Blackhat Day 1 - My Personal Recap

Par MX Logic ThreatBlog
Le [2009-07-30] à 12:23:17



Présentation : Greetings from Las Vegas and the Blackhat Conference. As I mulled over what I was going to write, I realized that if I said everything that I wanted to say I would be an epic post and that most people probably wouldn't make it all the way through. So, I'll try to keep my editorials brief and to the point as I review Day 1 at Blackhat. The morning started with a keynote by Douglas Merrill, formerly of Google and several other places, but he is mostly likely most known for his work at Google . This was a great talk where he said, among other things, that we are doing security incorrectly. In large part I agree with him. This is generally because it appears that the goals of the security program from the Information Security Officer's perspective and the CEO are very different. We already know that support from executive management is critical to the success of your security program, but I don't think we are doing enough of is making sure those goals are aligned. That comes down to better coordination between the security officer and the CEO. The CEO might fully support the work that you are doing, but you need to be sure your intentions are aligned otherwise you might be focusing on the wrong thing, which could end you up in hot water should an event happen which the CEO thought you had well in hand. There were many other things that he covered as well, but I want to move on to the rest of the day. The next session that I attended was one on Router exploitation. This was also a very interesting talk because the presenter segregated his talk into different ranges part of the talk was at a level more for the managerial types in the room and the other was geared more toward the hardcore assembly programmers in the room and some in between . The primary focus of this presentation was on the ranges of exploitability is that a word between different types of routers. He zeroed in on Cisco's IOS, mostly because they manufacture the most widely used routers on the internet. Also discussed were the difficulties in exploiting Cisco's routers. Why Because their code is so secure that it is nearly unbreakable No. Because of the different variations in their build process. According to Cisco's feature navigator as of June 2009 they have over 272k different builds of their IOS software, which probably contain about as many different memory and heap layouts. These different memory layouts make exploiting a router very difficult because you have to write your shellcode based on a memory layout which is entirely variable based on who you are targeting. He also discussed how to potentially exploit a router using ROMMON ROM Monitor and some of the challenges associated with that type of hack as well. Next I attended a presentation on fighting Russian cyber crime mobsters. This was a very interesting talk with a lot of historical references and timelines primarily with respect to the Dark Market FBI sting headed up by Agent Keith Mularski, who was one of the folks speaking. He gave detailed accounts of his undercover operation and how well crafted it was. It was so well done that people in his own agency couldn't figure out he was the one participating in the sting. He also gave accounts of how he earned the trust of the top members of Dark Market, even to the point of getting them to move the Dark Market forums to FBI servers of course the Dark Market folks didn't know they were FBI servers when the site was under a DDoS attack. Very entertaining. The next session was about cross site scripting XSS and how to craft XSS that will bypass some of the known filters out there like Noscript, IE 8's built-in functionality, PHP-IDS, and mod_security. I learned a few new XSS tricks that I am looking forward to bringing back and playing with. The moral of this talk was that even though there are ways to construct XSS attacks that can bypass these filters, overall they do a pretty good job save for mod_security which you should steer clear of of detecting the common attacks and even do well at picking off the not so common ones. The biggest issue with mod_security is that its filtering looks for specific keywords and doesn't handle many different encodings so it is easily fooled . The next talk was about the underground economy. Although I found this talk very interesting and full of facts, I don't necessarily agree with some of the statements that were made. One of their overriding assertions during this talk was that spammers aren't making very much money. The quote was that If anybody can do it, everybody does, and nobody makes any money. I believe that this assertion largely depends on what part of the spammer food chain you are looking at. At the bottom rung of the food chain you have the grunts, the mules, the infantry....the ones who are most at risk of being caught. These are generally the folks who are running the drop accounts, the accounts that are used to move money from one account to the next. These folks are the most expendable and make a small wage for their time. Consider them the burger flippers and french fry makers of the organization no offense intended to burger flippers and french fry makers . As you move up the food chain you are dealing with people who are generally less visible to the operation and are also pulling in more money. Continue to move up the chain until you get to the guy at the top. Now, if you are playing off of sheer percentages, yes, a good percentage of the operation, the front line folks, aren't making that much money. The reality, however is that if spammers weren't making much money they wouldn't have the motivation to continue doing it. It is a financially motivated economy and the only reason these guys stay in the game is because they can make money, lots of it. They did make one point which I thought carried a lot of weight, and that was the reasoning behind why more banks have not implemented something the security community has been asking for two factor authentication. Some banks have implemented some cosmetic features like on-screen keyboards and SiteKeys, but the reality according to their figures is that banks lose an average of 34 cents per year per person. The average support phone call that gets through to a person is about 10 call. So, even if 10pourcents of a bank's customers made one phone call to the bank on a support issue, that still dwarfs the losses from phishing. So, at the end of the day the cost benefit analysis of whether or not to implement two-factor authentication falls on the no side of the fence. The last talk I attended today was one called Internet Special Ops Stalking Badness Through Data Mining . This talk started off kind of rough. Paul Vixie started his portion of the presentation by apologizing doesn't he know this is one of the things that you NEVER do during a presentation to the audience because the slides he was going to present were probably too high level for the audience another one of the things you NEVER do. You must know your audience . He said he was expecting more people in suits than technical folks. I am assuming he has spoken at Blackhat before Anyway, the other two presenters were decent, talking about Conficker and how to correlate different disparate data points to put together a story. I have to admit though that because of how this presentation started, this was the one that I was most underwhelmed with. It was also the end of a long, learning filled day so you could also accuse me of being a bit apathetic at that point and I wouldn't argue with you about that point. I also attended Johnny Long's talk about Hackers for Charity where he also talked about his story from where he began to how he got to the Internet Rockstar status he currently has. This guy is laugh out loud funny. I know quite a few people who make me laugh pretty hard, but I can usually control it to a low roar. This guy made you laugh out loud to where you are completely unable to keep yourself from doing it. In addition to Hackers for Charity being a great organization, he had a great message as well. That message was that in the security community we have great power and knowledge. We should use that great power and knowledge to make sure we are doing things that are bigger than ourselves. Don't focus on personal gains. Focus on how you can help other people. A great message that we should all live by regardless of our professions. So, that is my wrap up from Day 1 at Blackhat. Overall a great day and I am looking forward to tomorrow being just as fruitful.
