SA Regex expression

[NM]

I am trying to create a regex to filter urls but it is not working. I am trying to apply the following regex:

/\w{20}\./g

This is to show urls that have 20 alphanumeric characters before the ".", i.e. trying to find long urls in a hope to identify DGA created urls. However it is not working when I put it as a search criteria.

I have run tests with lower numbers to test it but it still returns no results even when it should. Please help to determine why it is not working.

Hello All

I managed to find the answer. In case anyone is interested, SA uses the Perl regex syntax.

You have to enter the regex without the "/.../" slashes. The regex that helped me in the end was:

\/\/[^w][a-z0-9]{13}

This will hit on something like the following (bold):
