PC Monitors Vulnerable To Hacking

Comments Off on PC Monitors Vulnerable To Hacking

You should probably be leery of what you see since, apparently, your computer monitor can be hacked.

Researchers at DEF CON presented a way to manipulate the tiny pixels found on a computer display.

Ang Cui and Jatin Kataria of Red Balloon Security were curious how Dell monitors worked and ended up reverse-engineering one.

They picked apart a Dell U2410 monitor and found that the display controller inside can be used to change and log the pixels across the screen.

During their DEF CON presentation, they showed how the hacked monitor could seemingly alter the details on a web page. In one example, they changed a PayPal’s account balance from $0 to $1 million, when in reality the pixels on the monitor had simply been reconfigured.

It wasn’t exactly an easy hack to pull off. To discover the vulnerability, both Cui and Kataria spent their spare time over two years, conducting research and understanding the technology inside the Dell monitor.

However, they also looked at monitors from other brands, including Samsung, Acer and Hewlett Packard, and noticed that it was theoretically possible to hack them in the same manner as well.

The key problem lies in the monitors’ firmware, or the software embedded inside. “There’s no security in the way they update their firmware, and it’s very open,” said Cui, who is also CEO of Red Balloon.

The exploit requires gaining access to the monitor itself, through the HDMI or USB port. Once done, the hack could potentially open the door for other malicious attacks, including ransomware.

For instance, cyber criminals could emblazon a permanent message on the display, and ask for payment to remove it, Kataria said. Or they could even spy on users’ monitors, by logging the pixels generated.

However, the two researchers said they made their presentation to raise awareness about computer monitor security. They’ve posted the code to their research online.

“Is monitor security important? I think it is,” Cui said.

Dell couldn’t be reached for immediate comment.

Comments Off on AMD Goes 16 Core Snowy Owl

Naples is a 32 Zen core Opteron with 64 threads. The 16 core Zen version with a BGA socket is codenamed Snowy Owl. AMD thinks that Snowy Owl will be a great match for the communication and network markets that needs a high performance 64-bit X86 CPU.

Snowy Owl has 16 cores and 32 threads, all based on 14nm FinFET Zen transistors. The processor supports up to 32MB of shared L3 cache. We also mentioned a processor cluster codenamed Zeppelin. This seems to be the key to the Zen architecture as more Zeppelin clusters are creating more core Opterons.

Each Zeppelin has eight Zen cores and each Zen core has 512KB dedicated L2 cache memory. Four Zen cores share 8MB of L3 memory making the total L3 cache size  16MB.  Zeppelin (ZP) comes with PCIe Gen 3, SATA 3, 10GbE, sever controller Hub, AMD secure processor as well as the DDR4 Memory controller. AMD is using a super-fast coherent interconnect to create more than one Zeppelin core.

One Zeppelin cluster would make an 8 core, 16 thread CPU with 4MB L2 and 16MB L3 cache and in our case product codenamed Snowy owl has 16 cores, 32 threads 8MB of L2 (512KB x 16) and 32MB L3 (4x8MB).

The Snowy Owl with 16 cores uses a SP4 Multi Chip Module (MCM) BGA socket, while the Naples uses MCM based SP3. These two are not pin compatible but 16 and 8 core Zen based Opterons will fit in the same socket.

Snowy Owl has four independent memory channels and up to 64 lanes of PCIe Gen3. When it comes to storage, it supports up to 16 SATA or NVME storage channels and 8x10GbE for some super-fast networking solutions.

As you see, there will be plenty of Zen based Opteron possibilities and most of them will start showing up by mid-2017.  The TDP Range for Snowy Owl is sub 100W and capable of sinking the TDP down to 35W. Yes, we do mean that there may well be a quad core Zen Opteron too.

AMD Goes After Intel’s Skylake With Bristol Ridge

Comments Off on AMD Goes After Intel’s Skylake With Bristol Ridge

AMD has revealed the firm’s seventh-generation system-on-a-chip accelerated processing units (APUs).

Bristol Ridge and Stoney Ridge sound a little like locations in a Somerset version of Game of Thrones, but they both feature AMD’s Excavator x86 processor cores and Radeon R7 graphics, which AMD sees powering e-sports gaming on laptops.

