Tricking Vista's UAC To Hide Malware 221

Posted by kdawson from the protective-coloration dept.
Vista's User Account Control, love it or hate it, represents a barrier against unwanted software getting run on users' computers. A Symantec researcher has found a simple way to spoof UAC and says that it shouldn't be completely trusted. The trick is to disguise the UAC warning dialog in the color associated with alerts generated by Windows itself.

It's the same armor that protects your Windows password from keyloggers. Whether or not it's secure remains a largely open question. There are no exploits I've heard of to breach it, and Microsoft would (eventually) patch said exploits if they became apparent.

      The main problem I have seen with Vista since the first RCs is the monotonous regularity that these messages pop up with during regular system use. The old adage that practice makes perfect is incorrect; Practice makes permanent is the real outcome and microsoft is basically forcing their customers to practice hitting that continue button while still trying to concentrate on the tasks at hand.

      I have found myself clicking continue at the same time my thought registers to *not* click because of something not looking quite right.

        The "OK/Cancel mistake" has been in usability textbooks as an example of what no to do for more than a decade now. It is quite clear to anyone who has had any formal training in human-computer interaction that either MS hires the worst UI people on the planet, or the marketing department overrides all of the UI people's proposed changes. It is also clear that either MS is only vaguely aware that UI deign is an important part of security, or they are a lot more interested in providing the perception of security than the reality. My opinions is that Vista security is a lot like searches at the airport. For the most part it is completely ineffective at actually increasing overall security when it is important, but it is very, very visible and "in your face" so people assume "something is being done" and are mollified.

    With every release of Windows, Microsoft seems to devise some new, overly-complicated scheme to try to protect Windows users. The scheme they came up with may sound great, but then it falls flat on its face because of some minor flaw or workaround.

    So maybe what they need to do is to get back to the fundamentals. We only need to look as far as OpenBSD to see how keeping things simple and intelligent results in a very secure operating system. Instead of writing new (and probably buggy) code to try and prevent things like malware, they just repeatedly go over the code they already have, to try to ensure that it is exploit-free. And it works. OpenBSD is a damn secure system.

User level permissions are more than sufficient to start up some malware automatically every login, not to mention sufficient to wipe out all of your important data.

    While it may be true that different colored borders are supposed to mean varying levels of "trust", as in what component is running, I don't think any user would know that. The text in the dialogs doesn't appear to be different (that I can tell), so why would a border color make me go "Oh, I should let that action happen, I bet that's some Control Panel action", especially when I wasn't working with the control panel.

    To be honest, Vista's UAC saved my butt recently. I have no idea what application was vulnerable -- but it somehow tried to run exec.exe, which was downloaded into one of my temp folders. The file was deleted after it failed to run (because I said "no"), and then would appear back in a few seconds and try to run again. I'm happy that whatever application was vulnerable wasn't able to do anything to my system.

    <tangent> Anyway, while some people may say it's annoying, I'm not sure exactly how many actions a typical user would take that would require UAC prompts. After the first few days of configuring, installing apps, etc..., I have little need to do anything that requires UAC prompts.

        "Computers seem to be heading in the direction of becoming more like appliances; "

        True, and we are in a dangerous "middle-ground" between a complex tool that only knowledgeable people use, and a true appliance that anybody uses.

        The problem is that the operating system is too brittle and vulnerable to be considered an appliance. Do you ever think about how you use your toaster? If I put this new organic untrusted bread in the toaster will my toaster be taken over and corrupt the blender and waffle maker and start a kitchen rebellion? If I put in this DVD of "Ishtar" in my DVD player will it require a weekend to reinstall it's OS and useful applications?

        No, that doesn't happen because appliances are robust and there isn't much a user can do to hurt them when used in their intended ways.

        Now the current computers (particularly windows) are becoming appliances but haven't gotten to the critical point where they really become appliances. that transition will happen when a big chunk of the OS is hidden from the user and the user works in a Sandbox. It will be a lot less useful because it will only do what it was designed to do, but it will be safe and reliable for it's intended purpose. Then it will be an appliance.

        The problem is that computers are sold as the answer to lots of the average user's non-problems. Like any good for sale in a capitalistic society, it's jammed down the throats of everybody the seller can get their hands on. So lots of people who maybe shouldn't be using computers (in their current unrestrained form) are using them (they are the ones who you get your spam from).

        This is a windows problem not only because of shoddy engineering, but also because of Microsoft's position in the market. Let's look at the three major OS's:

        Linux (BSD et al): It's a computer hobbiest's paradice, lots of great code, well defined heirarchy. Plus in general hard to get your hands on if you are "Joe User" who just wants to get a computer to e-mail the kids at school. This means that the people who are using this os WANT to use it for some reason (insert long list here), and they are going out of their way to use it. This means that this segment is typically very computer savvy and not likely to be pwned as a group.

        Macintosh: This is also a "Harder to get" computer for two reasons. First, they are very expensive compared to the best-buy special. Second they are only sold in a few places. These two reasons make the Mac a sought-out computer rather than what the sales droid told you to buy. The average user is probably less computer savvy than the average Linux user, but in the case of the Mac, apple also "has your back" to some degree with frequent patches and a well designed core OS that minimizes your risk to begin with.

