26 Billion User Records Compromised

A leak of around 26 billion user records has been labeled "the mother of all breaches." It's a major reminder of the downsides of reusing the same passwords on multiple sites. The collection of records is not a single stolen database. Instead, it ... appears to be a massive compilation of databases that have either been leaked before or sold on the black market. The database was spotted online by security researchers, likely a sign that whoever compiled it screwed up somewhere by mistakenly making it accessible. The researchers noted the database was extremely well indexed and organized. The ... (view more)

Study: No Evidence Internet Harms Mental Health

Researchers say they were unable to find a clear link between Internet use and harm to mental health. However, the results looked at national populations as a whole, rather than individual behavior. The researchers, from Oxford University's Oxford ... Internet Institute, said they were limited by a lack of data and cooperation from major tech companies. The broad research paper, "Global Well-Being and Mental Health in the Internet Age", looked at studies of psychological wellbeing of around 2.4 million people across 18 countries. The researchers looked at changes in reported wellbeing between ... (view more)

Security Glitch Undermines Encryption Keys

Around one in a million computer encryption keys are faulty and could be compromised according to researchers. While it sounds like an obscure issue, it could be exploited by security agencies at both friendly and hostile governments. The problem is ... with the RSA encryption that's widely used for online security. It works by users having two security keys (lengthy codes), one public and one private. The public key is used for encrypting data, while the private key is needed to decrypt it. The system also allows users to "sign" encrypted messages so that recipients know the supposed sender is ... (view more)

Report: 40 Percent of Internet Users 'Addicted'

More than four in ten people are addicted to Internet use, according to a university study. The researchers put respondents into five categories on what they are calling an "Internet addition spectrum." Researchers at the University of Surrey in the ... United Kingdom asked 796 participants a range of questions about the way they use the Internet, including their emotions and motivations. They then looked for similarities between respondents to come up with the categories. (Source: tandfonline.com ) Growing Unease The first category, Casual Users, covered 14.86 percent of respondents. They mainly ... (view more)

Keyboard Sounds May Reveal Secrets

Researchers say they can accurately figure out what somebody is typing from the sound of their keyboard. The "technique" has some significant practical flaws but is a useful reminder of good password practice. The researchers looked into a theory ... that seems to get tested every few years: that different keys make different sounds. That's partly because they are differing distances from the device recording the audio and partly because the gaps between pressing different letters may vary depending on the typing style. The main difference with this latest test was using deep learning, which aims ... (view more)

Smartwatches Could Predict Parkinson's Disease

Researchers say smartwatches could predict people getting Parkinson's disease up to seven years before they developed symptoms. The next steps could be as much an ethical challenge as a technical one. The finding came from researchers who looked at ... data from the UK's Biobank project. That's a database that tracks anonymized health data from half a million volunteers. The idea is that the sheer amount of data makes it easier to spot patterns and connections between different health factors and conditions. As part of the project, just over 100,000 people agreed to wear a smart watch for a seven ... (view more)

Fitness Tracker 'Heatmap' Dubbed Privacy Risk

Researchers say a feature in a jogging and running app called Strava makes it possible to track down a user's home address. However, they make a pretty weak argument about how plausible and successful an attack would be. Strava lets users track ... their fitness activities, including running routes. Since 2018, the app has included a "heatmap" feature that shows areas where a lot of users are active. The idea is to let people spot well-used running routes that may be useful for their needs. The feature has already been criticized after it revealed routes used by US military personnel on foreign ... (view more)

Human Brain Cells Could Power Computers

Human brain cells could power computers of the future, according to a new study. Researchers say they've already seen a bunch of brain cells in a petri dish learn to play the old video game Pong. The bizarre-sounding concept already has a name: ... organoid intelligence, or OI for short. It's already prompted questions about the ethics involved. While the concept sounds pretty disturbing, the reality wouldn't be quite as unsettling as it might seem. There's no suggestion we'll be sticking human skulls inside the desktop computer in our living room. Instead, the idea is that brain cells, generated ... (view more)

Thermal Images Could Reveal Passwords

Researchers say a thermal imaging camera could help crack passwords. It's not exactly a looming threat for the average user, though the study does reinforce the important of longer passwords. The research from the University of Glasgow appears to ... have been inspired by noticing that thermal-imaging cameras are becoming more affordable (less than $220 in some cases) and wondering how they could combine with machine learning. The researchers say they same idea may have struck would-be criminals, so it was worth trying to get one step ahead of them. (Source: zdnet.com ) The project followed a ... (view more)

Study: Smart Assistants May Hamper Development

Two researchers say voice controlled "assistant" devices could harm children's development. The claims are more of a warning than proven results at this stage. The claims come from Ananya Arora and Anmol Arora, both of the School of Clinical ... Medicine at the University of Cambridge. They were writing in the publication Archives of Diseases in Childhood. (Source: bmj.com ) The pair say they have three main fears about the uses of devices such as the Amazon Echo and Google Home, along with Apple's Siri. In all three cases, the researchers say it appears some parents may have mistaken ... (view more)