Bristol Ridge is the more powerful of the two coming in 35W and 15W versions of AMD FX, A12 and A10 processors, offering up to 3.7GHz of processing power. The former two processors are paired with up to eight Graphics Core Next (GCN) cores in the R7 to provide a decent pool of graphics processing power.

Stoney Bridge offers less in the way of processor power, topping out at 3.5GHz, and versions include 15W A9, A6 and E2 processor configurations coupled with lower powered graphics accelerators.

AMD claimed that the new APUs offer a 50 per cent hike in performance over the previous generation Carrizo APUs. However, this rise is over APUs from the early part of Carrizo’s lifecycle, so performance gains over the most recent Carrizo APUs are likely to be 10 to 20 per cent.

AMD also said that its silicon is faster than rival chips from Intel, including the i3-6100U found in several ultraportable laptops.

Many of these tests are subjective and depend on how a hardware manufacture configures and sets up the APUs in a laptop or tablet, but AMD does have its graphics tech to draw on, such as the GCN architecture, which could give it the edge over Intel’s chips when it comes to pushing pixels.

The APUs will be aimed primarily at slim laptops that need low-power consumption chips, much like Intel’s Skylake line.

Bristol Ridge is currently available to end users only in the form of HP’s latest Envy laptop. But now that AMD has debuted the full range of the seventh-generation APUs we can expect to see them in other ultraportable machines before too long.

Is nVidia Taking Qualcomm To Court?

Comments Off on Is nVidia Taking Qualcomm To Court?

Nvidia has dragged Qualcomm into court for allegedly crushing a $352 million chipset deal.

Nvidia claims it was forced to wind down its cellular mobile broadband chipset business, including its Icera unit just four years after buying it, because of Qualcomm’s anti-trust antics.

Qualcomm’s alleged tactics led to “unexplained delays in customer orders, reductions in demand volumes and contracts never being entered into, even after a customer or mobile network cooperating with a prospective customer has agreed or expressed a strong intention to purchase” Nvidia’s chipsets, the company moaned.

The claim for cash comes as European Union regulators step up antitrust investigations into Qualcomm sales tactics that officials said thwarted other designers of mobile-phone chip technology. This could result in fines or an EU order forcing a company to change its behaviour.

The EU thinks Qualcomm may have charged below-cost fees for chips used in mobile Internet modems known as dongles from 2009 to 2011 to thwart smaller competitor Icera. Regulators are separately probing what they say are exclusivity payments Qualcomm paid to a phone and tablet manufacturer for using its designs.

Qualcomm is “confident” it would prevail in both the EU investigation and the lawsuit.

Nvidia is seeking a declaration from the judge that Qualcomm’s conduct was an abuse of a dominant position, compensation, and an account of the profits it says Qualcomm gained from unlawful conduct, according to the court filings.

Comments Off on AMD’s Vegas GPU Details Spotted

Details of AMD’s Vega GPU were leaked and then taken down from AMD R&D Manager’s LinkedIn profile page over Easter.

Hexus spotted Yu Zheng, an R&D Manager at AMD Shanghai had listed the work on Project Greenland as a work experience highlight on his LinkedIn profile page. Greenland is described as “A leading chip of the first graphics IP v9.0 generation, it has full capacity of 4096 shader processor along with whole new SOC v15 architecture.”

The Graphics IP v9.0 designation is thought to signify a Vega GPU in the making. Zheng mentions this is an SOC, but then Hawaii and Fiji chips were described the same. Fiji is part of the graphics IP v8.0 family, as will be Polaris.

Vega following after Polaris, and designated as a ‘HMB2′ GPU by AMD, it looks like Vega based graphics cards will be the successors to the HBM equipped Fiji range such as the Radeon Fury and Nano. Fiju can manage 4096 stream processors,  but with an upgrade to HBM2, 14nm process and other optimisation it is estimated that a Greenland/Vega GPU based graphics cards will offer 20 to 30 per cent better performance.

So with Greenland/Vega sporting HBM2 memory Hexus thinks that Polaris packing graphics cards will therefore feature GDDR5/X memory.

Comments Off on Seagate Goes 8TB For Surveillance

Seagate has become the first hard drive company to create an 8TB unit aimed specifically at the surveillance market, targeting system integrators, end users and system installers.

The Seagate Surveillance HDD, as those wags in marketing have named it, is the highest capacity of any specialist drive for security camera set-ups, and Seagate cites its main selling points as maximizing uptime while removing the need for excess support.

