Researchers in Israel have come up with an innovative hack that turns a computer’s LED light into a signaling system that shows passwords and other sensitive data.
The researchers at Ben-Gurion University of the Negev demonstrated the hack in a YouTube video posted Wednesday. It shows a hacked computer broadcasting the data through a computer’s LED light, with a drone flying nearby reading the pattern.
The researchers designed the scheme to underscore vulnerabilities of air-gapped systems, or computers that have been intentionally disconnected from the internet.
Air-gapped systems generally carry highly confidential information or operate critical infrastructure. But the researchers have been coming up with sneaky ways to extract data from these computers, like using the noise from the PC’s fan or hard drive to secretly broadcast the information to a nearby smartphone.
Their latest hack leverages the LED activity light for the hard disk drive, which can be found on many servers and desktop PCs and is used to indicate when memory is read or written.
The researchers found that with malware, they could control the LED light to emit binary signals by flashing on and off. That flickering could send out a maximum of 4,000 bits per second, or enough to leak out passwords, encryption keys and files, according to their paper. It’s likely no one would notice anything wrong.
“The hard drive LED flickers frequently, and therefore the user won’t be suspicious about changes in its activity,” said Mordechai Guri, who led the research, in a statement.
To read the signals from the LED light, all that’s needed is a camera or an optical sensor to record the patterns. The researchers found they could read the signal from 20 meters away from outside a building. With an optical zoom lens, that range could be even longer.
It wouldn’t be easy for hackers to pull off this trick. They’d have to design malware to control the LED light and then somehow place it on an air-gapped system, which typically is heavily protected.
They’d also need to find a way to read the signals from the LED light. To do so, a bad actor might hijack a security camera inside the building or fly a drone to spy through a window at night.
However, the danger of an LED light being hijacked can be easy to solve. The researchers recommend placing a piece of tape over the light, or disconnecting it from the computer.
Verizon will begin pilot testing 5G “pre-commercial services” in cities, including Atlanta, Dallas, Denver, Houston, Miami, Seattle and Washington, D.C.
The company had said last July that it laid out plans to conduct trials for its 5G network this year.
New 5G networks are expected to provide speeds at least 10 times and up to maybe 100 times faster than today’s 4G networks, with the potential to connect at least 100 billion devices with download speeds that can reach 10 gigabits per second.
AT&T Inc said in January that it planned to test its high-speed wireless 5G network for customers of its online streaming television service, DirecTv Now, in Austin, Texas.
The technology, called Perspective, will review comments and score them based on how similar they are to comments people said were “toxic” or likely to make them leave a conversation.
It has been tested on the New York Times and the companies hope to extend it to other news organizations such as The Guardian and The Economist as well as websites.
“News organizations want to encourage engagement and discussion around their content, but find that sorting through millions of comments to find those that are trolling or abusive takes a lot of money, labor, and time. As a result, many sites have shut down comments altogether,” Jared Cohen, President of Jigsaw, which is part of Alphabet, wrote in a blog post.
“But they tell us that isn’t the solution they want. We think technology can help.”
Perspective examined hundreds of thousands of comments that had been labeled as offensive by human reviewers to learn how to spot potentially abusive language.
CJ Adams, Jigsaw Product Manager, said the company was open to rolling out the technology to all platforms, including larger ones such as Facebook and Twitter where trolling can be a major headache.
The technology could in the future be expanded to trying to identify personal attacks or off-topic comments too, Cohen said.
Perspective will not decide what to do with comments it finds are potentially abusive; rather publishers will be able to flag them to their moderators or develop tools to help comment understand the impact of what they are writing.
Cohen said a significant portion of abusive comments came from people who were “just having a bad day”.
The initiative against trolls follows efforts by Google and Facebook to combat fake news stories in France, Germany and the United States after they came under fire during the U.S. presidential vote when it became clear they had inadvertently fanned false news reports.
The debate surrounding fake news has led to calls from politicians for social networks to be held more liable for the content posted on their platforms.
The Perspective technology is still in its early stages and “far from perfect”, Cohen said, adding he hoped it could be rolled out for languages other than English too.
pen source’s Mr Sweary Linus Torvalds announced the general availability of the Linux 4.10 kernel series, which includes virtual GPU (Graphics Processing Unit) support.
