    be aware the runnable patch is completely unofficial, the only action microsoft suggest is unregistering a vulnerable dll which only mitigates the most common method of exploitation while not fixing the underlying problem.
    NFI how long it will take microsoft to have an official patch out, but from the sans site, it doesnt look promising that it will appear soon.

          If such a site were to exist, people would start catching on that it's all Microsoft's fault in the first place. Then people *would* switch to other systems.

          Nope.

          I've had conversations with regular non-techy people. They don't get it; they think that they are safe and/or don't want to think about the dangers or alternatives. Ever. It is not possible to convince them and if you point them to a technical site, they will ignore it. They must come to the decision by themselves after long years of abuse, if they drop Windows at all. That said, to my surprise, my brother in law decided to get a Mac Mini for his kids this Christmas. I gladly helped them configure it and bring over data from the old Windows box they (unfortunately) still use. I've given him that advice for about 5 years, and did not talk with him about it for the last 6 months...so whatever I've said or pointed out to him had very little to do with his decision. (My brother-N-L is a smart guy and does not ignore most other advice w/o good reasons.)

          Personally, I just refuse to help them to secure the Windows-based systems they chose to use unless it is a single-function server that I can configure how I see fit. I do reinforce with them just how hard it is to use Microsoft's products in a safe manner; 'exceedingly frustrating and still I'm unconvinced that it is secure when I'm done' is a phrase I use often.

          NOTE: I _DO_NOT_ subscribe to the idea that if you keep a system updated with the current patches, use a firewall, and be careful, it is safe to use. If that system is safe, it is more by luck and chance and not by your hard work. This exploit is a perfect example of how all those methods fall apart and can not be relied on.

            There is a lot of in house software out there - which is why MS Windows98 was installed on a few single purpose machines where I work this year. The current developers are making all new software as portable as they can - and not developing to the moving MS Windows target.

            The earlier poster was correct - some poeple have no choice but to use MS Windows - but the answer as it has been for years is not to let their machines onto the net without adult supervision. I completely block this MS windows clone of IRC and it doesn't bother anyone - using instant messaging for business communication is a braindead idea anyway unless everyone is tied to their desks and focuses on short term tasks, and luckily I don't work in such an environment.

      We've all been trying this years ago. But just yesterday, I got my ass kicked down to troll and flamebait for daring to suggest that Linux/Open Source/OS X/BSD/Anything-but-Windows is anything but an utter turd. What hope is there to educate a public who cannot get past the idea that the internet is just AOL and Bill Gates invented the computer and a hundred other misconceptions? You're advocating college education for people who can't pass kindergarten.

      From my ledge, I see it as counterproductive to call users "Joe Sixpack" and "Gramma". These are false stereotypes. Given the opportunity, anybody can learn. Nobody was born knowing Windows 20 years ago, but it caught on, didn't it? There's more "for Dummies" books where "DOS for Dummies" came from.

      But yeah, I do my part to post hints 'n' tips every other day on my geek blog, but it's more directed at people who've already found Linux. I tried in a past life to do similar for Windows users, and got nowhere: it's a hole with no bottom.

    To fix the security risk of IM, either the you give up point to point email that it is to force it though filtering servers (sound like email there again). The Anti-Virus programs on every machine will have to start filtering all that traffic too (wait they are doing this for wmail today also!!)

    I do infosec stuff at a well-known corporation, including Incident Response, and I've been following this closely & working on our response.

    Since the first exploit came to light, H.D.Moore of the Metasploit project has reworked the original package they did. The new exploit spits out exploit WMF files [sans.org] that come:

    • with a random size;
    • no .wmf extension, (.jpg), but could be any other image extension actually;
    • a random piece of junk in front of the bad call; carefully crafted to be larger than the MTU on an ethernet network;
    • a number of possible calls to run the exploit are listed in the source;
    • a random trailer
    This makes it rather hard for antivirus and IDS sigs to detect it, though Snort and the A/V people are working late over their holidays to improve detection.

    SANS/ISC have provided excellent continued summaries of events around this. Here's their FAQ on the issue [sans.org].

