This was discussed in the past.  It is one of the features within Core
Impact from Core Security.  Here is an old post on the subject:

CORE IMPACT has a Python module (uses win32api)to do just that, it is
called
"Record audio file" (there is also a "play audio file" and a "grab 1 frame
from Webcam")

Basically, it uses the Windows MCI interface:

m/_win32_about_mci.asp

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/ht
m/_win32_mci_reference.asp

There is also a generic "Execute MCI string" that we commonly use to amuse
ourselves by opening/closing the CD door remotely once we've gain access
to
a target system running windows.

It should not be difficult to write your own quickly with Python and the
above reference from the MSDN

Jim, 
    In all reality you don't have to be an agent  to do this. You could just
write an exploit that when successfully executed would compromise the target
and then fetch an application from a remote site. I'm sure that things like
this have been done in the past. Hell imagine what you could do with a web
cam! ;]

    New telephones are no different I'm sure.

I started this discussion elsewhere, but I feel that there is more
experience and concern here.   When I look at BIOS settings I see config
options to disable sound cards, USB, CDROM, INTs, etc., but what about
the PC or laptop microphone?  Does disabling the sound card remove the
availability of a built-in microphone? What if I want to play mp3s but
never have the need to use a microphone? Given recent info about the US
FBIs capabilities to remotely enable mobile phone microphones
(presumably via corporate cellular service providers), what prevents my
OS provider (or distribution) and ISP from working on a way to listen in
on my office or home conversations via the microphone or the built-in
speakers?  Thoughts?
