A hacker gang known as “Keeper” established an interconnected network to steal credit card data from over 570 e-commerce sites. Since 2017, they have profited around $7 million in crypto by selling card information through the dark web.
According to a July 7 study by threat intelligence firm, Gemini Advisory, the hacker group managed to create 64 attacker domains and 73 exfiltration domains. These domains were used to retrieve user credit card data from numerous e-commerce sites located across 55 countries.
