A New Generation Is Uncovering the Tiny Doodles Left By Engineers On Old Microchips (npr.org) 24

An anonymous reader quotes a report from NPR: An owl. A sharky looking bullet. The Hindu deity Ganesh. The Yin and Yang sign. All painstakingly selected and etched onto a microchip that measures about an inch square. Each microscopic silicon doodle was the handiwork of engineers at Qualcomm Incorporated, a San Diego-based company that creates wireless technology-related products and services. The engineers slipped the drawings into Qualcomm's Q1650 data decoder with care not to disturb any of the chip's functions. They were purposeless etchings, never meant to be uncovered.

These doodles, also known as silicon art, chip graffiti or chip art, and dozens others like it, are remnants of tech history -- from Silicon Valley's infancy to the early 2000s -- when innovation was rapid fire and the tech still had a very human touch. Engineers would add the sketches to their microchip designs in the techie equivalent of signing their artwork. They'd etch them on chips that may end up in your cellphone, laptop or calculator. They spent hours crafting them, even though they were frowned upon by those in the C Suite.

The existence of these doodles came to light decades ago, but social media is discovering them anew. And there is now a small but determined group of online hobbyists working to keep that history alive. They are still cataloguing the miniscule drawings -- many smaller than the width of a human hair and can't be seen without a microscope. These devotees post glossy videos of themselves shucking chips like oysters to see their iridescent insides and the itsy bitsy sketches that may be hidden on them. And they are eagerly saving them from the scrap heap.

Fairphone's Fairbuds Are True Wireless Earbuds With Repairable Design, User-Replaceable Batteries (liliputing.com) 75

Fairphone, the Dutch smartphone maker known for its user-repairable smartphones, is bringing its ultra-repairable design philosophy to their "Fairbuds" wireless earbuds. Liliputing reports: The Fairbuds have the sort of features we've come to expect from premium earbuds. They're noise-cancelling Bluetooth 5.3 earbuds with support for wind noise reduction and an environmental noise-cancelling feature that sets noise reduction depending on your environment. Fairphone's earbuds have six microphones, 11mm drivers, and an IP54 rating for water (and sweat) resistance. They also support multipoint connectivity, which means you can connect the earbuds to two different devices at the same time (like your phone and your laptop).

The earbuds offer up to 6 hours of battery life and they come with a charging case that gives you another 20 hours of use between charges. And Fairphone offers iOS and Android apps that let you adjust EQ, install firmware updates, and make other changes. Other features include automatic play and pause when the Fairbuds are removed from your ears, capacitive touch controls, and three different ear tips sizes included in the box.

But the key thing that makes these earbuds different from the competition is that they're designed to be repairable rather than replaceable. Lose just one earbud? Fairphone will let you buy a single earbud without paying again for a full set with a case. Is your battery life degrading a few years after purchase? Fairphone will sell battery replacements and let you swap out the batteries in your earbuds or charging case. All told, the company offers seven repairable/replaceable components for the Fairbuds. The company also offers a 3-year warranty for its new Fairbuds and notes that they're manufactured using:

- 70% of all materials used in production are fair and recycled (fair = ethically sourced).
- 100% of rare earth elements used are recycled.
- Plastics used in the Fairbuds and their charging case are recycled.
The Fairbuds are currently only available in Europe for 149 euros.

Feds Finally Decide To Do Something About Years-Old SS7 Spy Holes In Phone Networks 32

Jessica Lyons reports via The Register: The FCC appears to finally be stepping up efforts to secure decades-old flaws in American telephone networks that are allegedly being used by foreign governments and surveillance outfits to remotely spy on and monitor wireless devices. At issue are the Signaling System Number 7 (SS7) and Diameter protocols, which are used by fixed and mobile network operators to enable interconnection between networks. They are part of the glue that holds today's telecommunications together. According to the US watchdog and some lawmakers, both protocols include security weaknesses that leave folks vulnerable to unwanted snooping. SS7's problems have been known about for years and years, as far back as at least 2008, and we wrote about them in 2010 and 2014, for instance. Little has been done to address these exploitable shortcomings.

