Graphene May Give Processors A Boost

Comments Off on Graphene May Give Processors A Boost

Researchers at MIT have figured out that graphene, sheets of atom-thick carbon, could be used to make chips a million times faster.

The researchers have worked out that slowing the speed of light to the extent that it moves slower than flowing electrons can create an “optical boom”, the optical equivalent of a sonic boom.

Slowing the speed of light is no mean feat, but the clever folks at MIT managed it by using the honeycomb shape of carbon to slow photons to slow photons to several hundredths of their normal speed in a free space, explained researcher Ido Kaminer.

Meanwhile, the characteristics of graphene speed up electrons to a million metres a second, or around 1/300 of the speed of light in a vacuum.

The optical boom is caused when the electrons passing though the graphene reach the speed of light, effectively breaking its barrier in the carbon honeycomb and causing a shockwave of light.

As electrons move faster than the trapped light, they bleed plasmons, a form of virtual particle that represents the oscillation of electrons on the graphene’s surface.

Effectively, it is the equivalent of turning electricity into light. This is nothing new – Thomas Edison did it a century ago with fluorescent tubes – but it can efficiently and controllably generate plasmons at a scale that works with microchip technology.

The discovery could allow chip components to be made from graphene to enable the creation of light-based circuits. These circuits could be the next step in the evolution of chip and computing technology, as the transfer of data through light is far faster than using electrons in today’s chips, even the fast pixel-pushing ones.

So much faster that it’s “six orders of magnitude higher than what is used in electronics”, according to Kaminer. That’s up to a million times faster in plain English.

“There’s a lot of excitement about graphene because it could be easily integrated with other electronics,” said physics professor Marin Soljačić, a researcher on the project, who is confident that MIT can turn this theoretical experiment into a working system. “I have confidence that it should be doable within one to two years.”

This is a pretty big concept and almost sci-fi stuff, but we’re always keen to see smaller and faster chips. It also shows that the future tech envisioned by the world of sci-fi may not be that far away.

Symantec Has Some Flaws With SEP

Comments Off on Symantec Has Some Flaws With SEP

Symantec has warned of three serious vulnerabilities in its Endpoint Protection (SEP) software, and is advising users to update their systems.

The bugs affect all builds of the 12.1 version of the SEP software, with the first two flaws allowing authorised but low privilege users of the software to gain elevated and administrative access to the management console, which can be accessed either locally or through a web-based portal.

The third bug is in the sysplant driver and enables users to bypass the SEP’s security controls and run malware and other malicious code on a targeted client machines.

“Exploitation attempts of this type generally use known methods of trust exploitation requiring enticing a currently authenticated user to access a malicious link or open a malicious document in a context such as a website or in an email,” said the security firm.

There have been no recorded exploits of the flaws, so it would appear that Symantec has squashed the bugs before they became a real-world problem for its customers.

The first two bugs were discovered by security researcher Anatoly Katyushin from rival firm Kaspersky Labs, which is a little embarrassing. Discovery of the third bug was credited to the enSilo Research Team.

Symantec advises SEP users to update their software to the 12.1 RU6 MP4 version. It also recommends that users should take precautions and restrict remote access to the management console in order to prevent hackers from attacking client systems through the web portal.

While hackers can direct sophisticated malware at even the most robustly secured systems, exploiting flaws in software offers an easier route into machines and networks, providing hackers get in before the bugs are discovered and patched.

Recent examples can be seen with the discovery of iOS malware which threatens iPhones through an Apple DRM flaw, and an error on Code.org’s website which saw the emails of its volunteers exposed.

Is Microsoft A Risk?

Comments Off on Is Microsoft A Risk?

Hewlett Packard Enterprise (HPE) has cast a shade on what it believes to be the biggest risks facing enterprises, and included on that list is Microsoft.

We ain’t surprised, but it is quite a shocking and naked fact when you consider it. The naming and resulting shaming happens in the HPE Cyber Risk Report 2016, which HPE said “identifies the top security threats plaguing enterprises”.

Enterprises, it seems, have myriad problems, of which Microsoft is just one.

“In 2015, we saw attackers infiltrate networks at an alarming rate, leading to some of the largest data breaches to date, but now is not the time to take the foot off the gas and put the enterprise on lockdown,” said Sue Barsamian, senior vice president and general manager for security products at HPE.

“We must learn from these incidents, understand and monitor the risk environment, and build security into the fabric of the organisation to better mitigate known and unknown threats, which will enable companies to fearlessly innovate and accelerate business growth.”

