A new study from the University of Pennsylvania finds that preteens who own smartphones by age 12 have significantly higher odds of depression, obesity, and poor sleep compared to their peers. Axios reports: Kids who owned a smartphone at age 12 were found to have about 31% higher odds of depression, 40% higher odds of obesity and 62% higher odds of insufficient sleep than their peers who didn't have one. The researchers analyzed data from the National Institutes of Health-supported Adolescent Brain Cognitive Development Study assessments conducted between 2016 and 2022. The study included responses from 10,588 youths. Kids who had smartphones were more likely to be female, Black or Hispanic, and from lower-income households. The study has been published in the journal Pediatrics.

An anonymous reader quotes a report from 404 Media: Someone recently managed to get on a Microsoft Teams call with representatives from phone hacking company Cellebrite, and then leaked a screenshot of the company's capabilities against many Google Pixel phones, according to a forum post about the leak and 404 Media's review of the material. The leak follows others obtained and verified by 404 Media over the last 18 months. Those leaks impacted both Cellebrite and its competitor Grayshift, now owned by Magnet Forensics. Both companies constantly hunt for techniques to unlock phones law enforcement have physical access to. "You can Teams meeting with them. They tell everything. Still cannot extract esim on Pixel. Ask anything," a user called rogueFed wrote on the GrapheneOS forum on Wednesday, speaking about what they learned about Cellebrite capabilities. GrapheneOS is a security- and privacy-focused Android-based operating system. rogueFed then posted two screenshots of the Microsoft Teams call. The first was a Cellebrite Support Matrix, which lays out whether the company's tech can, or can't, unlock certain phones and under what conditions. The second screenshot was of a Cellebrite employee. According to another of rogueFed's posts, the meeting took place in October. The meeting appears to have been a sales call. The employee is a "pre sales expert," according to a profile available online. The Support Matrix is focused on modern Google Pixel devices, including the Pixel 9 series. The screenshot does not include details on the Pixel 10, which is Google's latest device. It discusses Cellebrite's capabilities regarding 'before first unlock', or BFU, when a piece of phone unlocking tech tries to open a device before someone has typed in the phone's passcode for the first time since being turned on. It also shows Cellebrite's capabilities against after first unlock, or AFU, devices. The Support Matrix also shows Cellebrite's capabilities against Pixel devices running GrapheneOS, with some differences between phones running that operating system and stock Android. Cellebrite does support, for example, Pixel 9 devices BFU. Meanwhile the screenshot indicates Cellebrite cannot unlock Pixel 9 devices running GrapheneOS BFU. In their forum post, rogueFed wrote that the "meeting focused specific on GrapheneOS bypass capability." They added "very fresh info more coming."

You Only Need $750 to Pilfer Unencrypted Data From Satellites, Researchers Say

18 octobre 2025 à 21:48
"A new study published on Monday found that communications from cellphone carriers, retailers, banks, and even militaries are being broadcast unencrypted through geostationary satellites..." reports Gizmodo. "The team obtained unencrypted internet communications from U.S. military sea vessels and even communications regarding narcotics trafficking from Mexican military and law enforcement." Researchers from the University of California, San Diego (UCSD) and the University of Maryland scanned 39 of these satellites from a rooftop in Southern California over three years. They found that roughly half of the signals they analyzed were transmitting unencrypted data, potentially exposing everything from phone calls and military logistics to a retail chain's inventory. "There is a clear mismatch between how satellite customers expect data to be secured and how it is secured in practice," the researchers wrote in their paper titled "Don't Look Up: There Are Sensitive Internal Links in the Clear on GEO Satellites...." "They assumed that no one was ever going to check and scan all these satellites and see what was out there. That was their method of security," Aaron Schulman, a UCSD professor and co-lead of the study, told Wired.... Even more surprisingly, the researchers didn't need any fancy spy gear to collect this data. Their setup used only off-the-shelf hardware, including a $185 satellite dish, a $140 roof mount with a $195 motor, and a $230 tuner card. Altogether, the system cost roughly $750 and was installed on a university building in La Jolla, San Diego. With their simple setup, the researchers were able to collect a wide range of communication data, including phone calls, texts, in-flight Wi-Fi data from airline passengers, and signals from electric utilities. They even obtained U.S. and Mexican military and law enforcement communications, as well as ATM transactions and corporate communications... When it came to telecoms, specifically, the team collected phone numbers, calls, and texts from customers of T-Mobile, AT&T Mexico, and Telmex... It only took the team nine hours to collect the phone numbers of over 2,700 T-Mobile users, along with some of their calls and text messages. T-Mobile told Gizmodo the lack of encryption was "a vendor's technical misconfiguration" affecting "a limited number of cell sites" and was "not network-wide... [W]e implemented nationwide Session Initiation Protocol (SIP) encryption for all customers to further protect signaling traffic as it travels between mobile handsets and the network core, including call set up, numbers dialed and text message content. We appreciate our collaboration with the security research community, whose work helps reinforce our ongoing commitment to protecting customer data and enhances security across the industry." Indeed, the researchers write that "Each time we discovered sensitive information in our data, we went through considerable effort to determine the responsible party, establish contact, and disclose the vulnerability. In several cases, the responsible party told us that they had deployed a remedy. For the following parties, we re-scanned with their permission and were able to verify a remedy had been deployed: T-Mobile, WalMart, and KPU." The researchers acknowledge that exposure "was limited to a relatively small number of cell towers in specific remote areas."

