Splunk Search

How to write the regex with mode=sed in a search to mask part of credit card numbers?

New Member

I need help with one particular search for masking credit card numbers, but with this output 22222#######2222. I know how to manage search for ############2222, but don't know how to mask between numbers.

Thanks, cheers

Please write your search (for masking like ############2222) - we could modify it

mod=sed "s/(\\d{12})/############/g"

Something like mod=sed "s/(\\d{5})(\\d{7})(\\d{4})/\\1############\\3/g"

Will rewrite first match, write hashes and third match

edited; I forgot about escaping \
