I read what you took as proof.
It could be interesting before those functions in AM get patched.
To note some small things:
1.To compare two decrypted binary files, you would have to get a better differ for them. I suggest BinDiff. (There is hacked one in the air. Pretty good tool with IDA Pro 6.6.) Just load those seperately in IDA, and store the results to idbs, and close one, "Diff" the other generated. It would show you which functions doesn't match.
2.Hope you could get a Official SDK, at least its Signatures generated by FLAIR. Also you would better have signatures made using other libraries.
3.Find a good auto tester/attcker/ somewhat else to scan the functions. Not very pratical cause the proper one is difficult to be find. However finding a ROP tool for such need isn't so hard, just try them only if you know how to exploit ROP Gadgets.
And, good luck to you, if you decided to do so.
