Aston Martin’s Valkyrie Hypercar Gets Closer To Production

The Aston Martin Valkyrie


Aston Martin and F1 team Red Bull Racing had revealed their innovative hypercar dubbed AM-RB 001 in July 2016. At the Geneva Motor show, the real name of the car had been eventually disclosed to the world - `The Aston Martin Valkyrie’.

It comes charged with crafting a road car built exceptional invention partnership with Red Bull and Aston Martin wherein the collaboration had designed a car similar to which has not been seen till now. The designer Marek Reichaman of Aston Martin and Adrian of Red Bull Racing have been working together on all aspects of the project striving to make sure that the care is totally useable as well as enjoyable as a road car though with the potential of performing like no other road car on a race track.

For those interested in driving experience, a track-only version is in progress and the probable performance is in line with the prevailing LMP1 Le Mans sports prototypes. Valkyrie tends to continue the tradition of `V’ cars of Aston Martin that had started in 1951 with the Vantage and had been selected as a name to distinguish high performance variants of the present model, the DB2. It continued this lineage in the Virage, Vanquish and Vulcan.

Fabricated Around Lightweight Carbon Fibre Structure


The Valkyrie, fabricated around a lightweight carbon fibre structure tends to have thorough aerodynamics which is said to deliver unique stages of down-force in a road-legal car wherein most of the down-force has been produced through the underfloor aerodynamics.

The same had been constructed by David King together with his team for purpose-built facility developed for the original hypercar, the One-77 of Aston Martins. The Valkyrie is said to be a hybrid, a reunion of a 6.5-litre V 12 with a type of electric powertrain developing more than 1,000 horsepower. There is a bespoke seven-speed paddle-shift transmission coupled to the all-new engine.

It has been designed and manufactured to the specifications of Ricardoto Red Bull Advanced Technologies, where the gearbox would be an appropriate partner to Cosworth’s V12 engine. Besides assigning the ultimate road-legal car, the Valkyrie also tends to boast of a lightweight hybrid battery system provided by Rimac. The Croatian company, recognized as the world leaders in high performance battery technology, has also showcased its competences with the innovative Concept-One which is said to be the first and the fastest electric hypercar in the world.

AM-RB 001 Needs Braking System


Comprising of a power-to-weight ratio of 1:1 – 1 horsepower for each kilogram of kerbweight, the AM-RB 001 needs a braking system which tends to be more than equal of its powertrain. Alcon and Surface Transforms, together tend to be responsible in supplying the lightweight, high performance brake calipers together with carbon discs required in delivering the stopping power.

Electronic experts, Bosch, Transmission Control Unit –TCU and Electronic Stability Programme – ESP has been entrusted with developing bespoke engine Control Unit – ECU, to permit maximum efficiency, performance together with dynamic control while UK light manufacturer, Wipac is in charge for the full LED headlamps and tail lamps of the hypercar.

How Hackers Hijacked a Bank’s Entire Online Operation

Hackers

Extraordinary Incident of Wholesale Bank Fraud Done by Hackers


Hacking a bank is not different from the out-dated means of raiding it and hackers can get in and out with the goods quite easily. However a particular enterprising team of hackers aiming a Brazilian bank seemed to take a much more inclusive and a scheming method of operation.

On a certain weekend afternoon, they had rerouted all the online customers of the bank to effortlessly reconstructed fakes of the bank’s properties wherein the marks offered over their information of the accounts. The researchers at Kapersky the security firm had defined an extraordinary incident of wholesale bank fraud, which had basically hijacked the complete internet footprint of the bank.

 Last year, on October 22 at 1 pm, the researchers had stated that the hackers had altered the Domain Name System registration of all 36 online properties of the bank, taking the desktop and mobile website domains of the bank to take users to phishing site. That meant that the hackers had the potential of stealing login credentials at the sites which had been hosted at the legitimate web addresses of the bank.

The researchers of Kaspersky were of the belief that the hackers could have also simultaneously redirected most of the transactions at ATMs or point-of-sale systems to their own servers, gathering the details of the credit card of anyone who utilised their card on that Saturday afternoon.

Malware Infecting Customers


One of the researchers of Kaspersky, Dmitry Bestuzhey, who had analysed that attack in real time on seeing malware infecting customers from what seemed to be the fully valid domain of the bank, had stated that absolutely all of the bank’s online operations had been under the control of the attackers for five to six hours.

From the point of view from the hackers, according to Bestuzhey, the DNS attack meant that `you become the bank and everything belongs to you now’. Kaspersky has not revealed the name of the bank which had been targeted in the DNS redirect attack. He has stated that it seems to be a major Brazilian financial company with hundreds of branches, operations in the US and the Cayman Islands, with 5 million customers and over $27 billion in assets.

Though Kaspersky is not aware of the full extent of the damage caused due to the takeover, it should be a warning to banks all over to consider how the insecurity of their DNS would support a nightmarish loss of control of their core digital assets. Bestuzhev had commented that they have never seen it exploited in the wild on such a big scale.