SS7, which was developed in the mid-1970s, can be potentially abused to track people's phones' locations; redirect calls and text messages so that info can be intercepted; and spy on users. The Diameter protocol was developed in the late-1990s and includes support for network access and IP mobility in local and roaming calls and messages. It does not, however, encrypt originating IP addresses during transport, which makes it easier for miscreants to carry out network spoofing attacks. "As coverage expands, and more networks and participants are introduced, the opportunity for a bad actor to exploit SS7 and Diameter has increased," according to the FCC [PDF].

On March 27 the commission asked telecommunications providers to weigh in and detail what they are doing to prevent SS7 and Diameter vulnerabilities from being misused to track consumers' locations. The FCC has also asked carriers to detail any exploits of the protocols since 2018. The regulator wants to know the date(s) of the incident(s), what happened, which vulnerabilities were exploited and with which techniques, where the location tracking occurred, and -- if known -- the attacker's identity. This time frame is significant because in 2018, the Communications Security, Reliability, and Interoperability Council (CSRIC), a federal advisory committee to the FCC, issued several security best practices to prevent network intrusions and unauthorized location tracking. Interested parties have until April 26 to submit comments, and then the FCC has a month to respond.

Researchers Unlock Fiber Optic Connection 1.2 Million Times Faster Than Broadband (popsci.com) 49

An anonymous reader quotes a report from Popular Science: In the average American house, any download rate above roughly 242 Mbs is considered a solidly speedy broadband internet connection. That's pretty decent, but across the Atlantic, researchers at UK's Aston University recently managed to coax about 1.2 million times that rate using a single fiber optic cable -- a new record for specific wavelength bands. As spotted earlier today by Gizmodo, the international team achieved a data transfer rate of 301 terabits, or 301,000,000 megabits per second by accessing new wavelength bands normally unreachable in existing optical fibers -- the tiny, hollow glass strands that carry data through beams of light. According to Aston University's recent profile, you can think of these different wavelength bands as different colors of light shooting through a (largely) standard cable.

Commercially available fiber cabling utilizes what are known as C- and L-bands to transmit data. By constructing a device called an optical processor, however, researchers could access the never-before-used E- and S-bands. "Over the last few years Aston University has been developing optical amplifiers that operate in the E-band, which sits adjacent to the C-band in the electromagnetic spectrum but is about three times wider," Ian Phillips, the optical processor's creator, said in a statement. "Before the development of our device, no one had been able to properly emulate the E-band channels in a controlled way." But in terms of new tech, the processor was basically it for the team's experiment. "Broadly speaking, data was sent via an optical fiber like a home or office internet connection," Phillips added. What's particularly impressive and promising about the team's achievement is that they didn't need new, high-tech fiber optic lines to reach such blindingly fast speeds. Most existing optical cables have always technically been capable of reaching E- and S-bands, but lacked the equipment infrastructure to do so. With further refinement and scaling, internet providers could ramp up standard speeds without overhauling current fiber optic infrastructures.

'Smart Devices Are Turning Out To Be a Poor Investment' (androidpolice.com) 155

An anonymous reader quotes a report from Android Police, written by Dhruv Bhutani: As someone who is an early adopter of all things smart and has invested a significant amount of money in building a fancy smart home, it saddens me to say that I feel cheated by the thousands of dollars I've spent on smart devices. And it's not a one-off. Amazon's recent move to block off local ADB connections on Fire TV devices is the latest example in a long line of grievances. A brand busy wrestling away control from the consumer after they've bought the product, the software update gimps a feature that has been present on the hardware ever since it launched back in 2014. ADB-based commands let users take deep control of the hardware, and in the case of the Fire TV hardware, it can drastically improve the user experience. [...] A few years ago, I decided to invest in the NVIDIA Shield. The premium streamer was marketed as a utopia for streaming online and offline sources with the ability to plug in hard drives, connect to NAS drives, and more. At launch, it did precisely that while presenting a beautiful, clean interface that was a joy to interact with. However, subsequent updates have converted what was otherwise a clean and elegant solution to an ad-infested overlay that I zoom past to jump into my streaming app of choice. This problem isn't restricted to just the Shield. Even my Google TV running Chromecast has a home screen that's more of an advertising space for Google than an easy way to get to my content.

