Credit card fraud is becoming more organized and easier for criminals to carry out. Cybersecurity researchers at Rapid7 say this is due to a growing underground system called Carding-as-a-Service (CaaS).
Instead of random online scams, criminals now use platforms that work like normal online shops. These illegal marketplaces sell stolen credit card details along with personal information such as names, addresses, and ID data (often called “fullz”). They also provide tools to check if cards are still active, offer refunds for invalid data, and even give customer support to buyers.
The stolen data comes from different sources, including fake emails and websites (phishing), devices that secretly copy card details at ATMs or payment terminals, and malware that steals information from infected computers.
Well-known underground platforms like Findsome and UltimateShop allow criminals to search for cards by country, bank, or card type. This makes it easier for them to target specific victims.
Because criminals often get full personal profiles, the harm goes beyond stolen money. Victims can suffer identity theft, hacked accounts, and long-term financial problems.
Security experts warn that businesses must take stronger steps to protect data. This includes using multi-factor authentication, keeping systems updated, and monitoring the dark web to spot leaked information early.
Cybercrime is no longer a small-scale activity. It is now well-organized, business-like, and global. Both companies and everyday users must stay alert and improve their digital security to stay safe.
