New IE Malware Captures Passwords Ahead Of SSL 986

Ken Treis writes "SANS Internet Storm Center is reporting on a new strain of IE Malware. This one targets bank customers, which in itself is nothing new. But the catch is in the way it does it: it installs a Browser Help Object (BHO) that can capture login information before it is encrypted, and 'watches for HTTPS (secure) access to URLs of several dozen banking and financial sites in multiple countries.'."

    I imagine spybot's BHO inoculation should block this. Anyone know? I use firefox on windows myself, but not for any other reason than that it's just a better browser. ff on linux is actually kind of painful to look at and sluggish to use still.

    To uncheck the "enable third party browser extensions" box in your Internet Explorer properties, if you must use Internet Explorer. This fixes most of the Internet Explorer problems that people ever experience and blame on Microsoft.

    There is the slight problem that malware can silently reenable it when they run, but I doubt many do.

    I tried to switch to Firefox 0.9, but was overwhelmed by the amount of annoying bugs in it. It was constantly crashing on my machine and some web pages simply did not render correctly( probably the web designer's fault). I upgraded to 0.9.1 but some bugs are still there and not all extensions are working correctly. It may be much more secure than IE, but it's not as stable and still has a few flaws. I will wait for the 1.0 release and hopefully by then all those Firefox bugs will be fixed.

    The problem is that websites are test for IE only and are often broke with other browsers. Not because they are using some nifty (non-standard) feature of IE but just because the web developers only test IE.

    I think this will change when non-IE browsers start ruling a larger percentage in the server logs and too many customer complain. I always take the time to send a nice e-mail to websites that are broke with Mozilla.

    Companies need know that they are limiting their customer base and are losing sales.

    Just yesterday I was signing up for a dedicated server at a vendor and their webpage was not working correctly, I brought up IE and worked fine. Ticked - I left and signed up with the competition (servermatrix).

    No, I just meant the whois query was for the correct domain but when I was typing the response here I accidentally added an "l". That info is the whois query for refestltd.com.

  • That sounds nice and all, but if your bank's site only works in IE -- as is true for many banks both large & small -- then the customer doesn't really have a choice in the matter.

    I know people that are perfectly happy to use Mozilla 90% of the time, but when they have to log in to Fleet [fleet.com] (or whatever other bank site), they must use IE there.

    Yes, the problem here is the bank's broken site, but what can you do? Their standard response is "95% of people use IE, so that's what we support", completely ignoring the line of thought that if they wrote in a portable, standards compliant way, they wouldn't have to think about these issues, and their customers would be much happier. But there we are -- stuck.

    Your exclamation points are appreciated, but until the banks & other IE-only sites realize the errors of their ways, you're just berating the victims of the larger crime here.

    To get around the "teaching others to use a new browser", I just loaded Firefox, added a luna skin to make it look like IE, and then used firesomething to change the name to "internet explorer". They barely know the difference!

    But for those that are unfortunately enough to have to help those that insist on IE, for whatever reason, a program called BHODemon might help you. It lets windows users see what BHO's are loaded at any particular time, so I would assume that this malware would show up here as well. Its a quick way that someone can find out just what is running in the background.

    No need. Your can run Firefox from removable media [texturizer.net]. Just get yourself a USB memory stick or USB micro drive, and follow the installation instructions.

    Do this for a few power users, and within a very short time, the IE-only requirement goes away pretty fast.

    Wow, the Finnish bank solution is way overkill. I'd rather have to deal with identity theft every 5 years than to keep a list of one time use passwords.

    The list is a credit-card shaped piece of plastic that has a bunch of numbers on both sides. Goes easily in wallet. Doesn't matter if it gets stolen because you still need the username/password pair and you can get a new list by calling your bank.

    And like I said, you can still use the smartcard version (so you'll skip the typing of one-time-password entirely).

    There is no feature in Firefox that would prevent the writing of the application.

    There is, however, a feature that would prevent the installation of the application. From my experiences so far with Mozilla's various incarnations, you can't silently install plugins.

    I can puzzle out a way for this to run under Mozila, but it's a lot more complicated than under IE. IE uses the global (HKEY_LOCAL_MACHINE) and user (HKEY_CURRENT_USER) registry keys to keep track of plugins. As far as I've been able to find, Mozilla uses a separate registry per profile to keep plugins and customizations working; probably due to an offshoot of cross-platform compatibility.

    The tools for installing the IE exploits are already in place: just convince IE to run some code via a buffer overflow or somesuch, have the code run "regsvr32 myfunexploit" and the exploit is installed into HKLM as a browser helper object. With Mozilla, you'd have to do a bit more work: find a buffer overflow exploit to execute remote code, have your code figure out where the profile directory for the user is located, run through that directory looking for a Mozilla installation, parse out the Mozilla registry, install your exploit code and (probably) wait for the user to restart Mozilla before it's loaded.

    As the article noted, you need a third party application to easily list and modify BHO plugins. Under Firefox, at least, it's a single click to see what plugins you have running.

    This could, in theory, be done with Mozilla-and-friends, but most of the features in the browser, simple plugin viewing and a separate registry, make it, if not unlikely to happen, at least more easily noticed by the end user.