    This is looking truly horrible. On Tuesday morning zillions of Windows desktops will be fired up for the first time in a week or two. This thing's already in widespread use by a number of malware distribution networks for the usual reasons. As such it's a nightmare for network and system admins with Windows machines to look after (and us security people trying to provide advice & assistance for them...) But the stealth nightmare is that this is an absolute jackpot for the less visible targetted attacks, such as those emanating from China for the past couple of years (google around, Slashdot and Schneier have covered this as well as many other places.) There are also the opportunistic types who see an easy opportunity to pwn some key machines where they work, say. I will stick my neck out here and make a prediction. Virtually all organisations with Windows machines are effectively wide open to total compromise by a reasonably informed person. That means much of the IT dept as well as significant numbers of the 'interested poweruser' types, developers with a casual interest in security,.. anyone who's heard of this and is capable of running the findingm, running and using the new exploit, basically. Of course we're all tweaking our IDSes and antivirus, locking things down as tight as possible in the 48 hours remaining, but... *shudder*

    For ten years I've been waiting for Microsoft's luck to run out. This is about #3 on my list of catastrophic MS incidents. There aren't many ways things could be worse.

    It will be a good time to be running Linux on work machine, though :)

      I work for a major electronics retailer in the Service department. Most of our duties are simple PC repair, data backup, and virus/spyware removal.

      I have seen in the past week our work increase 5 fold because of this exploit. What is normally a very slow time of the year for us has become very busy for us and it's making me nervous myself.

      We had a few customer that bought brand new computers and laptop and are bringing them back the same day with this exploit. A quick check reveals that their Norton was up-to-date, yet this stuff still slipped in. Other customers are getting this thing left and right. Unfortunately I have not much to tell them except to keep updating all your security products daily as it's only going to get worse before it gets better. Hand them a copy of Norton and Sunbelt Counterspy and tell them good luck.

      I do believe there is a bit a social engineering planned into this. Customers with year-end financials, tax season starting up, holiday credit card payments and statements coming through. Very ripe time to plucking financial and personal data. And with this being an extended holiday weekend, this exploit has a bit of time to fester and refine itself before the big trojan/virus with a major payload slips past the AV and Adware detections and onto millions of computers. What happens when someone combines with exploit with a backgood into a major ad server network? Imagine the damage then.

      I'm doing the best I can at my house against this thing, but looking at the 7+ Windows boxes I'm now worrying about updating, installing, patching and unregistering, and the 1 Apple laptop I haven't had to restart in 6 months, and I wonder if this is going to be the big one that really gives Microsoft the black eye it can't recover from.

        If you're an IT pro and you're running Windows at home, you should have your boxes imaged so you can just unhook from the net, image, apply the fix, take a new image and hook back up to the net. Seven boxen shouldn't take you more than a couple hours -- less if you use a standard image.

        If you're setting this up for the first time, don't forget to redirect "My Documents" to a different partition, or better yet a server with a backup regime. Oh, yeah, and choose the "Activate Windows over the phone" option before you make your first image so you don't have to re-activate each time.

        If you're an IT pro and you're not using Windows at home, take the extra hours and spend some holiday time with your friends and family. Life is short.

        I know next to nothing about IM/RSS software, so I am just speculating here.

        But suppose you had some IM/RSS client [MSN, AOL, Yahoo, whatever] that had an image rendering aspect to it. For example, suppose your IM/RSS client were capable of rendering the JPGs in an HTML message.

        Then it seems to me that if you had such an IM/RSS client running on your desktop, and if someone knew your IM/RSS handle, then they could send you an IM/RSS message with very elementary instructions for downloading the evil file:

        <img src="http://blackhats.com/evilfile.jpg">
        and you'd be hosed without ever having clicked on any link. And if the worm were really smart, it could then install "thttpd" trivial http daemons to spread itself internally on any corporate network [via each person's IM/RSS "address book"].

        If that's true, and if lots of employees left their computers running and logged into windows with such "automatic" IM/RSS clients running on the desktop, then Tuesday or Wednesday morning [or whenever people decide to come back from their New Year's vacation], there could be literally MILLIONS of infected machines.

        So the question: Are there IM/RSS clients that can download files automatically?

            Apparently the attackers aren't awesome programmers because history has shown that the real danger comes after a sample exploit is made, not when the info becomes known.

