How Raspberry Pi can detect virus without any software

A team of researchers has built a non-software virus detection system using a Raspberry Pi, an H-field probe and an oscilloscope. This kit makes it possible to detect electromagnetic wave signals specific to certain types of viruses.

Computer errors are as old as the computer itself. The history of the first bug in history dates back to… 1947. Since then, malfunctions affecting our devices have become common, and some of them have had serious consequences.

berries with me Since its inception, both the Swiss Army Knife and . have been 4×4 Information technology with its primitive aspect, improved architecture, maximum strength and flexibility. Although it is possible to manufacture many devices of all typesApplications. Encapsulated in a small cube, it was used to test methods encryption in a l’ISS. It has also been used for pirates a job NASA.

The Raspberry Pi has once again emerged in the field of cyber security. In France, the Irisa laboratory (Institute of Computer Science and Random Systems) a advanced Virus detection system using nanocomputer. Combined with the H-field probe, i.e. a sensor From electromagnetic fieldAnd the oscillations. How this strange assembly is able to detect the presence of computer viruses? By focusing on the detection of signaturesElectromagnetic waves Several types of viruses, especially those that attack Connected accessories, whose firmware is not known to be vulnerable. This is what the team of scientists made clear last December when presenting the results of their tests at the conference. ACM machines.

waves to detect viruses

Scientists began to note that a software Active generates its own electromagnetic waves. It is, in a way, a unique signature. A virus is a computer program like any other virus, and it also has a signature electromagnetic Unique. A theory confirmed by an oscilloscope from several viruses already known and implemented on different devices. The researchers collected these signatures and used them to program the Raspberry Pi, with the device now acting using its sensors as a virus detector. To check if a virus is active in a file smart phone, a computer or even a connected accessory, all you have to do is place an H-field probe near the device so it can collect the electromagnetic waves that it propagates.

Then the Raspberry Pi indicates if it found those in its virus database, and if so, which one. Tests revealed that the system was able to detect 99.82% of Malware So called generic. In the end, no antivirus is needed and this detector allows you to detect a mask virus The most stealthy even if the authors take care to conceal their presence so they can squeeze the networks of the best security systems out. Although this invention sounds great, it should not become a popular antivirus solution. Scientists believe at best that this detector can be useful for professional systems and servers.
