I wish to analyze the changes made by a specific virus. For example, Win32.Sality.
Where can I get the sample of this, or other similar, malware for testing?

    And do AV editors in general have some official feed for malware?

  • I'm sure you can find some scene websites with virus samples, I can't remember the title exactly but there was one talk at Chaos Comm. Conference who was talking about that. Alternatively I can just give you my old hard drive ;)

  • @val you seem to be under the impression theres a complete collection of all viruses ever somewhere? AV vendors might have something like that but the storage requirements would be intense. Regardless your wont be getting a copy from anyone. Also. Ecair test file?

    Would be the first time ever that my spam folder contains malware.

virusshare.com is another great repository of malware samples, having a huge number of samples. A snapshot from the website's homepage:

enter image description here

Access is by invitation only, so you will need to drop a mail to the site admin.

Another good resource that I know of- www.deependresearch.org

  • Tekdefence is the only simply browsed. Openmalvare responds with some list if I enter "windows" into the search windows. I would not find these sites without your help. This trick, with entering "windows" into MD5 window, however, does not succeed with Malshare. It seems really demanding exact MD5 keys, which I do not have without having samples first.

Github now contains massive repos of malware. The one I linked is but an example.
