The Student vs Hacker Security Showdown Rematch 83

monkeyboy44 writes "Following up on last year's entertaining hacker vs. student showdown, InformIT.com once again covered the annual Mid-Atlantic Regional Collegiate Cyber Defense Competition where college students are put to the test. During the three day event, small teams from eight of the areas colleges are handed insecure networks that they have to lockdown and keep running — all while a team of hackers attempt to gain access any way they can. To keep it interesting, the teams also had to perform various tasks, such as program web applications, install IDS systems and more — and if hacked, the US Secret Service was on hand to determine if there was enough data to start an investigation. Once again, the hackers dominated — but not without a few surprises."

      The problem with this is that they gave the teams securing the network 3 hours to prep.

      As someone who had to take over company's network, exactly what this exercise is meant to simulate, I can say it does take more than 3 hours to secure the services and appliances they were given without taking things offline. What's more, you usually don't have four seasoned hackers banging on your network's doorstep in your first three hours of employment. Also consider that most businesses don't keep a 10k record CC# database on a machine behind an unsecured perimeter appliance with a bunch of hokey other services running on them, accessible from outside the lan. The expectations of the whole process are a bit ridiculous to begin with, but if you gave them a day or so to secure their network and services, I'm sure they'd have done much better.

      Judging by the brief accounts of each teams actions, I'd guess that in more realistic scenarios they would make reasonably effective admins.

    Knowing how to secure both Linux and Windows, plus understanding Cisco firewall configurations (or Shorewall/iptables) -- not to mention having a firm grasp of web application security -- is not a realistic expectation of any newly graduated employee, much less a seasoned veteran.

    What? I'm guessing that maybe this is because a seasoned veteran would expect for the network to be maintained correctly? Especially the firewall?

    Really, this doesn't sound like a level playing field at all. My company support *three* services - IMap, HTTP, and ssh. We keep the programs that offer these services completely updated. There's not a lot to keeping those updated. There's one major player for ssh, two for web, and four or so for mail. Even the minor ones take less than an hour to figure out.
    We expect that the routers will handle almost everything else. Flaws coming out in IP stacks are a pretty major thing, and get fixed pretty quick, so it should mostly be a nonissue.

    If these guys only had to support features that people actually use and lock down everything else, things would be very different.

    Furthermore, they seemed to stress the "firewall" as if it was some sort of solution rather than just a roadbump as it is in reality. Disabling all blocking rules and simply serving as a router should have more than enough, since firewalls only ever provide the illusion of security anyway.

      If you put your servers physically in the hands of an attacker, there is nothing you can do to stop them quite by definition.

      Of course there is. You can encrypt drives, encrypt information, use secure Mobos, etc.

      As responsible for the integrity of your network, you're also responsible to let people know the level of physical security your network requires. As the article mentions, the servers were password-protected and expected to be secure. With physical access, the hackers got a suprisingly high level of penetration into the system without actually breaking it.

      It seems that the only way to win this competition on the defensive would have been to re-install the latest fedora core on all four machines, and setup services that you trust instead of MS services, then hunker down and physically guard the boxes.

      There was no way to "win" on the offensive. The offense wasn't being tested. The test was to see, basically, which group of sysadmins could outsurvive the rest. It wasn't an unfair competition between hackers and defenders. It was a task guaranteed to take out boxes, to see which team could best slow down the inevitable onslaught.

      In a production environment you don't necessarily get to set the policy on what servers you are running, and off of what boxes. You inherit a messed up pile of old systems, legacy software that nobody can update anymore, buggy drivers, and Windows users installing trojans and giving their passwords away to the first person who comes along with a YourCompanySecurity username on AIM. The fact that they took the end users out of the equation was a huge blessing to the sysadmins.

      Notice that they made damned sure that none of these computers were attached to the internet at the time of the task. These weren't the best of the best hackers the competition could find. These were a small pool of good hackers vs a small pool of sysadmins. If they had actually put these things on the internet, like production environments face every day, they would not have survived.

      Hence, the pre-installed keyloggers.

        Just to point out two things you said:

        Of course there is. You can encrypt drives, encrypt information, use secure Mobos, etc.

