A team of researchers designed a non-software virus detection system using a Raspberry Pi, an H-field probe, and an oscilloscope. This set makes it possible to detect the signatures of electromagnetic waves specific to certain types of viruses.
It is once again in the field of cybersecurity that the Raspberry Pi has just stood out. In France, the Irisa lab (Institute of Computer Science and Random Systems) a a virus detection system using the nanocomputer. It was combined with an H-field probe, i.e. a from , and an oscilloscope. How is this strange assembly able to detect the presence of computer viruses? By focusing on the detection of signatures of several types of viruses, especially those that attack , whose firmwares are not known for their invulnerability. This is what the team of scientists explained in December when presenting the results of their tests at the conference. ACM Machinery.
Waves to detect viruses
Scientists started from the observation that aactive generates its own electromagnetic waves. It is, in a way, a unique signature. A virus being a computer program like any other, it also has a signature unique. A theory that has been confirmed by oscilloscope from several viruses already known and executed on various devices. The researchers collected these signatures and used them to program a Raspberry Pi. With its sensors, the device now serves as a virus detector. To check if a virus is active on a , a computer or even a connected accessory, all you have to do is place the H-field probe near the device so that it can collect the electromagnetic waves it diffuses.
The Raspberry Pi then indicates whether it has found those specific to its virus database, and if so, which one. Tests revealed that the system was able to detect 99.82% ofso-called generic. In the end, no need for antivirus software and this detector allows you to unmask the the most stealthy even if the authors have taken care to hide their presence so that they can squeeze through the meshes of the best security systems. While this invention sounds great, it shouldn’t really become a popular antivirus solution, however. Scientists believe at best that this detector could be useful for professional systems and servers.
