Skimming was traditionally the term given to cash machine fraud – where criminals fit ATMs with devices that can read credit cards. However, in the online version, they target checkout pages instead

Thousands of online shoppers have potentially had their bank details “skimmed” on the checkout page of small business websites, GCHQ has warned.
The agency’s National Cyber Security Centre (NCSC), said it had uncovered more than 4,000 incidents where business websites have been unknowingly leaking customers’ financial details to hackers.
The NCSC warned that the scam was happening mainly on the websites of smaller businesses where cyber criminals were able to exploit “vulnerabilities” in the software.
