From: se_cur_ity at hotmail.com (morning_wood) Subject: NAT router inbound network traffic subversion scenario... NAT client browses web... NAT client initates a HTTP request to do this... ROUTER returns the request to NAT client... ( normal activity ) attacker website exploits client browser... exploit drops and executes "badfile.exe" "badfile.exe" hooks iexplore.exe... "badfile.exe" is 'reverse connecting trojan'... "badfile.exe" initiates a HTTP request to do this... attacker's "badfile.exe"' 'client' is waiting with a HTTP server... the new hooked browser initiates a HTTP request to the attacker. NAT client is now connected to the attacker through the ROUTER ( kinda like browsing the web huh? ) attacker now has unrestricted packet via the NAT client, that is where ??? BEHIND YOUR ROUTER atacker now can do a he wishes to the rest of your network ( GAME OVER ) Cheers, m.w
