content:"GET /?1 HTTP/1.1"; fast_pattern:only; is your best bet. You could break it out like this if you want: urilen:3; content:"GET"; http_method; content:"/?1"; http_uri; content:"HTTP/1.1"; "HTTP/1.1" isn't in a buffer, perhaps that's where you are getting the problem? -- Joel Esler Senior Research Engineer, VRT OpenSource Community Manager Sourcefire On Jun 25, 2013, at 12:57 PM, James Lay <jlay () slave-tothe-box net> wrote:
Hey all, So once in a while I see a compromised site that has something like the below after an initial redirect: GET /?1 HTTP/1.1 <snip> Host: 93.171.172.179 HTTP/1.1 302 Found <snip> LOCATION: http://93.171.172.179/?2 I'm trying to determine what's the best method for catching this. Here's what I think I understand: http_uri would match "?1", would http_raw_uri match "/?1" or even "/?1 HTTP/1.1"? I'd like to ideally match the entire "GET /?1 HTTP/1.1"..I've tried matching with http_header and http_raw_header, but I've not had any luck getting snort to fire on the pcap. I've hexed the ? and ? as well. Any assistance would help...thanks all!
