New Attack Fells Internet Explorer 202

Posted by Soulskill from the tricking-an-old-dog dept.
alphadogg writes "Attack code has been identified that could be used to break into a PC running older versions of Microsoft's Internet Explorer browser. The code was posted Friday to the Bugtraq mailing list by an unidentified hacker. According to security vendor Symantec, the code does not always work properly, but it could be used to install unauthorized software on a victim's computer."

      old != unpatched.

      The article says IE 6 and IE7. It does not say unpatched. For many people these are their current browsers as they have not upgraded to IE 8. For business users, their companies may still insist they use older browsers until they are able to migrate certain software to the new version.

        Or upgrade hardware - we have a variety of customers who's machines are too old to run IE7 or IE8 efficiently, and who have no plans (or budget or whatever) to upgrade their hardware until it dies or is very near death.

      It mentioned versions 6 & 7. Considering how long people hold onto their verison of IE, it will be ages until IE7 disappears. Also, MS does have some contracts with companies that means they're stuck on Win 2k for now which means nothing greater than IE6. Granted these companies could use FF but understandably they're paying for support from MS and want to use a browser they will support.

        I really don't think you are right about that. There will always be those home users on dialup that don't run automatic updates ever but they are not very useful in a bot net anyway. Most people will get update to IE8 weather they mean to do it or not. IE 6 lives in the corporate space because it was around long enough for its own software ecosystem to develop in and on it. IE7 was around for like a year before 8 was released as beta and 8 does not break much compatibility with 7 its much less significant than 6 -> 7.

        I doubt there is much code out there target at 7 that does not work on 8. The projects that do would have to have been pretty small and would have been designed and completed in a pretty narrow time window between 7's release and the pretty clear public information on what was coming in 8.

For example, IE 6 was shipped with Windows XP and so will be supported until Windows XP ceases to be. What this means is IE 6 is guaranteed to at the very least receive security fixes and limited bugfixes until sometime in 2014 when Windows XP leaves support. Similarly, IE 7 was shipped with Vista and will be supported until Vista ceases to be; contrary to what others may

    Microsoft Windows has once again trounced all comers in security, with a recent survey showing 59% of all Windows machines on the Internet being infected with malware and under the control of botnets. Malware rose 15% just from August to September this year.

    Windows users continued to be stupidly complacent Typhoid Marys, telling Mac and Linux users that they were every bit as susceptible to viruses and Trojans, despite the Windows:Mac:Linux virus proportions in the wild continuing at approximately 100%:0%:0% for the fifteenth year in a row, and pumping out gigabytes of spam and denial-of-service attacks from their thoroughly 0wn3d computing cesspits.

    is a definitive software engineering treatise on the history of IE security exploits.

    It is certainly true that there is a kind of economic network effect going here. For many years we saw so many web sites that only worked properly with IE because IE was so dominant. The same factor naturally attracts black hats looking for systems to exploit. Once we factor that out, what can we learn from how IE was conceived and maintained?

    Did clumsy code-reuse and maintenance play a significant role? That is did they stretch existing code to do things it hadn't been designed to do because it was close enough to pass the demo test on time? That's a decision we all face; we'd all *like* to rewrite things better when we take a look at them, but in the real world we've got to ship good enough code on a deadline to justify our salary. I think MS might be particularly vulnerable to the "killer demo" imperative. They are a business that is dependent on organizations choosing entire MS product stacks because they *anticipate* something they're going to need in the future will be dependent on something else in that stack.

    Did "business strategy" considerations confuse priorities for system requirements? E.g., The decision to make IE a fundamental part of the OS allowed MS to gain control of (destroy) the browser market while evading anti-trust regulation. Did that result in undesirable coupling of IE to the underlying system? Did the desire to leverage browser market dominance to give other MS products a competitive advantage create confusion in requirements or priorities?

    Were there cultural attitudes that made security and quality secondary? E.g. Did MS value having shiny new features soon before doing a quality implementation? Did their success at achieving effective control of the browser market cause them to under-invest in maintenance because they had no competition worth worrying about?

    These are the kinds of things I'd like to know. It's almost past the point where any individual security flaw in IE is interesting to me, because there have been so many and will be so many more. It's time for a really first rate summing up by somebody who knows what he's talking about.
