Sniffer Fingerprinting

[PacketThirst]

Hey folks ! ..

I happened to use a sniffer for the first time a few hours ago.I just activated my Sniffer

and started surfing as usual.I found the following packet quite interesting ...



E¿N@/ŽÜ?’mÒÊXö…PÃ*â€*ÊÃ*#ÓoÒ¬PÞ2HTTP/1.1 304 Not Modified
Date: Sun, 19 Sep 2004 02:01:49 GMT
Server: Apache/1.3.29 (Unix) PHP/4.3.4
Connection: close
ETag: "6b5-154-3b50642e"



This is a packet from AO. I guess that the packet gives out the web server information as well

as its version number (Apache V1.3.29)!!.Isn't this really insecure ??. The stuff isn't even

encrpted !!.Isn't there someway to stop this ????

You could get the same info by doing a banner grab. Just telnet to port 80 ands hit enter twice. Some folks go to the trouble of masking what web server is being used, but most think it's not worth the bother.