Linus wrote in the announcement, adding “On the whole, 4.10 didn’t end up as small as it initially looked”.
The kernel has a lot of improvements, security features, and support for the newest hardware components which makes it more than just a normal update.
Most importantly there is support for virtual GPU (Graphics Processing Unit) support, new “perf c2c” tool that can be used for analysis of cacheline contention on NUMA systems, support for the L2/L3 caches of Intel processors (Intel Cache Allocation Technology), eBPF hooks for cgroups, hybrid block polling, and better writeback management.
A new “perf sched timehist” feature has been added in Linux kernel 4.10 to provide detailed history of task scheduling, and there’s experimental writeback cache and FAILFAST support for MD RAID5.
It looks like Ubuntu 17.04 will be the first stable OS to ship with Linux 4.10.
MediaTek is planning a Helio X30 in 10nm later this year but news from Taiwan indicates that some key customers didn’t order the new flagship 10 core chip.
One of the main reasons might be the increased competition in the Chinese market and companies cannot afford to have two designs of the same phone with Qualcomm or a MediaTek chip in. The rumor is that Xiaomi, MediaTek’s big customer, might be coming up with its own Pinecone SoC and this will put some additional pressure on MediaTek’s high-end. There might be two Pinecones SoCs targeted at the mainstream and high end market.
LeEco, another big MediaTek customer is going through tough financial times, and was not interested in making big orders. Hope, which is the number one smartphone vendor in China, is usually a big customer. Another big one that usualy goes with MediaTek is the current number 3 in China, Vivo. The number two, Huawei has its own Kirin SoC while the number Four, the fruity Apple has its own SoC.
Oppo is MediaTek’s big hope as is Vivo. Oppo and Vivo are expected to sell 120 million and 100 million smartphones respectively in 2017.
The upcoming Snapdragon 835 SoC is also going to give Mediatek bother. It is shaping up to become one of the best, if not the best phone SoC of all times. MediaTek usually has a pricing advantage over most of its competitors so it might compete against it on price.
This is a TSMC manufactured chip based on the the long relationship that the company has with the biggest chip foundry which is across the street from MedaiTek’s headquarter in Hsinchu, Taiwan. The end result might be the massive cancellation of 10nm wafer orders at TSMC, as there wont be anyone who would want to buy. The timing could not be worse, as this is the first time MediaTek wanted to take the leap of faith and bet on the farm with the latest and greatest 10nm . Now it looks like it will have to cancel a lot of the 10nm orders. Still a few phones with Helio X30 deca core will hit the market.
Layoffs at computer, electronics, and telecommunications companies rose by 21 percent last year.
Beancounters at the global outplacement outfit Challenger, Gray & Christmas said that more than 96,017 US jobs were cut in 2016, compared to 79,315 the prior year.
Tech layoffs accounted for 18 percent of the total 526,915 US job cuts announced in 2016.
Of the 2016 total, some 66,821of the layoffs came from computer companies, up seven percent year over year.
Challenger attributed much of that increase to cuts made by Dell which merged with EMC. In preparation for that combination, layoffs were instituted across EMC and its constituent companies, including VMware.
But Dell was not entirely to blame Intel, IBM, Cisco, Microsoft all saw the mighty HR axeman coming down the corridors.
For example, Chipzilla’s move to axe 12,000 people or 11 percent of its workforce—was made because the company has struggled in the mobile device market.
John Challenger, chief executive of the outplacement firm added that the networking giant Cisco cut 5,500 jobs or 7 per cent of its headcount to better compete with cloud competitors like Amazon Web Services.
It does not look like things are going to get much better either. The industry is gutting itself as companies shift focus to cloud-based computing and mobile systems, Challenger warned.
MSI has unveiled yet another HTPC-friendly graphics card, the low-profile Radeon RX 460 that will comes in both 2GB and 4GB versions.
Featuring a dual-slot, low-profile, dual-fan cooler and a low-profile PCB to match, both the MSI RX 460 2GT LP and 4GT LP graphics card will be working at reference 1090MHz GPU base and 1200MHz GPU Boost clocks with GDDR5 memory working at 1750MHz on a 128-bit memory interface.
