actually, rawbody won't help you.. those characters are decoded even in "rawbody" type rules...


the only differences between rawbody and body are that rawbody retains HTML tags and line-breaks.

base64, QP and other character decoding filters are still applied to rawbody rules.

Is there a simple test for this sort of obfuscation?

Not really, although you can create tests resistant to a single-character mangling by using a . or \w wildcard.


A trick in SA rules?

None yet, although many have suggested enhancements to the code to do things like "deobfuscated_body" rules, etc.
