How does the stdapi commands 'webcam_snap' and 'webcam_stream' in meterpreter session bypass webcam restrictions/privacy settings on windows? I want to know how one could replicate this for prevention and analysis or just how it works in general.

  • What do you mean by "Webcam restrictions on Windows"? Are you referring to Windows 10's Privacy Settings? – MechMK1 Nov 28 '19 at 10:13
  • Yes edited to make more clear. – sd dev Nov 28 '19 at 10:18
  • And did you verify that Meterpreter is actually able to create a picture of the webcam and doesn't just return e.g. a black image? – MechMK1 Nov 28 '19 at 10:18
  • Yes, I've tested on fully updated windows machine, even with windows defender running it bypasses. – sd dev Nov 28 '19 at 10:20
  • Alright. It might be that the Windows 10 Privacy Settings only count for "installed" applications, not any process. Otherwise you'd see every executable found on your PC in there. Or at least a set of programs that Windows 10 is aware of. But that's just me guessing. – MechMK1 Nov 28 '19 at 10:23