But why stop at streaming boxes? Google's Nest Hubs are equal victims of feature deterioration. I've spent hundreds of dollars on Nest Hubs and outfitted them in most of my rooms and washrooms. However, Google's consistent degradation of the user experience means I use these speakers for little more than casting music from the Spotify app. The voice recognition barely works on the best of days, and when it does, the answers tend to be wildly inconsistent. It wasn't always the case. In fact, at launch, Google's Nest speakers were some of the best smart home interfaces you could buy. You'd imagine that the experience would only improve from there. That's decidedly not the case. I had high hopes that the Fuchsia update would fix the broken command detection, but that's also not the case. And good luck to you if you decided to invest in Google Assistant-compatible displays. Google's announcement that it would no longer issue software or security updates to third-party displays like the excellent Lenovo Smart Display, right after killing the built-in web browser, is pretty wild. It boggles my mind that a company can get away with such behavior.

Now imagine the plight of Nest Secure owners. A home security system isn't something one expects to switch out for many many years. And yet, Google decided to kill the Nest Secure home monitoring solution merely three years after launching the product range. While I made an initial investment in the Nest ecosystem, I've since switched over to a completely local solution that is entirely under my control, stores data locally, and won't be going out of action because of bad decision-making by another company.
"It's clear to me that smart home devices, as they stand, are proving to be very poor investments for consumers," Bhutani writes in closing. "Suffice it to say that I've paused any future investments in smart devices, and I'll be taking a long and hard look at a company's treatment of its current portfolio before splurging out more cash. I'd recommend you do the same."

How Apple Plans To Update New iPhones Without Opening Them (arstechnica.com) 97

An anonymous reader writes: What if you could update the device while it's still in the box? That's the latest plan cooked up by Apple, which is close to rolling out a system that will let Apple Stores wirelessly update new iPhones while they're still in their boxes. The new system is called "Presto." French site iGeneration has the first picture of what this setup looks like. It starts with a clearly Apple-designed silver rack that holds iPhones and has a few lights on the front. The site (through translation) calls the device a "toaster," and yes, it looks like a toaster oven or food heating rack.

Bloomberg's Mark Gurman has been writing about whispers of this project for months, saying in one article that the device can "wirelessly turn on the iPhone, update its software and then power it back down -- all without the phone's packaging ever being opened." In another article, he wrote that the device uses "MagSafe and other wireless technologies." The iGeneration report also mentions that the device uses NFC, and there are "templates" that help with positioning the various-sized iPhone boxes so the NFC and wireless charging will work. With that wireless charging, downloading, and installing, all while being isolated in a cardboard box, Apple's "toaster" probably gets pretty hot.

Landlines Are Dying Out (yahoo.com) 142

An anonymous reader shares a report: The number of landline users has plummeted with the rise of cellphones, and the 19th-century technology's days appear to be numbered. Providers like AT&T are looking to exit the business by transitioning customers to cellphones or home telephone service over broadband connections. But for many of the millions of people still clinging to their copper-based landline telephones, newer alternatives are either unavailable, too expensive, or are unreliable when it matters most: in an emergency.

According to the National Center for Health Statistics, only a quarter of adults in the United States still have landlines and only around 5 percent say they mostly or only rely on them. The largest group of people holding onto their landlines are 65 and older. Meanwhile, more than 70 percent of adults are using wireless phones only. The copper lines used for traditional landlines carry electricity over the wires, so as long as a phone is corded or charged it will work during a power outage. Landlines are separate from cellular and broadband networks and are not affected by their outages, making them a necessary backstop in rural areas. Many of those same areas have inadequate cellular or internet coverage.

"In three, four, maybe five years a lot of states are going to say 'Okay, it's permissible to discontinue service if you, the phone company, can demonstrate there's functional alternative service,'" says Rob Frieden, an Academy and Emeritus Professor of Telecommunications and Law at Pennsylvania State University. AT&T recently asked the California Public Utilities Commission to end its obligation to provide landline service in parts of the state. The Federal Communications Commission, which has to approve a request to end service, said it hasn't received one from AT&T.