Microsoft earned its place in the enterprise nightmare probably because of its ubiquity. Applications, malware and vulnerabilities are a real problem, and it is Windows that provides the platform for this havoc.

“Software vulnerability exploitation continues to be a primary vector for attack, with mobile exploits gaining traction. Similar to 2014, the top 10 vulnerabilities exploited in 2015 were more than one-year-old, with 68 percent being three years old or more,” explained the report.

“In 2015, Microsoft Windows represented the most targeted software platform, with 42 percent of the top 20 discovered exploits directed at Microsoft platforms and applications.”

It is not all bad news for Redmond, as the Google-operated Android is also put forward as a professional pain in the butt. So is iOS, before Apple users get any ideas.

“Malware has evolved from being simply disruptive to a revenue-generating activity for attackers. While the overall number of newly discovered malware samples declined 3.6 percent year over year, the attack targets shifted notably in line with evolving enterprise trends and focused heavily on monetisation,” added the firm.

“As the number of connected mobile devices expands, malware is diversifying to target the most popular mobile operating platforms. The number of Android threats, malware and potentially unwanted applications have grown to more than 10,000 new threats discovered daily, reaching a total year-over-year increase of 153 percent.

“Apple iOS represented the greatest growth rate with a malware sample increase of more than 230 percent.”

Will Facebook Go Open-Source

Comments Off on Will Facebook Go Open-Source

Facebook has unveiled its next-generation GPU-based systems for training neural networks, Open Rack-compatible hardware code-named “Big Sur” which it plans to open source.

The social media giant’s latest machine learning system has been designed for artificial intelligence (AI) computing at a large scale, and in most part has been crafted with Nvidia hardware.

Big Sur comprises eight high-performance GPUs of up to 300 watts each, with the flexibility to configure between multiple PCI-e topologies. It makes use of Nvidia’s Tesla Accelerated Computing Platform, and as a result is twice as fast as Facebook’s previous generation rack.

“This means we can train twice as fast and explore networks twice as large,” said the firm in its engineering blog. “And distributing training across eight GPUs allows us to scale the size and speed of our networks by another factor of two.”

Facebook claims that as well as better performance, Big Sur is also far more versatile and efficient than the off-the-shelf solutions in its previous generation.

“While many high-performance computing systems require special cooling and other unique infrastructure to operate, we have optimised these new servers for thermal and power efficiency, allowing us to operate them even in our own free-air cooled, Open Compute standard data centres,” explained the company.

We spoke to Nvidia’s senior product manager for GPU Computing, Will Ramey, ahead of the launch, who has been working on the Big Sur project alongside Facebook for some time.

“The project is the first time that a complete computing system that is designed for machine learning and AI will be released as an open source solution,” said Ramey. “By taking the purpose-built design spec that Facebook has designed for their own machine learning apps and open sourcing them, people will benefit from and contribute to the project so it can move the entire industry forward.”

While Big Sur was built with Nvidia’s new Tesla M40 hyperscale accelerator in mind, it can actually support a wide range of PCI-e cards in what Facebook believes could make for better efficiencies in production and manufacturing to get more computational power for every penny that it invests.

“Servers can also require maintenance and hefty operational resources, so, like the other hardware in our data centres, Big Sur was designed around operational efficiency and serviceability,” Facebook said. “We’ve removed the components that don’t get used very much, and components that fail relatively frequently – such as hard drives and DIMMs – can now be removed and replaced in a few seconds.”

Perhaps the most interesting aspect of the Big Sur announcement is Facebook’s plans to open-source it and submit the design materials to the Open Compute Project. This is a bid to make it easier for AI researchers to share techniques and technologies.

“As with all hardware systems that are released into the open, it’s our hope that others will be able to work with us to improve it,” Facebook said, adding that it believes open collaboration will help foster innovation for future designs, and put us closer to building complex AI systems that will probably take over the world and kill us all.

Nvidia released its end-to-end hyperscale data centre platform last month claiming that it will let web services companies accelerate their machine learning workloads and power advanced artificial intelligence applications.

Consisting of two accelerators, Nvidia’s latest hyperscale line aims to let researchers design new deep neural networks more quickly for the increasing number of applications they want to power with AI. It also is designed to deploy these networks across the data centre. The line also includes a suite of GPU-accelerated libraries.

Microsoft Updates Yammer

Comments Off on Microsoft Updates Yammer

Microsoft unveiled a bevy of improvements to its Yammer enterprise social network, focused on helping people connect more easily with their teams.