It also comes with single DVI and one HDMI display outputs.
In case you missed it, the Radeon RX 460 is based on AMD’s Polaris 11 GPU with 896 Stream Processors, 48 TMUs and 16 ROPs and should pack enough punch for a decent casual gaming experience.
Unfortunately, the price or the availability date have not been revealed but we are sure these two will appear in retail/e-tail soon at around US $100/€100.
Japan’s Toshiba Corp wished to receive at least 1 trillion yen ($8.8 billion) by selling most of its flash memory chip business, seeking to create a buffer for any fresh financial problems, a source with direct knowledge of the matter said.
The beleaguered conglomerate was pressured to abandon an initial plan to sell just under 20 percent by its main creditor banks which are worried about potential writedowns that may come on top of $6.3 billion hit to its U.S. nuclear unit, financial sources also said.
Toshiba said last week it is now prepared to sell a majority stake or even all of its chip business, the world’s biggest NAND chip producer after Samsung Electronics Co Ltd, also rocked by the emergence of fresh problems at its Westinghouse unit that have delayed the release of earnings.
The company has not decided on the size of the stake to be sold, preferring to focus on the amount that can be raised but would like to retain a one-third holding as that would give it a degree of control over the business, the source with direct knowledge said.
Its willingness to relinquish so much of the unit underscores not only the depths of its financial woes but also resignation on the part of management to becoming a much smaller company.
The sale “is the best and the only way Toshiba can raise a large amount of funds and wipe out concerns about its credit risk,” said the source, adding that the sale should be completed by the end of March next year.
It wants to restart the sale process as soon as possible and may sell to multiple buyers rather than one bidder with interest already received from investment funds, other chipmakers and client companies, he also said.
A separate person with knowledge of the matter said Toshiba will outline terms of the sale by the end of February, conduct a first round of bids in March and aim to have chosen a preferred bidder or bidders by the end of May. The person also said Toshiba valued the chips business at around 1.5 trillion yen.
A Toshiba spokeswoman said the company cannot comment on the specifics of the sale process. Sources declined to be identified as they were not authorized to speak to the media.
European Union data protection watchdogs are indicating they are still concerned about the privacy settings of Microsoft’s Windows 10 operating system despite the U.S. company announcing changes to the installation process.
The watchdogs, a group made up of the EU’s 28 authorities responsible for enforcing data protection law, wrote to Microsoft last year expressing concerns about the default installation settings of Windows 10 and users’ apparent lack of control over the company’s processing of their data.
The group – referred to as the Article 29 Working Party -asked for more explanation of Microsoft’s processing of personal data for various purposes, including advertising.
“In light of the above, which are separate to the results of ongoing inquiries at a national level, even considering the proposed changes to Windows 10, the Working Party remains concerned about the level of protection of users’ personal data,” the group said in a statement which also acknowledged Microsoft’s willingness to cooperate.
Microsoft was not immediately available to comment.
A number of national authorities have already begun enquiries into Windows 10, including France which in July ordered Microsoft to stop collecting excessive user data.
The EU privacy group said that despite a new installation screen presenting users with five options to limit or switch off Microsoft’s processing of their data, it was not clear to what extent users would be informed about the specific data being collected.
Microsoft uses data collected through Windows 10 for different purposes, including advertising, the group said in its statement said.
“Microsoft should clearly explain what kinds of personal data are processed for what purposes. Without such information, consent cannot be informed, and therefore, not valid.”
A patent war is being fought between two of the industry smartphone leaders of yesteryear – Nokia and Blackberry.
Blackberry filed a patent-infringement lawsuit against Nokia Oyj, demanding royalties on the Finnish company’s mobile network products that use an industry wide technology standard.
Blackberry moaned that Nokia’s Flexi Multiradio base stations, radio network controllers and Liquid Radio software are using technology covered by as many as 11 patents owned by BlackBerry.
It added that Nokia was encouraging the use” of the standard- compliant products without a license from Blackberry.
Blackberry did not say how much it wanted Nokia to cough up, but it would appear to be part of Chief Executive Officer John Chen is working to find new ways to pull revenue out of Blackberry’s technology.
