Most of the enterprises we work with employ VPN clients that use compulsory tunnels. Once the VPN client connects, all other traffic in and out of the computer is blocked. This, by the way, is also our best practice recommendation. There are of course plenty of companies who don't follow this approach. To answer your question, no, I don't know of a specific incident. irwin ------ Irwin Lazar Practice Manager, Burton Group www.burtongroup.com <http://www.burtongroup.com> ilazarat_private <mailto:ilazarat_private> Office: 703-742-9659 Cell: 703-402-4119 "DrivingNetworkEvolution" -----Original Message----- From: Jim MacLeod [mailto:jmacleodat_private] Sent: Wednesday, October 09, 2002 5:21 PM To: firewall-wizardsat_private Subject: [fw-wiz] Tunnel intruder There's a lot of FUD being touted by firewall vendors about the possibility of a home computer being hacked, then the attacker using that computer's VPN connection to the office to break into the company network. I can see this as a possibility and realize that we could easily get into an extended discussion of the probability/impossibility/inevitability of it occurring. I personally want to avoid speculation. Does anybody know of an actual incident where this attack was used, successfully or not?
