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.

AMD’s Vegas GPU Details Spotted

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.

Is nVidia Going Linux

Comments Off on Is nVidia Going Linux

The dark satanic rumor mill has manufactured a hell on earth yarn claiming that Nvidia is working on its own Linux OS for gamers.

A slide has tipped up showing a screen capture of an installer screen for this operating system supposedly going by the “NLINUX” codename at NVIDIA.

Not much to go on, but it does appear that Nvidia is looking at creating a distribution for gamers similar to that operated by Valve.

It is hard to see what Nvidia would get out of it. Nvidia also has its SHIELD TV that’s powered by Tegra hardware and offers a variety of games over their cloud/streaming “GeForce NOW” service.

So why would Nvidia need a full-blown Linux distribution? The only place it could use one is on the desktop, but that would just mean bringing another Linux distribution into a crowded market with little return for its efforts.

Nvidia already has control of the Linux gaming systems and its cards do better on Linux than AMDs so an “optimized” Linux OS is not going to sell them more graphics cards for Linux gamers. It would have to add something which is better than Steam, or Ubuntu and what could that be?

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.

Is HP’s Forthcoming Split A Good Idea?

Comments Off on Is HP’s Forthcoming Split A Good Idea?

HP Has released its financial results for the third quarter and they make for somewhat grim reading.

The company has seen drops in key parts of the business and an overall drop in GAAP net revenue of eight percent year on year to $25.3bn, compared with $27.6bn in 2014.

The company failed to meet its projected net earnings per share, which it had put at $0.50-$0.52, with an actual figure of $0.47.

The figures reflect a time of deep uncertainty at the company as it moves ever closer to its demerger into HP and Hewlett Packard Enterprise. The latter began filing registration documents in July to assert its existence as a separate entity, while the boards of both companies were announced two weeks ago.

Dell CEO Michael Dell slammed the move in an exclusive interview with The INQUIRER, saying he would never do the same to his company.

The big boss at HP remained upbeat, despite the drop in dividend against expectations. “HP delivered results in the third quarter that reflect very strong performance in our Enterprise Group and substantial progress in turning around Enterprise Services,” said Meg Whitman, chairman, president and chief executive of HP.

“I am very pleased that we have continued to deliver the results we said we would, while remaining on track to execute one of the largest and most complex separations ever undertaken.”

To which we have to ask: “Which figures were you looking at, lady?”

Breaking down the figures by business unit, Personal Systems revenue was down 13 percent year on year, while notebook sales fell three percent and desktops 20 percent.

Printing was down nine percent, but with a 17.8 percent operating margin. HP has been looking at initiatives to create loyalty among print users such as ink subscriptions.

The Enterprise Group, soon to be spun off, was up two percent year on year, but Business Critical system revenue dropped by 21 percent, cancelled out by networking revenue which climbed 22 percent.

Enterprise Services revenue dropped 11 percent with a six percent margin, while software dropped six percent with a 20.6 percent margin. Software-as-a-service revenue dropped by four percent.

HP Financial Services was down six percent, despite a two percent decrease in net portfolio assets and a two percent decrease in financing volume.

Is Oracle Sliding?

Comments Off on Is Oracle Sliding?

Oracle said weak sales of its traditional database software licenses were made worse by a strong US dollar lowered the value of foreign revenue.

Shares of Oracle, often seen as a barometer for the technology sector, fell 6 percent to $42.15 in extended trading after the company’s earnings report on Wednesday.

Shares of Microsoft and Salesforce.com, two of Oracle’s closest rivals, were close to unchanged.

Daniel Ives, an analyst at FBR Capital Markets said that this announcement speaks to the headwinds Oracle is seeing in the field as their legacy database business is seeing slowing growth.

It also shows that while Cloud business has seen pockets of strength it is not doing as well as many thought,

Oracle, like other established tech companies, is looking to move its business to the cloud-computing model, essentially providing services remotely via data centres rather than selling installed software.

The 38-year-old company has had some success with the cloud model, but is not moving fast enough to make up for declines in its traditional software sales.

Oracle, along with German rival SAP has been losing market share in customer relationship management software in recent years to Salesforce.com, which only offers cloud-based services.

Because of lower software sales and the strong dollar, Oracle’s net income fell to $2.76 billion, or 62 cents per share, in the fourth quarter ended May 31, from $3.65 billion, or 80 cents per share, a year earlier.

Revenue fell 5.4 percent to $10.71 billion. Revenue rose 3 percent on a constant currency basis. Analysts had expected revenue of $10.92 billion, on average.

Sales from Oracle’s cloud-computing software and platform service, an area keenly watched by investors, rose 29 percent to $416 million.

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.