He’s used acquisitions to add a suite of software products and negotiated licensing agreements to take advantage of the company’s thick book of wireless technology patents.
Nokia is aware of the inventions because the company has cited some of the patents in some of its own patent applications, BlackBerry said.
Some of the patents were owned by Nortel and Nokia had at one point tried to buy them as part of a failed bid for Nortel’s business in 2009, according to Blackberry.
BlackBerry was part of a group called Rockstar Consortium that bought Nortel’s patents out of bankruptcy for $4.5 billion in 2011. The patents were split up between the members of the group, which included Apple and Microsoft.
Since Blackberry contends that patents cover essential elements of a mobile telecommunications standard known as 3GPP, it has pledged to license them on fair and reasonable terms.
China’s Alibaba Group Holding Ltd announced that it has formed a strategic partnership with Bailian Group, the largest retailer by store numbers to join the e-commerce giant’s drive to use big data to improve and profit from brick-and-mortar sales.
The deal, which does not include any financial investment in Bailian, is the latest in Alibaba’s still nascent efforts to capture a bigger share of the retail market as online sales growth slows.
It has also spent $4.6 billion on a minority stake in appliances retailer Suning Commerce Group Co Ltd, is leading a $2.6 billion bid to take department store and shopping mall operator Intime Retail Group Co Ltd private and has bought a stake in grocery chain Sanjiang Shopping Club Co Ltd.
News of the agreement sent shares in Bailian Group firms surging but analysts cautioned it may take several years before returns from using big data can make a significant difference to earnings.
“There is a big push right now across brands to try and figure out how to mix physical and online shopping but gains so far have been limited,” said Shanghai-based retail analyst Ben Cavender at China Market Research Group.
The two firms will initially cooperate on supply chain technology using Alibaba’s big data capabilities and will integrate Alipay payments with Bailian Group’s existing membership program.
Bailian operates 4,700 outlets in 200 cities including supermarkets, convenience stores and pharmacies – more than double the stores owned by Suning, Intime and Sanjiang combined.
An Alibaba spokesman declined to comment on how many stores will be involved in the new partnership. A Bailian spokesman did not respond to a request for comment.
Alibaba, which has an active user base of around 500 million, has said it wants to tap China’s entire $4.8 trillion retail economy by developing data-driven management tools for retailers and brands.
China’s e-commerce market is expected to average around 18 percent annually until 2020, according to consultancy Bain & Company, compared with an average rate of 35 percent during the preceding four years.
And while e-commerce has seen phenomenal growth in China, brick-and-mortar sales still accounted for 84 percent of total retail sales in China last year, Bain said.
Among Bailian Group firms, shares in Shanghai Bailian Group Co Ltd were up by the 10 percent daily limit in afternoon trade. Lianhua Supermarket Holdings Co Ltd rose 7 percent and Shanghai Material Trading Co Ltd climbed 5 percent.
Snap Inc hit the roads of London on Monday promoting its initial public offering with a daring proposition: that it can build hot-selling hardware gadgets and ad-friendly software features fast enough to stay one step ahead of Facebook.
No longer just a purveyor of a smartphone app for disappearing messages, Snap has hired hundreds of hardware engineers, built a secretive product development lab and scoured the landscape for acquisitions as it pursues its newly stated ambition to be “a camera company.”
These efforts, which are aimed at developing hardware and so-called augmented reality technologies, are central to the strategy of a company that is seeking a valuation of up to $22 billion in its early March IPO despite heavy losses and the specter of stiff competition for advertising dollars with a far-larger Facebook.
It is a big gamble and the odds against Snap are long.
There is little precedent for a company with its roots in software and social networking succeeding in the notoriously difficult consumer hardware business. Few U.S. firms aside from Apple have made big profits on hardware, and camera and wearable gadget makers have much lower valuations than Snap is seeking. Once-hot camera start-up GoPro is a cautionary tale: its stock sits 61 percent below its 2014 IPO price.
More broadly, creating new products and features that have mass-market appeal and cannot be readily mimicked is a huge challenge, analysts say.
