This information has been sourced through data breaches or breaches in other sources such as data mining software programs used for data analysis.


Briansclub was one of the dark web’s most infamous markets that specialized in stolen credit card data, until law enforcement hacking it and shutting it down in 2019. However, similar marketplaces — with even more sinister tendencies — continue to operate online; indeed this underground storefront even earned its name as an ironic tribute to cybersecurity journalist Brian Krebs who wrote for Krebs on Security magazine and unknowingly provided its inspiration.

KrebsOnSecurity recently obtained an unauthorised database containing 26 million BriansClub cards that had been uploaded over four years; it includes valuable intel for banks; it’s estimated that 14 million of the stolen card records still have unexpired expiration dates. Once collected, KrebsOnSecurity acquired it through various means including hacking databases at financial institutions or exploiting vulnerabilities on e-commerce websites and selling them on criminal forums reselling for commission on each sale. KrebsOnSecurity acquired this unauthorised database using various techniques such as hacking into databases at financial institutions or exploiting vulnerabilities on e-commerce websites before selling off on criminal forums where commission was earned on each sale resold from criminal forums often earning commission on each sale they made commission from each sale made on criminal forums often earning commission on each sale made from each sale commission earned from each sale made. KrebsOnSecurity recently obtained purloined 26 Million BriansClub card records uploaded over four years time with 14 Million records still having active expiration dates on them!

Krebs notes it is difficult to assess exactly how many BriansClub cards are in circulation at any one time, though their market keeps stockpiling new batches stolen by cybercriminals and offering for sale on devices such as magnetic stripe readers – giving cybercriminals access to counterfeit cards for purchases on fake spending sprees against other people’s accounts.

BriansClub thrives due to its reputation for offering high-quality stolen card data at competitive prices, which draws buyers. These buyers in turn bring more criminals into its ecosystem – this virtuous cycle allows it to thrive; however, legal action, hacking or other factors could interrupt it and force changes within it.


Criminals make a thriving industry out of selling stolen credit card data on dark web marketplaces. After acquiring this data through hacking, phishing, or skimming operations, criminals sell it on to other criminals who use it to conduct illicit transactions and financial fraud. Dumps — digital copies of magnetic strip data encoded on credit cards that include card number, expiration date and CVV2 code — are one of the key products traded illegally – these contain card number, expiration date and CVV2 code which are essential in conducting fraudulent transactions – making these Fullz invaluable in terms of identity theft schemes as they go beyond carding schemes alone.

BriansClub, a popular cybercrime marketplace, recently published data showing 26 million stolen cards are for sale underground. These cards offer criminals years worth of potential profit with expiration dates that span decades into the future. Furthermore, BriansClub provides various services designed to aid criminal activity such as phishing and spoofing tools; tools to steal magnetic strip data for fraudulent use; as well as tools for tracking bank identification numbers (BINs).

Security experts have noted that BriansClub stands out among its competitors by providing outstanding customer service, an uninterrupted supply of stolen credit card data, and stringent quality control measures. Furthermore, it seems to take pleasure in taunting Brian Krebs of Krebs on Security; indeed its logo features his likeness as does its domain name with an intentional pun on his name.

Due to Briansclub’s widespread appeal, impostor websites have emerged to imitate it and create fake sites featuring similar layouts and color schemes as the authentic domain. Threat actors may become confused between genuine and counterfeit Briansclub sites causing confusion for many visitors.

CVV2 Codes

A CVV2 code is an additional security measure printed on credit cards to identify its authorized user and protect consumers from identity theft by making it more challenging for criminals to steal their identities.

At present, criminals rely on various means to access credit card data. But as payment security standards have tightened up significantly over time, fraudsters have found it increasingly difficult to hack merchant systems; as a result, fraudsters have had to resort to other methods, like phishing. Phishing is a form of cyber fraud that involves tricking innocent victims into providing their credit or debit card details without their knowledge – criminals then use this data for various crimes.

Criminals typically acquire consumers’ CVV2 codes by installing small machines at credit card point-of-sale terminals like those found at gas stations, recording magnetic stripe data from credit cards before transmitting it online for verification by payment processors. Once obtained, criminals use these CVV2 codes fraudulently at both online and offline businesses (POS terminals included).

Since the EMV liability shift, retailers are asking fewer consumers for CVV2 numbers; however, this doesn’t ensure complete consumer security; it is still wise to review your financial statements regularly and report any suspicious activity immediately to your bank. Furthermore, make sure to choose strong passwords and utilize two-factor authentication wherever possible.

Law enforcement agencies have taken notice of the illegal activities conducted on platforms like Brians Club. Numerous arrests have been made and authorities are actively working towards dismantling its infrastructure.


Fraudsters use Fullz (full information packages) for various criminal activities, including affiliate fraud (match betting and other gambling), money laundering and financial fraud. Fullz contains personal details about victims such as full name, date of birth, address, credit card numbers and other sensitive data that is obtained via various methods – data breaches, malware attacks or hacking of endpoint devices such as computers or mobile phones are just some examples of how criminals obtain Fullz packages.

Fullz files containing more information tend to fetch higher prices on underground markets, providing cybercriminals with a steady income source from selling stolen credentials to victim scams.

The black market has earned itself an unrivalled reputation among carding circles for offering high-quality stolen data and new exploits on an almost daily basis. This attracts carders seeking fraudulent credit card information. Keeping current is essential to its lasting allure as an underworld marketplace.

Additionally, the market’s involvement in several high-profile data breaches has further elevated its profile and attracted law enforcement agencies to it. With its dynamic nature, black markets provide criminals with fresh exploits and stolen credentials at their convenience.

Cybercriminals use fullz to facilitate illicit activities of all sorts, making businesses of all sizes vulnerable to falling prey to fraud and in need of an effective fraud prevention strategy. Businesses should consult a specialist in fraud fighting and cybersecurity in order to understand how best to defend themselves from the risks posed by fullz credentials.


Although cybercriminals continue to sell stolen credit card data on the dark web, consumers can take steps to safeguard themselves. Review your bank and credit card statements regularly in order to detect unwarranted charges that might indicate criminal use of the cards and prevent criminals from using your cards for illicit purchases.

Consumers should also use credit-freezing tools provided by their credit card issuer. These services go further than card locks available through credit bureaus by restricting access to their report, making it harder for identity thieves to open new accounts in their name.

BriansClub provides threat actors with access to stolen financial data for sale, making it possible for them to carry out various illicit activities like hacking and point-of-sale fraud. With its user-friendly interface and tools like validity checkers available on site, anyone with a computer can buy and sell stolen information easily through BriansClub.

Dark web marketplaces such as briansclub cm can have devastating repercussions for businesses and their consumers alike. By creating an underground economy, increasing fraud risk, and undermining global trust in online transactions – not to mention financial losses for both parties involved as well as harm to customers’ credit scores – dark web marketplaces like this one can prove harmful both financially and morally.

Law enforcement agencies have increased efforts against this marketplace, yet its popularity remains resilient. Even its name, which pays tribute to cybersecurity journalist Brian Krebs, adds an ironic note; indeed, its login screen now features Krebs’s likeness as part of its branding, blurring the distinction between cybercrime and cyberculture.
