I wanted to analyse some malware but I'm stuck with the registry of windows, and was wondering if some of you could help me to understand some of it.

It actually modified some values in the registry such as:

> HKLM\SYSTEM\ControlSet001\Control\ServiceCurrent\: 0x0000000A
> HKLM\SYSTEM\ControlSet001\Control\ServiceCurrent\: 0x0000000C
> HKLM\SYSTEM\CurrentControlSet\Control\ServiceCurrent\: 0x0000000A
> HKLM\SYSTEM\CurrentControlSet\Control\ServiceCurrent\: 0x0000000C

Which I don't understand at all, and this:

If someone could help me with those values, that would be great!

What exactly do you need? –  user3463 Feb 16 '11 at 1:04
    
Why are you messing around with malware? ...Do you like it when your computer blows up? –  muntoo Feb 16 '11 at 1:17
    
I can tell you S-1-5-21-117609710-1682526488-1708537768-500 is a SID. –  Kyle Feb 16 '11 at 1:19

That malware is exploiting the Service Control Manager - Named Pipe Vulnerability.

The last entry is for the Wave Sound in the New Menu in Explorer, the malware has most likely modified that entry for the current user so that it might break the New Menu, although it's discardable...

You get +1 for knowing what OP was talking about. –  user3463 Feb 16 '11 at 7:54
    
Do you know what the values means ? or how I can know the signification of those values ? –  xabe Feb 16 '11 at 11:32
    
@xabe: ServiceCurrent is explained in that article, it's used to exploid Named Pipes as you can change their name by changing ServiceCurrent. The other value you mention is as I said in my answer. But well, wouldn't you rather want to restore these to the default and track where the malware itself is? –  Tom Wijsman Feb 16 '11 at 12:17
    
I actually would like to restore the values of those, but i don't know how I could do it because i have no save of the previous state. –  xabe Feb 16 '11 at 14:05
    
These keys ServiceCurrent and Wave Sound don't exist here. –  Tom Wijsman Feb 16 '11 at 14:19