            Apparently you fail to realize this was a 0-day exploit. That is, there were people already exploiting this flaw before anyone else found out about it. Because they didn't release their source code do you feel safer by this? So your argument that the attackers aren't "awesome programmers" is completely worthless because these attackers found and wrote the original exploit code to begin with. We don't know how long this flaw may have been used in the wild before this one was found. Some "awesome programmers" could've been using this flaw years ago to break into networks. Re-read my original reply.

            Now some people who happen to have analyzed that exploit figured out just exactly how seriously this flaw is and what could be done with it if it's not fixed.

            A simple explanation is plenty.

            So you're saying that if all the attackers have is a simple explanation that they wouldn't be able to write code based upon that explanation? Yeah right. The people who wrote these sample exploits didn't even have that to begin with and look at what they've been able to come up with. The people ("attackers") who wrote the originally known exploit didn't need a simple explanation either.

            So now virus scan writers and IDS maintainers, etc, now have a LOT more information for how to defend against this particular threat. A simple explanation isn't sufficient. Now scanners and IDS can use these discovered methods to improve detection and prevention of exploitation of this flaw.

            Again, I just don't see why someone would need to make the most evil version of this possible and distribute the source code.

            Well, I can't explain it any clearer. You're using the "security through obscurity" argument that history has shown to be insufficient for protecting our computers and networks.

      ...Because it's a simple image. Who would think that an image can deliver such a nasty payload? It doesn't need any user interaction. This blows right through fully patched copies of windows, and IE opens and executes it automatically (video here - http://www.websensesecuritylabs.com/images/alerts/ wmf-movie.wmv [websensesecuritylabs.com])

      Does your website have an image on it? It can be exploited that way. Does your email render html, even with scripting turned off? It can be exploited that way. A few trusted sites have been compromised with this exploit. Some seedier as networks (with hundreds or thousands of affiliates) are using this to generate cash. There is no patch for Windows ME, 98, or 95 and there will never be as these OSes are unsupported. These systems will ALWAYS have this vulnerability.

      Imaginine if someone uploaded this to MySpace (http://www.alexa.com/data/details/traffic_details ?q=&url=www.myspace.com/ [alexa.com]), as they allow full html formatting, embed, iframes and all kinds of crazy crap. One exploit on a popular blog will cause A LOT of damage.

    From http://isc.sans.org/diary.php?rss&storyid=994 [sans.org] :

    1. Microsoft has not yet released a patch. An unofficial patch was made available by Ilfak Guilfanov. http://handlers.sans.org/tliston/wmffix_hexblog13. exe [sans.org] Our own Tom Liston reviewed the patch and we tested it. The reviewed and tested version is available here (now at v1.3, MD5: 14d8c937d97572deb9cb07297a87e62a). THANKS to Ilfak Guilfanov for providing the patch!!
    2. You can unregister the related DLL.
    3. Virus checkers provide some protection.


    To unregister the DLL:


    * Click Start, click Run, type "regsvr32 -u %windir%\system32\shimgvw.dll" (without the quotation marks), and then click OK.
    * A dialog box appears to confirm that the un-registration process has succeeded. Click OK to close the dialog box.
  • It's odd but I've noticed a lack of Microsoft cheerleading over the past couple of days. I'm sure as soon as a patch is made for this latest Windows exploit the cheerleading with resume with the usual vociferous putridity. Shine on!

    If i rename a malicious .WMF as a .JPG, and display it as an <IMG> on a website, will IE execute the WMF, or will the JPG just not work?

    JPG, PNG, GIF etc. all have headers that should surely be checked before displaying the picture. Do IE not do this?

    In short, do i have to actively click a "Open this file" dialog on the browser?

    If this works as advertised (executes arbitrary code, and arbitrary like fill gnome's teapot with iguanas as that's arbitrary) then I suggest a whitehat should use it to execute the download and installation of Firefox, whilst nuking that offending .dll and IE, or perhaps installing the patch.

    technically: "this is a DLL which gets injected to all processes loading user32.dll. It patches the Escape() function in gdi32.dll. The result of the patch is that the SETABORT escape sequence is not accepted anymore"

    vulgarly: "don't trust the firewall filters, don't trust the antivirus vendors, don't wait for Microsoft. Install the patch immediately. If you are running a Windows operating system the patch doesn't support, time to shut it off and wait."

