I used Ollydbg to attache the process but failed to trigger the exploit .Everytime I did such work ,I can only see the collapse of Firefox.The only way could I trigger the shellcode is in such kind of method.First , open a firefox.Second, open Ollydbg and open an excutable firefox process,run it.Third it will present a new windows and the ollydbg stops at address 7c92e54 .Forth, open the Html ,trigger the shellcode but the Ollydbg can show nothing…….Windbg the same……I wonder if you can tell how to deal with it.