Truck-To-Truck Worm Could Infect Entire US Fleet (theregister.com) 50

Jessica Lyons reports via The Register: Vulnerabilities in common Electronic Logging Devices (ELDs) required in US commercial trucks could be present in over 14 million medium- and heavy-duty rigs, according to boffins at Colorado State University. In a paper presented at the 2024 Network and Distributed System Security Symposium, associate professor Jeremy Daily and systems engineering graduate students Jake Jepson and Rik Chatterjee demonstrated how ELDs can be accessed over Bluetooth or Wi-Fi connections to take control of a truck, manipulate data, and spread malware between vehicles. "These findings highlight an urgent need to improve the security posture in ELD systems," the trio wrote [PDF].

The authors did not specify brands or models of ELDs that are vulnerable to the security flaws they highlight in the paper. But they do note there's not too much diversity of products on the market. While there are some 880 devices registered, "only a few tens of distinct ELD models" have hit the road in commercial trucks. A federal mandate requires most heavy-duty trucks to be equipped with ELDs, which track driving hours. These systems also log data on engine operation, vehicle movement and distances driven -- but they aren't required to have tested safety controls built in. And according to the researchers, they can be wirelessly manipulated by another car on the road to, for example, force a truck to pull over.

The academics pointed out three vulnerabilities in ELDs. They used bench level testing systems for the demo, as well as additional testing on a moving 2014 Kenworth T270 Class 6 research truck equipped with a vulnerable ELD. [...] For one of the attacks, the boffins showed how anyone within wireless range could use the device's Wi-Fi and Bluetooth radios to send an arbitrary CAN message that could disrupt of some of the vehicle's systems. A second attack scenario, which also required the attacker to be within wireless range, involved connecting to the device and uploading malicious firmware to manipulate data and vehicle operations. Finally, in what the authors described as the "most concerning" scenario, they uploaded a truck-to-truck worm. The worm uses the compromised device's Wi-Fi capabilities to search for other vulnerable ELDs nearby. After finding the right ELDs, the worm uses default credentials to establish a connection, drops its malicious code on the next ELD, overwrites existing firmware, and then starts the process over again, scanning for additional devices. "Such an attack could lead to widespread disruptions in commercial fleets, with severe safety and operational implications," the researchers warned.

US Broadband Providers To Begin Providing New Comparison Labels (reuters.com) 19

Major U.S. broadband internet providers must start displaying information similar to nutrition labels on food products to help consumers shop for services starting on April 10, under new rules from the Federal Communications Commission. From a report: Verizon Communications said it will begin providing the labels on Wednesday. The FCC first moved to mandate the labels in 2022. Smaller providers will be required to provide labels starting in October. The rules require broadband providers to display, at the point of sale, labels that show prices, speeds, fees and data allowances for both wireless and wired products. Verizon Chief Customer Experience Officer Brian Higgins said in an interview the labels will help consumers make "an equal comparison" between product offerings, speeds and fees.

Higgins said standardized labels across the industry "make it easier for customers to do a comparison of which provider is going to be the best fit for their needs." He said customers will still need to research various bundling offers across carriers. The labels were first unveiled as a voluntary program in 2016. Congress ordered the FCC to mandate them under the 2021 infrastructure law. "Consumers will finally get information they can use to comparison shop, avoid junk fees, and make informed choices about which high-speed internet service is the best fit for their needs and budget," FCC Chair Jessica Rosenworcel said.

Why Are So Many AI Chatbots 'Dumb as Rocks'? (msn.com) 73

Amazon announced a new AI-powered chatbot last month — still under development — "to help you figure out what to buy," writes the Washington Post. Their conclusion? "[T]he chatbot wasn't a disaster. But I also found it mostly useless..."

"The experience encapsulated my exasperation with new types of AI sprouting in seemingly every technology you use. If these chatbots are supposed to be magical, why are so many of them dumb as rocks?" I thought the shopping bot was at best a slight upgrade on searching Amazon, Google or news articles for product recommendations... Amazon's chatbot doesn't deliver on the promise of finding the best product for your needs or getting you started on a new hobby.

In one of my tests, I asked what I needed to start composting at home. Depending on how I phrased the question, the Amazon bot several times offered basic suggestions that I could find in a how-to article and didn't recommend specific products... When I clicked the suggestions the bot offered for a kitchen compost bin, I was dumped into a zillion options for countertop compost products. Not helpful... Still, when the Amazon bot responded to my questions, I usually couldn't tell why the suggested products were considered the right ones for me. Or, I didn't feel I could trust the chatbot's recommendations.

