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? – curiousguy Aug 19 '12 at 18:22
+1, always wondered this: where is malware when you need it?! – Luc Aug 19 '12 at 19:00
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 ;) – rath Jun 16 '13 at 12:17
@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? – NULLZ Jun 16 '13 at 22:43
Can you say me which tools you are using for the analyze? – Hidden Jun 17 '13 at 14:33

Can you supply the links with short summaries? I've looked at first ones and they all seem to be simple forums. I see now concrete links to infected files that I can download. Is it because I must register first to get access? – Val Jun 16 '13 at 12:45
@Val Malshare doesnt require registration – BlueBerry - Vignesh4303 Jun 16 '13 at 12:49
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. – Val Jun 16 '13 at 13:10
