Malware exploited critical Realtek SDK bug in millions of attacks

Posted by in categories: cybercrime/malcode, electronics

Hackers have leveraged a critical remote code execution vulnerability in Realtek Jungle SDK 134 million attacks trying to infect smart devices in the second half of 2022.

Exploited by multiple threat actors, the vulnerability is tracked as CVE-2021–35394 and comes with a severity score of 9.8 out of 10.

Between August and October last year, sensors from Palo Alto Networks observed significant exploitation activity for this security issue, accounting for more than 40% of the total number of incidents.

Wi-Fi Can Now ‘See’ People, Tech Could One Day Replace Cameras

Posted by in categories: electronics, internet

Scientists have developed a way to detect 3D shapes and the movements of human bodies in a room using a Wi-Fi router.

The researchers at Carnegie Mellon University in the U.S. hope that the technology may eventually replace normal cameras.

According to a recent paper published on arXiv, the team of scientists managed to make out images of people in a room through the Wi-Fi signals emitted from a normal router.

Chips using integrated photonic circuits could help close the ‘terahertz gap’

Posted by in categories: computing, electronics

Researchers have developed an extremely thin chip with an integrated photonic circuit that could be used to exploit the so-called terahertz gap – lying between 0.3-30THz in the electromagnetic spectrum – for spectroscopy and imaging.

This gap is currently something of a technological dead zone, describing frequencies that are too fast for today’s electronics and telecommunications devices, but too slow for optics and imaging applications.

However, the scientists’ new chip now enables them to produce terahertz waves with tailored frequency, wavelength, amplitude and phase. Such precise control could enable terahertz radiation to be harnessed for next-generation applications in both the electronic and optical realms.

Dutch Startup 3D Prints Bridge With 10,000 Pounds of Stainless Steel

Posted by in categories: electronics, engineering

If you walk along the Oudezijds Achterburgwal canal in Amsterdam, you will notice an elegant and aesthetically pleasing steel bridge for pedestrians. If not for the media attention it got, you would even consider it a regular feature of the city’s architecture. But this bridge loaded with sensors, is actually the world’s first 3D-printed steel bridge, according to an Imperial College London press release.

“A 3D-printed metal structure large and strong enough to handle pedestrian traffic has never been constructed before,” said Imperial co-contributor Prof. Leroy Gardner of the Department of Civil and Environmental Engineering, in a press release. “We have tested and simulated the structure and its components throughout the printing process and upon its completion, and it’s fantastic to see it finally open to the public.”

Optical coating approach prevents fogging and unwanted reflections

Posted by in categories: electronics, nanotechnology

Researchers have developed an optical coating system that combines antifogging and antireflective properties. The new technology could help boost the performance of lidar systems and cameras.

“Walking into a warm room from the cold outside can cause glasses to fog up, blinding the user,” said research team leader Anne Gärtner from Fraunhofer Institute for Applied Optics and Precision Engineering and Friedrich Schiller University Jena, both in Jena, Germany. “The same can happen to sensors such as the lidar systems used in autonomous cars. It is important that surfaces remain highly transparent, even if fogging occurs, so that functionality is maintained.”

In Applied Optics, Gärtner and colleagues describe how they combined a that prevents fogging with porous silicon dioxide nanostructures that reduce reflections. Although the coatings described in the paper were designed specifically for lidar systems, the technology can be tailored for many different applications.

Flying hovercraft glides over land and water at 70 mph

Posted by in category: electronics

Hammacher Schlemmer, a U.S. catalog company, has recently listed a flying hovercraft for purchase. The company claims that the craft can not only hover over land and water but that it can fly through the air at impressive speeds. A flying hovercraft may sound like something out of a comic book, but it’s a real product with some unique and noteworthy features.

About Hammacher Schlemmer

People may be surprised to hear that Hammacher Schlemmer, a company that sells decorations, sporting goods, furniture, and uncommon electronics, is offering a flying hovercraft. However, it’s important to note that the company doesn’t create or design its products. Instead, it offers a catalog of products that 3rd party manufacturers designed.

Flux Capacitors and the Origin of Inertia

Posted by in categories: electronics, energy

The explanation of inertia based on “Mach’s principle” is briefly revisited and an experiment whereby the gravitational origin of inertia can be tested is described. The test consists of detecting a small stationary force with a sensitive force sensor. The force is presumably induced when a periodic transient Mach effect mass fluctuation is driven in high voltage, high energy density capacitors that are subjected to 50 kHz, 1.3 kV amplitude voltage signal, and threaded by an alternating magnetic flux of the same frequency. An effect of the sort predicted is shown to be present in the device tested. It has the expected magnitude and depends on the relative phase of the Mach effect mass fluctuation and the alternating magnetic flux as expected. The observed effect also displays scaling behaviors that are unique to Mach effects.
