Check for credit card numbers


Searches for credit card numbers which may have been posted by users or otherwise accidentally released. DeepTrawl searches for four clusters of four numbers within three characters of each other. For example:


1652458621547584


5946 7424 9648 4521


4215x7854x6532x7854


Note: Checks the html in pages you own, doesn't check text in comments from 3rd party JavaScript driven comment systems such as disqus.
