Over 4,000 online retailers have been warned that their websites had been hacked by cyber criminals trying to steal payment information and other personal information from customers.
In total, the National Cyber Security Centre (NCSC) has identified a total of 4,151 retailers that had been compromised by hackers attempting to exploit vulnerabilities on checkout pages to divert payments and steal details. They alerted the retailers to the breaches over the past 18 months.
The majority of the online shops that cyber criminals exploited for payment-skimming attacks were compromised by known vulnerabilities in e-commerce platform Magento. Most of those affected and alerted to the compromises and vulnerabilities are small and medium-sized businesses.