I asked a few similar questions about the best cycling gloves to keep my hands warm in winter. In one search, a pair that the bot recommended were short-fingered cycling gloves intended for warm weather. In another search, the bot recommended a pair that the manufacturer indicated was for cool temperatures, not frigid winter, or to wear as a layer under warmer gloves... I did find the Amazon chatbot helpful for specific questions about a product, such as whether a particular watch was waterproof or the battery life of a wireless keyboard.

But there's a larger question about whether technology can truly handle this human-interfacing task. "I have also found that other AI chatbots, including those from ChatGPT, Microsoft and Google, are at best hit-or-miss with shopping-related questions..." These AI technologies have potentially profound applications and are rapidly improving. Some people are making productive use of AI chatbots today. (I mostly found helpful Amazon's relatively new AI-generated summaries of customer product reviews.)

But many of these chatbots require you to know exactly how to speak to them, are useless for factual information, constantly make up stuff and in many cases aren't much of an improvement on existing technologies like an app, news articles, Google or Wikipedia. How many times do you need to scream at a wrong math answer from a chatbot, botch your taxes with a TurboTax AI, feel disappointed at a ChatGPT answer or grow bored with a pointless Tom Brady chatbot before we say: What is all this AI junk for...?

"When so many AI chatbots overpromise and underdeliver, it's a tax on your time, your attention and potentially your money," the article concludes.

"I just can't with all these AI junk bots that demand a lot of us and give so little in return."

SpaceX Gets E-Band Radio Waves To Boost Starlink Broadband (spacenews.com) 26

Jason Rainbow reports via SpaceNews: SpaceX has secured conditional approval to use extremely high-frequency E-band radio waves to improve the capacity of its low Earth orbit Starlink broadband constellation. The Federal Communications Commission said March 8 it is allowing SpaceX to use E-band frequencies between second-generation Starlink satellites and gateways on the ground, alongside already approved spectrum in the Ka and Ku bands. Specifically, SpaceX is now also permitted to communicate between 71 and 76 gigahertz from space to Earth, and 81-86 GHz Earth-to-space, using the up to 7,500 Gen2 satellites SpaceX is allowed to deploy.

SpaceX has plans for 30,000 Gen2 satellites, on top of the 4,400 Gen1 satellites already authorized by the FCC. However, the FCC deferred action in December 2022 on whether to allow SpaceX to deploy the other three-quarters of its Gen2 constellation, which includes spacecraft closer to Earth to improve broadband speeds. The regulator also deferred action at the time on SpaceX's plans to use E-band frequencies, citing a need to first establish ground rules for using them in space. In a March 8 regulatory filing, the FCC said it found "SpaceX's proposed operations in the E-band present no new or increased frequency conflicts with other satellite operations." But the order comes with multiple conditions, including potentially forcing SpaceX to modify operations if another satellite operator also seeks to use the radio waves.

Google's Newest Office Has AI Designers Toiling In a Wi-Fi Desert (reuters.com) 85

Google's swanky new office building located on the Alphabet's Mountain View, California headquarters has been "plagued for months by inoperable, or, at best, spotty Wi-Fi," reports Reuters citing six people familiar with the matter. "Its recliner-laden collaborative workspaces do not work well for teams carting around laptops, since workers must plug into ethernet cables at their desks to get consistent internet service. Some make do by using their phones as hotspots." From the report: The company promoted the new building and surrounding campus in a 229-page glossy book highlighting its cutting-edge features, such as "Googley interiors" and "an environment where everyone has the tools they need to be successful."

But, a Google spokeswoman acknowledged, "we've had Wi-Fi connectivity issues in Bay View." She said Google "made several improvements to address the issue," and the company hoped to have a fix in coming weeks. According to one AI engineer assigned to the building, which also houses members of the advertising team, the wonky Wi-Fi has been no help for Google pushing a three day per week return-to-office mandate. "You'd think the world's leading internet company would have worked this out," he said.

