halomaster Posted January 8, 2015 ID:927618 Share Posted January 8, 2015 My setupWindows 8.1 Update 1Free version of MBAE 1.05. I don't have the premium version, but if I did... Is it a good idea to shield Windows system files, such as dllhost.exe and explorer.exe? Or is it pointless to do this? Let's say I download a .jpg file that can magically exploit Windows Photo Viewer. When I open it, dllhost.exe is now running. If it's shielded, then the exploit should be blocked.

David H. Lipman Posted January 8, 2015 ID:927621 Share Posted January 8, 2015 If a JPG exploits Windows Photo Viewer, you use MBAE to monitor Windows Photo Viewer. DLLHost.exe would be ( in your scenario ) the result of a successful exploitation so that's not the solution. It is the program/utility that is exploitable and is targeted by malicious activity that gets monitored by MBAE. Link to post Share on other sites More sharing options...
halomaster Posted January 8, 2015 Author ID:927638 Share Posted January 8, 2015 It seems Photo Viewer is a .dll file (PhotoViewer.dll), not an .exe file. I will be unable to shield this app. Link to post Share on other sites More sharing options...
David H. Lipman Posted January 8, 2015 ID:927641 Share Posted January 8, 2015 It wouldn't make any sense to do it anyway. That was just your scenario. The fact is JPG is a graphic format that is ubiquitous. Therefore many applications and utilities can be associated to a JPEG by MIME or by the extension and thus would fail miserably as a vehicle for use in a exploitation attack.
