Security and Risk Online - Visa Payment Card Details Guessed in Seconds by Hackers

Security and Risk Online - Visa Payment Card Details Guessed in Seconds by Hackers

Visa payment card details guessed in seconds by hackers, claims study

 

Cyber crooks can use computers to make multiple attempts to get confidential data without their illicit efforts being discovered

 

Fraudsters can take as little as six seconds to guess the details needed to hack a Visa debit or credit card, research has found.

 

Experts from Newcastle University said it was "frighteningly easy" to do with a laptop and an internet connection.

 

The hackers use a so-called Distributed Guessing Attack to get around the online security features.

 

It may have been the method used in the recent Tesco Bank hacking scam, which affected 9,000 customers and cost £2.5m.

 

The researchers found even if the cyber criminals made multiple - and unsuccessful - attempts to get payment card data, their efforts would not be detected.

 

It meant the scammers could systematically fire up different variations of security data at hundreds of websites simultaneously and, within seconds, the criminals could use a process of elimination to verify, via computer, the correct details of a card.

 

PhD student Mohammed Ali said: "This sort of attack exploits two weaknesses that, on their own are not too severe, but, when used together, present a serious risk to the whole payment system.

 

"Firstly, the current online payment system does not detect multiple invalid payment requests from different websites.

 

"This allows unlimited guesses on each card data field, using up to the allowed number of attempts - typically 10 or 20 guesses - on each website.

 

"Secondly, different websites ask for different variations in the card data fields to validate an online purchase. This means it's quite easy to build up the information and piece it together like a jigsaw.

 

"The unlimited guesses, when combined with the variations in the payment data fields make it frighteningly easy for attackers to generate all the card details one field at a time.

 

"So even starting with no details at all other than the first six digits - which tell you the bank and card type and so are the same for every card from a single provider - a hacker can obtain the three essential pieces of information to make an online purchase within as little as six seconds."

 

Responding to the study findings, Visa said: "The research does not take into account the multiple layers of fraud prevention that exist within the payments system, each of which must be met in order to make a transaction possible in the real world.

 

"Visa is committed to keeping fraud at low levels and works closely with card issuers and acquirers to make it very difficult to obtain and use cardholder data illegally.

 

"For consumers, the most important thing to remember is that if their card number is used fraudulently, the cardholder is protected from liability."

 

The study was published in the academic journal IEEE Security & Privacy.

Hawkfield Consultants Review: The Role of Art Gallery

Art gallery, without a doubt, plays an important role in the art industry. Many people do not possess in-depth knowledge on the role of art galleries in our society. Here is an overview of what an art gallery is and its importance in our society.

 

Art gallery offers a striking place where visitors can view and appreciate art. Various forms of visual arts are displayed such as paintings, sculptures, relics, pottery, jewelries with historical values and much more. Art galleries display art works to promote art and artists as well as to help and guide buyers in selecting art works that will suit their art preferences. A certain type of art gallery like Hawkfield Gallery offers a special type of service to their clients – to help them hunt art works that interest them and even help them bid at auction houses.

 

For those who are curious on the value of the artworks they possess, Hawkfield Gallery and its fine art consultants provides professional advice on how to appraise fine artworks, antiques and collectible items. Hawkfield Gallery gained experience and expertise in determining the value and quality of artworks by visiting auctions houses and antique shops. They use a sales comparison approach to value an artwork - comparing it to similar artworks recently sold or currently for sale on the marketplace. They also welcome artists to present their artworks and to help them determine its fair market value. Visit the gallery’s website to know more about their services and the list of artists they represent.

 

Art Consignment Agreement

 

Most art galleries work with artists on a consignment basis. Consignment is when you lend your artwork on the gallery and the gallery agrees to sell your artwork for a commission percentage. In some cases, engaging in a consignment agreement comes with a lot of risks as it may cause financial or ownership trouble down the road. Make sure to choose the right and trusted gallery that will represent your artwork. Hawkfield Gallery has gained an established reputation in the marketplace that will make you want to trust the gallery and its owner.

Best Things to Do in Singapore by Bacall Associates Travel

Singapore is without any doubts the most developed, urbanized country in Asia, if not in the world. I have stayed there for 4 days, which appeared to be not enough to fully discover this unique country-city.

 

I had a lovely Russian couple showing me around. They live there, so they showed me the best spots to visit while in Singapore as well as how to save significant sums of money on sightseeing and restaurants in Singapore. Continue reading to know more.

 

Here you go, my TOP 9 things to do in Singapore:

 

1.      SUPER TREE SHOW

 

Super Tree Grove is just WOW, seriously! I cannot even describe it properly, but I felt like I stepped in a fairy tale, “Yulia in Wonderland” maybe.

 

The Garden Rhapsody is a show (more like something from outer space) that is held in Gardens by the Bay every evening. The futuristic looking trees/mushrooms are lighted up in different ways together with the music. Every detail is perfectly tuned to create an atmosphere that will give you a fantastic feeling of wonder and stimulate your mind.

 

I think EVERYBODY should see it; it really went beyond my expectation and imagination. It is my dream to take my parents there now!

 

I tried to capture the beauty and the atmosphere with my camera – did not work. You will have to come see it by yourself, sorry.

 

TIP: The show is twice a day, at 7 45 p.m. and 8 45 p.m. and takes around 10 minutes. Make sure to come a bit in advance, so that you take the coolest spot!

 

By the way, the outdoors shows are all free in Singapore, for example like the next one:

 

2.     WATER SHOW

 

Water show Singapore

 

We always missed this one for various reasons, but when we finally reached it, it was definitely worth it!

