It might work assuming you're not hosting multiple websites off of one IP address (HTTP URL headers would be required them). I also would think the firewall doing the URL redirect to the monitoring server would be sending the octet version of the IP address, so it would just get changed back to a monitored IP anyway. -----Original Message----- From: Charles Hamby [mailto:fixer () gci net] Sent: Wednesday, February 25, 2004 7:15 PM To: McNutt, Jacob Cc: Kudakwashe Chafa-Govha; pen-test () securityfocus com Subject: Re: By passing surf control Have you tried checking to see if IP address obfuscation works? In case anyone's not familair with this... Using http://www.amazon.com as an example. If I wanted to go there but it was blocked, I would find out what the IP address of www.amazon.com is (say using ping). In this case it happens to be 207.171.181.16. I would then convert each octet into hex individually. (207 is CF, 171 is AB, 181 is B5 and 16 is 10) Then I would put CFABB510 into my calculator (Windows calculator works just fine for this, by the way) and conver it to decimal again. I would come up with 3484136720 I would open up my web browser and put in http://3484136720 and up comes Amazon.com. Charles Hamby McNutt, Jacob wrote:
SSH tunneling/port forwarding to a proxy might work if they have access to it. Also, we have a problem with AOL client browsers that can bypass Websense all together. -----Original Message----- From: Kudakwashe Chafa-Govha [mailto:KChafa-Govha () bankunitedfla com] Sent: Wednesday, February 25, 2004 3:04 PM To: pen-test () securityfocus com Subject: By passing surf control Hello Group, Does anyone have any information on how to by pass a web content filter? We use Surf Control to monitor and filter web content. However, I have one of my users who was able to by pass this. We tried using a proxy to by pass just for testing purposes but it did not work. I am still trying to figure out what other method he used to do so. If anyone has any information , it will be greatly appreciated.
