  1. Pixel Perfect Timing Attacks on Ask Slashdot: Favorite Thing Out of This Year's Black Hat? · · Score: 1

    Easily one of the best technical talks I have ever seen; how timing attacks can be used to break the same origin policy and read the contents of a frame. This talk included demo's of an attacker site loading up a target site in a frame and reading the contents to grab the CSRF token. It was awesome. http://contextis.co.uk/files/Browser_Timing_Attacks.pdf

  2. Giant virtual bar on Study: Online Dating Makes People "Picky" and "Unrealistic" · · Score: 3, Interesting

    In my experience, the most popular dating sites (listed as type 1 in the article, like OKCupid and Match) are like giant bars. The women are hounded from all directions by men, and the men seem to have to fight to distinguish themselves. Every good friend I know that is female and on one of these sites is constantly bombarded and things quickly devolve into shallow initial impressions. I'm willing to bet most relationships started at bars are often shaky when things get real as well.

  3. A bit misleading ... on MI5 Website Breached By Hacker · · Score: 5, Informative

    I see this and think the word "Hacked" gets thrown around a bit too easily. This is an example of non-persistent (also referred to as reflected) cross site scripting. This means that in order to take advantage of it, they have to convince a target to visit their specially crafted link. To me, "Hacked" sort of implies "They got in!" or "Data was breached!" or other such bad things and that simply isn't the case here.

    So what does this type of XSS do? Mostly embarass people because defacement examples are posted to "look what I can do" forums (which is basically what happened). Think about the attack vector here, they have to get a victim to visit their specific url that includes their attack. How is that done? Malicious email, posting the link to some website or forum and hoping they find it and visit, embedding the link in other sites that have been hacked or something like a banner ad, or whatever. All of these involve the target going out of their way to visit this maliciously crafted url. When you consider that they could still do all these things without XSS and simply host malicious code themselves, all this reflected XSS is doing is making it a bit harder for an end user to spot that this is something non-standard and dangerous.

    Think of it this way, "With reflected XSS, I can send them a link, and if they visit it, I can do bad things to their computer!" but then again, you can do that without XSS too, it just isn't quite as effective. How many users are taking the time to carefully look at a link before clicking on it, checking to make sure it contains the domain name they expect and not just an IP address, or a domain name that is similar, but not quite right, etc. A user who is doing this sort of thing will more likely fall victim to this XSS attack, but most users, who don't scrutinize things at that level, were just as susceptible to a classic phishing/malicious linking attack anyways.

    Your second plothole isn't a plothole at all. Joker was taunting them, "I was here, clearly I couldn't have done this" while making it plain that he was responsible/involved. His "What time is it?" comment is followed by something about depending on the time they would be in one place or several. It's a very clear threat that they are in danger and time is sensitive. I think you are reading more into that scene then is actually there.

    Are you serious? It's a larger moral question there, what sort of control do we give away when we decide as a government and a people to kill someone in that situation? What if the Joker then says "I still have the bombs in place, now kill ten people?"

    Also, there were obviously several people who *did* want to kill the lawyer, random citizens shooting at him through the window or trying to plow into the car he is being held in, etc. So you thought it was a plot hole that the police didn't take the official stance of "Yeah, we should definitely just kill the guy?"

    Scary.

  6. Re:Boats on Batman Discussion · · Score: 2, Interesting

    I don't agree. Yes, the joker often lies, but typically to further mess with people. His ultimate goal there seemed to be showing Batman that people have evil in them, and he would much rather have the people that made the choice to kill live and struggle with their own guilt while serving as examples of his point.

    His lie and switch of the locations on the other hand makes total sense, because he wants to bring batman down, test his resolve and his absolute moral code. By switching the locations, he knew that Batman would determine who he most wanted to save, and then would be denied that person.

  7. Re:Farewell sweet Karma on Batman Discussion · · Score: 1

    Well, ultimately a film is a story.

    I disagree with this, most often a film is a story, but I would say instead that ultimately a film is an experience. I look at movies like No Country For Old Men, Lost In Translation, and Once as examples of movies where it's not really the story that makes the movie enjoyable, but the portrayal of something, the presentation of an aspect of life.

    Take the scene in No Country For Old Men when the antagonist is in the gas station and flips a coin to decide whether to let the station attendant live. That's the story in that scene, but that statement doesn't come close to doing justice to the intensity of that scene, the skill with which that scene was portrayed, etc.

    Personally, I found myself riveted by the Joker and everyone's attempt to deal with/understand him. That alone made the film for me. You obviously didn't have the same reaction, but to each there own.

    I think people ask for examples of tackiness, rushing, and clumsiness because they never felt it, and genuinely want to know what set off those flags for you. I thought that batman's snarling was a bit over the top and distracting, for example, but for me and as others have pointed out, this was more of a joker movie then a batman movie, and I enjoyed it thoroughly.

    You are proving his point!

    By the time an attacker has the hashes, the game is essentially over! Do you think a 10 character password is really going to be that much weaker then a 14 character password in the situation where an attacker does *not* have hashes? (And simple controls such as account lockout features are enabled?)

    I think Tippet would prefer passwords to be only complicated enough that they aren't susceptible to brute forcing when account lockout features are in place. His point is that anything past that is not netting you any practical security gain, and I think he's dead on.

    I've heard the speech that this article is referring to and I have to tell you, it's pretty interesting. He talks a lot about trying to take a more practical approach to security, especially security research. Asking questions like "in a given environment, which controls result in an appreciable difference in security?" "Does updating virus signatures quarterly vs. monthly vs. weekly vs. daily make a difference?" Putting aside how you answer such questions (it's not an impossible task) I have to admit that the answers themselves are relevant!

