Symbiote: A Stealthy Linux Malware Targeting Latin American Financial Sector

Posted by in categories: cybercrime/malcode, finance, mobile phones

Cybersecurity researchers have taken the wraps off what they call a “nearly-impossible-to-detect” Linux malware that could be weaponized to backdoor infected systems.

Dubbed Symbiote by threat intelligence firms BlackBerry and Intezer, the stealthy malware is so named for its ability to conceal itself within running processes and network traffic and drain a victim’s resources like a parasite.

The operators behind Symbiote are believed to have commenced development on the malware in November 2021, with the threat actor predominantly using it to target the financial sector in Latin America, including banks like Banco do Brasil and Caixa, based on the domain names used.

How Apple’s M2 chip builds on the M1 with small but meaningful upgrades

Posted by in categories: computing, mobile phones

How Apple’s M2 chip builds on the M1 to take on Intel and AMD.


The M1 is a great chip. Essentially an “X” variant of the A14 chip, it takes the iPhone and iPad processor and doubles the high-performance CPU cores, GPU cores, and memory bandwidth. The M1 chip is so good it’s equally amazing for tablets and thin-and-light laptops as it is for desktops, easily outperforming any competing chip with similar power draw and offering similar performance to processors that use at least twice as much energy.

Now a year and a half later, and after delivering three more powerful variants of the M1 (M1 Pro, M1 Max, and M1 Ultra), it’s time for the next generation. Announced at WWDC and appearing first in the new MacBook Air and 13-inch MacBook Pro, the M2 is essentially the system-on-chip we predicted it would be: what the M1 is to the A14, the M2 is to the A15. It’s made of 20 billion transistors, 25 percent more than M1, and while it’s still built using a 5nm manufacturing process, it’s a new enhanced “second-generation” 5nm process.

All phones to use the same charger

Posted by in category: mobile phones

European Union policymakers have brought in new laws to introduce a universal phone charger.

Now it’s almost a reality, but while there’s widespread support from consumers and politicians, one company in particular isn’t happy.

A chip that can classify nearly 2 billion images per second

Posted by in categories: biotech/medical, mobile phones, robotics/AI

Artificial intelligence (AI) plays an important role in many systems, from predictive text to medical diagnoses. Inspired by the human brain, many AI systems are implemented based on artificial neural networks, where electrical equivalents of biological neurons are interconnected, trained with a set of known data, such as images, and then used to recognize or classify new data points.

In traditional neural networks used for , the image of the target object is first formed on an , such as the in a smart phone. Then, the image sensor converts light into , and ultimately into the , which can then be processed, analyzed, stored and classified using computer chips. Speeding up these abilities is key to improving any number of applications, such as face recognition, automatically detecting text in photos, or helping self-driving cars recognize obstacles.

While current, consumer-grade image classification technology on a digital chip can perform billions of computations per second, making it fast enough for most applications, more sophisticated image classification such as identifying moving objects, 3D object identification, or classification of microscopic cells in the body, are pushing the computational limits of even the most powerful technology. The current speed limit of these technologies is set by the clock-based schedule of computation steps in a computer processor, where computations occur one after another on a linear schedule.

Breakthrough leads to photonic sensing at the ultimate quantum limit

Posted by in categories: computing, mobile phones, quantum physics

Quantum sensing is poised to revolutionize today’s sensors, significantly boosting the performance they can achieve. More precise, faster, and reliable measurements of physical quantities can have a transformative effect on every area of science and technology, including our daily lives. However, most of these schemes are based on special entangled or squeezed states of light or matter that are difficult to detect. It is a significantly challenging task to harness the full power of quantum-limited sensors and deploy them in real-world scenarios.

A team of physicists at the Universities of Bristol, Bath, and Warwick have found a way to operate mass manufacturable photonic sensors at the quantum limit. They have shown that it is possible to perform high-precision measurements of critical physical properties without the need for sophisticated quantum states of light and detection schemes.

Using ring resonators is a key to this breakthrough discovery. The ring resonators are tiny racetrack structures that guide light in a loop and maximize its interaction with the sample under study. Importantly, ring resonators can be mass-produced in the same way chips in computers and cell phones are.

SideWinder hackers plant fake Android VPN app in Google Play Store

Posted by in categories: cybercrime/malcode, mobile phones

Phishing campaigns attributed to an advanced threat actor called SideWinder involved a fake VPN app for Android devices published on Google Play Store along with a custom tool that filters victims for better targeting.

SideWinder is an APT group that’s been active since at least 2012, believed to be an actor of Indian origin with a relatively high level of sophistication.

Security researchers at Kaspersky attributed close to 1,000 attacks to this group in the past two years. Among its primary targets are organizations in Pakistan, China, Nepal, and Afghanistan.

Smart films facilitate human-machine interaction

Posted by in categories: cyborgs, entertainment, mobile phones

Imagine this: A smooth touchscreen display placed on top of a thin silicone polymer film suddenly generates the feeling of a tiny raised button under the user’s finger. Or how about the idea of wearing that same polymer film like a second skin? If used to line an industrial glove, the film can provide valuable feedback by gesture recognition and by sending tactile signals, such as pulses or vibrations, to the wearer. The research team led by Professor Stefan Seelecke of Saarland University will be at this year’s Hannover Messe, the industrial trade fair running from 30 May to 2 June, where the team will be demonstrating how smart tactile surfaces are now being used as novel human-machine interfaces.

Seelecke’s research team at Saarland University are using thin silicone films to give surfaces some very novel capabilities. The technology, which is able to create the sensation of a tactile “button” or “slider” on flat glass display screens, is literally bringing a new dimension to touchscreen interactions. The is able to change shape on demand to create the feeling of a raised button or a key on the surface of the display that the user can then use, for example, to navigate around a page or to enter data.

“Using this technology, we can make the user interfaces of smart phones, information screens or household devices more user friendly,” said Seelecke, who heads the Intelligent Material Systems Lab at Saarland University. If a user feels a pulse or vibration under their fingertips, they can then respond by tapping the screen. And because the user also experiences the slight resistance that we feel when we press a ‘real’ button or switch, they know that their response has been successful. For the blind and partially sighted, this sort of physical feedback is not a gimmick, but hugely valuable in their day to day lives.

“Fly ash” contains rare earth elements needed for electronics

Posted by in categories: mobile phones, satellites, sustainability

The United States’ reliance on China for rare earth elements could soon come to an end, thanks to a new process that pulls the valuable metals from the ash left over when we burn coal.

Why it matters: The 17 rare earth elements aren’t actually rare — they’re all more common than gold, and one is more abundant than copper. But getting our hands on them is difficult because they’re widely dispersed in Earth’s crust and hard to extract through mining.
