Reporters At Black Hat Get Bounced For Hacking

rickb928 and several others have written to inform us that three reporters for the French publication "Global Security Magazine" were booted out of the Black Hat convention for uncovering the login information of other reporters. Quoting the AP: "The separate, wired Internet connections set up for reporters are supposed to be off-limits to hacking and the Wall of Sheep. Even so reporters who didn't take the extra step and log onto the Internet through an additional secure connection like a virtual private network, risked having their data exposed to colleagues sitting just feet away. It didn't appear to be a complicated hack. The network was working properly, but it wasn't set up to shield each journalist's computer from one another."

      You'd think the organizers of the Black Hat convention could properly secure a wired network.

      Which they did. They just didn't secure it from the other journalists.

      Consider that it is actually impossible to do so, and allow journalists to bring their own laptops. The best you can do is secure a network, not secure the computers on the network, without insisting on admining each such computer -- think Mordac-style.

      I'd lay the blame with the Black Hat organizers.

      By properly laying the wiring, they could ensure that you could not set-up such a passive filter. Each group of journalists could have had their own separate connection to a properly configured router - that way, if you wanted to snoop on another journalists traffic, you would have to walk over to their table and jack into their Ethernet connectors, which is significantly mitigates the severity of the problem.

      Another thing - there's any number of industry-standard authentication & encryption systems out there. IPSEC, 802.1X, Radius, etc. The organizers were just lazy and decided that they would simply call it a trusted system and not actually bother securing it.

      I'm sorry, but this demonstrates hypocrisy on the part of the organizers. They criticize (rightly) businesses for being lazy when it comes to security, yet turn around and do the same thing themselves.

When you're in a conference about hacking and computer security, you should expect that your computer should be broken into. All that aside, if the rules specifically stated that the wired networks were for reporter use only, and were not to be used for hacking ("separate, wired Internet connections set up for reporters are supposed to be off-limits to hacking and the Wall of Sheep" according to the article), then the reporters who used it to get login credentials and then turned them in despite the rule about no hacking and no Wall of Sheep are stupid and deserved to get kicked out.

      With a suitable access lists, and each Journalist's PC plugged into their own port on a Layer 3 switch and everyone NAT'ed, no they would have no normal means of using their legitimate connection to attack another journalist's PC.

      For instance, local PC to gateway might be allowed, but there would be no method allowed to have PC to PC or broadcast traffic. That's the ideal scenario.

      E.g. It would be essentially be an internet-only connection, no LAN whatsoever.

      Actually, the ideal scenario is the journalist uses a dedicated end-to-end encryption over a VPN, and their PC is config'ed to refuse all other traffic. (So any 'attack' would have to originate on the home network)

      802.1X auth is a good standard and all, but it's use is unrealistic -- many journalists would not understand how to connect their laptop.

      Actually, isolating each journalist into their own ethernet broadcast domain is probably unlikely -- due to the massive number of journalists at events like blackhat, and resulting burden in defining a unique ip network for each one.

      Port security (limit of one active MAC address per port), and DHCP+ARP inspection + filtering (to protect against ARP hijacking or fake DHCP server traffic) are more realistic security measures in an environment like this, and very basic.

      The attempted connection of a second PC to a port while another PC is recently active _should_ immediately set off alarms.

      Limit of number of active MAC addresses also makes it hard for a bad journalist from attempting to sniff by sending blank frames with spoofed victims' MAC address as source (to make the switch forward to the attacker).

      It's not surprising that blackhat didn't implement these types of security measures -- most network security features are rarely implemented, even on 'secure' networks.

      Security of such ad-hoc setups is more of an afterthought.

      I don't understand this very well, so someone who does please chime in.

      Switches use your ethernet card's MAC address (not IP) to know how to route ethernet frames on across the switch. It knows that MAC AB:CD:EF:etc is on port 1, and 12:34:56:etc is on port 2. Because you can daisy chain switches, it actually has to remember a many MACs to 1 port sort of mapping.

      Switches can only remember a finite number of MAC addresses, so if you overflow the memory of the switch with bogus MAC addresses, it fails over to hub mode and just broadcasts all the packets to all the ports. It's not pretty, and would cause the network to get slower, but at least it would continue to work.

      As I can't see hubs being used at a Black Hat conference, I'd guess this is the sort of thing the reporters did. I'm sure there's a name for it... probably "ARP Cache Smashing" or something, but I don't know it.

      "ARP poisioning" is what it's called, and your explaination sums it up pretty well. If the other side of a port is claiming to have enough MAC addresses reachable by it the cache will fill and the switch will start over with a blank cache which renders it into a hub until it learns what's really where, then gets poisioned again, rinse, wash, repeat.

      Dumb switches will fall for this trick and have no way for anybody to notice, smarter switches will log this and let the admin know there's more than one MAC address being reported on a port... you just trace to who's on the other end of the report and you've busted them.

    It's a common misconception that switches prevent snooping. Switches are *not* security devices, they are an performance optimization. As such, they mostly "fail open".

    If you flood the switch with many different MAC addresses, such that its internal ethernet routing table fills up, it will usually simply direct *all* traffic to your port, rather than potentially incorrectly dropping some traffic you should have received.
