A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to.

In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0–22 kHz, carrying encoded signals within those acoustic waves that can be captured by nearby devices such as smartphones.

The researchers’ tests showed that data exfiltration is possible at a maximum distance of 2 meters (6.5 ft), achieving a data rate of 20 bits per second (bps).

Researchers have developed a new smartphone-based digital holographic microscope that enables precision 3D measurements. The highly portable and inexpensive microscope could help bring 3D measurement capabilities to a broader range of applications, including educational uses and point-of-care diagnostics in resource-limited settings.

A hot potato: For almost as long as we’ve had smartphones, there has been the belief that they surreptitiously listen to our spoken conversations to serve us targeted ads; most people have experienced seeing an ad on Facebook for something they were recently talking about. It’s always been claimed that this type of privacy invasion doesn’t happen. However, a marketing agency, whose clients included Facebook and Google, has admitted to using an “Active Listening” feature that eavesdrops on conversations via phone mics to gather data.

A pitch deck from Cox Media Group (CMG), seen by 404 Media, states that the marketing firm uses its AI-powered Active Listening software to capture real-time data by listening to phone users’ conversations. The slide adds that advertising clients can pair the gathered voice data with behavioral data to target in-market consumers.

Android users have been warned that a dangerous new hack attack uses optical character recognition to grab passphrases from your smartphone.

A newly developed transistor device has shown exceptional levels of resilience in tests, performing so well, in fact, that it promises to transform the electronics and gadgets we make use of each day.

These tiny toggles are essential in just about every modern day electronic device, involved in storing data and processing information in a binary ‘on’ or ‘off’ state, switching back and forth multiple times a second.

Thanks to its remarkable combination of speed, size, and resilience to wear, this latest design potentially represents a huge upgrade for consumer devices like phones and laptops, as well as the data centers that store all of our information in the cloud.

Why do we take so many selfies? Because we are afraid of dying, say psychologists.

Many of us have phones filled with selfies documenting everything from holidays to duvet days.

But what’s behind the modern fascination with taking photos of ourselves?

Researchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. The research is published in the journal ACS Applied Materials & Interfaces.

A capacitor is a device used as part of a circuit that can store and release energy, just like a battery. What makes a capacitor different from a battery is that it takes much less time to charge. For example, your cellphone battery will power your phone instantly, but charging that battery back up to 100% when it dies is far from instantaneous.

While this makes capacitors sound like the superior choice, they have some big drawbacks that need to be overcome. First, their capacity is much smaller than batteries, so they cannot store large amounts of energy at once. Second, they can be quite expensive.

For the Artemis 3 mission, we will be able to reach astronauts up to 2 kilometers away from the lander.
