Here's an example of malicious code:
The researchers said that hackers they use reputable names like Google, so visitors think that sites are safe. But they do not pay attention to the fact that there is one domain differentiation, which indicates that it is a malicious site.
Researchers have discovered that the particular skimmer is similar to others that are circulating and storing data, imported, as well as drop-down menu options.
However, skimmer checks if developer tools are used either in Google Chrome or in Mozilla Firefox. If used, it will not attempt to steal any information to avoid detection.
If no developer tools are found, they steal information and send them to a remote one server.
