Russinovich Says, Expect Vista Malware 193

Posted by kdawson from the UAC-be-damned dept.
Hypertwist writes "Despite all the anti-malware roadblocks built into Windows Vista, Microsoft technical fellow Mark Russinovich is lowering the security expectations, warning that viruses, password-stealing Trojans, and rootkits will continue to thrive as malware authors adapt to the new operating system. Even in a standard user world, he stressed that malware can still read all the user's data; can still hide with user-mode rootkits; and can still control which applications (anti-virus scanners) the user can access. From the article: '"We'll see malware developing its own elevation techniques," Russinovich said. He demonstrated a social engineering attack scenario where a fake elevation prompt can be used to trick users into clicking "allow" to give elevated rights to a malicious file.'

      Actually, I'm really quite surprised by this.
      Quite surprised by what, that programs running in user-mode can still access the current user's data and programs in their home folder? Hardly news.

      (I was slightly confused by the statement that programs "can still hide with user-mode rootkits", though -- surely if a rootkit is running with LUA privs, it wouldn't be able to hide itself? I thought the whole point of a rootkit was that it allows malicious programs to maintain root (i.e. highest privilege) access undetected, which would make "user-mode rootkit" a bit of a contradiction in terms, unless I'm misunderstanding somewhere...?)

      (And whilst I'm posting, "...a social engineering attack scenario where a fake elevation prompt can be used to trick users into clicking "allow" to give elevated rights to a malicious file"? If it's a prompt that will give a malicious program elevated rights when the user clicks 'allow', what part of it is fake? Surely a fake/spoofed dialogue box wouldn't *actually* be able to grant elevated rights (pretty much by definition); and the text in the *real* elevation prompts can't be changed, since they run in 'secure desktop' sandbox mode, no?)

A new OS with the security enhancements removed and untested code running in "every user is a superuser" mode, just like XP without the 6 years of bugfixes. Don't tell me XP has limited accounts; using XP under a limited account takes more effort than using Linux ever did.

        The only thing keeping the malware writers away from Vista so far is its piss-poor market penetration, not its security enhancements.

            I had already addressed that.

            I had said:
            "Any file that is NOT accounted is suspect and can be individually evaluated. Most of them should be data files that are not executable."

            Again, you should be able to automatically validate the system files, then you manually check the others. Those others include the config files, user files and so on.

            In such a system it is generally quite a bit less work actually to do a reinstall and reconfiguration than combing all the files with the kind of comb you need to catch all things evil.

            If that were correct than your newly installed box would be cracked as soon as those user files were restored.

            And, yes, they will need to be restored.

            So, in EITHER case those files will have to checked for "all things evil".

            But in my scenario, the box is validated FASTER and you can identify the files that were added/replaced.

            More importantly, you can validate whether the box WAS compromised.

            It's like trying to find the proverbial needle in the haystack, except that the needles have been deliberately hidden and you don't know how many there are - and if you miss one, you lose.

            I take it that you don't work on Linux boxes much.

            There are a finite number of files on the box. And EVERYTHING is a file.

            The more of them that you can automatically validate, the smaller the number of files that you have to search through. This isn't magic. It's something called "Computer Science".

            In your scenario, you rebuild the box, restore the users' files ... and you've just been compromised again.

    People sometimes talk like strong enforcement of Unix-style permissions is sufficient to provide local security. I find that argument totally unconvincing. Yes, it's nice to have the confidence that with modern OSes like Linux, OS X, and (probably) Vista I won't end up like the old Windows where you have to reformat a disk to try to clear the deeply dug in roots of some spyware crap from the system, but there's still the pretty damn big issue of all my data. Namely, having to reinstall the OS would be a pain, and I'm glad I don't have to waste an hour doing it, but losing all my data (documents, photos, music, and to a lesser extent application preferences) would be devastating. The data on my PowerBook is my life, and the reassurance that at least I don't have to reinstall OS X would be cold comfort at best. True, I do make a monthly backup onto an external drive that is normally unplugged (and thus out of range of rm *ing attacks), but probably most users don't follow this practice. Besides, a subtler virus could just silently corrupt my data over a period of months, so that I don't notice what's going on until my backups are no longer any good!

    There is a solution to the problem, but it requires a deep rooted change in how things are done. What I propose is that we shift from permissions by user to permissions by application. Right now, any app that my user launches can erase any of my files. That's ridiculous! Much more logical would be allowing me to decide which subset of my files each app can user and how. So, for example, I would let FireFox write downloads to my desktop and its preferences and caches to subfolders of the Library, but I wouldn't want it to be able to erase any of my other files under any circumstances. In fact, most of the time I don't even want FireFox to be able to read my local files, but I'd be willing to put in a password to let it do on a time limited basis so during uploads and the like.

    Basically, what I'm proposing amounts to sandboxing every app. This may seem harsh, but why not do it? What's the advantage of letting any app destroy any of my files? Make them at least beg me for permission first, I say!

    So, that's what's on my wishlist for the future of OS level security.

      It's not new either. And it does what you want it to do. However, it's a royal pain in the ass to configure, because you need to figure out what every application should be able to do. It's definitely not something for a newbie, and probably it will be long before such a thing is usable by normal people.

      Also, I doubt it'll work well for Windows. For Linux sure, distributions would just have to provide the SELinux security settings for the packages. But for Windows? Who provides the list of

      Malware writers are not interested in corrupting your data, what do they have to gain from that? Maybe a small minority who just want to mess with people would actually bother.

      "rootkit" is often, stupidly, used as a term for what the old school virus writers call "stealth".. intercepting api calls and falsifying the result to hide something.

      they usually only do directory stealth.. the most trivial form..

      although I suppose there have been a few rootkits that did full stealth.. actually hiding modifications that have been made to a file.

      Full stealth comes in two forms:

      * remove info to be hidden on open / replace info to be hidden on close; or
      * direct updates of the buffers returned

    I have yet to be convinced that Vista itself isn't actually malware. Here is my reasoning:

    1. Usually malware comes bundled with something that I am interested in actually using. I was kind of interested in trying the aero interface of Vista, so I installed it. After doing that I noticed weird things with my computer (lockups, hard drives failing to read and write) -- a sure sign of malware.

    2. After installing Vista, my system tends to be slower. This is a clear indication of malware being on my system.

    2. Strange windows keep popping up telling me messages I am not interested in. This tends to happen also when malware is installed on a computer.

    There are several other issues, but these are the main ones. I looked at some websites describing malware, and according to security experts, these are key factors indicating that its highly likely I have some malware on my computer. I think I will have to get rid of Vista becasue not only will it eventually allow for malware to run inside of it, in fact, it IS malware!!!

      2. Yes, we're all aware that Vista requires higher system requirements than XP or Linux to run smoothly. Whoop-de-do. However, they're not as high as people pretend and Vista works well on my ex-boyfriend's 3 year old Sempron.
