I've not verified if this works in SEC, but you could maybe do a negative lookahead/behind
\.php\?id=[0-9A-Za-z]{8}(?!\.net|\.org) (?<!\.net|\.org)\S+\.php\?id=[0-9A-Za-z]{8} There may be a bit of a performance hit with using these though. Give them a try.

How do I create a regex with negation for SEC?