    Netherlands being the place where it first appeared, and being from Belgium myself, I can say that everybody here simply says 'MSN' when they mean 'MSN Messenger'.
    It's more common in europe anyway to use MSN instead of other popular IM networks used thoughout the USA and other countries. IM was never popular with non-geek computer users here and when broadband internet (with a fixed price/month) arrived most teenagers (the primary group of users in europe) all started using MSN Messenger.

    Talk about trolling flamebait. Apple makes money on hardware, not operating systems, so it behooves them to make their operating system work on their hardware. The nice thing about this is that they make some damn nice harware (I'm typing this on a PowerBook), and that they have very little incentive to 'feature-pack' their OS like Microsoft does -- so you get less in the way of quirky 'features', and a hell of a lot of functionality.

    Plus, OS X is a Unix, which means it plays nicely with other Unices, and it behaves like a Unix on the command line -- so I get all the power of pipes, vi, Bash, the BSD ports collection (a la Darwinports), gcc, and so on. On the GUI side, it behaves like a Mac -- and I think you'd be hard-pressed to fault Apple for their GUI design.

    Best of both worlds; you just have to shell out a slight premium for the hardware, and given that you get a REAL OS with it, I'd say that Mac offers a better bargain for the desktop user than any Dell or Gateway.

    First of all your comment is largely off-topic, causing mine to be as well, but I am only responding to this because I could not bear to read what you wrote and not answer (Mods, please be compassionate!)

    You are addressing to largely unrelated issues as one, Freedom of software, and usefulness of the company. Allow me to address them seperately.

    The former (Freedom) is a much bigger problem with Windows than Macs, at least with Mac OSX. Sure, they both use proprietary code, but at least Mac OSX uses some Free software.

    The latter (usefulness) is very subjective. No doubt Microsoft would think they are useful, while Apple thinks they are. As much as I do not like Microsoft, I am going to have to say that it *and* Apple were both useful, if not so much now. They did start a revolution of computing at home. Unfortunately, it has taken a bad path over the years, but it is the same sort of idea.

    As a final note I would like to ask, why did you think you would get +5 funny? I find nothing funny about what you wrote.

    Point being that Microsoft has always promised very high and delivered extremely low. You're more fortunate than most since you know about and use alternatives. In userland, most of them are just recently realizing that they been sold "da bridge."

    completely agreed. it also shows something of a lack of effort on microsoft's part. i believe that the problem has still not been fixed with an official patch (others have to do the dirty work) and i think the vulnerability was known about four days ago! That is unheard of on open source systems because their creators aren't busy marketing the newest XBox game. I recommend gaim or naim (if you don't mind console) for the aim and everything. I hear Trillian is good but have not gotten around to trying it yet. I believe it is for windows, no? Probably has better protection against this stuff than MSN does though (that doesn't say too much...) (-hrair-)

  • I got my first taste of personal computers in 1999, I got a laptop with Windows 98se and had nothing but problems. I determined that it was broken-i.e. a poorly designed tool. The majority of the people I questioned about this said, "it's just the way it is, accept it." I am not one to keep a broken tool-as I build houses among other things (http://my.opera.com/emotional1/albulms/ [opera.com]), so I searched around and someone suggested Linux. As I had no computer experience it seemed to me that it did not matter which way I went-Linux or Microsoft-I would have to learn. That has been over five years ago and I have many computers and just recently switched my mother to Linux-because it just works. BTW My mother is very practical-she just wants it to work-I can't blame her. Microsoft is very busy trying to hold on to it's market share which has always appeared to be more important than spending much needed resources on its basic tool-Windows OS-any version. I am grateful every day that I made the right choice- and when a friend asks me if I will fix their computer I tell them I will fix it by replacing Windows. I feel for you, it sucks when you buy something that 'sort of' works, only to find out that they are already focussing on the next version-which will follow the same tired pattern, instead of fixing what they shipped 'unfinished' in the first place. It is nice that some guy wrote a patch to fix this, that's the kind of spirit that I have found using Linux over these past years--BTW I do contribute money to the projects that I use frequently and am available to spread the word that there is an alternative to Windows.
