1. Security Problem/Incident
The theft of payment card information has become a common issue in today’s society. Even after the lessons learned from the Target data breach, Home Depot’s Point of Sale systems were compromised by similar exploitation methods. The use of stolen third-party vendor credentials and RAM scraping malware were instrumental in the success of both data breaches. Home Depot has taken multiple steps to recover from its data breach, one of them being to enable the use of EMV Chip-and-PIN payment cards. Is the use of EMV payment cards necessary? If P2P (Point to-Point) encryption is used, the only method available to steal payment card data is the installation of a payment card skimmer. …show more content…
The unfortunate thing is the way the attackers infiltrated the POS networks and how the attackers were able to steal the payment card data, were the same methods used in the Target data breach. The attackers were able to gain access to one of Home Depot’s vendor environments by using a third-party vendor’s logon credentials. Then they exploited a zero-day vulnerability in Windows, which allowed them to pivot from the vendor-specific environment to the Home Depot corporate environment.
Payment card information is sold by cyber-criminals frequently. In more recent retail breaches, they have been able to steal payment card information from millions of customers and sell it online in what is known as the “Darknet.” Once the cyber-criminal has stolen the payment card information, there is a process that takes place in order to put the information on sale on the Darknet and for the cyber-criminals to make money. The first step in the process is selling the payment card information to brokers. The brokers buy the payment card information in bulk and sell the information to “carders” on carder websites. The definition from “How ‘carders’ trade your stolen personal info” says, “Carders are the people who buy, sell, and trade online the credit card data stolen from phishing sites or from large data breaches at retail stores”. An example of a carder website is Rescator shown in Figure 1 below (Lawrence, 2014). As you can see, the site has full search capabilities based on the type of card you are searching