        Windows: This is the default OS you get if you close your eyes and pick a computer. This means that if you have no clue about computers, chances are you get a windows box. Its fertile ground for stupid users to take advantage of (can I interest you in a free screensaver?). And in addition to that, MS has huge legacy issues that they can't change or they break business apps. MS has painted itself into this corner by selling to the lowest common denominator.

        Change the borders to any color you like, there are still a huge amount of computer users that shouldn't be computer users under the current OS choices.

    Just get it to vibrate around like those horrible "you're the 99999th visitor!" pop-ups, and anyone would click whatever to get rid of it. Furthermore, you could change it to one of those "are you stupid?" pop-ups, that the "no" button moves around. There are a zillion ways to get someone to click the button you want.

    These guys are pointing this out, because they want to sell symantec products. Thats the only reason why this article came out. It's the only reason why Symantec released this statement. They want to put the message out there that "You're not secure without Norton"

    This is a corporate propaganda directive, possibly directly from the CEO him/herself. "Find something, and lets use it to make us money"

    The old anti virus company making viruses, just to fuel sales... has come true. They dont have to release the viruses though, but simply they figured something out, and to tell the world that something.

    Profit at all costs.
    • Actually, I feel quite secure with my XP SP2 behind a well configured router, without any anti-virus. I don't think I've got any viruses on it, but if I do, it doesn't feel as slow as a computer running Norton.

    • These are the same guys that sell Mac OS antivirus through fear [slashdot.org] and can never have enough access [informationweek.com] to the Vista kernel.

      Microsoft has some big problems with security, but Symantec is sickeningly desperate. I used to depend on Norton/Symantec to keep my computer from dying. Now I just want the company to die (as desperate companies sometimes do). They sound like one big Mad Money "sell-sell-sell" button, just wanting to sell something to the public for whatever they use.

  • Hey -- this is simply a setuid root shell, a potential security hole as old as Unix. Apparently programmers never learn from experience. When I administer a system, a program which runs other programs based on user input doesn't get to be setuid root.

    I don't use Vista so I don't fully understand. Do the colours of the popups provide security-related information? Seems pretty ridiculous and unfair, considering I'm not the only person in the world who is colourblind...
  • So basically Symantec is saying:
    1) Sneak in a file with a virus payload
    2) Execute that file, triggering the UAC
    3) User blindly clicks "OK"

    Of course, the point of UAC is to prompt the user when something is trying to run that requires admin privledges. Users know that when they see this box randomly pop up that something unusual is happening.

    Unless they just said to install some software or tried to change a setting themselves, seeing this pop up when they visit
  • Wow...
    If I can infect your system with a trojan and drop files onto your hard drive and then remotely run code, I can get you to click OK to a box that could infect your system.

    Truly groundbreaking work here. Seriously, I mean, if all I have to do to possibly infect your system, is infect your system... well hell, Vista will probably be recalled!

    As usual, TFA doesn't live up to the summary hype. But that won't stop the MS haters from jumping on board with a "See! It's broken!"

    My problem with UAC is that I bought a new computer recently, with Vista pre-installed and during the initial setup it prompted me to create a user account. The user account had full admin privileges. I immediately set up a lower privilege account for general webbrowsing etc, and when using that account not only do I have UAC confirmation messages, but I also have to enter a password. That is a good thing - rather like 'su' in Unix like operating systems or Ubuntu's locked screed admin method. Users just aren't going to realise the importance of what they're doing with just binary yes or no security questions. If anything with the initial account defaulting to admin, Pavlov's dog like, they're going to be conditioned to hit yes without thinking. People aren't paranoid even though people are out to get them.

    To rectify this problem Microsoft should make it clear during installation that the initial admin account shouldn't be used as the main account. This is not clear during the installation.

    Good things:

    - Internet Explorer's protected mode.
    - Making sure the heap is in a different place on each computer.
    - UAC is good for experienced or computer literate users (nobody else.

    Bad things:

    - UAC, in its present form, is just training computer illiterate people to click yes. There is an emphasis with a consumer operating system to educate the user. Not necessarily enforce (that would restrict freedom) but it should educate. All or nothing is not good.
    - Idiot reviewers thinking that an operating system is the largest contributory factor in the speed of a computer. Saying Vista is faster than XP when it's been run on a new, much faster computer, is a little like trading a saloon car for an Aston Martin and saying that the Aston Martin is faster because of the upholstery.
    • - UAC is good for experienced or computer literate users (nobody else.

      Yes and no.

      Maybe if UAC was less repetitive when first configuring Vista I'd agree, but to turn it off and then turn it back on when configured proves that computer savvyists don't need it, but afterwards it may save our butts when we'll one day accidentally run an executable but get a warning.

      Computer illiterates on the other hand, they get bloatware on IE cause they click yes to accept and run any ActiveX and certificate bs so they'll d