        In a production environment you don't necessarily get to set the policy on what servers you are running, and off of what boxes.

        Those two assumptions are somewhat conflicting I would say.

        On the first point
        The performance tradeoff for encrypted filesystems is seldom worth it on servers when you can physically secure them fairly trivially. If your building is regularly invaded, you have bigger problems. In any case, even if you can stop data loss with disk encryption, the guy could just take a hammer to your server and cause a DoS at the very least, and there is nothing you can do if you allow him physical access.

        On the second point: if you are such a low level peon in the a company that you are forced to accept bug ridden systems, then security is a forgone conclusion. Heck- acheiving it might compromise job security. I might suggest looking for a better job. Instead, if you are in a position to offer "services" to the company, such as email, DNS, or NAS then YOU (The IT dept) get to decide how to provide them, and then you can make decisions with security in mind. Before we get too separated from reality, we have to remember that the point of computers is to offer data services to the users, not to offer brand names. The rest of the company shouldnt even have to know whats behind the curtain, just that everything is up and running smoothly.

        Being asked to secure pre-owned windows servers is like being asked to levitate. Just give it up and re-install something else. The entirety of the O/S is analogous to trojan horse malware to start with, being that you do not get the source code. Trying to hold back the tide with a spoon and a colander is not my idea of security.

        It was a task guaranteed to take out boxes, to see which team could best slow down the inevitable onslaught.

        That would be uninteresting. Why even try.
        I think it should be not only possible, but fairly easy to setup a network that would provide service and not be penetratable over the network. You could even go for extra points by detecting unwanted probing or intrusions and blackholing the attacker's traffic so that you don't even suffer from a degradation of service. But assuming you will
        lose is the wrong mindset, imo. You have to play to win.

      • If you put your servers physically in the hands of an attacker, there is nothing you can do to stop them quite by definition.

        Of course there is. You can encrypt drives, encrypt information, use secure Mobos, etc.

        Eh?

        Seriously... I've never heard of a "secure mobo" in a production server - ever. Sure, you can password-protect the BIOS, rig up the handy physical intrusion alarm on the box (if there is one) and whatnot... but, umm, I don't see that as fitting your definition as used.

        Encrypted drives? Cool... until you have to restore the things from backup a couple of years later and no one has the password, because the admin who installed it never wrote it down anywhere, and he left the company a long time ago.

    It takes significant experience to walk into a network blind and secure it in hours. I have 2 decades of experience, and I've walked into places where it took days just to figure out w.t.f. they're running. It would take a day or more to figure out what all is going on in the network in my house -- and there's only 4 computers on at the moment.

    And if you're dealing with Windows(tm), it can take hours to download and install all the freakin' patches. (unless you happen to wander around with a fully populated WSUS/SMS server.)

    Elite Network Counter Strike Force pwn Teens
    (translated version)

    In the annual Mid-Atlantic Regional Collegiate Cyber Defense Competition (CCDC), held at a secret location, a Network Counter Strike Force Team, consisting of seasoned veterans from several security technology firms and academia, PWNed several teams of IT students in a stunning display of 1337-ness.
    In summary, the students are handed a small network with various services, most of which are outdated, vulnerable, and pre-exploited (rigged).
    They, the students, then, have a few hours to get everything patched and secure, at which point the RED Team (a.k.a. the haxorz) are set loose to pwn them all.
    However, as IT professionals know very well, it isn't just the hacker you have to deal with!

    The Secret Service was on hand to make sure the competition went a lot like last year, as well as many other unplanned events ("interviews"). Welcome to the "Real World" -- CCDC style!!!

    The students' goal: lock down rigged Windows and Linux systems and secure their networks. The Hackers' goal: to pwn the students' networks, steal important data and embarrass them in front of their Mothers.
    Hylas Ipsum (not_hylas( )) read about the 2007 real-world competition and reported on the event from the perspectives of Slashdotters and first year Umpires everywhere.

    Last Year's Event

    This was the second year for the CCDC. I wasn't invited to last year's event, like this year, which turned out to be a very amusing experience for the haxorz. As with any first time adventures, unexpected "anomalies" played a very big role in the outcome of the event.
    Despite minor hiccups, the Secret Service benefited most by walking away with all the chicks.

