    Default Here's a preview...

    newest version here

    Purpose: detecting rootkits.

    Quick overview: when you start RootAlyzer, it performs a very quick scan of a few important places, taking about a second on modern machines. To check the full system, click on the Deep Scan tab.

    Background: Rootkits like to hide by blending into system functions and avoiding that they get listed themselves. Windows systems are quite complex though, and files and registry entries can be listed using various ways, processes are referred to in different places, and many rootkits just don't hide from all of them, but only the standard ones that hide them from the regular user. RootAlyzer goes through the file system, the registry and process related lists using various different methods, and compares the results.

    Some screenshots: to see what I'm talking about, here are some screenshots:
    • The Quick Scan screen shown when starting the appplication:

    • The drive selection when switching to the Deep Scan:

    • The Deep scan itself:

    • Properties shown for a hidden file:

    • Properties shown for a hidden registry key:

    • Properties for a hidden process:

    • More properties for a hidden process:

    The property sheets are actually a bit newer inside the release version, offering Delete/Terminate buttons.

    It's a work-in-progress (with a new project tools category available here to track bugs and feature requests), but it's already helping to easily locate some of the current malware rootkits.

    Ah yes, compatibility, should've mentioned that somewhere

    The whole file/registry stuff is NT/2000/XP/2k3/Vista only, since it compars NT native mode function results against Win32 subsystem results (no NT would mean nothing to compare against). Process stuff could work on 9x as well.

    The screenshots show XP, admitted Wouldn't see why it wouldn't work on Vista, though I didn't test it a lot there.

    Screenshots of log in next version (ignore the results shown, those are fake entries to have something visible while debugging):

    Question With W98, what are the features I shouldn't use?

    I have W98, what are the "Process stuff"? Are there any features that could be dangerous to execute under W98?

    Thanks

    Default Mebroot

    Greetings,

    Just wondering if Rootalyzer will be looking for Mebroot at some point?

    @robo: while I did expect only one line of text to show up next to each icon, no icons at all shouldn't be. I'll look at it, planing a new release regarding the post by Coronamaker this weekend.

    Regarding the broken ACL thing, that's probably not exactly a rootkit method (unless it would give itself temporary access rights while reading/writing only, and withdraw it again immediately afterwards... interesting thought...), but I'll see if I can "corrupt" an ACL in a way I could expect in the way described above, and how to report it.

    @129260: Spybot-S&D always had some basic rootkit detection mechanisms, but the latest updates improved on three important fronts there.

    Spybot-S&D usually detects threats in our database only; RootAlyzer just shows any things it identified as hidden, without relating them to known malware. So you could use RootAlyzer to detect even rootkits that are not known yet; but one of the new plugins for Spybot-S&D includes kind of a rootkit heuristics (which is not as generic though).

    In summary: use RootAlyzer if Spybot-S&D hasn't found the culprit and you're suspecting an unlisted malware.

    @bobisbob: I'll ask our samples juggler whether he has some samples of it, would have to take a look to say.
