Raspberry Pi-based device uses electromagnetic waves to detect malware
Antivirus software often relies on a combination of machine learning algorithms and frequently updated malware definitions to protect our computers from external threats. However, no antivirus software is perfect, and they occasionally miss updated or heavily disguised threats. That’s why researchers at the Institute for Computer Science and Stochastic Systems are trying to explore new ways to detect malicious programs that don’t rely on software solutions at all.
Instead, the four-member team is using electromagnetic pulses to detect harmful software. Even if the target is obfuscated. Their method is unorthodox, to say the least, but also fairly accurate based on their initial tests.
The technology developed by the team uses a Raspberry Pi to connect infected or potentially infected devices. The Pi interfaces with an H-field probe and an oscilloscope: the former detects the magnetic waves emitted by the device, and the latter visualizes them for malware analysts to review.
According to the researchers, different kinds of malware emit specific electromagnetic waves. Since everything seems to emit such waves these days, it’s not enough to just set up the system and analyze the output of the oscilloscope. Pi-based malware detectors must be trained on a variety of threats to improve their detection accuracy and eradicate false positives.
In the researchers’ experiments, the Pi was able to predict three “generic malware types” and one “benign” category (harmless malware that’s probably more annoying than anything) with about 99.82 percent accuracy. The team noted that it doesn’t matter what obfuscation techniques the software in question might use on the software side, because their devices don’t rely on software. It works at a higher level.

Last month, SpiceJet also commenced UDAN flights linking Shivamogga in Karnataka with Chennai and Hyderabad, and introduced double daily flights between Chennai and Kochi, enhancing connectivity across key regional and metropolitan cities.
“We are excited to announce the launch of new flights from Jaipur to Varanasi, Amritsar, and Ahmedabad, as well as from Ahmedabad to Pune, providing our passengers with greater flexibility and convenience,” SpiceJet Chief Business Officer Debojo Maharshi said.
“These new flights reflect our commitment to supporting passenger demand across tier-II cities and beyond. With our expanded winter schedule, including international and UDAN routes, we aim to provide our customers with greater convenience, affordability, and seamless travel experiences,” Maharshi added.
SpiceJet will deploy its 78-seater Q400 aircraft in these sectors. Bookings for the new flights are now open and tickets are available at the website of the airline, SpiceJet’s mobile app and through online travel portals and travel agents.
On Monday, the airline received a significant boost, with Acuite Ratings & Research Limited upgrading its long-term rating by four notches to ‘B ‘ and its short-term rating to A4. The rating agency has also assigned a ‘Stable’ outlook to the airline.
