The attackers used a combination of Android, Chrome, and Windows vulnerabilities, including both zero-days and n-days exploits.
Chipmakers often place orders with contract manufacturers instead of fabricating chips in-house. It takes time to manufacture semiconductors while reconfiguring lines to accommodate varying specifications, making it difficult to turn out different chips at the same time.
TOKYO — The auto industry is facing a severe lack of semiconductors amid rising use of the chips in other products, like smartphones and communication base stations.
This has forced Germany’s Volkswagen as well as Japanese makers like Honda and Nissan to reduce production.

All the clean technologies that we need to combat climate change – whether that’s wind turbines, solar panels or batteries, they’re all really, really mineral intensive.
Cornwall, 1864. A hot spring is discovered nearly 450m (1485ft) below ground in the Wheal Clifford, a copper mine just outside the mining town of Redruth. Glass bottles are immersed to their necks in its bubbling waters, carefully sealed and sent off for testing. The result is the discovery of so great a quantity of lithium – eight or 10 times as much per gallon as had been found in any hot spring previously analysed – that scientists suspect “it may prove of great commercial value”.
But 19th-Century England had little need for the element, and this 50C (122F) lithium-rich water continued steaming away in the dark for more than 150 years.
Wi-Fi 6E devices are now being certified by the Wi-Fi Alliance. Smartphones, PCs, and laptops are expected in the first quarter of 2021, while TVs and VR devices should follow in the second quarter of 2021.
Despite the inherent challenges that voice-interaction may create, researchers at the Penn State College of Information Sciences and Technology recently found that deaf and hard-of-hearing users regularly use smart assistants like Amazon’s Alexa and Apple’s Siri in homes, workplaces and mobile devices.
The work highlights a clear need for more inclusive design, and presents an opportunity for deaf and hard-of-hearing users to have a more active role in the research and development of new systems, according to Johnna Blair, an IST doctoral student and member of the research team.
“As smart assistants become more common, are preloaded on every smartphone, and continue to provide benefits to the user beyond just the ease of voice activation, it’s important to understand how deaf and hard-of-hearing users have made smart assistants work for them and the realistic challenges they continue to face,” said Blair.
On the first day of a popular psychology course in the 1970s at City College of New York, students were told the story of how a remote South American tribe that was never exposed to technology or even electricity reacted when they saw a cowboy program on TV for the first time. Panic-stricken viewers dodged out of the way as galloping horses disappeared at the edge of the screen, while others searched high and low to find the missing animals. These were old, bulky televisions with scrappy black-and-white displays. But to the tribe members, the images were chillingly real.
One wonders how those folks—not to mention modern-day tech geeks as well as the general public—would react to a portable projector that fits in the palm of your hand and is capable of displaying stunningly realistic 3D color holographic images. Chances are they’d be pretty impressed.
Looking Glass Factory, a Brooklyn-based tech firm, is set to offer an 8 holographic display called Portrait that will convert users’ favorite personal photos into lifelike holograms. No special equipment or skills are required. Users simply take regular 2-D photos with any device, ranging from sophisticated DSLR setups to low-end cellphones—even old family Polaroids should work—and send them to Looking Glass Factory’s cloud-based service.
A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries.
Usually, energy storage is associated with batteries and accumulators that provide energy for electronic devices. However, in laptops, cameras, cellphones or vehicles, so-called supercapacitors are increasingly installed these days.
Unlike batteries they can quickly store large amounts of energy and put it out just as fast. If, for instance, a train brakes when entering the station, supercapacitors are storing the energy and provide it again when the train needs a lot of energy very quickly while starting up.
The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and translucent parts at an angle over another material of similar contrast.
A team of researchers from Tokyo University of Agriculture and Technology, TUAT, in Japan have demonstrated that moiré metalenses—tiny, patterned lenses composed of artificial ‘meta’ atoms—can tune focal length along a wider range than previously seen. They published their results on November 23 in Optics Express.
“Metalenses have attracted a lot of interest because they are so thin and lightweight, and could be used in ultra-compact imaging systems, like future smart phones, virtual reality goggles, drones or microbots,” said paper author Kentaro Iwami, associate professor in the TUAT Department of Mechanical Systems Engineering.
Third party data collection — whatever the motivation — has the potential to blur the lines between data privacy and complete identification.

In March 2020, it was revealed that the Zoom iOS app was sending user data to Facebook unbeknownst to the user. The transaction conspired in a manner where Zoom had implemented the ‘login from Facebook’ button on its iOS app, subsequently involving the Facebook Software Development Kit (SDK) in its iOS platform. The implementation of this feature allowed Facebook to access and extract users’ data from Zoom’s platform. Zoom apologised for this incident, claiming that it did not know of such implications while developing the app, further stating that it had rectified its mistake and fixed the app to remove the Facebook SDK.
