your program is protected with some kind of exe stealth and Neolite 2.0,here is your oep:

load program in olly,you shoud be here:

00597800 > 40 INC EAX
00597801 92 XCHG EAX,EDX
00597802 90 NOP
00597803 4A DEC EDX
00597804 92 XCHG EAX,EDX
00597805 B8 901C5900 MOV EAX,CATCount.00591C90
0059780A 50 PUSH EAX
0059780B C3 RETN

push F8,execute RETN and you land here:

00591C90 . BA 0C785900 MOV EDX,CATCount.0059780C
00591C95 . 52 PUSH EDX
00591C96 . C3 RETN

F8 execute RETN and you are here:

0059780C BA 901C5900 MOV EDX,CATCount.00591C90
00597811 B8 60BE00B0 MOV EAX,B000BE60
00597816 8902 MOV DWORD PTR DS:[EDX],EAX
00597818 42 INC EDX
00597819 42 INC EDX
0059781A 42 INC EDX
0059781B B8 B052008D MOV EAX,8D0052B0
00597820 8902 MOV DWORD PTR DS:[EDX],EAX
00597822 4A DEC EDX
00597823 4A DEC EDX
00597824 4A DEC EDX
00597825 FFD2 CALL EDX-----------------------> trace this call

00597829 42 INC EDX
0059782A 7A F2 JPE SHORT CATCount.0059781E

now F8 till 00597825 CALL EDX, then F7 step into call, you land here:

00591C90 . 60 PUSHAD
00591C91 ? BE 00B05200 MOV ESI,CATCount.0052B000
00591C96 . 8DBE 0060EDFF LEA EDI,DWORD PTR DS:[ESI+FFED6000]
00591C9C . 57 PUSH EDI
00591C9D . 83CD FF OR EBP,FFFFFFFF
00591CA0 . EB 10 JMP SHORT CATCount.00591CB2
00591CA2 90 NOP
00591CA3 90 NOP
00591CA4 90 NOP
00591CA5 90 NOP
00591CA6 90 NOP
00591CA7 90 NOP


now look at register and notice the value of ESP its 0012FFC0 in my case.

click on dump section,ctrl+G and in expression to follow box select 12FFC0,you are here:

0012FFC0 27 78 59 00

now highlight these four value and right click,select breakpoint hardware,on access----> Dword

now shift+F9 once and you land here:


00591DDF .-E9 C8F6F4FF JMP CATCount.004E14AC-----> execute this jump and you are at OEP
00591DE4 FC1D5900 DD CATCount.00591DFC

execute jump at 00591DDF with F8 and you land at oep:

thats it now you can fix IAT withImprec.
