    Hi everyone,

    I would like to get into malware download and submission to AV vendors but I have a question before I do. What is the best way to stay safe while downloading the samples? I figure downloading them via Sandboxie submitting them, then clearing the sandbox would keep me safe but I would like to know how y'all do it. I will not be launching the malware samples to I can most likely do it without any changes but I know the one time I do not try to be safe while doing it I may mistakenly click on it.

    If you have some type of anti-execution protection, then the malware sample cannot run if you click on it.

    Once downloaded, Zip it for further protection.

    Also, use a secure wipe utility to erase the samples after you done submitting them.

    And why do you feel the need to tinker,:doubt: with computer equipment that cost hundreds of dollars, just to supply AV vendors with is what their job is. You play with fire, you may get scorched.

    Here I use a sandboxed FF to download samples and recover to desktop.

    I test for detections with a right click scan with MBAM and if it isn't hit then upload to VT for a report then upload the sample and report to MBAM's forum.

    Then I run the sample either a default sandbox or VM and try to grab any droppers for further testing.

    After I've finished I rar the samples away with the main system always virtualized with Returnil.

    It really is quite safe and easy once you get the gist of things but I still employ images as backups and do have several hard drives that I can plug/unplug on this machine.

    To me malware hunting/testing is a great pastime and is my main use of my pc.

    My favourite exploits are the Microjoin exploits which can have some new droppers every time you run them.

    Below is a pic of the droppers from running one of those exploits harvested from a default sandbox.

    Follow Franklin's procedure, or similar, and there's no need to fear.

    Franklin's procedure is pretty good. Enable Returnil's Session Lock, Start a sandboxed browser, download into a folder that is a forced folder which will force anything in that download folder to start sandboxed should anything unexpected happen (double-click).

    You can also restrict your browsing sandbox to only run your browser and only allow it internet access. While your tweaking enable Drop Rights within Sbie. And finally you can restrict file access to prevent anything from grabbing "sensitive areas" on your computer like My Documents.

    Forced programs/folders.

    Internet, start/run access and drop rights.

    File access (blocked).

    I test (only on rare occasion for fun) in a vm running in an AppLocker protected standard Win7 account. I've always got verified recent images on hand in case but never needed them. If the malware is vm-aware, so be it; it matters not to me anyway.

    Hey ! It seems you are scared not to get infected .
    I "play with fire" and don't use any protection - I just download the sample using my IE8 in protected mode and that is it . Don't worry - Windows itself have enough protections and unless you manually execute the samples you're secure.My Windows on all computers are up-to-date to prevent cases where a malicious page can be opened. And don't worry so much , you can't loose anything . In case something goes wrong (it really can't happen if you know what you are doing) , just revert back to a recent image.

    I often DL malware every day without ANY problems.

    Many times i have to disable my AV from running as it detects quite a number. If i didn't i just keep getting intercepts and block alerts, which becomes annoying :p

    Just DL'ing them does NOT cause them to run, and as long as you don't DC them you will be fine ;) Even if i did, i have ProcessGuard and PEG to prevent them from running without my permisson :)

    It won't hurt to have Sandboxie and/or ShadowDefender or Returnil as well. I have SD but don't always enable it just to DL.
