    AppGuard version 3.4.2.4 is now available for download on http://www.blueridge.com/index.php/products/appguard/consumer. This addresses the issue with MBRGuard on Windows 8. There are no other changes so unless you are using Windows 8 there is no reason to upgrade. For those of you who are using Windows 8, please uninstall the previous version of AppGuard, reboot and then install the new version (and then reboot again!).

    I don't think the release notes have been uploaded to the web site yet (my fault), but they should be there later today.

    Please be patient with us over the next few days. We are in the path of hurricaine Sandy. I will try to monitor email and the forum, but given the massive power outages they are predicting I may not have reliable Internet connectivity.

    For others in the path of this historic storm, please be safe!

    Perfect timing, think I'll be upgrading this week.

    Any advice to go with Win 8? Can we/should we be guarding Metro Apps for example? I notice Tzuk is saying the AppContainer is good enough.

    Thanks

    Best of luck with that one to you and all at Blue Ridge and anyone else in this thing's path.

    Don't use flash, what's the verdict?

    Hard to tell. The video moves very quickly and the Windows prompts are in Polish but it appears to suggest that in Lockdown AppGuard still allows a rogue AV to run (via Java exploit triggered by Blackhole or termination of AppGuard?).

    Indeed. Exploit has loaded a process into memory and then LSP was been started. What a shame.

    That's what we all are waiting for.
    I can understand that it could happen if protection level was set on High, but AG was compromised while working in Locked Down mode. It's a bit weird :(
    But anyway whaterver happened I believe that devs are going to fix this soon.

    Since I know about Appguard I haven't really seen anything got past it's protection you can basically throw anything against appguard without getting infected.
    That's why I can't really believe the Video. I might take a closer look what he was doing exactly but in the end you can see Appguard getting terminated and then the rogue launches.
    Appguard has self protection (tamperguard) so actually it shouldn't be terminated.

    I wonder if it makes any difference if you strengthen protection around Java, maybe guard it with Memory protections turned on etc...

    Can anyone test this again in a virtual machine?? Would be interesting to see what the actual Problem was that got the Computer infected.
    ------------------------------------------------------------------------------------------------------------------------------------------------
    So I watched the Videos closely and it seems the first Thing appearing in Memory is a .dll file. Then he continues to paste the malicious URL in the browser and then you can see the oiginal jusched.exe being terminated and after that you can see a process called javaw.exe poping up. After some more attempts pasting the URL the rogue finally launches. It seems the malware gets through in pieces. That's why he pasted the URL over and over again.


    BTW: In the Publishers tab there's Sun Microsystems which is now Oracle and install is set to allow.

    I am wondering how it would be if process javaw.exe would be protected with EMET?

    I just tested this same FakeAV in Virtual XP.
    Protection mode: Locked down
    Allowed guarded user-space launches and ran it from the documents folder.
    It successfully terminated AppGuard; in fact it's very good at terminating most things.
    Unfortunately for Mr Malware, the BrnFileLock driver blocks it from writing its start entry, so upon reboot poor FakeAV is dead.
    Even if it didn't block writing the run once start entry, it would not have been able to launch from its user-space directory.
    RIP malware

    Well done stackz, :thumb:
    Would it be possible for you to retest in high mode ?
    Also can I ask all other appguard users, if they experience any conflicts/problems running appguard in locked down mode.I just switched to locked mode, and I'm getting 11/04/12 11:37:03 Prevented <Sandboxie Control> from reading memory of <Firefox>. every 2 seconds

    Thanks

    Stackz,
    Can you please repeat this test with EMET added and javaw.exe protected by EMET?

    Nice testing. The difference between these videos and the real world illustrated. Would be nice though if BRN commented on the termination technique and if they have any plans to address it.

    Adding SbieCtrl.exe to memory guard exceptions or to Power Apps should resolve that.

    Just follow these instructions:

    • Open the main AppGuard window and click on “Customize…”
    • Switch over to the “Advanced” tab and click on “Add” under the MemoryGuard settings.
    • Navigate to your Sandboxie install location (default is C:\Program Files\Sandboxie).
    • We will be adding the following 3 Sandboxie executables with “Write” permission:
    1. sandboxierpcss.exe
    2. sandboxiedcomlaunch.exe
    3. sandboxiecrypto.exe
    • Now switch over to the “Guarded Apps” tab and click on “Settings…” under Folders.
    • Add your main sandbox folder (the default location is at C:\Sandbox) with Read/Write permissions.

    Many thank Chris1341, unfortunately it did not make a difference

    Many thanks pablozi, but I already had those settings in place.
    It's only when switching from high to locked down, do i see the alerts every 3 seconds.

    11/04/12 14:30:54 Prevented <Sandboxie Control> from reading memory of <Firefox>.
    11/04/12 14:30:51 Prevented <Sandboxie Control> from reading memory of <Firefox>.
    11/04/12 14:30:48 Prevented <Sandboxie Control> from reading memory of <Firefox>.
    11/04/12 14:30:45 Prevented <Sandboxie Control> from reading memory of <Firefox>.
    11/04/12 14:30:44 Protection level is set to <locked down>.

    There is no apparent problems, just alerts when I open the Appguard gui.
    I have gone back to high mode. I just don;t like the idea of anything interfering with Sandboxie, but i really appreciated your advice :)

    Very strange, just put lockdown on my desktop, and not a peep from Appguard, yet it has identical settings to the laptop regarding Sandboxie.
    Will have to investigate further.

    i would like to make a suggestion for future versions. as well as showing in the log window it would be useful if you could right click on a blocked program there was an option to manage it eg. allow app to be excluded or allowed and maybe another option to block

    I've asked one of the developers to take a look. I hope to get back to you all in the next few days. Thanks to all of you for bringing this to our attention!