 

Singing fountains with projections on it, bubbles everywhere and this amazing atmosphere of a holiday everyday – don’t miss it while in Singapore!

 

The earliest one starts at 8 p.m. at Marina Bay Sands, the best view point is just near the Louis Vuitton boutique.

 

3.     THE CLOUD FOREST

 

Cloud forest Singapore

 

Ever wondered how concrete jungles might look like?

 

Singaporeans have created a whole new concept out there with planted walls, artificial waterfalls – something’s absolutely surreal! You can learn a lot about rare plants, take some great pictures, enjoy a magnificent view from to the Marina Bay Sands and just walk around this mysterious world built by man.

 

The entrance prices are here:

 

Is it worth it to go to the Flower Dome? My friends told me “Not really”, so I skipped it.

 

TIP1: Make sure to have at least 1, 5 hours of your spare time, and bring a jacket, as it is quite chilly and moist inside the conservation area.

 

The prices are below. Note, that if you are a student, do not forget to take your student ID with you – the entrance fee will be just 1$ instead of 5 $ for you.

 

TIP2: Try to visit in the morning when it is not too hot.

TIP3: If you want to visit the Cloud Forest and Flower Dome with a private transfer, get this tour, it is a very good deal!

Rules for Successful Staff Management by Meir Ezra

If you can successfully manage people, you get more done and do more good with a group than you can as an individual. You are paid well because you are valuable to your company or organization. In fact, the best-paying jobs in this world are given to managers because good managers are so rare.

 

Managing people is a skill anyone can learn. Like operating a computer or repairing a car, you simply learn how management works, get some experience and bang! You're a good manager.

 

Unfortunately, they do not teach people management skills in traditional schools. Even business schools do not teach you how to hire people, improve their performances, resolve their disagreements, boost their morale and so on. Until L. Ron Hubbard worked out the skills and techniques you need for managing people, you had to learn how to manage on your own.

 

In the previous article two weeks ago, we described six rules for Successful Staff Management. These next six rules are also based on the article by L. Ron Hubbard called "How to Fill Jobs."

 

*Be sincere about your purpose.

 

Of course, before you can be sincere about your purpose, you need to work out your purpose as a manager. Examples: "Help my staff produce more than ever." "Ensure my group reaches the objectives established by my boss." "Support the purpose of our organization and make our customers very happy."

 

Once you have your purpose, you must be genuine about it. If you are insincere about your purpose, as a manager, you will fail.

 

For example, Lucy says her purpose as a restaurant manager is to help thousands of people eat healthy food, while enjoying a pleasant environment. But in reality, Lucy's real purpose is to get as much money for herself as possible, no matter what it takes. So she buys low-quality food, pays employees as little as possible and steals the extra cash. She quickly fails as a manager because the customers hate the bad food and lousy service. The restaurant owner catches her stealing and calls the police.

 

David, on the other hand, sincerely wants to run a fantastic hair salon. He makes deals with the best hairdressers in town so they all get bonuses IF the shop succeeds. David's sincerity shows in his actions. For example, he personally calls all customers a few days after their appointments to ensure they are still happy. Dave succeeds and the owner lets him buy in as a partner.

 

*Never send angry or upsetting written communications.

 

E-mails, memos, notes and letters are permanent records. Everything you write may be stored in a file forever. As a manager, you learn that sooner or later, some of your nasty notes will come back to hurt you.

 

For example, your assistant makes you angry when she forgets to mail a check. You write a note that says, "Flo, you stupid, stupid cow! Take that _____ check to the post office right now!"

 

One year later, Flo becomes your boss's assistant. While walking to an appointment with your boss, you pass her big new desk and notice your "stupid cow" note laying there.

 

*Do not load your staff with so much work that they do not feel they are succeeding.

 

Managers get a bad reputation when they demand more than their people can handle. For example, your delivery people ship 1000 boxes per day. You demand 2000 boxes per day, with no extra help. They work very hard and get 1200 boxes shipped. They are proud of their increased production, but you are not.

 

You yell and scream for 2000 boxes. They realize they will never meet your demands and just pretend to try. They call you "Mr. Hitler" behind your back.

 

Because they no longer care about their jobs, they drop to 750 boxes. They decide you will be firing them all, so why try?

 

As YOU are getting fired, you realize you should have been happy with 1200 boxes. You should have then figured out how to reach 2000 boxes without overloading your team.

5 Things to Know About the Cost for Knee Surgery by Howard Marans MD

Howard J. Marans, MD, discusses the cost for knee surgery.

 

Here are five things to know:

 

1. There are two main type of knee surgery: open knee surgery and arthroscopic knee surgery.

 

2. Open knee surgery is most commonly used to treat more extensive knee problems, such as total knee replacement for arthritis.

 

3. Arthroscopic surgery is a minimally invasive form of surgery that can be used to treat less extensive knee problems, like meniscus or ligament tears. It is preferable to use arthroscopic knee surgery whenever possible, due to its lower risk factors, shorter downtime and lesser costs.

 

4. There are several factors that can influence the cost of knee surgery:

 

  • How high the local cost of living is

 

  • Whether or not open knee surgery is used

 

  • Whether or not a hospital stay is required

 

  • How long it takes to perform the surgery

 

  • How many resources the surgery takes to perform

 

  • What the individual surgeon's rates are

 

5. Insurance covers orthopedic knee surgery costs because knee surgery is only used in cases where it is medically necessary, but the different insurance policies vary widely in the terms of their coverage.