    You will, however, notice that many of the bugs mentioned there are fairly trivial, and (as of Firefox 0.8) several of them appear to be fixed now.

    It's not anything like IE's bugginess and incomplete support. You don't see freak bugs like IE's margin-doubling [positioniseverything.net]. IE also lacks support for :hover, position: fixed, and has many other bugs [positioniseverything.net] and omissions [macedition.com].

    And the fact is, no browser supports all of CSS2. Mozilla (Gecko) has much better support than most browsers, and they are constantly improving it's rendering. Compare that with the stagnation of IE's development over the last several years.

    You're at a serious advantage to the poor saps with IE, but you even with fully up-to-date everything, worms can attack windows before updates are available. The same can, but doesn't, happen to Linux.
    So yes, if you have uptodate virus definitions, a firewall, patched machine and use a real browser, you're unlikely to be infected. Still, there're other problems, and often the most voiced are the *nixers, which was what the poster was referring to.

    Did you RTFA?

    This is a .gif file. Even those who are smart enough to disable Microsoft's filetype hiding (because, obviously, users are too stupid to deal with file extensions) would think that this is a quite safe, viewable file. But Microsoft, in their infinite wisdom, ignores the extension and determines what type of file it is by examining the file structure directly (exe) and goes ahead and executes it. Designed this way e-mail filters that deliberately exclude executables (to prevent this very kind of attack) are fooled into passing this right along.

    Don't you see a number of design problems with this approach? Don't you have to wonder whether Microsoft actually wants trojans and spyware when you see this? And if they do want trojans and spyware, what kinds of holes do you think they will design into .NET Longhorn?

    So rename Iexplorer.exe to Iexplorer.exe.bak and make a shortcut to firefox.exe. Any app that tries IE will really get Firefox. You can also "uninstall" IE under MS Windows. You don't really get to uninstall the core IE stuff, but you can remove Iexplorer.exe which is just a crappy front-end to a crappy engine. At least this way no app could use Iexplorer.exe directly.

    Well, you must never have really RTFM with Opera then(probably Firefox either).

    1. On Win (which I must still use sometimes), ffox is the slowest of the 3 (especially re-draw), even though I'm always on the latest release.

    Well, not having used Firefox, I don't know. But I find it hard to believe anything could be slower than IE in my experiance. 40+ seconds(on dial up true) to load a page that takes 11 seconds in Opera. Pathetic.

    2. I can't get the other browsers to do the simplest, stupidest things I can do in IE, e.g.: drag/drop shortcuts between address-bar & folders, or File=>Send=>Shortcut To Desktop, or drag a link from a page to the address-bar (a sure-fire "use the same window, dammit"). I dunno, maybe I just didn't RTFM.

    I can't grok why anyone in their right mind would want to do this, but I believe you can just go add to bookmarks that is at the top of the list inside a submenu in the bookmark list. Can't send a shortcut to the desktop... you can copy the address... again, I can't see any real reason to do this. It's pretty easy in Opera to open a link wherever you want, either as a button/click or rightclick option, but you can also drag a link from a page to the address bar.

    3. I make genuinely productive use of toolbars (e.g. Google) unavailable on other browsers.

    Again, in opera it comes default with a search option box for google, amazon, alltheweb, etc... You can add your own. Opera comes with pop-up blocking. I can't comment on other bars as I don't use them, nor have any idea which others you use but did not mention.

    I don't grok the excitement of tabbed windows. I much prefer being able to position pages independently in separate windows. And if one of those windows crashes or hangs, I don't lose the others (or their back-traces).

    You are very lucky, every time IE crashed for me, it took all it's windows with it, and the task bar(system tray stuff) - even in XP pro.

    Opera has MDI, which is more than tabbed windows, you can arrange as desired inside Opera - much less task bar clutter. Ever tried the Continue from last time? Right back where you were - even after a crash, and keeps history (what you mean by back traces I think).

    As for security, I do quite well with the combo of common sense, frequennt AV updates, SpyBot, AdAware, WebWasher, and very aggressive/paranoid firewall settings. (I love Agnitum Outpost, which lets me control cookies, ActiveX, JavaScript, etc. -- each *separately* -- on a per-domain basis.)

    Well, I use AV, spybot etc, but since I stopped using Kazaa, and have been using Opera, guess what? I haven't found any spyware with SpyBor or AdAware (I don't use webwasher as it costs $$, and as I'm not getting infected I don't see the point of wasting money). Good firewall settings are a good idea, and I commend you. However I don't have to use my firewall to keep my browser in line just by using Opera. Much easier. Although, I do also recommend Proxomitron. Great ad control.

    In Germany and Austria, online banking requires a TAN (Transaction Authorization Number) for any operation that changes the account.

    the TANs come one a one-time-pad kind of sheet and you can use each number once before they become invalid. Therefore, if somebody is scanning my TANs (along with other things), they can do exactly nothing with it.

    The sheet of TANs is generated on some bank server and sent to me via postal mail.

    Admittedly, i wouldn't want anyone browsing my bank account. But the damage they can do with that is limited (changing passwords and so on requires a TAN too).