    This Year

    Prior to attending the 2007 event, we were fairly certain the RED Team was going to have a more difficult time gaining access to the students systems.
    Perhaps the most amusing and educational aspect to this years Mid-Atlantic CCDC was how the RED Team managed to surprise everyone involved by cheating again, with no one saying a thing. Since the Prize Cups' disappearance the night before, this contest was for "sport".
    With the air of sportsmanship renewed, the game was afoot.

    As previously mentioned, each network contained a wide range of operating systems and services. In summary, the core network contained three computers:

    A Windows 2003 computer running an Exchange Server, telnet, DNS, and Active Directory
    A Fedora Core 4 server on a DMZ running Apache, telnet, PHP, MySQL, and osCommerce
    A Windows XP workstation running syslog, VNC and telnet
    In addition, two of the teams had a PIX firewall w/telnet and the other six had a Linux-based system running telnet on Smoothwall.

    Prior to the physical intrusion, the RED Team had the most success by exploiting default configurations and default accounts. Once they were let loose, the team members quickly found and "pwned" routers, osCommerce sites, and Linux servers simply because the systems were still using default accounts. Unfortunately, this is a "real world" problem that has turned more than one company into a victim. Or to put it another way, why attempt to locate and exploit a DCOMRPC vulnerability when the password to the Administrator account is blank!
    Why indeed?
    The RED Team then commenced to "trash talking" the students, seeing blood in the water.
    All this said, the event is much more than just a competition. It is a test of how well a person can perform under serious pressure. In fact, there was an unofficial "bonus" to the first hacker who could make a student cry.

    Default configurations and accounts were bound to be located and fixed within minutes. The RED Team would not be able to simply walk in, connect to a system, and login. However, CCDC predicted this and provided a few "unknowns" to assist the red team with their work.

    Since the "corporate network" was not truly connected to the internet for "security reasons", all patches and updates ha

    I was a member of one of the (losing) student teams.

    First, none of the members of my team are majors in network security (just "IT"), linux gerus, and we did not recieve any advice from the previous team that went last year (what fags).

    Second, two of the four boxes were Linux. Three monitors. The firewall box and the windows xp workstation box was KVM'd together.
    8 people trying to work on 3 machines = not cool.

    Third, oh god all of the systems were basically pre-fucked up. Rootkit/keyloggers on the 2003 server box, there was a wireless access point that was PLUGGED INTO our switch, broadcasting all internal traffic to the red team and allowing them DIRECT access to the internal network.

    Fourth, it wasn't clear to my team that we had to have THREE external IP addresses mapped to THREE internal IP addresses, so our firewall/router solution didn't work at all. Business inject on the first day? ha? none of the e-mails could get to us because they were sending it to another ip! At the end of day 1, they also said that they would reimage the firewall box to Fedora Core 4 and give us control over it. So, everyone crammed as much about configuring fedora core 4 and learning iptables... we walk in day 2 and the guy says that he locked us out of our firewall box and that we aren't allowed to change it. (because 7/8 teams fucked up the firewall on the first day). Awesome, three direct ip mapping into our private network!

    Fifth, there was a misunderstanding about what kinds of software we could use. We thought we were able to use ANY (non-pirated) software that was available on the Internet, including free trials. Turns out, we were only allowed to use commercial software ONLY if it was released as a beta version and had the appropriate enterprise use license. Hurray windows firewall? It's not like we could download zone-alarm.

    Sixth, there was just too much stuff that was already on the machines that no one on my team had any experience with. osCommerce? hah.

    Seventh, 70% of all the business injects are related to the website. When the red team broke into our Linux (fedora core 4) box, they completely fucked Apache and MySQL up (how to backup Linux? nothing to backup TO). So much for all those business injects.

    Eighth, we only had one laptop to use to download stuff from the Internet or to research free software alternatives. Granted, our team probably needed more people that knew how to use Linux, but still...

    Ninth, the network diagram was incorrect. How the hell do they expect us to configure a router if they provide the wrong DNS/default gateway information?

    Yeah, we got owned hard... but there's also the saying... you learn from your mistakes... I believe I learned more in those 3 days then my entire 3 and 1/2 years in my university.