    One of Tippet's messages he stresses in this talk is that the security industry does things differently then other industries and it doesn't make sense. He draws a lot of comparisons to the medical industry because he is a medical doctor as well. In medicine, when we want to know how effective something is, we study it, we design trials, we examine the effects in the field. In security, we tend to go straight from the theoretical realm, debating ideals and their implications, straight to hard and fast rules, without the testing in between. We do ourselves a disservice by doing so. Straight from thinking "Antivirus updates are important and need to take place daily" to a general believe that "if you don't update daily, you are stupid, and insecure" without the in between step of asking "Does updating virus signatures quarterly vs. monthly vs. weekly vs. daily make a difference?"

    Ok, the best you could possibly do is try and reconstruct when the computer was turned on or logged into. At best, you can say that; since the laptop had been taken, it had not been logged into. Even then, that is no assurance that the data was not copied, since the drive could have been taking out and copied.

    If they are accepting credit cards, then they must be affiliated with a merchant bank. It is not possible to accept a credit card without this affiliation. If they are considered a Level 1 merchant by Visa, then they have to go through an annual independent PCI compliance review.

    A level 1 merchant is defined as the following:
    Any merchant-regardless of acceptance channel-processing over 6,000,000 Visa transactions per year.
    Any merchant that has suffered a hack or an attack that resulted in an account data compromise.
    Any merchant that Visa, at its sole discretion, determines should meet the Level 1 merchant requirements to minimize risk to the Visa system.
    Any merchant identified by any other payment card brand as Level 1.

    The PCI Data Security Standard consists of twelve basic requirements and is actually very similar to what is regulated at most banks as per FFIEC guidelines. Every Level 1 merchant must have the following:
    Annual On-site PCI Data Security Assessment performed by QDSPs that are working for a QDSC (individuals that have been certified to perform the review that are working for companies that have qualified to attest to the compliance to the standards)
    Quarterly Network Scan by a qualified scanning vendor. The qualified scanning vendors are screened by Mastercard and are only able to qualify by scanning a controlled environment and producing results that meet the standard that has been established.

  12. Re:Why is microsoft dependent on Eeye and the like on MS Security VP Mike Nash Replies · · Score: 2, Insightful

    This hardly seems fair, if Microsoft's established SDL identifies and fixes a vulnerability in the development process, then it's not going to have a patch released for it to begin with. Before eEye gets there hands on this product, it's already been run through the MS ringer. Who knows how many thousands of things MS has fixed before that point.

    In a product as complicated as Windows, geared towards an audience as general, varied, and uneducated, there are going to be problems! This is an unavoidable fact of life, so what we can do is introduce controls to mitigate those problems. What we can do is design products that address issues in general, so that even if something does slip through the cracks, other items are in place to pick up the slack and minimize the input.

    I have do disagree with the general statement that this was just a bunch of HR tripe, it couldn't be further from the truth. Ok, I can acknowledge that he touts the SDL as a panacea to all MS security woes, but he also makes some excellent points and mentions some changes that really will make a difference. Specifically, talking about minimizing the number of services, what those services do, and what context those service run under is HUGE. Further, creating an environment that is friendly towards people operating their system in a non privileged mode is also huge.

    Further, ... what do you expect? We're dealing with thousands and thousands of developers and product lines here. Educating those developers, holding people accountable to a standard, and putting controls in place is all that really can be done. I guess that's all, on with the accusations of being a mindless MS zealot ;)

  14. Re:There is no point unless... on What's the Point of IT Certifications? · · Score: 1

    Like most things in this world, general statements aren't going to cut it. The statement that "there is no point in getting certifications ..." is correct in some situations, and decidedly incorrect in others. Some certifications are a bit more meaningful then others, surely this doesn't come as a surprise to anyone. The idea that an A+ certification and a CCIE certifcation are equally worthless is crazy. Do you have any idea what it takes to get a CCIE? I guess what I'm saying is that this is not a simple question, some certifications are worth while, some are not.

    Another point that people may not realize is that there are a lot of jobs that require certifications. For example, good luck signing off on any sort of opinion if you are not a CPA. Is the CPA useless? I don't think so. Another example, Visa is now requiring card processors do undergo an accreditation process. This process includes having a certified vendor perform a Visa audit. Guess what, you can *not* perform that Visa audit until you have received Visa training. You know what else? You can *not* receive Visa training unless you have one of a handful of certifications, including the CISSP and CISA certifications. Not convinced? Let's move on.

    There is yet another reason that certifications serve some purpose. They are a statement on at least some level of the competence of an individual. Yes, I know that there are some losers with certifications that are not competent, but think of this from a different light. You are a manager tasked with hiring a person (or company) to perform services for you. Think of how you are going to look if this person or company fails, and hurts your company as a result. At that point, being the one that made the decision, are you going to want to have chosen someone who (however shallow it may be) had some form of legitimacy? I can guarantee that your "certifications are worthless" argument is going to sound a bit feeble when explaining the failure of the project to your boss. If you are a candidate for a job, and on paper and through interviews you are relatively equal, but he has the appropriate certifications and you do not, guess who is going to get the job. This is a particularly true if you are hiring for a position that you yourself are not particularly proficient at.

    Finally, as a person in a hiring position, I do not consider them at all, and am definitely prejudiced against someone who puts them on their resume. Are you kidding me? "Yes, Sir, I know that our latest Network Administrator, the one that I hired, has cost us thousands due to incompetence, but see, they were the only one *without* their MCSE, so it's not like I had much of a choice." Good luck with that.

    So in conclusion, ... yes, certifications are worth while. Some are certainly worth more while then others, and some are arguable worthless, but certifications, in general, are worth while.
