Android app from China executed 0-day exploit on millions of devices

Posted by in categories: computing, mobile phones, neuroscience, security

Can you imagine if we had computer/brain interfaces what would happen? We’ll need brain firewalls and antivirus.


Android apps digitally signed by China’s third-biggest e-commerce company exploited a zero-day vulnerability that allowed them to surreptitiously take control of millions of end-user devices to steal personal data and install malicious apps, researchers from security firm Lookout have confirmed.

The malicious versions of the Pinduoduo app were available in third-party markets, which users in China and elsewhere rely on because the official Google Play market is off-limits or not easy to access. No malicious versions were found in Play or Apple’s App Store. Last Monday, TechCrunch reported that Pinduoduo was pulled from Play after Google discovered a malicious version of the app available elsewhere. TechCrunch reported the malicious apps available in third-party markets exploited several zero-days, vulnerabilities that are known or exploited before a vendor has a patch available.

Surprise Computer Science Proof Stuns Mathematicians

Posted by in categories: computing, mathematics, science

For decades, mathematicians have been inching forward on a problem about which sets contain evenly spaced patterns of three numbers. Last month, two computer scientists blew past all of those results.

Was Gordon E. Moore and Moore’s Law Aspirational or Inspirational?

Posted by in category: computing

Gordon E. Moore who died last week had a vision that silicon chips and shrinking transistors would revolutionize computing. Moore’s Law inspired the computer revolution.


Moore died at the age of 94 but Moore’s Law drove the computing revolution from the mid-1960s. Transistor miniaturization was the key.

Grimes said she got a brain gadget for her birthday from a company competing with Elon Musk’s Neuralink

Neurosity’s headset uses electroencephalogram technology, or EEG, to measure brain activity by placing small metal electrodes on a person’s scalp. If the electrodes detect decreased electrical activity in the brain, the Crown plays music and sounds, or pulses vibrations, hoping those actions will help the user focus.

But some developers, it seems, have taken Neurosity’s tech a step further, turning the Crown into a more traditional brain computer interface that can allow users to control a computer using only their mind.

One owner of the gadget claimed they’ve used it to drive a Tesla, moving the electric car short distances by doing some mental math, which signals to the device that the person wearing it is exerting a lot of cognitive effort.

Carbon Nanotubes for Digital Logic

Posted by in categories: computing, nanotechnology

Speaker: George Tulevski, materials science engineer at IBM Research.

The exceptional electronic properties of carbon nanotubes, coupled with their small size, makes them ideal materials for future nanoelectronic devices. The integration of these materials into advanced microprocessors requires a radical shift in fabrication from conventional top-down process to bottom-up assembly where advances in sorting and directed assembly are needed. This presentation will briefly describe the challenges to future transistor scaling, highlight the advantages of employing carbon nanotubes for digital logic and describe the recent progress in this area.

The best of both worlds: A new algorithm fuses quantum and classical information for high-quality imaging

Posted by in categories: computing, information science, quantum physics

Researchers from Colorado State University and the Colorado School of Mines have thought up a new computational imaging strategy that exploits the best of both the quantum and classical worlds. They developed an efficient and robust algorithm that fuses quantum and classical information for high-quality imaging. The results of their research were published Dec. 21 in Intelligent Computing.

Recently, the quantum properties of light have been exploited to enable super resolution microscopy. While quantum information brings new possibilities, it has its own set of limitations.

The researchers’ approach is based on classical and quantum correlation functions obtained from photon counts, which are collected from quantum emitters illuminated by spatiotemporally structured illumination. Photon counts are processed and converted into signals of increasing order, which contain increasing spatial frequency information. The higher spatial resolution information, however, suffers from a reduced signal-to-noise ratio at increasingly larger correlation orders.

The end of text-based passwords? ‘Transparent image moving’ provides a new solution

Posted by in categories: computing, mobile phones, security

It’s past time the world moves away from text-based passwords and verifications for mobile phones and starts embracing more secure image-based solutions, say computer scientists from the University of Surrey.

In a new study, Surrey scientists demonstrate an image-based authentication system called TIM (Transparent Image Moving) for mobile phones to help reduce the risk of shoulder surfing attacks. TIM requires users to select and move predefined images to a designated position for passing authentication checks, similar to those required for .

The proof-of-concept study found that 85% of TIM users believed it could help them to prevent password guessing and shoulder surfing attacks. The study also found that 71% of participants think TIM is a more usable image-based solution than others on the market. The research has been published in the Journal of Information Security and Applications.
