Help > Trawling for credit card numbers

What does this trawl type find?

The release of internal employee or customer credit card numbers may leave your organisation open to possible law suits. This search checks for four clusters of four numbers within 3 characters of each other. For example:

• 1652458621547584
• 5946 7424 9648 4521
• 4215x7854x6532x7854

How to use this trawl type

You should make sure this trawl type is switched on. There should be a green tick next to this trawl type in the Trawl for... tab. If there is a red cross instead, click the cross to toggle the trawl type on.

How to solve the problems found

If you find what you suspect to be a credit card number, you should remove it immediately.