DNS – Vital Decorum Under Cover of Internet


The Domain Name System – DNS tends to serve as a vital decorum running under the cover of the internet and translates domain names in alphanumeric characters such as Google.com, to the IP addresses such as 74.125.236.195, which tends to represent the definite locations of the computers hosting websites or other services related on those machines.

 However attacking the records could take the sites down or redirect them to a destination of a hackers’ choice. For instance, in 2013, the Syrian electronic Army groups of hacker had changed the DNS registration of The New York Times in redirecting visitors to a page with their logo. Recently, the Mirai Botnet attack on the DNS provider Dyn had cracked a main portion of the web offline inclusive of Amazon, Reddit and Twitter.

However the attackers of Brazilian bank had subjugated their victim’s DNS in a much more directed and profit-driven manner. Kaspersky was of the belief that the hackers compromised the account of the bank at Registro.br which is the domain registration service of NIC.br, the registrar for the sites ending in the Brazilian .br top-level domain which is said that it also manages the DNS for the bank.

Changing Registrar – Domains of Bank


The researchers are of the opinion that with that access, the hackers had been capable of changing the registrar at the same time for all the domains of the bank, redirecting them to servers which the attackers had set up on the Cloud Platform of Google.

With the hijacking of the domain, those visiting the website URL of the bank were redirected to the duplicate sites where those sites also had valid HTTPS certificates issued in the name of the bank. Hence those visitors’ browsers portrayed a green lock together with the name of the bank like they would in the real sites. Kaspersky also observed that the certificates was provided six months earlier by Let’s Encrypt, the non-profit certificate authority which makes obtaining an HTTPS certificate easy in case of increasing HTTPS acceptance.

 Josh Aas, founder of Let’s Encrypt had stated that `if an entity had gained control of DNS and had gained effective control over a domain, there could be a possibility for that entity to get a certificate from them. Such issuance would not constitute mis-issuance on their part since the entity receiving the certificate would have been able to properly demonstrate control over the domain’.

Hoaxed Sites Infected with Malware


Eventually the hijack had been so thorough that the bank was unable to even send email. Bestuzhev stated that they could not even communicate with the customers to send them an alert and if your DNS is in control of the cybercriminals, you are basically screwed’. Besides phishing, the hoaxed sites also infected victims with malware download which had disguised itself as an update to the Trusteer browser security plug-in which the Brazilian bank provided the customers.

As per the analysis of Kaspersky the malware gathers not only banking logins from the Brazilian banks but also eight others as well as email and FTP credentials together with contact lists from Outlook and Exchange. All of these had gone to command-and-control server hosted in Canada. The Trojan also comprised of an operation intended to disable antivirus software for infected victim, and could have persisted much beyond the five hour window when the attack had taken place.

The malware had scraps of Portuguese language, implying that the attackers could have been Brazilian. Bestuzhev of Kaspersky debates that for the banks the incident could have been a clear warning to check on the security of their DNS. He notes that half of the top 20 banks ranked by total assets do not manage their DNS but tend to leave it in the hands of a potentially hackable third party and irrespective of who tends to control the DNS of a bank they can take special precautions in preventing their DNS registrations from being changed without safety checks such as `registry lock’, which some registrars tend to provide together with two-factor authentication making it difficult for hackers to change them.

Mono-Live Gadget Review: Sonnet Will Turn Your Phone Into Off-Grid Life Saver

Sonnet

Sonnet – Off-Grid Hexagon

Sonnet which is an off-grid hexagon tends to connect to your phone providing the potential of sending messages or even maps without the need of a cellular or satellite signals. It is the most advanced off-grid Mobile Mesh network and is like a walkie-talkie for your phone.

 It tends to have global offline maps, together with a panic button to send an SOS signal as well as a 4000mAh battery to charge your phone when it is on low charge. Our phones are dependent on mobile network and are unable to keep the user connected when the mobile network is inaccessible or defective like on instance when one is

  • Travelling the backcountry and the network is not available or could have very light coverage 
  • Traveling abroad and the network tends to be unreliable or very expensive 
  • Attending crowded events where the network tends to be slow and congested having too many users around the place 
  • Encountering a natural disaster where the network service tends to get disrupted or totally damaged 

Walkie-talkies have a tendency of functioning anywhere though they could be:

  • Massive and burdensome and some may weigh tons while carrying them around the place 
  • Complex and unintuitive where plenty of tuning and setup may be needed before it could be utilised 
  • Very low-quality audio with no text, image. It tends to have bad audio which may at times lead to miscommunication
 

Sonnet Super Advanced Walkie-Talkie

 
Sonnet being an Off-the-Grid communication device enables the user to utilise their smartphone as a super advanced walkie-talkie which has the possibility of sending super advanced walkie-talkie that can send instant message, image data, voice recording as well as GPS Coordinates in the absence of cellular coverage’s and internet access.

