visa card details at risk

As per one record, sometimes online shopping discourages people because they may become the unfortunate victim of credit card fraud. The people who do online shopping frequently may know that the retailers ask for the additional credit card and debit card data for minimizing the risk of online fraud.

Recently, the students of Newcastle University, UK has conducted one study, and they reveal that hackers have some tactics with the use of which they can crack the visa card data within just 6  seconds. Moreover, Budi Arief, Aad van Moorsel, and Mohammed Aamir Ali has also recently conducted one research and gave it a name “Does The Online Card Payment Landscape Unwittingly Facilitate Fraud?” This article or we can say that the research was published in the academic journal IEEE Security & Privacy.

According to the research team, there is one tool with the hackers with the use of which the hackers can reveal the information of Visa debit/credit card. The software which is used by the hackers can reveal very sensitive information like Visa card CVV number, its expiration date, owner’s address, owner’s postal code, etc. To fetch the information from Visa card has become a very easy task for the hackers now.

How Does This Software Work?

Security code or CVV of the credit card are the compositions of three numbers. The hackers have to make at least 1000 attempts to crack that code. After 1000 attempts, they may successfully conduct the Guessing Attack exploit. The current system for the online payment does not perceive multiple payment requests through different websites, because of this, hackers can make unlimited guesses in every field of the Visa card.

The ultimate result of such type of guesses is that the hackers can use the permissible attempts on each and every website. Normally, this includes 10 to 20 sites. Not only this but also every website has many variations in the data fields for cards. Because of this, the hackers can collate all the scattered data and combine them together easily.

Why Does It Work Only on Visa Card & Not Master Card?

According to the research team, the information of Visa card can be fetched easily in compare to Master card. Moreover, Master card can detect the guessing attacks in maximum ten attempts though the guesses attacks are divided into the several sites.

How to Prevent The Attack?

As per the views of the research team, standardization or centralization is the only solution to prevent from such guessing attacks. If all the merchants offer the same number of fields, it is called the standardization. If such standardization comes into existence, then the hackers can’t do such type of attacks anymore. On the other hand, the centralization is that thing in which the card payment networks or payment gateways are linked with the network. Standardization and centralization provide the essential protection against such attacks. The card holders’ awareness also plays an important role to protect from such attacks.

The card holders should keep their eyes on the suspicious activities or any suspicious payments.