By default, people who access Yammer via their web browser will be taken to a new “Discovery” feed on the service’s home page that is supposed to better show them relevant content from their groups along with other public teams across their company’s network. It’s supposed to help keep people in closer touch with important discussions they may be missing on Yammer.

After users finish reviewing new content in one group, Yammer will display a pop up banner with a link to the next group they’re subscribed to that has new content. Yammer’s mobile apps will get similar functionality through a new Group Updates feed that lets users see a list of different conversations in various groups all on one screen. That way, they won’t have to look through individual groups to get the same information. That feature will begin rolling out on Android first before making it to Yammer’s iOS app.

In addition, Yammer is also tweaking the design of individual groups’ pages. Now, each group will have a full-width banner at the top of its page, and discussions within the group can now take up a wider space on the page to aid in lengthier discussions. The whole page has also been redesigned to focus users’ attention on important content.

Icons in the left-hand sidebar will show the users that are active in groups they are a part of, so they can stay up-to-date on where conversations are happening in real time. It’s a move that could make Yammer more competitive with popular chat solutions like Slack, which has been growing incredibly rapidly and was recently valued at $2.8 billion.

Yammer’s mobile app also gained support for attaching files from external storage services like OneDrive and Dropbox, inviting coworkers to a user’s network by email and mentioning people in comments.

There’s even more up Yammer’s sleeve on top of all these updates. The social network’s iPhone app will soon have a companion version for the Apple Watch that will let people interact with content from their coworkers.

The updates come at a time when Microsoft is putting more effort into improving its workplace collaboration tools.

Yahoo Unveils Livetext Mobile Messaging App

Comments Off on Yahoo Unveils Livetext Mobile Messaging App

Yahoo unveiled a mobile messaging app that combines texting with live one-on-one video.

The app, named Livetext, is video calling with a twist: there’s no audio. To communicate, users type texts and emojis that are overlaid onto the screen during the call.

The app’s format might sound restricting, but Yahoo says Livetext will help users to communicate more freely. The lack of audio, the company says, removes inhibitions that people might feel when they otherwise receive video calls in public.

“We wanted to bridge the gap between the simplicity and ease of texting, with the live feeling of calling,” said Adam Cahan, senior vice president of video, design and emerging products at Yahoo, during the app’s unveiling at an event in New York on Wednesday that was webcast.

Livetext was developed from scratch at Yahoo. Its development was aided by Yahoo’s acquisition last year of mobile messaging app MessageMe, the company said Wednesday. It’s yet another messaging app in a sea of competitors like Snapchat, WhatsApp and Facebook Messenger.

Still, Livetext is the latest attempt by Yahoo to provide a messaging app that resonates with users. It became available to download for free on Thursday for iOS and Android, in the U.S., U.K, Canada, Ireland, Germany, France, Hong Kong and Taiwan. Users will be able to text in English, French, German and Chinese using the app.

The app streams video only when two people are connected through the app at the same time. Users can search for friends in the app through their Livetext user name, or through the contacts list on their phone.

There is no time limit on calls placed through the app, and no way to save or archive the sessions. The video quality will depend on the strength of the data connection, although connections at 3G and above should suffice, Yahoo said.

It’s available on Android and the desktop, but not on iOS.

Comments Off on Microsoft To Release Advanced Threat Analytics

Microsoft is very close to releasing Advanced Threat Analytics (ATA) the security sure-up that it first announced three months ago.

ATA, or MATA as we called it for our own small amusement, is the result of three months’ real world testing, and the culmination of enough user feedback to inform a final release.

That final release will happen in August, which should give you plenty of time to get your head around it.

Hmmm. Microsoft’s Advanced Threat Analytics seems like a very good idea focused on the enterprise.

— Kevin Jones (@vcsjones) May 4, 2015

Idan Plotnik, who leads the ATA team at Microsoft, explained in an Active Directory Team Blog post that the firm is working towards removing blind spots from security analytics, and that this release should provide a strong and hardy tool for the whacking away of hacking.

“Many security monitoring and management solutions fail to show you the real picture and provide false alarms. We’ve taken a different approach with Microsoft ATA,” he said.

“Our secret sauce is our combination of network Deep Packet Inspection, information about the entities from Active Directory, and analysis of specific events.

“With this unique approach, we give you the ability to detect advanced attacks and stolen credentials, and view all suspicious activities on an easy to consume, simple to explore, social media feed like attack timeline.”

