Introduction to the Business of Stolen Card Data. Introduction. I receive many questions from people who don’t work in the security field about the use of stolen credit card data in the cyber- crime ecosystem, so I decided to provide more information, starting from the clamorous data breach of the U. S. retailer Target. How it is possible to monetize the information stolen during a cyber- attack? How much do sensitive information and stolen credit cards cost and where it is possible to acquire them? Groups of cyber- criminals, mostly located in Eastern Europe and Russia, are part of an organized network that is able to sell these commodities to other criminals who desire to conduct a cyber- attack or to realize a scam.
Ethical Hacking Training – Resources (Info. Sec)Let me start by remarking that cyber- criminals find it more profitable to sell stolen credit cards than to directly use the data gathered for illegal activities. Many countries, including the U. S., still use credit cards based on a magnetic strip that are quite easy to clone; the lack of security measures such as security chips aids cyber- criminals. Fortunately, that is changing and principal financial institutions are working to replace an obsolete technology that exposes card holders to serious risks. ![]() Discover our full range of internal Blu-Ray drives from Pioneer and LG and all at great prices with fast delivery | Ebuyer. The stolen credit card information came from identity theft through large- scale attacks based on botnets, and credit card skimming. Of course, the price for stolen cards is variable and depends on different factors, including the amount, limits of the card, type of card, account balance, and geographic location of the card owner. The price for valid credit cards could reach $1. Deep Web, for example, has plenty of black markets that offer them at cheap prices. E-mail and texting have become important parts of communication in the modern office. Here are 10 tips to help you improve your writing in such mediums. Card numbers are usually sold to brokers who acquire large numbers of stolen card numbers to resell to carders. The stolen card data market is not different from any legitimate marketplace; specialized sellers, escrow agents, resellers, and vendors flock to this specific business segment. The price for valid credit cards can be as high as $1. The amount of banking malware is constant increasing and old malicious codes are renewed, as happened for Zeus crimeware. The proliferation of such agents in responsible for the decrease of the average price for a stolen credit card. The majority of websites that offer stolen card data guarantee their validity and, in some cases, they also provide replacements in case of problems. It All Starts with a Theft. Every illegal activity related to cards begins with the theft of card data or the physical card. Card data used by criminals includes the card account number and all that is necessary to complete a legitimate transaction. The account number, aka the primary account number (PAN), is often embossed on the card while the magnetic stripe on the back is used to archive different information, including the card holder’s name, account number, expiration date, and verification/CVV code. It must be considered that a growing number of web services on the Internet have commercial purposes and collect a huge quantity of information related to users’ card data. Hackers are aware of this and exploit numerous techniques to access the precious information. Access to one of these databases that contains data for millions of card data could open the doors of heaven for a criminal. Despite the fact that principal security firms specialize in card frauds and card issuers constantly monitor suspect activities to discover ongoing card frauds, victims do not often promptly discover the scams and report to law enforcement, so card thieves can operate unpunished for several weeks in the majority of cases. Almost every financial institution has a 2. Without a prompt action by the card issuer, card thieves can purchase huge amounts of money in merchandise before the cardholder or the card issuer discovers the card fraud. The bad news arrives to the cardholder after seeing a billing statement from the card issuer and, in many cases, the amount of stolen money could be considerable. How Crooks Steal Your Data. Every year an impressive number of persons and organizations are victims of card frauds. The Internet carding industry is responsible for the identity theft and financial losses. The crime industry is able to steal an impressive amount of data, including banking credentials, card data, and personally identifiable information to sell and trade on the online black market. The most common risky scenarios that expose users’ data are: The term “skimming” is used to indicate the theft of credit card data used for a legitimate payment. Usually the criminals adopt a small electronic device dubbed a “skimmer” to swipe card data and store user’s credit card information. Skimmers can be placed in front of ATM card readers and used to intercept data about the transaction for payment at markets or in any commercial activity. The use of a skimmer is usually combined with the use of small keypads or hidden cameras to capture the user’s PIN. Figure 1. ATM Skimmer. Data breach via “wardriving”—Cyber- criminals tap wireless networks by positioning their systems in the vicinity of retailers and markets. The attackers are able in this way to inspect network traffic, capturing account numbers as cash registers process purchases. In 2. 01. 0, 1. 1 individuals were charged with computer intrusion, fraud, identity theft, and many other crimes after stealing 4. The criminals tapped the wireless networks of popular retailers including the Sports Authority, TJ Maxx, and Barnes & Noble. Phishing attacks are another common method used by cyber- criminals to steal users’ data. Phishing scams are very well articulated and are increasing in level of sophistication. Victims usually receive unsolicited mails that request them to provide information with the character of urgency (e. Recently the phishers are exploiting new channels, such as social networking platforms and mobile. Users are unaware of the cyber- threats and new schema of attacks have shown their efficiency in recent attacks. Malware- based attacks represent another common method adopted by cyber- criminals to collect banking data to resell in the underground. The amount of banking malware has increased; 2. Case Study: Dexter and the Rise of Malware that Hits the Point of Sales. At the end of 2. 01. Israel- based company Seculert announced that it had detected a new malware called Dexter, used for parsing memory dumps of specific POS software- related processes looking for Track 1/Track 2 credit card data. The Dexter campaigns mainly hit hotels, restaurants, and big retailers in 4. U. S. and the U. K. One year later, Dexter is still active in Russia, the Middle East, and Southeast Asia, but it isn’t the only malware designed to attack point- of- sales systems. In early 2. 01. 3, Group- IB detected a new POS malware called “DUMP MEMORY GRABBER” just a few months after the detection of the popular malware v. Skymmer and Project Hook. Security experts at Intel. Crawler have discovered a huge credit card fraud realized through a point- of- sale botnet mainly based on compromised machines belonging to U. S. merchants. The botnet had infected nearly 1. Subway sandwich shops, stealing 1. The discovery demonstrates the alarming trend toward infecting Po. S machines instead of installing skimmer devices. Figure 2. Point of Sale. The most recent discovery was made by a group of researchers at Arbor Networks in November that found two servers hosting the Windows- based Dexter malware. Arbor Networks senior research analyst Curt Wilson revealed that, while monitoring activity, its team saw 5. Arbor experts haven’t discovered when the infections started; it is likely that the attack was started with a classic spearphishing attack that lured victims to compromised websites hosting Dexter malware or the attackers exploited the knowledge of the default settings of targeted systems. The security firm has reported the discovery to the Financial Services Information Sharing and Analysis Center (FS- ISAC) and, of course, to law enforcement.“The way the attackers had the server set up, we saw credit card data posted to the site … The attackers were clearing the log files periodically, so there’s no telling how long these campaigns have been ongoing,” said Wilson. Arbor experts have identified three different versions of Dexter: Stardust, which represents substantially the original version.