Apple, Samsung Report Underwhelming Sales of Their New Thin Smartphones

18 octobre 2025 à 10:00
In two separate reports, Apple and Samsung are said to report underwhelming sales of their new ultra-thin smartphones. According to The Elec, Apple plans to cut production of the iPhone Air while Samsung has canceled its planned Galaxy S26 Edge smartphone after disappointing sales of the Galaxy S25 Edge, Korea's NewsPim claims. MacRumors reports: Samsung apparently halted work on the Galaxy S26 Edge this week, informing employees internally that the product line would be discontinued. Internal discussions in September shifted priorities toward the more conventional "Plus" form factor after confirming that consumer demand for ultra-slim flagships was weaker than expected. [...] Samsung will apparently instead add a Galaxy S26 Plus model to its 2026 lineup, reverting to the company's traditional three-tier structure of base, Plus, and Ultra variants. Despite the cancellation, development of the Galaxy S26 Edge was already complete. Development of the S26 Plus is expected to begin before the end of the third quarter of 2025. The atmosphere inside the company is said to be "chaotic" and "embarrassed" following the sudden lineup revision. Samsung reportedly plans to sell through existing inventory of the Galaxy S25 Edge and cease further production once stock is depleted. As for Apple's iPhone Air, here's what MacRumors is reporting: The Japanese investment banking and securities firm claims that the iPhone 17 Pro and iPhone 17 Pro Max are seeing higher sales than their predecessors during the same period last year, while the standard iPhone 17 is a major success, performing significantly better than the iPhone 16. The iPhone Air is apparently the outlier; Apple plans to reduce production by one million units this year. Meanwhile, Apple plans to increase production of all other models by two million units. The overall production forecast of the iPhone 17 series this year has also been increased from 88 million units to 94 million units for the start of 2026.

More Screen Time Linked To Lower Test Scores For Elementary Students

An anonymous reader quotes a report from CBC News: The study by a team from Toronto's Hospital for Sick Children (also known as Sick Kids) and St. Michael's Hospital was published in the Journal of the American Medical Association. It found that children who spent more time on screens before age eight scored lower on standardized tests. Child psychiatry researchers say handing kids digital devices, like iPads, every time they have a tantrum could lead to future issues. One new study links too much screen time to emotional and anger management problems. The study followed more than 3,000 kids in Ontario over a 15 year span from 2008 to 2023, tracking how much time they spent watching TV or DVDs, playing video games, using the computer or playing on handheld devices like iPads, as reported by their parents. That data was compared to their EQAO standardized test scores, which are used to assess the reading and math skills of kids across Ontario in grades 3 and 6. The findings point to a "significant association," between screen use and lower test scores, according to Dr. Catherine Birken, a pediatrician and senior scientist at Sick Kids and lead author of the study. "For each additional hour of screen use, there was approximately a 10 percent lower odds of meeting standards in both reading and mathematics ... in Grade 3 and mathematics in Grade 6," said Dr. Catherine Birken, a pediatrician and senior scientist at Sick Kids and lead author of the study, in an interview with CBC News. The study didn't differentiate between different types of screen time -- for example, whether a child was playing a game on their iPad versus FaceTiming a relative in another city, or watching an educational video. It was also an observational study that relied on parents answering questionnaires about how much time their kids spent in front of screens. The study authors note that this means the research can't be taken as definitive proof that screen time causes lower grades, just that the two things tend to go hand in hand.

Your Next Phone Might Come Without a USB Cable

Android Authority notes the start of a new trend we're seeing in some new smartphones: devices shipping without USB cables. It follows the earlier industry shift away from bundled charging bricks, which Apple started back in 2020 with the launch of the iPhone 12. While manufacturers cite environmental benefits, "the main driver behind these decisions for companies like Apple and Sony is, of course, profit," writes Android Authority's Taylor Kerns. From the report: Now, it looks like we may be in for a similar shift with bundled USB cables. As shared on the Linus Tech Tips subreddit, user Brick_Fish's recently purchased Sony Xperia 10 VII came without a charger or a charging cable. In a photo included with the post, you can see iconography on the back of the phone's box that spells out these omissions. Sony's not really a major player in the smartphone space these days, but this seems like the type of trend we should expect to see gain traction over the next couple of years. [...] Apple actually beat Sony to the punch here, in a way. The company's latest earbuds, the AirPods 4 and AirPods Pro 3, both ditched bundled USB cables, as well. Still, Sony's the first manufacturer I've heard of to omit charging cables with its smartphones.

Thwarted Plot To Cripple Cell Service In NY Was Bigger Than First Thought

Last month, federal investigators said they dismantled a China-linked plot that aimed to cripple New York City's telecommunications system by overloading cell towers, jamming 911 calls, and disrupting communications. According to law enforcement sources, the plot was even bigger than first thought. "Agents from Homeland Security Investigations found an additional 200,000 SIM cards at a location in New Jersey," according to ABC News. "That's double the 100,000 SIM cards, along with hundreds of servers, that were recently seized at five other vacant offices and apartments in and around the city." From the report: Investigators secured each of those locations, seized the electronics, and are now trying to track down who rented the spaces and filled them with shelves full of gear capable of sending 30 million anonymous text messages every minute, overloading communications and blacking out cellular service in a city that relies on it for emergency response and counterterrorism. According to sources, the investigation began after several high-level people, including at least one with direct access to President Donald Trump, were targeted not only by swatters but also with actual threats received on their private phones. "The potential threat these data centers pose to the public could include shutting down critical resources that the public needs, like the 911 system, or potentially impacting the public's ability to communicate everything, including business transactions," said Don Mihalek, an ABC News contributor who was formerly with the Secret Service.
