        If you think you can do better than Fortune 100 support teams, you are sorely mistaken. They have all the time, money and employees they want to throw at this problem and still get their ass kicked. People trying to tweak non free software are working in the dark and will always be surprised. No matter how much they spend, they can never fix the problem.


        The reason that the corporate world has issues with bots, has far more to do with the corporate environment than it does with the security of the platforms involved. After all any sufficiently secure platform can be made insecure by allowing the wrong morons to use it.

        On my home network, I can do things like block every single incoming port and disable pretty much all of the outgoing ones as well. I can install firewall software on each computer to scan the remaining ones. I can create my own install media to remove nearly any part of windows which isn't related to the bare essentials, then install the bets antispyware software and demand that anybody that uses the computers not click on links in email.

        I'm sure there's more, but I would be surprised if I were allowed to do even that much if I were responsible for securing a corporate network.

      "internet licenses" have been discussed ad nauseum, and fact always arises that any such implementation would simply be elitist and exclusionary.

      Basically, an internet license is a bunch of computer guys telling the rest of the world that the internet is an infrastructure made for the geeks, by the geeks, and of the geeks. If you really want to join the club you can take a test so we can determine if you're suitable, but otherwise, you're unfit to participate.

      Look, you're not going to kill anyone being a bumbling participant on the internet, they way you might in a car or with a gun. Yes, it is possible that you unwittingly might cause some economic impact to someone, but is that a flaw of the user or the system? I submit a banking system that lets an ignorant user leak his personal information which can then be used to ruin their credit is broken. I further submit that a system that lets a zombie computer join thousands of other computers in a criminal enterprise is broken.

      The problem doesn't just exist between the keyboard and chair, but also in the policies, protocols, and systems that allow a new or ignorant user to fail so spectacularly.

      "stupid people"

      Because someone does not know much about computers, and specifically computer security, does not make them "stupid". It most often means that they have things they they are skilled to deal with. Because you probably cannot perform open heart surgery does not make you stupid either. It means that you probably know about computers and their security. We all have our areas of expertise and interest and they cannot be everything-there is only so much time and mental capacity.

      This type of attitude I find prevalent among people who know a bit about computers. This is one of the reasons that Linux has taken so long to be usable for the masses. Most people do not want to build their own computers and most people don't want to have to learn about computer security. They want the people who specialize in it to make it where it works for them.

      Part of the Storm threat is that it is able to intimidate those who stand up to it, or attempt to combat it. This would suggest that Storm is in turn vulnerable to an attack by an even bigger botnet. It can succeed on poorly protected machines and lurk in the many dark corners of the Internet, like cockroaches. Suppose enough of us willingly subscribed the spare cycles in our machines to serve as a botnet that would fight the others? Could that work?

      Can we come up with a working definition of 'good' for such a botnet? I would not subscribe my machine to any government directed search for terrorists, for example (that's probably got me on a no-fly list). However, it should be possible to confine our botnet to the named botnets in the article, and do 'good' in an sense that would be acceptable to most users. If the project veers towards evil, then there must always be a way to unsubscribe.

      Then, we want a fancy UI like the SETI screensaver, so we can see how we are doing, and root for our side.

        Probably because it's not the heart of all these problems. The heart of all these problems is that a billion security-unaware people operate computers that are connected to the internet.

        No, the heart of the problem is that windows, despite what M$ claims, was not be designed for those people and as a result those people make mistakes.

        Software is soft, it can be anything we want it to be, and assholes who claim that "software can't do software related things" are lying through their teeth.

        If thirty odd years ago windows had been designed responsibly we wouldn't have the mess that we have now. Amongst many other things when connected to the net they deliberately confused static data with executables and deliberately ran all programs as administrator. Things that mainframe OS' and Unix had understood and solved decades before. I can remember the very first time I saw a web page with an executable and thinking "you stupid fucking idiots". The ramifications were obvious right from the start; M$ just chose to ignore them.

        The marketing parasites, and their patsies, who to this day continue to claim that windows was not a large part of the problem are lying arseholes. M$ is slowly improving their security but they still have a long, long way to go with a culture that still tries to test for security rather than building for it. And yes, despite what some idiots claim, security and user friendliness are not mutually contradictory. In fact they are more complimentary than contradictory with well built security systems helping users to make good choices for their own safety as well as everybody else's.

        In Protected Mode, IE7 on Vista is genuinly sandboxed, and throws a fit if you so much as do a right click View Source (which would run an executable: notepad by default). If the browser was actually standard compliant (sometimes by the time Duke Nuken Forever and Spore comes out I guess), it would be an excellent all around browser.

        Other stuff, like running an executable sent to you by MSN is so freagin hard it puzzles even me sometimes (I beleive by default you have to change something in the registery, or it simply will flag em and you'll never be able to so much as extract exes from a zip file). Thats probably pushing it too far, but point is, if you don't have the admin password, its relatively difficult to do something retarded aside to hit your own account (which is possible in any OS really, and even then, you get quite a few warnings).

        Something of interest, though not really related: Once I installed some game (I forget which) that tried to install a copy protection crap, and Vista actually asked me if I wanted to install it separately from the game itself (I got 2 pop ups). Said no, and it happened that this particular game would run without the copy protection...so I was able to tell it to shoo off (while my friend on XP hosed his install because of it...a patch came out the week later to fix the issue, but I never had the problem in the first place). MS is learning. Slowly.

    Within hours, typically that botnet has replicated to all of the machines on the internal network. Worse, now that botnet has access to your critical database information, consisting of customer records. Often times, the brains behind these botnets can better datamine than your business can, finding interconnections with your customers to better flood them with spam, or worse.

    So the world's largest networked super computer runs Windows. It is sad really, all these hundreds of millions of computers on the planet - half of them sending spam for the other half to filter out. One would think that there should be something slightly more useful for them to do.

      Ah, the old innocent looking URL trick. Like I'm going to fall for that!

    You see this is exactly why Windows is winning. Linux is still yet to provide a credible botnet to face off against the Windows botnet. There's just no comparison, Windows wins every time!

    Botnets and I cannot lie... :)
  • This is all converging towards the worm described in the Curious Yellow [blanu.net] whitepaper from back in 2004. I'm frankly surprised it took this long.

    From TFA:

    They have young, talented programmers apparently.
    If you want me to put it harshly ... "young" programmers and "young" technical managers at Microsoft who signed off on ActiveX et al, are totally at blame for the problem. We, the more elderly of the communty who programmed the internet in the first place, discarded executable content over the wire. Unshar was written for a reason!

    The sophistication of this Storm "application" is much more indicative of a mature elder programmer, who probably has read the complete cypherpunks archives. We talked about stuff like this long ago. Compare to things like the Morris worm, the two Manila children, etc. Those were intense, but brief due to coding errors and the like.

    Bah. No, these people are not children and they do know what they're doing.

    It's really nice to be a linux user for over a decade and sit back and say "ha ha". I don't believe Microsoft is capable of combating, or willing to combat, the problem. At the bottom of this issue however, is the fact that many users are clicktards. Infecting a linux or mac system is as easy as tricking a user into clicking something, or even simulating the pop-up password dialog box for a sudo event. Let's start with Fedora for instance. The ssh service, by default, allows root logins. How many users would enter their root password into a javascript popup that is titled "New updates for your Fedora system are available. Enter your root password to download and apply these updates"? I'm not picking on Fedora, it's a great distro. I certainly don't agree with PermitRootLogin yes as a default in sshd_config. Regardless of firewall settings, it's foolish. Alternative systems should be taking a cue from the shortcomings of Windows and doing what they can to minimize their own strike zone.