Sonnet is said to bring about the long range wireless communication of the walkie-talkie to your smartphone and connect to the smartphone via Wi-Fi relaying any data sent from your phone to other sonnet devices through the long-range radio wave. This tends to remove totally the reliance of the smartphone on cellular grid and the other network infrastructure enabling it to be utilised when there is no cellular connectivity or internet access. It does not have any frequency to tune or channel to be set. The user could only connect and get started with chatting. One can utilise the Sonnet App just the way as any other instant messengers for:

  • One-on-one private messages 
  • Private group messages 
  • Public messages to any users of Sonnet within the range.
 

Sonnet Equipped with SMA Connector

 
Sonnet App tends to run directly in the browser of the smartphone and hence one need not download or install any app. Sonnet is entirely off-the-grid and functions independently of any network infrastructure which means that Sonnet enables the user to remain in touch with friends and colleagues irrespective of where they may be.

 The usual point-to-point range between two devices of Sonnet is 5 km, around 3 miles. This range could be up to 15 km in case of a line-of-sight such as when the sender and the receiver seem to be on top of two mountains. Besides this, Sonnet is equipped with a SMA connector wherein one can connect their own directional antenna for the purpose of increasing the point-to-point range much further.

The mesh network of Sonnet tends to intensively increase the effective range further than the point-to-point range by relaying the data via the other devices. The data can be relayed by Sonnet up to 16 times in achieving a maximum range of 80 km. To use Sonnet there is no need of a subscription fee and one can send as many messages as one desires.

 

In Emergency – Panic Button

 
If one device tends to have internet connection, the entire network can then have access to it. If Sonnet is placed in a car or base where there is availability of internet, then one can have access to the internet in the backcountry by being in possession of another Sonnet. The Sonnet App had an offline map wherein one can get directions and view points of interest without the internet connection. In an event of emergency, the app which has a panic button comes in handy.

You could long press the button for five seconds to activate the SOS mode, broadcast your prevailing GPS location and your distress message is conveyed to all Sonnet users within range. Being equipped with a 4000 mAh lithium polymer battery, it comes with a USB port and hence one can charge your smartphone with it.

Sonnet tends to charge fully most of the smartphones on the market. Sonnet is said to have a rugged design making it compatible for the purpose of out-door use and is rated IP66 meaning that it is dust and water resistant.

This enables the user to bring the Sonnet along no matter where one may intend to travel. Sonnet is secure and all communications done with Sonnet are said to be end-to-end encrypted with AES -256-bit. Moreover, Wi-Fi link between Sonnet and the smartphone are said to be secure with WPA/WPA2.

New 4D Camera Designed by Stanford Researchers

4D Camera

Stanford researchers created a new camera to enhance virtual reality and robot vision

Robotics is advancing at a frantic pace and Stanford researchers giving it a new push by bringing such a technology which can play a remarkable role in its future. A new 4D camera has been built by the researchers which have the ability as the name suggests generating four dimensional images. Furthermore this camera can even capture images in 140 degrees which is unbelievable and one of a kind in itself. This camera will find its way in the robots in upcoming days where it will help them in airborne package deliveries by offering a remarkable view of surroundings.

Camera designed specifically with robots in mind

This 4 D camera has been developed by the team of researchers at the University of California, San Diego. This camera is designed with robots in minds therefore it comes loaded with some exquisite features like wider field of view, light weight and single lens rather the multiple lens used in the modern consumer electronics.

This camera will be showcased at the upcoming computer vision conference called CVPR 2017. Researchers had stressed the current demand of the robotics are quite heavy on the robots wherein they are required move around and gather information from different perspectives in order to understand the varied aspects of the environment.

This camera will help robots in gathering large amount of the information from a single image like never before.Researchers believe that this camera will find wider application in the autonomous vehicles along with the ever growing augmented and virtual reality technologies.

Desirable features for the robotics

If robotics and wearable technologies want to grow by leap and bounds then this new 4D camera will be a boon for them. It has some of the most desirable features like detailed depth information, wider field of view and ability to be manufactured in any shape or size. This would give a great boost of the imagining system incorporated in the robotics, augmented and virtual reality as well as the wearables.


When compared to the conventional cameras, the images taken from the 4 D camera offers a refreshing perspective of looking through a ‘window’ rather than a ‘peephole’. In normal 2D images users can move their head to gain more information but the images taken from this camera allows users to identify features such as shape, brightness, transparency and much more.

The best thing about this 4 D camera is that it can also function as the modern conventional camera at far distances. A unique feature about this camera is that it can enhance the close up images to a great extent which means it can be used for a really wide variety of tasks and operations like it can used in the small robots which tends to navigate small areas in the landing drones or self-driving vehicles.

 Its other characteristic of offering incredible depth information will come in handy in the augments and virtual reality system wherein it will be help in seamlessly rendering real scenes. It will also bring support for better amalgamation between the actual scenes as well as the virtual components in an efficient fashion.
