Card fraud in the deep web

[Administrator]

The majority of activities related to credit card fraud are made in the underground forums and specialized hidden services in the deep web. These environments allow the streamlining of illegal activities related to the commercialization of stolen credit and debit cards and related data. The underground ecosystem represents a portion of cyberspace that is considered crucial for the business of criminal crews that specialize in fraudulent activities related to payment cards.

Underground communities offer various products and services, including the bulk of stolen card data, malicious codes to compromise payment systems (i.e. PoS, ATM), money laundering services, plastic, and card-on-demand services. In these black markets, criminals can easily acquire and sell tools, services, and data for various kinds of illegal activities.

The offer of criminal activities is extremely variegated, security researchers constantly monitor black markets and their evolution in order to identify noteworthy trends, and this is the purpose of the post.

In recent months, principal actors involved in the sale of payment card data are also offering any kind of documentation that is usually used by crooks in more sophisticated frauds.

Passports, driver’s licenses, and utility bills are commonly used by criminal rings for identity theft, an activity that allow them to open a bank account or accounts for other payment services, that are used in the cash-out process.

Banking accounts opened with fake identities are used as payment recipients for the sale of any kind of product and service related to credit card fraud.

Another element to consider is that online crimes related to payment cards are becoming prevalent with respect to credit card cloning. Criminal organizations that sell products and services related to card frauds in the underground find it more profitable to sell stolen card data than use it by cloning legitimate cards and using them.

This depends strictly on geography. In a country like the US where credit cards are still based on a magnetic strip, it has been observed that an impressive amount of credit card fraud involves malware.

2014 was characterized by an impressive sequence of data breaches that compromised hundreds million payments cards, and the retail industry was the most impacted sector according principal security firms.

The effects the black markets offer are evident. Principal sellers in the underground not only offer stolen card data, but are also focusing their offer for customers that intend to run malware-based attacks against companies operating in the retail industry.

Let’s start out tour!

Card frauds – what is possible to buy in the underground?
The credit fraud represents a pillar of the underground economy. The majority of underground markets criminal forums are crowded by sellers that offer products, and services to facilitate, streamline, and industrialize this criminal practice.

Visiting the principal underground communities, it is possible to acquire numerous products and services. For this reason, let’s look at the most popular terms used by crooks:

CVV is a term used to indicate credit card records that may contain several bits of data, including the cardholder name, card number, cardholder address, expiration date, and CVV2 (the three digit code reported on the back of a card). A common error is to confuse CVVs with the code composed of the three digits that is on the back of a payment card.
CCVs are used by criminal crews for online purchases that allow them to cash out the stolen data. The prices for this kind of data range from less than $10 (for U.S. cards) up to $25 (for EU cards sold by sellers with high validity rate).
DUMPs is a term used to indicate raw data stored on the magnetic strip of a smart card. A Dump is usually obtained by physical skimming the card or by using a point-of-sale malware that is able to scrape the memory of the payment systems to siphon card data. The DUMPs are used by criminal crews to clone legitimate credit cards; their prices depend on multiple factors, including the nation of the cardholder and the card expiration date. A credit card dump cost around $20 – $125, their prices are usually higher of the CVVs because the payoff is bigger.
FULLZ is a term that refers the full financial information of the victim, including name, address, credit card information, social security number, date of birth, and more. The information could be used by crooks to commit more complex frauds. The availability of FULLZ allows hackers to steal the identity of cardholders. This means that they could open temporary bank accounts to use in the cash-out phase. A common abuse of FULLZ data consists in performing bank transactions that request users to provide financial information as an authentication mechanism.
Some sellers also offer FULLZ belonging to deceased people. Despite the fact that they usually include data related to credit cards that are no longer valid, crooks can still exploit them for various kinds of illegal activities. Dead FULLZ could be sued to order new credit cards on behalf of the victim, or open a bank account used for cash out though money mules, or for tax refund scams. Dead FULLZ usually cost around $1-3 each.
Black markets
There are numerous places in the Internet where it is possible to pay for products and services related to card fraud, hacking forums, carding forums and hidden services in the Tor network are the places where it is possible to buy CVVs, DUMPss, and FULLZs.

Apart from rare exceptions, cyber-criminals prefer to purchase stolen credit card data on the black market because these platforms offer escrowing services and high reputable vendors ranked by efficient mechanism based on feedback.

Everyone that searches for stolen card data will find online the name of one of the most prolific carder, the Rescator, which is considered one of the most important players in the underground community that provides any kind of goods related to card frauds.

Rescator manages one of the most popular online marketplace where users can easily buy dumps and CVVs by using a common e-commerce interface. Rascator offers the possibility to choose the product category, the country, any ancillary information like the type of dump (VISA, MasterCard, AMEX, etc.) and the type of card to retrieve.

As shown in the image below, users can also buy card DUMPs filtering by expiration date and banks; this information is very useful for a buyer to acquire data or to use the stolen data to target users in a specific geographic area. For example, the ability to target bank customers in a specific area makes very difficult to discover card frauds with automatic systems because transactions appear as legitimate and goes undetected since the card owners do not report the crime.

As I have anticipated, the anonymity offered by many black markets in the Tor network are attracting a growing number of sellers and buyers.

Every black market has its specialization; some marketplaces mainly sell products like drugs and weapons, other host communities of carders and hackers that offer many products for card frauds.

Conclusions
Let’s close this rapid tour of the principal black markets that offer products and services for card fraud reviewing prices for the goods we have found.

Prices reported in the following table are related to the various offers in the black marketplaces visited during our quick investigation. We have to consider that many sellers allow negotiating the cost per each item and selling sets of hundreds of CVVs and DUMPs at lower prices.

The prices are extremely variable and depend on multiple factors. The trend in the diversification of the offer relies on the availability of a wide range of services, which can induce a buyer to choose a particular seller.

Among these services the escowing, the cash out through custom carding services, and the personalization of the offer according to various parameters, including geography, minimum amount guaranteed and expiring date of credit card data.

I will continue to monitor the evolution of the dark communities in order to report any phenomena of interest.

Stay tuned …

A special thanks to an anonymous informer that uses the pseudonymous of “ping,” which supported me during the investigation and provided precious suggestions on dark communities.

I need some help compiling a list of decent exercises that require absolutely zero equipment and can be done in the home.

Does anyone have any good ones they can share?

Thanks in advance..