Managers have encouraged workers to stroll outside or sit at the adjoining cafe where the Wi-Fi signal is stronger. Some were issued new laptops recently with more powerful Wi-Fi chips. Google has not publicly disclosed the reasons for the Wi-Fi problems, but workers say the 600,000-square-foot building's swooping, wave-like rooftop swallows broadband like the Bermuda Triangle.

6G Principles Endorsed By US and International Partners (axios.com) 19

The U.S. and several international partners endorsed shared principles for developing 6G wireless communication systems, the White House said Monday. From a report: A battle is underway to influence the standards of 6G amid concerns by Western countries and their allies that authoritarian regimes could gain further control over Internet in their countries. Policies around wireless communications influence economic-growth and national security, fueling the race between the U.S. and China -- which claimed earlier this month that it had launched the world's first satellite "to test 6G architecture," per state media.

The governments of the U.S., Australia, Canada, the Czech Republic, Finland, France, Japan, South Korea, Sweden and the U.K. released a joint statement saying that by working together, "we can support open, free, global, interoperable, reliable, resilient, and secure connectivity." They laid out principles including using systematic approaches to cybersecurity, being protective of privacy and creating technologies that are widely available and accessible to developing nations.

'Every PC Is Going To Be an AI PC' 102

During a briefing at Mobile World Congress in Barcelona, Meghana Patwardhan, VP of Commercial Mobility at Dell Technology, told The Register that while the immediate future would consist of two worlds -- one with AI hardware and one without -- "every PC is going to be an AI PC in the longer term." From the report: In terms of new hardware, Dell used the Mobile World Congress event in Barcelona to show off new versions of its Surface-baiting Latitude 7350 convertible -- "the world's most serviceable commercial detachable," according to the company -- and its workstation-class Precision 3680 tower. Other devices in the Precision range include mobile workstations and the 3280 Compact Form Factor PC. Dell was also determined to present itself as a leader in hybrid working with the Premier Wireless ANC headset, replete with AI-based noise cancellation.

Duringt our talk, AI was never far from the lips of Dell's spokespeople as the company talked up the energy efficiency and future-proofing it saw in dedicated AI hardware, such as Neural Processing Units (NPUs) that are increasingly cropping up in CPUs. To illustrate the point, Dell boatsed about how much more efficient background blurring is on video calls when AI hardware is running compared to when it isn't. Hopefully, Microsoft will soon deliver a version of Windows capable of demonstrating a use for AI hardware that is more than hiding distractions in the background.

AT&T Will Issue $5 Reimbursements For 12-Hour Outage (cnn.com) 45

CNN reports: AT&T is reimbursing customers for the nearly 12-hour network outage on Thursday, the company announced in a news release. The mobile network will issue a $5 credit to "potentially impacted" AT&T Wireless customers, which it says is the "average cost of a full day of service."
The credit will be applied automatically "within 2 bill cycles," according to an announcement at the URL att.com/makeitright. "We recognize the frustration this outage has caused and know we let many of our customers down."

In a much smaller font, they note that the credit "does not apply to AT&T Business, AT&T Prepaid or Cricket.

More from CNN: AT&T had encountered sporadic service interruptions in the days leading up to the outage, including a temporary 911 outage in some parts of the southeast. While regional disruptions to wireless service happen occasionally, prolonged nationwide outages are rare. The Federal Communications Commission confirmed Thursday it was investigating the incident...

Several hours after service was restored, AT&T released an update stating the outage seemed to be the result of an internal issue, not a cybersecurity threat. "Based on our initial review, we believe that today's outage was caused by the application and execution of an incorrect process used as we were expanding our network," the company said.

On Saturday, AT&T reiterated it was taking steps "to prevent this from happening again in the future," but did not elaborate.

AT&T Restores Service After Massive, Nationwide Outage (cnn.com) 55

An anonymous reader quotes a report from CNN Business: AT&T's network went down for many of its customers across the United States Thursday morning, leaving customers unable to place calls, text or access the internet. By a little after 3 pm ET, roughly 11 hours after reports of the outage first emerged, the company said that it had restored service to all impacted customers. "We have restored wireless service to all our affected customers. We sincerely apologize to them," AT&T said in a statement. The company added that it is "taking steps to ensure our customers do not experience this again in the future."

