Data pattern to check 2 conditions on Credit Cards

MarcelST — Wed, 07 Dec 2016 14:42:40 GMT

Hi,

Let's say I want to create a Data Pattern to check 2 conditions on DLP:

1) Check Luhn number. This can easily be done by setting a weight in the "CC" field on a DLP Data Pattern.

2) Once the Luhn number checked, check if the first 7 numbers of the credit card matches some BIN codes of an specific Bank.

is that possible? I mean, the "2 conditions check". In order that the alert is only triggered when it satisfies both conditions.

Thanks!

If you know which BIN numbers you want to check you can simply create regex signatures to match these in a custom Data Pattern.

both will be checked at the same time however, you can't 'sequence' DLC profiles

You mean something like this?

Do you know if this condition is going to trigger 2 times for every CC matching both (the CC# luhn algorithm by Palo Alto and the custom Regex?
