Israeli hackers stole data from the computer simply recording the vibrations of his cooler

Researchers from the University of Ben-Gurion in Israel is known for its expertise and remarkable talent to invent and successfully use exotic ways of hacking digital systems and gadgets. Their favorite niche – extraction of data from a PC that is not physically connected to any of networks. Recently they have introduced another method, which is based on the recording and analysis of vibrations from coolers inside the system unit.

Israeli hackers have long ago brought a number of patterns between executing by the computer the specific tasks and physical effects that accompany this process. In this case the subject of interest are micro-vibrations of the main components of the system unit – the CPU, hard disk, coolers, graphics cards, etc. to make signals more informative, hackers are implemented on a PC a simple Trojan, which controls the speed of rotation of the main cooler when its vibrations are the most apparent.

To read the vibrations perfectly fit in the normal serial Galaxy S10, which has a very sensitive accelerometer – it resolution up 0,0023956299 m/S2. In Android, the iOS, data processing from the accelerometer is in the background and is not visible from the outside. Sufficient to put the smartphone at a distance of 1.5 m from the PC case not in a very noisy environment – and you can read data from it.

The technology is called AiR-ViBeR, it has proven its reliability, but applications in the cyber environment, is not likely to get. First, the read speed is unsatisfactorily low, and secondly, a similar development is underway to identify vulnerabilities and improve the protection, not theft of data. And the secret services, who was interested in technology, is unlikely to want to share it with someone else.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