The Federal Communications Commission confirmed Thursday afternoon that it is investigating the outage. The White House says federal agencies are in touch with AT&T about network outages but that it doesn't have all the answers yet on what exactly led to the interruptions. Although Verizon and T-Mobile customers reported some network outages, too, they appeared far less widespread. T-Mobile and Verizon said their networks were unaffected by AT&T's service outage and customers reporting outages may have been unable to reach customers who use AT&T.

Thursday morning, more than 74,000 AT&T customers reported outages on digital-service tracking site DownDetector, with service disruptions beginning around 4 am ET. That's not a comprehensive number: It tracks only self-reported outages. Reports had been rising steadily throughout the morning but leveled off in the 9 am ET hour. By 12:30 pm ET, the DownDetector data showed some 25,000 AT&T customers still reporting outages. By 2 pm ET, fewer than 5,000 customers were still reporting issues. Earlier Thursday, AT&T acknowledged that it had a widespread outage but did not provide a reason for the system failure. By late morning, AT&T said most of its network was back online, and it confirmed Thursday afternoon that service was fully restored.
According to an anonymous industry source, the issue for the outage appears to be related to how cellular services hand off calls from one network to the next, a process known as peering. They said there's no indication that it was the result of a cyberattack or other malicious activity.

The FCC confirmed that it is investigating the incident. "We are aware of the reported wireless outages, and our Public Safety and Homeland Security Bureau is actively investigating," the FCC said in a statement posted on X. "We are in touch with AT&T and public safety authorities, including FirstNet, as well as other providers."

MIT Researchers Build Tiny Tamper-Proof ID Tag Utilizing Terahertz Waves (mit.edu) 42

A few years ago, MIT researchers invented a cryptographic ID tag — but like traditional RFID tags, "a counterfeiter could peel the tag off a genuine item and reattach it to a fake," writes MIT News.

"The researchers have now surmounted this security vulnerability by leveraging terahertz waves to develop an antitampering ID tag that still offers the benefits of being tiny, cheap, and secure." They mix microscopic metal particles into the glue that sticks the tag to an object, and then use terahertz waves to detect the unique pattern those particles form on the item's surface. Akin to a fingerprint, this random glue pattern is used to authenticate the item, explains Eunseok Lee, an electrical engineering and computer science (EECS) graduate student and lead author of a paper on the antitampering tag. "These metal particles are essentially like mirrors for terahertz waves. If I spread a bunch of mirror pieces onto a surface and then shine light on that, depending on the orientation, size, and location of those mirrors, I would get a different reflected pattern. But if you peel the chip off and reattach it, you destroy that pattern," adds Ruonan Han, an associate professor in EECS, who leads the Terahertz Integrated Electronics Group in the Research Laboratory of Electronics.

The researchers produced a light-powered antitampering tag that is about 4 square millimeters in size. They also demonstrated a machine-learning model that helps detect tampering by identifying similar glue pattern fingerprints with more than 99 percent accuracy. Because the terahertz tag is so cheap to produce, it could be implemented throughout a massive supply chain. And its tiny size enables the tag to attach to items too small for traditional RFIDs, such as certain medical devices...

"These responses are impossible to duplicate, as long as the glue interface is destroyed by a counterfeiter," Han says. A vendor would take an initial reading of the antitampering tag once it was stuck onto an item, and then store those data in the cloud, using them later for verification."

Seems like the only way to thwart that would be carving out the part of the surface where the tag was affixed — and then pasting the tag, glue, and what it adheres to all together onto some other surface. But more importantly, Han says they'd wanted to demonstrate "that the application of the terahertz spectrum can go well beyond broadband wireless."

In this case, you can use terahertz for ID, security, and authentication. There are a lot of possibilities out there."