The Microsoft approach is an on-premise device that detects and analyses threats as they happen and on a retrospective basis. Plotnik said that it combines machine learning and knowledge about existing techniques and tactics to proactively protect systems.

“ATA detects many kinds of abnormal user behaviour many of which are strong indicators of attacks. We do this by using behavioural analytics powered by advanced machine learning to uncover questionable activities and abnormal behaviour,” he added.

“This gives the ability for ATA to show you attack indicators like anomalous log-ins, abnormal working hours, password sharing, lateral movement and unknown threats.”

A number of features will be added to the preview release, including performance improvements and the ability to deal with more traffic, before general availability next month.

Comments Off on Apple Pay Headed To Canada

Apple Inc is gearing up to launch its electronic payments service in Canada in November, the first international expansion of Apple Pay, the Wall Street Journal reported, citing people familiar with the matter.

The iPhone maker is in talks with Canada’s six biggest banks, Royal Bank of Canada, Toronto-Dominion Bank , Bank of Nova Scotia, Bank of Montreal, Canadian Imperial Bank of Commerce and National Bank of Canada, the people told the Journal.

The banks are open to an agreement, but are not happy with Apple’s fee proposals and are worried about security vulnerabilities like the ones that U.S. banks experienced, the Journal said, citing the people.

It was still unclear if all six Canadian banks would launch Apple Pay at the same time, the Journal said.

Apple launched the service, a mobile payment app that allows consumers to buy things by holding their iPhone6 and 6 Plus devices up to a reader, in the United States in October.

Comments Off on LinkedIn Acquires Startup Refresh

In a move that could produce even more automated suggestions and tips for LinkedIn users, the professional network has purchased California startup Refresh, the maker of an app that gathers news and insights about participants in meetings.

Launched three years ago, Refresh is designed to be a “digital briefing book” that can call up online information related to people that users are scheduled to meet. The information can be anything from blog posts, news articles or Facebook posts to personal notes or favorite sports teams.

The Refresh mobile and desktop app is aimed at helping people relate to one another more quickly, but it can also be used to refresh one’s memory when running into acquaintances unexpectedly.

The details of the deal were not disclosed. Refresh has stopped taking on new users and its app will shut down April 15.

“Refresh has surfaced insights associated with hundreds of millions of meetings, and has been central to countless connections and closed deals,” co-founder Bhavin Shah wrote on the Refresh blog in announcing the deal.

LinkedIn already has an app called Connected that was somewhat of a rival to Refresh. It can log the people users have met and offer updates and information about interests shared with “connections,” which are acquaintances in the LinkedIn lingo. It’s unclear whether Refresh features will be added to Connected or the LinkedIn website itself.

“Our team will focus its efforts on providing LinkedIn members with more insights to help them better do their jobs,” Shah wrote.

Google Moves To Drop CAPTCHA

Comments Off on Google Moves To Drop CAPTCHA

Google announced that it is trying to get rid of those annoying CAPTCHAs required by websites, which is short for Completely Automated Public Turing test to tell Computers and Humans Apart.

Instead of requiring that users fill in the letters and numbers shown in a distorted image, sites that use Google’s reCAPTCHA service will be able to use just one click, answering a simple question: Are you a robot?

“reCAPTCHA protects the websites you love from spam and abuse,” wrote Vinay Shet, product manager for Google’s reCAPTCHA service, in a blog post. “For years, we’ve prompted users to confirm they aren’t robots by asking them to read distorted text and type it into a box… But, we figured it would be easier to just directly ask our users whether or not they are robots. So, we did! ”

Google on Wednesday began rolling out a new API that rethinks the reCAPTCHA experience.

CAPTCHA “can be hard to read and frustrating for people, particularly on mobile devices,” said Zeus Kerravala, an analyst with ZK Research. “People often have to put in the text several times. On the surface, this seems a good way to improve the user experience. It still requires human intervention, just something simpler.”

CAPTCHAs were created to foil computer programs that hackers or spammers use to troll for access to websites or to collect email addresses.

Google said CAPTCHAs are less useful than they have been, although they are still frustrating to everyday users.

“CAPTCHAs have long relied on the inability of robots to solve distorted text,’ wrote Shet. “However, our research recently showed that today’s artificial intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test.”

The new API, along with Google’s ability to analyze a user’s actions — before, during, and after clicking on the reCAPTCHA box — let’s the new technology figure out if the user is human or not.

“The new API is the next step in this steady evolution,” Shet stated. “Now humans can just check the box and in most cases, they’re through the challenge.”
