In recent years, the issue of credit card fraud has become a major concern for both consumers and businesses. With the rise of online shopping and digital transactions, criminals have found new ways to exploit vulnerabilities in the system and steal sensitive financial information. One of the most notorious platforms for buying and selling stolen credit card data is, a dark web marketplace that has been operating since 2015. However, a recent examination by cybersecurity experts has uncovered some shocking details about this underground network. In this blog post, we will delve into the findings of this investigation and shed light on the inner workings of Briansclub.

The Rise of Briansclub

Briansclub first emerged on the dark web in 2015 and quickly gained notoriety as one of the largest and most active marketplaces for stolen credit card data. It was named after its founder, Brian Krebs, a well-known cybersecurity journalist who has been investigating cybercrime for over a decade. The platform operates on the Tor network, making it difficult for law enforcement agencies to track down its users and shut it down.

Briansclub works like any other e-commerce website, with sellers listing their products and buyers making purchases using cryptocurrency. The platform offers a wide range of stolen credit card data, including card numbers, expiration dates, CVV codes, and cardholder names. These data are obtained through various means, such as phishing scams, malware attacks, and data breaches. The prices of the stolen data vary depending on the type of card, its validity, and the country of origin.

The Investigation

In October 2019, a team of cybersecurity experts from Gemini Advisory conducted an in-depth investigation into Briansclub. They analyzed over 7 million stolen credit card records that were listed on the platform between June 2019 and August 2019. The findings of this investigation were published in a report titled “Briansclub: The Rise and Fall of a Dark Web Marketplace.”

The Scale of the Operation

The first shocking revelation from the investigation was the sheer scale of Briansclub’s operation. The platform had over 126,000 unique buyers and more than 500,000 stolen credit card records listed for sale during the three-month period. This translates to an estimated revenue of $126 million, with each record being sold for an average price of $500.

The investigation also uncovered that Briansclub was not just a one-man operation. It had a team of administrators, moderators, and sellers who worked together to keep the platform running smoothly. The administrators were responsible for maintaining the website, while the moderators ensured that the listings complied with the platform’s rules. The sellers, on the other hand, were the ones who provided the stolen credit card data.

The Canister Commercial Centers

One of the most interesting findings of the investigation was the discovery of what the researchers called “Canister Commercial Centers.” These were groups of sellers who collaborated to provide a constant supply of stolen credit card data to Briansclub. These centers were named after the type of canisters used to store the stolen data, which were then sold in bulk to the platform.

The researchers identified six Canister Commercial Centers, each with its own unique name and logo. These centers were located in different parts of the world, including the United States, Europe, and Asia. They operated like small businesses, with their own marketing strategies, pricing models, and customer service. The collaboration between these centers allowed Briansclub to have a steady supply of stolen credit card data, making it one of the most reliable sources for cybercriminals.

The Impact of Briansclub

The existence of Briansclub has had a significant impact on both consumers and businesses. For consumers, it means that their sensitive financial information is at risk of being stolen and used for fraudulent activities. This can result in financial losses, damaged credit scores, and a lot of stress and inconvenience.

For businesses, the impact is even more severe. The rise of Briansclub has led to an increase in credit card fraud, which costs businesses billions of dollars every year. It also damages their reputation and erodes consumer trust, which can have long-term consequences for their bottom line.

The Role of Law Enforcement

Despite its illegal nature, Briansclub has been operating for over five years without any significant intervention from law enforcement agencies. This raises questions about the effectiveness of current measures in combating cybercrime. The investigation by Gemini Advisory has shed light on the inner workings of this dark web marketplace, providing valuable insights for law enforcement agencies to take action.