“It’s worrisome,” said Paul Meeks, chief investment officer at Sloy, Dahl & Holst, which manages more than $1 billion in assets. “Snapchat is going to have to continue to be really innovative and distinctive. It’s going to be very tough to trump Facebook.”
Snap declined to comment for this story.
Snap first signaled its new focus with the September reveal of Spectacles, funky sunglasses with an embedded video camera for posting to the Snapchat app. The company spent $184 million on research and development last year, nearly half its revenue.
General Motors Co plans to add thousands of self-driving electric cars in a series of test fleets in partnership with ride-sharing affiliate Lyft Inc, beginning in 2018, two sources familiar with the automaker’s plans said this week.
It is expected to be the largest such test of fully autonomous vehicles by any major automaker before 2020, when several companies have said they plan to begin building and deploying such vehicles in higher volumes. Alphabet Inc’s Waymo subsidiary, in comparison, is currently testing about 60 self-driving prototypes in four states.
Most of the specially equipped versions of the Chevrolet Bolt electric vehicle will be used by San Francisco-based Lyft, which will test them in its ride-sharing fleet in several states, one of the sources said. GM has no immediate plans to sell the Bolt AV to individual customers, according to the source.
The sources spoke only on condition of anonymity because GM has not announced its plans yet.
GM executives have said in interviews and investor presentations during the past year they intend to mass-produce autonomous vehicles and deploy them in ride services fleets. However, GM officials have not revealed details of the scale of production, or the timing of the deployment of those vehicles.
In a statement on Friday, GM said: “We do not provide specific details on potential future products or technology rollout plans. We have said that our AV technology will appear in an on-demand ride sharing network application sooner than you might think.”
Lyft declined to comment.
The fatal clock timing flaw that causes switches, routers and security appliances die after about 18 months of service is apparently a feature of some Juniper products.
Cisco was the first vendor to post a notice about the problem earlier this month saying the notice covers some of the company’s most widely deployed products, such as certain models of its Series 4000 Integrated Services Routers, Nexus 9000 Series switches, ASA security devices and Meraki Cloud Managed Switches.
Juniper is telling its customers something similar:
“Although we believe the Juniper products with this component are performing normally as of February 13, 2017, the [listed] Juniper products could after the product has been in operation for at least 18 months begin to exhibit symptoms such as the inability to boot, or cease to operate. Recovery in the field is not possible. Juniper product with this supplier’s component were first placed into service on January 2016. Jupiter is working with the component supplier to implement a remediation. In addition, Juniper’s spare parts depots will be purged and updated with remediated products.”
The products in the warning comprise 13 Juniper switches, routers and other products including the MPC7E 10G, MPC7E (multi rate), MX2K-MPC8E, EX 920 Ethernet switches and PTX3000 integrated photonic line card.
So far neither Cisco nor Juniper have blamed Intel for the fault. However, Chipzilla did describe a flaw on its Atom C2000 chip which is under the bonnet of shedloads of net gear.
Intel said that problems with its Atom chip will hurt Intel’s 2016 Q4 earnings. CFO Robert Swan said that Intel was seeing a product quality issue in the fourth quarter with slightly higher expected failure rates under certain use and time constraints.
Swan said that it will be fixed with a minor design fix that Intel was working with its clients to resolve.
Intel had hoped it would see the back of its short-lived low-power Atom chips for servers. They were used in micro servers but also networking equipment from companies.
HPE and Dell are keeping quiet about the clock technology, though both are rumoured to use it. They might be hoping that Intel will come up with a fix so they can pretend it never happened.
Announced officially by AMD and to be held on February 28th at Ruby Skye in San Francisco, the new Capsaicin and Cream event promises “a feature-packed show highlighting the hottest new graphics and VR technologies propelling the games industry forward”.
Streamed live, the event will include the main Capsaicin & Cream part, which will hopefully include a bit more details on the actual lineup of graphics cards based on the new Vega GPU, as well as the Cream developer sessions which promise “inspiring talks focused on rendering ideas and new paths forward, driven by game industry gurus from multiple companies including Epic and Unity”.
The event will start at 10:00 AM PST, while the livestream is scheduled to start at 10:30 AM PST (20:00 CET).