“Seagate has worked closely with the top surveillance manufacturers to evolve the features of our Surveillance HDD products and deliver a customized solution that has precisely matched market needs in this evolving space for the last 10 years,” said Matt Rutledge, Seagate’s senior vice president for client storage.

“With HD recordings now standard for surveillance applications, Seagate’s Surveillance HDD product line has been designed to support these extreme workloads with ease and is capable of a 180TB/year workload, three times that of a standard desktop drive.

“It also includes surveillance-optimized firmware to support up to 64 cameras and is the only product in the industry that can support surveillance solutions, from single-bay DVRs to large multi-bay NVR systems.”

The 3.5in drive is designed to run 24/7 and is able to capture 800 hours of high-definition video from up to 64 cameras simultaneously, making it ideal for shopping centers, urban areas, industrial complexes and anywhere else you need to feel simultaneously safe and violated. Its capacity will allow 6PB in a 42U rack.

Included in the deal is the Seagate Rescue Service, capable of restoring lost data in two weeks if circumstances permit, and sold with end users in mind for whom an IT support infrastructure is either non-existent or off-site. The service has a 90 percent success rate and is available as part of the drive cost for the first three years.

Seagate demonstrated the drive today at the China Public Security Expo. Where better than the home of civil liberty infringement to show off the new drive?

Earlier this year, Seagate announced a new co-venture with SSD manufacturer Micron, which will come as a huge relief after the recent merger announcement between WD and SanDisk.

Can IBM Beat Moore’s Law?

Comments Off on Can IBM Beat Moore’s Law?

 

Big Blue Researchers have discovered a way to replace silicon semiconductors with carbon nanotube transistors and think that the development will push the industry past Moore’s law limits.

IBM said its researchers successfully shrunk transistor contacts in a way that didn’t limit the power of carbon nanotube devices. The chips could be smaller and faster and significantly surpass what’s possible with today’s silicon semiconductors.

The chips are made from carbon nanotubes consist of single atomic sheets of carbon in rolled-up tubes. This means that high-performance computers may well be capable of analysing big data faster, and battery life and the power of mobile and connected devices will be better. The advance may enable cloud-based data centres to provide more efficient services, IBM claims.

Moore’s law, which has for years governed the ability of the semiconductor industry to double the processing power of chips every 24 months is starting to reach the limits of physics when it comes to doubling the power of silicon chips. This could mean a slowing of significant computing performance boosts unless someone comes up with something fast.

IBM researchers claim to have proved that carbon nanotube transistors can work as switches at widths of 10,000 times thinner than a human hair, and less than half the size of the most advanced silicon technology.

The latest research has overcome “the other major hurdle in incorporating carbon nanotubes into semiconductor devices which could result in smaller chips with greater performance and lower power consumption,” IBM said.

Electrons found in carbon transistors move more efficiently than those that are silicon-based, even as the extremely thin bodies of carbon nanotubes offer more advantages at the atomic scale, IBM says.

The new research is jump-starting the move to a post-silicon future, and paying off on $3 billion in chip research and development investment IBM announced in 2014.

Comments Off on Can The IdeaPad Challenge The Surface Pro?

Lenovo has unveiled it’s updated IdeaPad and IdeaCentre devices aimed at those looking to upgrade to Windows 10 systems, including a Skylake-powered Surface competitor.

Lenovo’s new line-up includes seven computers, comprising the IdeaCentre AIO 700 desktop PC, the IdeaPad Miix 700a 2-in-1 tablet hybrid, and five laptops: the IdeaPad 300 and 500 and their lighter cousins, the IdeaPad 100S, 300S and 500S.

Lenovo said that the new designs feature an option for Intel’s RealSense 3D cameras alongside Windows 10 for “never-before-seen PC performance” while “giving discerning shoppers multiple reasons to upgrade this holiday season”.

The Lenovo IdeaPad Miix 700 (above) sees the firm setting its sights squarely on Microsoft’s Surface, with the device sporting an integrated kickstand, optional keyboard cover and the same dual watchband hinges as seen on on the Yoga 3 Pro.

It also boasts a 12 inch Full HD+ 2160×1440 display, a 6th-generation Intel Core processor, up to 8GB of RAM, up to 256GB SSD and either Windows 10 Pro or Windows 10 Home.

The IdeaPad MIIX 700 starts at $699, and will be available sometime this year.

