Hackers control connected cars using text messages

It’s not only Chrysler drivers that have to worry about hackers taking control of their cars from afar. UC San Diego researchers have found that you can control features on cars of many makes by exploiting vulnerabilities in cellular-capable dongles that are sometimes plugged into the vehicles’ OBD-II ports, such as insurance trackers and driving efficiency tools . In the example you see above, the security team compromised a Corvette touting a Mobile Devices dongle (one of the most common varieties) through everyday text messages — they could turn on the wipers or even cut the brakes. That same device is also set to allow remote tunneling using a universal ‘private’ key, making it easy for an intruder to get complete control over the adapter and its unfortunate host car. You’ll be glad to hear that Mobile Devices has already patched its hardware in response to the findings, and that the phone numbers for these dongles aren’t normally public. You’d have to use brute force guesses to find a viable target. However, the concern is that other brands’ dongles still have holes, and that many of these gadgets aren’t getting updates in a timely fashion. It’s feasible that an intruder could cause chaos by either forcing vulnerable cars off the road or making life miserable for their occupants.

Verizon tests new fiber system that hits 10Gbps speeds

Verizon has announced that it has successfully completed field tests of its new super-fast fiber optic technology, dubbed the next-generation passive optical network (NG-PON2). It could offer users connectivity speeds anywhere from 10Gbps to 80Gbps some point “in the future”, according to a Verizon press release. The new system utilizes an optical line terminal (OLT) capable of generating four wavelengths of light, each of which is able to transmit at an eye-watering 10Gbps down and 2.5Gbps up. Interestingly, the network can actually transmit both the current GPON (Gigabit-capable Passive Optical Network) signal as well as this new NG-PON2 simultaneously. What’s more, should one of the wavelengths fail (due to, say, equipment failure), the system can reportedly switch over to one of the other three wavelengths to quickly restore the 10Gbps connection, a redundancy that should help improve the FIOS network’s reliability. The company sees its implementation as a necessary step for the upcoming shift to 4K video streaming. As such, Verizon will begin issuing “requests for proposals” for the hardware and software needed to upgrade its FIOS service later this year. There’s no word yet on when the service will actually come online but it will likely only be available to businesses at first. And even then, potentially only on the East Coast . By comparison, Comcast offers 2Gbps for $300 a month , and Google offers 1Gbps service for $70, both of which are already deployed throughout the country and available to personal and commercial users alike.

Quantum VJ puts a glitchy audio visualizer around your neck

Do pendants and other wearable ornaments lack pizzazz for you? Alexander Zolotov has a way to spice things up… if you’re fond of 8-bit graphics gone haywire , at least. His Quantum VJ is small enough to hang around your neck, but clever enough to turn audio into wonderfully glitchy visuals on its 128 x 64 OLED display. As you’ll see below, the result is at once modest yet mesmerizing — plug in some tunes and you’ll have a tiny, synchronized light show several inches away from your face. It runs for 20 hours on a typical coin-sized battery, too, so it can distract passers-by all day long. This is currently a one-of-a-kind device that doesn’t even have video out, but Zolotov tells The Creators Project that future models might have output. If so, you may one day have a dance party backdrop dangling around your chest.

Nano-sized ‘yolks’ should lead to longer-lasting batteries

Those eggs you might have had for breakfast? They’re not just food — they may be the key to longer-running batteries in your devices. Scientists at MIT and Tsinghua University have developed a nanoparticle battery electrode whose egg-like design is built to last. Their invention, which houses a shape-changing aluminum “yolk” in a titanium dioxide cell, can go through charging cycles without degrading like the graphite electrodes in conventional power packs. That could improve not only the overall longevity of the battery, but also its capacity and maximum power. You’d have gadgets that not only hold out for longer between charges, but don’t need to be replaced quite so often under heavy use. This is still a lab experiment, but it’s closer to practical reality than you think. The manufacturing technique is simple, and these materials are relatively easy to find. The yolks already hold up well under stress, for that matter. Even with super-fast charging (which typically shortens a battery’s lifespan), a test unit had just over half its capacity after 500 cycles. So long as the team does get its tech into a shipping product, you could see a wave of hardware that reduces many of your energy-related woes, such as range anxiety in electric cars or phone batteries that die before you’re ready to upgrade.

Phone companies ditching copper wires will have to follow the rules

The age of the copper land-line is nearing its end, but traditional phone lines aren’t going quietly: new rules from the FCC now require service providers notify customers of the impending removal and drawbacks of switching to a VOIP line three months before killing a copper network. It sounds like a reasonable move — customers need to know that the technology replacing their traditional land-line won’t work during a power-outage without an external power source — but not everybody at the FCC is happy with the new rules. “It appears that Chicken Little rules the roost, ” writes Commissioner Ajit Pai in a dissent to the updated transition rules. “By dragging out the copper retirement process , the FCC is adopting ‘regulations that deter rather than promote fiber deployment.'” Pai argues that the FCC is making it more difficult for companies to modernize their networks because lobbyists are claiming that retiring copper will cause the “sky to fall, ” disrupting services and hurting their business model. He has a point — but wouldn’t you want to be notified if the phone company was changing out your voice service worked? Check out the FCC’s official announcement at the source link below.

