In Israel, they figured out how to steal data from a computer using a speaker and a smartphone

In Israel, they showed a new technique for stealing data from an isolated PC. For this, an ultrasonic channel and a smartphone gyroscope are used. The new method is called GAIROSCOPE and was developed by Israeli researcher Mordechai Guri.

The technique uses a program that causes an isolated computer to transmit information using a microelectromechanical system (MEMS). Such a system can emit ultrasound, which is then captured using a smartphone’s gyroscope, and another program can decode the data and translate it into binary code. A computer speaker is used as an example of MEMS.

At the first stage, it is necessary to install a program for generating ultrasound on the victim’s computer. This can be done in different ways – from a banal flash drive to a hacker attack or compromise of software supply chains. You can even embed such a program into a web page using JavaScript. You also need to infect the smartphone of company employees. This can be done using a hacked website or mobile app.

After that, the speaker can transmit data in the range of ultrasound that a person cannot hear. The infected smartphone is nearby and perceives these signals using a gyroscope, after which it is only necessary to send them from the smartphone via Wi-Fi.

Experimental results show that a similar method can be used to transmit data at a speed of 1-8 bps at distances of 0-600 cm. That is, it is only suitable for stealing keys. Passwords and other similar information.

Guri notes that it is possible to defend against the attack. For this you need:

  • remove speakers and sound drivers from computers;
  • track ultrasonic signals using sensors;
  • oblige employees to keep smartphones at least 800 cm away from computers;
  • drown out the signal with external noise.

Previously, the same researcher developed the SATAn attack method, which uses a SATA cable as an antenna for data transmission.

Black and White LCD, Wi-Fi, and $249 Mechanical Keyboard Pre-Order: Unique Writing Computer Introduced

Black and White LCD Wi Fi and 249 Mechanical Keyboard Pre Order

Modern PCs and smartphones have long become universal devices that allow a lot. But AstroHous seems to think that dedicated systems are better. The developers have introduced a portable device called Freewrite Alpha, which is designed for writers. This is a kind of modern “reissue” of electric typewriters and word processors.

The novelty is equipped with a monochrome LCD display measuring 6.5 by 1 inch, which is enough to display from 2 to 6 lines of text at a time, depending on the font size. Alpha also has a full-size mechanical keyboard on Kailh Choc V2 switches, a USB-C port for charging a 4200 mAh battery, an 802.11b/g/n Wi-Fi adapter, and some modern features, including basic text editing, cloud sync and autosave.

Note that Freewrite also has more advanced models with E ink screens, but the price is higher. The Alpha is available for pre-order for $249 and will retail for $349 in Summer 2023.

The main advantage of the device can be considered its instantaneous activation, which is sometimes important for writers. There’s also support for Freewrit mail and third-party services, including Dropbox, Google Drive, and Evernote.

The design of the Freewrite Alpha is inspired by classic devices from the 1980s and 1990s such as the AlphaSmart, Cambridge Z88, and TRS-80 Model 100. AstroHous plans to only sell English layout versions at this time, but other language options may be added if there is demand. .

Global climate change will provoke regular powerful downpours. An article about this is published in Geophysical Research Letters.

Computer simulations have shown that global warming will lead to regular super downpours

This conclusion was made by specialists from the University of Copenhagen and the Danish Meteorological Institute when studying a super shower that passed over Copenhagen in July 2011. The authors of the work decided to recreate it in a computer simulation to find out what caused it. The simulation was run 13 times, once for each level of global temperature, namely: -1 degrees Celsius relative to the norm (pre-industrial era), 0 (norm in 2011), and +1, +2 and +3 degrees Celsius . The distance between the data points in the model, known as the grid size, was about 2.5 kilometers (this can be roughly considered model pixels). In comparison, global climate model grid points are typically at least 50 kilometers apart, so the new simulation can be considered extremely accurate.

It turned out that the higher the temperature was, the more abundant the downpour became and the more powerful the flood it caused. In particular, if the climate had not warmed by one degree over the 20th century, the chance of the formation of a super shower in 2011 would have been half as much. The authors of the paper believe that this fact should be taken into account when planning climate policy.
