Nuna9 - Revolutionary


Nuna9 has been designed differently from anything that has ever been created in the solar racing world and the most significant aerodynamic change is that the nose of the Nuna9 has now become more compact and does not tend to overhang any longer.

 The organisers of the Bridgestone World Solar Challenge tend to control the regulations for each edition. The solar panel this year is only allowed to be a maximum of 4 m² in comparison to 6 m² in the earlier race. The team aerodynamicist, Jasper Hemmes, had explained that the design of Nuna9 tends to signify a new step ahead in solar racing.

As a consequence of the change to the World Solar challenge regulation, the need of a smaller solar panel had been utilised on cars of this year. This could mean that they had to make dramatic modifications to the car and eventually they had reached at this exceptional shape. The details of the solar car had not been kept undisclosed till date, from the competitors.

Sander Koot, team captain had stated that Nuna9 is revolutionary and the shape of the car is totally different to the earlier solar cars. They wanted to keep the new shape a secret for as long as possible to refrain from letting the competition in the open.

Take on the Dutch Nuna9


In recent years, the gap between the different teams during the race had been lessening down. They also had seen elements of the earlier solar cars reflected in what the other teams had been in the race. It had been naturally important to them once again in bringing home the world championship title this year.

This was the reason why the TU Delft students have kept the interior of the car away from interfering eyes. Sander chuckled that they do not want to go giving them ideas. After winning the race on various cases as well as the reigning world champion, the Nuon Solar Team is said to be the clear favourite to take the title home in Australia.

The controllers of the race have now been utilising the slogan `Take on the Dutch’ in order to challenge teams from across the world to try and overcome the team from TU Delft. To characteristically direct their winning mentality, the team had intended to mount a lion’s mane on their solar car.

Mane of Lion – Symbolic of Dutch Pride/Glory


Sarah Bennink Bolt, a member of the team had explained that the mane radiates strength and the larger the lion’s mane, the stronger and more invincible he is. The mane of the lion is also symbolic of Dutch pride and glory. The Nuon Solar Team for this year tends to comprise of sixteen students.

They will be defending their world title in October 2017 during the Bridgestone World Solar Challenge with Nuna9, their self-built solar car. The TU Delft students had won the race in total of six times inclusive of the last edition of the race in 2015. They had covered over 3,000 kilometres and the track had stretched around Australia, from Darwin to Adelaide.

How to Record Calls on Your Smartphone

Smartphone

Seek Permission before Recording


Recording a call is said to be one of the most reliable means of capturing a conversation though not very convenient. It needs an external gadget which can be linked to a digital recorder to the base and handset of a desk phone. With the entry of smartphones, this has turned out to be quite easy in most areas; though a disappointment since none of the leading mobile operating systems have included a built-in call recorder.

This could be due to some countries or states having a law against recording call without the consent of all parties in the conversation. However in the present scenario, smartphone apps together with cloud services tend to make recording conversations easy and convenient irrespective of chatting with White House officials or not.

Anthony Scaramucci, as Communications Director of White was out after ten days owing to an open late-night phone conversation with New Yorker writer, Ryan Lizza. Similar to most of the journalists, Lizza had recorded his call not for successors but for proof and with audio evidence it tends to get difficult to debate on that issue.

State laws tends to differ significantly with regards to recording phone calls and some may need both parties to approve in recording the conversation and hence it is essential to check the laws of the state and seek permission before indulging in recording. Recording conversation can be done by:

Using an App


iPhone or Android devices do not come with a built-in call recorder though their respective app stores come with a variety of options for downloading.

TapeACall 



This seems to be a favourite with the journalists since the app is made available on iOS as well as Android at $10, which makes recording easy as setting up a three-way call. You could dial the TapeACall line and dial the person you would prefer to talk to and merge the two calls in a conference. The recordings are saved within the app and one can share them through Dropbox, Google Drive or Evernote.

It tends to put out a free version too though one can access only the first 60 seconds of the recording. If one intends talking for over a minute, it is worth indulging for the Pro version. As the app tends to utilise a three-way calling in order to record the conversation, one would need to have a service plan which can sustain three-way calls.

Recording – Privacy Violation 



There are also several other apps which enables you to record for free such as Another Call Recorder for Android. Google Voice also tends to provide free recording but the procedure tends to be a bit fussy One needs to first enable call recording on the account of Google Voice and then can record when calls comes in to your Google Voice number.

The service also tends to announce when the recording has started. When one hangs up, Google tends to save the recording right into your inbox. Recording calls is said to be a privacy violation though there could be several useful reasons for the same. It can be beneficial while conducting phone interviews or in receiving complicated instructions which would be difficult to note down or when one would prefer storing an intimate moment of some personal event, on their phone.

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.