Toshiba’s new flash chips hold twice the data

Judging by recent announcements, we’re about to enter a golden age of fast, nearly unlimited storage for all the high-res selfies you can shoot. Following an announcement by Intel and Micron last week , Toshiba and partner SanDisk revealed their own 256Gb flash chips. Toshiba already has the smallest flash cells in the world at 15 nanometers, which it stacks in 48 layers to maximize density. The new chips add in 3-bit tech (first used by Samsung ) to squeeze even more bytes in, helping it double the storage of chips it announced just a few months ago. The result will be faster and more reliable memory for smartphones, SSDs and other devices. Intel and Micron announced 256Gb chips using different, 32-layer tech earlier this year , so they may beat Toshiba/SanDisk to the manufacturing punch. Consumers will be the main beneficiaries of the rivalry, in any case. Micron said the tech will eventually yield up to 10TB laptop drives at much lower prices per gigabyte than current models. It’ll also result in cheaper and faster memory chips for smartphones and other mobile devices. Toshiba’s in the process of building its new fab plant in Japan, and said the 256Gb chips will be available sometime in 2016. Filed under: Storage Comments Source: Toshiba

Huge malware campaign used Yahoo’s ad network

You’ve probably heard of malware-laden ads causing havoc on the web, but rarely on this scale. Malwarebytes has discovered a malware campaign that was using Yahoo’s ad network to target legions upon legions of visitors — Yahoo’s main site racks up 6.9 billion visits per month. While it’s not clear what would happen if you fell victim to an attack, the Flash-based exploit kit linked to the campaign typically includes both ad fraud and ransomware . In short, there’s a real chance that you could have been locked out of your PC simply by checking on your fantasy sports league . Notice the emphasis on the past tense, though. Yahoo was quick to take this “malvertising” campaign down, so you’re not at risk as I write this. Even so, it’s not exactly comforting that malware writers could even slip their code into such a large ad network. Yahoo’s still investigating what happened, but it appears that online ad giants may need stricter filters on what gets through.

OnStar hack remotely starts cars, GM working on a fix

Hacker Samy Kamkar unveiled his latest triumph this morning: OwnStar, a tiny box that acts as a Wi-Fi hotspot and intercepts commands sent from a driver’s OnStar RemoteLink app, allowing an unauthorized user to locate, unlock or start the vehicle. Simply place the box somewhere in an OnStar-connected car and wait for the driver to start up the RemoteLink app within range of the vehicle. The driver’s smartphone should automatically connect to OwnStar’s network and, voila , the hacker now has all of the car owner’s information (email, home address, final four digits on a credit card plus expiration date), and control of the car. GM has already issued one patch this morning aimed at securing the RemoteLink app, but it was unsuccessful, according to Kamkar . Kamkar never intended to wreak havok with OwnStar, he said in an interview with Wired . He wanted to expose a vulnerability in the OnStar app and help GM fix it — and it seems as if that’s precisely what’s happening. GM is working to patch the RemoteLink bug now and Kamkar says he’s in contact with the company as they fix it. Kamkar plans to reveal more technical details about OwnStar at Defcon 2015, which runs from August 6th to the 9th in Las Vegas. OwnStar update: GM told WIRED that OnStar bug was fixed, however it’s not actually resolved yet. I spoke with GM & they’re working on it now – Samy Kamkar (@samykamkar) July 30, 2015 This is the second major car-based hack to surface this month. On July 24th, Fiat Chrysler issued a voluntary recall of 1.4 million US vehicles with certain touchscreen entertainment systems, after Wired reported that it was possible to remotely cut the engine, disable and activate the brakes, and track the location of these cars.

US wants the world’s fastest supercomputer by 2025

President Obama has signed an executive order demanding that the US build the world’s fastest supercomputer by 2025. The National Strategic Computing Initiative has been implemented to get the country building an Exascale machine and not fall behind rival nations in the technological arms race. This supercomputer will be developed by arms of the federal government and then be harnessed to speed up research into a wide variety of topics. One example is that the hardware will be used to help NASA better understand turbulence for aircraft design, while another is to crunch the numbers for medical researchers. The US may have more of the Top 500 supercomputers than any other nation, but its prestige in this area is slipping to nations like China and Japan. China’s Tianhe-2 has been the world’s fastest machine for two and a half years in a row, and the list’s authors feel that the US approaching is plunging to a “historical low.” With the weight of the federal government behind it, the NSCI is hoping to steal a march on its rivals and break new ground in the high performance computing sphere. With all of the various challenges that the planet is facing — challenges that we’re told Exascale computing will be able to fix — it can’t come soon enough.