The Lenovo IdeaCentre AIO 700 desktop (below) is said to deliver up to double the power, screen resolution and memory capacity of the previous-generation, making it ideal for videos and gaming, Lenovo said.

The desktop has the latest Intel Core i7 processor, coupled with up to a 27in UHD 10-point multitouch display alongside JBL stereo speakers and discrete graphics.

“This all-in-one desktop is upgraded to up to twice the CPU performance, screen resolution and memory capacity of its three-year-old previous generation, offering music and movie buffs double the incentive to refresh their hardware this season,” the firm said.

There’s also a removable slip-off back panel providing flexibility for those wanting to upgrade or maintain the system. The IdeaCentre AIO 700 24in desktop starts at $1,099 and will be available in October.

Meanwhile, the new Lenovo IdeaPad 300 and 500 laptops are claimed to be 33 percent thinner than the same range three years ago. This doesn’t sound like much of a feat, but Lenovo promised that the devices will “take portability to the next level”, weighing 2.1kg for the 14in laptop and 2.3kg for the 15in.

They come with up to Nvidia GeForce 920 graphics, 1TB of storage and Dolby Advanced Audio. The IdeaPad 500 will be powered by the latest Intel 6th generation Core i7 processor with optional JBL speakers.

For those who want an even thinner and lighter laptop, the IdeaPad 100S, 300S and 500S are thinner and lighter than their IdeaPad 300 and 500 cousins, and much lighter than their comparably priced counterparts from three years ago. The IdeaPad 100S 14in laptop is 35 percent lighter, while the IdeaPad 500S 15in laptop is 20 percent lighter.

The IdeaPad laptop range will start from $179, going up to $499 depending on model, size and specifications, and will be available in October.

Did Microsoft Intentionally Delay The Surface Pro 4?

Comments Off on Did Microsoft Intentionally Delay The Surface Pro 4?

The latest rumors suggest that Microsoft was waiting to jack the latest Intel Skylake processor under its bonnet.

Redmond seemingly wants the new Surface Pro to be state of the art and be a tablet which is useful. Skylake will give it better battery life and performance with current industry standards like Bluetooth 4.1, Cat6 LTE, WiDi 6.0, and A4WP wireless charging weaved into it.

Intel will support the tablets through compatibility with 3D cameras and audio processing software plus better stylus interaction.

There is no sign of confirmation of the rumors. Microsoft has been quiet so far about the Surface Pro 4. We had been expecting it to highlight some of the better features of Windows 10.

However if the rumors are true it will be a hell of a lot better than the MacBook Air 2015 because it will feature innovation, rather than just being thin.

Latest news about its release date suggests a 2016 launch.

Comments Off on Russia Banking On Home Grown CPUs

A Russian firm announced its intention to build its own homegrown CPUs as part of a cunning plan to keep the Americans from spying on the glorious Empire of Tsar Putin and oil oligarchs.

Moscow Centre of SPARC Technologies (MCST) has announced it’s now taking orders for its Russian-made microprocessors from domestic computer and server manufacturers.

Dubbed the Elbrus-4C, it was fully designed and developed in MCST’s Moscow labs. It’s claimed to be the most high-tech processor ever built in Russia. They claim it is comparable with Intel’s Core i3 and Intel Core i5 processors, although they do not say what generation as one spec we found claimed it could manage a blistering 1.3 GHz which is slightly less than an average mobile phone.

MCST unveiled a new PC, the Elbrus ARM-401 which is powered by the Elbrus-4C chip and runs its own Linux-based Elbrus operating system. MCST claimed it can run Windows and Linux distributions. Yhe company has built a data centre server rack, the Elbrus-4.4, which is powered by four Elbrus-4C microprocessors and supports up to 384GB of RAM.

MCST said the Elbrus-4.4 is suitable for web servers, database servers, storage systems, servers, remote desktops and high-performance clusters.

Sergei Viljanen, editor in chief of the Russian-language PCWorld website said that the chip was at least five years behind the west.

“Russian processor technology is still about five years behind the west. Intel’s chips come with a 14nm design, whereas the Elbrus is 65 nm, which means they have a much higher energy consumption.”

MCST’s Elbrus-4C chips are powered by a 4-core processors, and come with an interface for hard drives and other peripherals. The company finalized development of Elbrus-4C in April 2014, and began mass production last autumn.
