Peter_Smith Posted November 21, 2006 Report Share Posted November 21, 2006 I am concerned about possible exploits employing Java/Javascript to capture my real IP. If one employs a proxy (one or more in a chain), to my mind even if these proxies are anonymous and only reveal their address to the target server, and not my real IP, there seems to be a nagging thought in my mind. What if sites such as Hotmail/MSN which insist you use Javascript could run a java program which effectively calls the ipconfig/ifconfig routine (on W32 or *nix/Linux) and they grab the output of this routine (or an equivalent written in javascript or other scripting language) and filter out the real local IP of the workstation? That would effectively make the use of the proxy useles!!! Does anyone have any insight into this area, could anyone confirm if that is possible and if so if they know of such scripts? Similarly, closed-source programs such as skype/ICQ/MSN could be running local scripts to grab the local IP address on the workstation they are running on and forward it to their respective loging servers. Does anyone know if this is the case with any of the IM programs mentioned in this post (perhaps there are some developers who have worked on such programs and may have insider info on such matters).If what I suspect is true, anyway to stop such scripts acquiring the local real IP whilst maintaing operation with the service ?Does anyone have any tips on how to monitor the Java/Javascript activities when using Firefox, IE, Opera under W32 and Linux? I know in Firefox you can switch off scripts using a plugin and there is Toos|Javascript console, any guidance for getting the best out of this console or other similar utility would be greatly appreciated.TIA.

Scarecrow Man Posted November 22, 2006 Report Share Posted November 22, 2006 Your ISP will be able to tell you more about how your IP address is used. It is usually outlined in your Licence Agreement. You should review this and also contact your ISP for more information. Link to comment Share on other sites More sharing options...
Mike567 Posted January 2, 2008 Report Share Posted January 2, 2008 Scarecrow was correct in what he is saying, the basis behind his reply is even if you use a proxy you can still be tracked down.as the ISP is tracking all that you are doing, and can link it to and 'bad' activitys going on.you can defeat javascript very easily using greasemonkey, if you haven't worked that out already I doubt you can even complain about scarecrows reply.Why not show some respect for other people and give a good reason why their reply was incorrect.

ɹəuəllıʍ ʇɐb Posted January 3, 2008 Report Share Posted January 3, 2008 Why not show some respect for other people and give a good reason why their reply was incorrect.Was there some post that got deleted somehow? I cannot see what you are referring to.As for the original post; what is the reason that you are so desperately tryin to hide your IP address?

-pops- Posted January 3, 2008 Report Share Posted January 3, 2008 There was an extremely insulting and unjustified post about Scarecrow Man which I deleted, thus making Mike's reply somewhat meaningless. I also banned the writer.Considering this thread was started more than a year ago, I don't think it worth continuing with it. Link to comment Share on other sites More sharing options...
