Black Hat USA, DEFCON 18 Pre-Event Briefing

On my way to Las Vegas, NV for Black Hat 2010 and DEFCON 18. I barely got on the flight, and that’s with a confirmed reservation. Apparently Delta does this new thing wherein anyone who books late or after 60-70% of the flight is booked doesn’t get a seat assignment. Instead you have to wait for your initials to show up on a TV screen at the gate. I guess it is a lot like the lottery. I was essentially the last person to board, and a nice couple gave me the window seat. I had a few minutes to start this post on my iPad, which was handy.

Thankfully, this year, I will be attending on behalf of my company and better yet, for real business. As an IS LDP, I’ve managed to land a great rotation within the information security department. I’m primarily working on educating developers on how to write secure code, tools they can use, and implementing new process milestones to ensure that everything is coded securely for that specific case.

Unfortunately, a lot of what we need to cover hasn’t been revealed yet: this year’s exploits. Being in attendance for Black Hat and DEFCON is the best way to get informed, meet people who know what we’re up against, and really understand what we’re doing. That said, I had planned on making the trip to Vegas already, as I did last year for DEFCON. Something about the community at the DC events is just amazing. Your concerns, thoughts, and ideas suddenly don’t fall on deaf ears. Why? Because every attendee knows how deep the rabbit hole goes.

I’m very excited about the talks this year. The residential router pwnage is going to be a popular talk I think, as well as the ATM jack potting. I’ve heard there will be a GSM interception demo at one of the talks, which will be hilarious if it works, so I’ll have to remember to stay off my phone during that one. For work, I’ll be attending the web application and coding talks; especially the Blitzableiter release, as we really need information on secure Flash and ActionScript coding.

What else is there? Oh right, the rest of DEFCON… I’m hoping to get into a few parties this year. I don’t drink, and try not to get into related predicaments, but the opportunity cost is far too great to pass up. The people you can meet just by hanging around the smoking area, even if like me, you don’t smoke, is awesome. Last year I met am ex-Air Force cyber warfare guy, a crazy German with a gambling problem, and a red team teacher and mentor. Okay, that last guy was drunk, but he turned out to be telling the truth and had some very good stories.

The plan for this year? Shed my newbie status and get out there.

Smurfing: Security is Amusing

Today in my CIS4361 Secure Operating Systems class I was drifting off as the professor was doing a quick review of filesystem attacks when I heard the strangest phrase since the BouncyCastle provider for JCE: Smurfing. Apparently this smurfing, as it were, is when an ICMP echo packet is spoofed from the target’s IP address to a router, called the smurf amplifier, which then sends the request to all of the nodes attached to it who then send ICMP echo reply packets to the target. Essentially, this inundates the router and target with echo reply packets and should lead to all out network outages. Pretty neat, and with a name like smurfing, it has to be good.

Secure Instant Messaging

It’s called ScatterChat by Hacktivismo/CDC. Very nice tool that uses the Gaim source along with the Tor network to route IM traffic as well as encrypt it using RSA key files. Very slick.

TOR Park – New Release April 19th, 2006

From TOR Park Website:

You may have heard about those heavily advertised second-rate software packages like Anonymizer, SafeSharing, InvisibleIP, SecretSurfer, etc. Well, not only do they charge you money and/or a subscription fee, but they are bloated and full of useless components. They also require an installation which leaves tracks on your computer. How is that anonymous? Try Torpark; its small, portable, clean, free of spyware/adware, and best of all its free of cost.

From TOR Official Website:

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.

A branch of the U.S. Navy uses Tor for open source intelligence gathering, and one of its teams used Tor while deployed in the Middle East recently. Law enforcement uses Tor for visiting or surveilling web sites without leaving government IP addresses in their web logs, and for security during sting operations.

Watch those keystrokes, you might get a felony.

Today on digg, there was an article about a “Deadly F5 Attack” at a highschool. Man, that’s sick. I guess if you wrote a script to maliciously infect a machine to execute F5 on every machine it might be deadly but no, guess what this kid did? He wrote on his blog and told all of his friends to go to the school’s website and hit F5. Now, what’s funny about this is:

  • It’s a kid’s blog. Seriously.
  • Who listened to this guy?
  • F5, what’s that do again? Refresh. On what systems?
  • Why do they run their webserver on the internal network?
  • Don’t they know they’re going to get dugg/slashdotted now?

So there you have it. Watch your keystrokes, or your next blog entry could be from jail. Lovely.
