US Defense Advanced Research Projects Agency (DARPA) as of 2021.

This announcement was made by the French research institute ' Institute of Computer Science and Random Systems (Irisa) '. Unlike the above research, the point is that it uses a Raspberry Pi, an H-Field probe (magnetic field probe), and an oscilloscope to detect viruses.

When a program is executed, electromagnetic waves are generated from the hardware, and the patterns of the electromagnetic waves differ depending on the code executed by the program. Using this property, the research team first picked up the electromagnetic wave pattern of the virus running on various devices with an H-Field probe and visualized it with an oscilloscope. After that, the research team who confirmed that there are various patterns of electromagnetic waves due to the virus used this information to program the Raspberry Pi so that it could identify the electromagnetic wave pattern of the virus.

And when we actually read the electromagnetic waves with an H-Field probe placed near an IoT device or smartphone and tested whether the presence of the virus could be detected and identified on the Raspberry Pi side, 99.82% of the malware was detected. It was possible to identify it as a harmless virus.

Many of the existing malware detection mechanisms are 'installing software on the device'. On the other hand, it is worth noting that the technology developed this time does not require software installation and is detected by an external system. In addition, virus creators use various technologies so that the users of the device do not realize it, but the 'external system' and 'mechanism for detecting electromagnetic waves' are also excellent in that they are not easily affected by such technologies. I am. At the time of writing the article, it seems that it is not considered to sell such a device to general consumers, but it is said that it may be used in cases that require a large system or server. ..
