A team of engineers has developed a new type of camera that can detect radiation in terahertz (THz) wavelengths. This new imaging system can see through certain materials in high detail, which could make it useful for security scanners and other sensors.

Terahertz radiation is that which has wavelengths between microwaves and visible light, and these frequencies show promise in a new class of imaging systems. They can penetrate many materials and capture new levels of detail, and importantly the radiation is non-ionizing, meaning it’s safer than X-rays when used on humans.

The problem is that detectors that pick up THz wavelengths can be bulky, slow, expensive, difficult to run under practical conditions, or some combination of these. But in a new study, researchers at MIT, Samsung and the University of Minnesota have developed a system that can detect THz pulses quickly, precisely and at regular room temperature and pressure.

The company gives its customers full control over their data and claims to increase security, with a focus on compliance and auditing.

The invention could enhance the speed of electronic devices and improve security screening technology.

Chinese scientists have conceived of a new method for generating laser-like light that could significantly enhance the communication speed of everyday electronics, according to a report by the South China Morning Post.

The new device that makes this light possible is known as a free-electron laser, and it has been developed by scientists from the Shanghai Institute of Optics and Fine Mechanics under the Chinese Academy of Sciences.

A research team based out of the University of Waterloo has developed a drone-powered device that can use Wi-Fi networks to see through walls.

The device, nicknamed Wi-Peep, can fly near a building and then use the inhabitants’ Wi-Fi network to identify and locate all Wi-Fi-enabled devices inside in a matter of seconds.

The Wi-Peep exploits a loophole the researchers call polite Wi-Fi. Even if a network is password protected, smart devices will automatically respond to contact attempts from any device within range. The Wi-Peep sends several messages to a device as it flies and then measures the response time on each, enabling it to identify the device’s location to within a meter.

A set of four malicious applications currently available in Google Play, the official store for the Android system, are directing users sites that steal sensitive information or generate ‘pay-per-click’ revenue for the operators.

Some of these sites offer victims to download fake security tools or updates, to trick users into installing the malicious files manually.

At the time of publishing, the apps are still present on Google Play under a developer account called Mobile apps Group, and have a total install count of more than one million.

Scientists including an Oregon State University materials researcher have developed a better tool to measure light, contributing to a field known as optical spectrometry in a way that could improve everything from smartphone cameras to environmental monitoring.

The study, published today in Science, was led by Finland’s Aalto University and resulted in a powerful, ultra-tiny spectrometer that fits on a microchip and is operated using artificial intelligence.

The research involved a comparatively new class of super-thin materials known as two-dimensional semiconductors, and the upshot is a proof of concept for a spectrometer that could be readily incorporated into a variety of technologies—including quality inspection platforms, security sensors, biomedical analyzers and space telescopes.

Five malicious dropper Android apps with over 130,000 cumulative installations have been discovered on the Google Play Store distributing banking trojans like SharkBot and Vultur, which are capable of stealing financial data and performing on-device fraud.

“These droppers continue the unstopping evolution of malicious apps sneaking to the official store,” Dutch mobile security firm ThreatFabric told The Hacker News in a statement.

“This evolution includes following newly introduced policies and masquerading as file managers and overcoming limitations by side-loading the malicious payload through the web browser.”

I guess it’s time for Twitter execs to go home, and for me to start using Twitter again. They killed my chamber of commerce account, then when I opened a personal account, they kept asking for my phone number every time I logged in. If I give you my number once and you send me an sms, I’m not giving it to you again, as that’s not safe.

It ends months of bad blood between the two parties regarding the takeover, with Elon Musk complaining about fake accounts on the platform and claims by a whistleblower that Twitter misled regulators about security risks.
