moubik Posted January 29, 2008 Report Posted January 29, 2008 -------------------------------------------------------Greetz to kw3rln, nemessis, slick, flama, zbenghttp://rstcenter.com - Romanian Security Team-------------------------------------------------------Tor - un proxy pe care toata lumea ar trebui sa-l cunoascaCreaza chain proxy prin care poti sa navighezi pe net.Recomand folosirea lui cu firefox + torbutton addon.Poti sa aflii daca cineva iti navigheaza siteul cu tor ?Se poate.Tor blocheaza anumite requesturi. De exemplu daca ai tor activat si accesezi http://adrieu.org/Fpoll/poll.phpApare mesajulPrivoxy blocked [url]http://adrieu.org/Fpoll/poll.php[/url].See why or go there anyway.Unde textul "go there anyway" este linkat catre http://adrieu.org/PRIVOXY-FORCE/Fpoll/poll.phpPRIVOXY-FORCE - acest string ce este inclus in requestul GET forteaza proxy-ul sa se duca pe paginahttp://adrieu.org/Fpoll/poll.phpPractic stringul "PRIVOXY-FORCE" este sters din request.Nu se mai ofera nici un warning, pur si simplu se acceseaza.Ce s-ar intampla daca as crea acest director pe site-ul meu ?As putea asa sa aflu daca un user imi navigheaza site-ul prin Tor ?Am creat acest director, astfel:http://websecurity.ro/PRIVOXY-FORCE/Acum o sa adaug 2 fisiere cu exact acelasi nume in directoare diferite.Unul este in http://websecurity.ro/si celalalt inhttp://websecurity.ro/PRIVOXY-FORCE/Am creat pagina http://websecurity.ro/pocs/proxytest.html care contine:<iframe src="/PRIVOXY-FORCE/tortest.php" border="0" frameborder="0"></iframe>Fisierul http://websecurity.ro/PRIVOXY-FORCE/tortest.phpcontine:<div>[b]<font color="#ff0000">You are using Tor</font>[/b]</div>Iar http://websecurity.ro/tortest.php<div>[b]<font color="#00ff00">You are not using Tor</font>[/b]</div>Se intampla chestia asta:- daca nu ai tor activat vei accesa normalhttp://websecurity.ro/PRIVOXY-FORCE/tortest.php- daca ai tor activat in loc dehttp://websecurity.ro/PRIVOXY-FORCE/tortest.phpvei accesahttp://websecurity.ro/tortest.phpPentru ca el va interpreta "PRIVOXY-FORCE" ca pe o comanda si il va scoate din request-ul propriu-zisArticolul original si PoC:http://websecurity.ro/blog/2008/01/28/how-to-find-out-if-a-user-is-navigating-with-tor/ Quote