Wi-Fi Jamming To Knock Out Cameras Suspected In Nine Minnesota Burglaries (tomshardware.com) 174

Mark Tyson reports via Tom's Hardware: A serial burglar in Edina, Minnesota is suspected of using a Wi-Fi jammer to knock out connected security cameras before stealing and making off with the victim's prized possessions. [...] Edina police suspect that nine burglaries in the last six months have been undertaken with Wi-Fi jammer(s) deployed to ensure incriminating video evidence wasnâ(TM)t available to investigators. The modus operandi of the thief or thieves is thought to be something like this:

- Homes in affluent areas are found - Burglars carefully watch the homes - The burglars avoid confrontation, so appear to wait until homes are empty - Seizing the opportunity of an empty home, the burglars will deploy Wi-Fi jammer(s) - "Safes, jewelry, and other high-end designer items," are usually taken

A security expert interviewed by the source publication, KARE11, explained that the jammers simply confused wireless devices rather than blocking signals. They usually work by overloading wireless traffic âoeso that real traffic cannot get through,â the news site was told. [...] Worryingly, Wi-Fi jamming is almost a trivial activity for potential thieves in 2024. KARE11 notes that it could buy jammers online very easily and cheaply, with prices ranging from $40 to $1,000. Jammers are not legal to use in the U.S. but they are very easy to buy online.

The US Government Makes a $42 Million Bet On Open Cell Networks (theverge.com) 26

An anonymous reader quotes a report from The Verge: The US government has committed $42 million to further the development of the 5G Open RAN (O-RAN) standard that would allow wireless providers to mix and match cellular hardware and software, opening up a bigger market for third-party equipment that's cheaper and interoperable. The National Telecommunications and Information Administration (NTIA) grant would establish a Dallas O-RAN testing center to prove the standard's viability as a way to head off Huawei's steady cruise toward a global cellular network hardware monopoly.

Verizon global network and technology president Joe Russo promoted the funding as a way to achieve "faster innovation in an open environment." To achieve the standard's goals, AT&T vice president of RAN technology Robert Soni says that AT&T and Verizon have formed the Acceleration of Compatibility and Commercialization for Open RAN Deployments Consortium (ACCoRD), which includes a grab bag of wireless technology companies like Ericsson, Nokia, Samsung, Dell, Intel, Broadcom, and Rakuten. Japanese wireless carrier Rakuten formed as the first O-RAN network in 2020. The company's then CEO, Tareq Amin, told The Verge's Nilay Patel in 2022 that Open RAN would enable low-cost network build-outs using smaller equipment rather than massive towers -- which has long been part of the promise of 5G.

But O-RAN is about more than that; establishing interoperability means companies like Verizon and AT&T wouldn't be forced to buy all of their hardware from a single company to create a functional network. For the rest of us, that means faster build-outs and "more agile networks," according to Rakuten. In the US, Dish has been working on its own O-RAN network, under the name Project Genesis. The 5G network was creaky and unreliable when former Verge staffer Mitchell Clarke tried it out in Las Vegas in 2022, but the company said in June last year that it had made its goal of covering 70 percent of the US population. Dish has struggled to become the next big cell provider in the US, though -- leading satellite communications company EchoStar, which spun off from Dish in 2008, to purchase the company in January.
The Washington Post writes that O-RAN "is Washington's anointed champion to try to unseat the Chinese tech giant Huawei Technologies" as the world's biggest supplier of cellular infrastructure gear.

According to the Post, Biden has emphasized the importance of O-RAN in conversations with international leaders over the past few years. Additionally, it notes that Congress along with the NTIA have dedicated approximately $2 billion to support the development of this standard.

Canada Moves To Ban the Flipper Zero Over Car Hacking Fears 63

It appears that the government of Canada is going to ban the Flipper Zero, the tiny, modular hacking device that's become popular with techies for its deviant digital powers. From a report: On Thursday, following a summit that focused on "the growing challenge of auto theft in Canada," the country's Minister of Innovation, Science and Industry posted a statement on X, saying "Criminals have been using sophisticated tools to steal cars...Today, I announced we are banning the importation, sale and use of consumer hacking devices, like flippers, used to commit these crimes.

In a press release issued on Thursday, the Canadian government confirmed that it will be pursuing "all avenues to ban devices used to steal vehicles by copying the wireless signals for remote keyless entry, such as the Flipper Zero." The Flipper, which is technically a penetration testing device, has been controversial due to its ability to hack droves of smart products. Alex Kulagin, the COO of Flipper Devices, said in a statement shared with Gizmodo that the device couldn't be used to "hijack any car" and that certain circumstances would have to be met for it to happen:
