Hello xuhw,

there are not much to explain.There is also no redirection.

Just set BP on GetModuleHandleA and trace over ret 4 and now you can rebuild the OEP bytes.

PUSH EBP
MOV EBP,ESP
ADD ESP,-10
MOV EAX,4B66A4 // <--Look EBX
CALL 00406E80
JMP 005348D4

Set BP on ret and run.

00406E80   PUSH EBX  // <-- Call 00406E80
00406E81   MOV EBX,EAX
00406E83   XOR EAX,EAX
00406E85   MOV DWORD PTR DS:[4B70C4],EAX
00406E8A   PUSH 0
00406E8C   CALL 00406DBC  //  GMHA
00406E91   MOV DWORD PTR DS:[4BB668],EAX  // <--EBX holds value of EAX before.Here you are.
00406E96   MOV EAX,DWORD PTR DS:[4BB668]
00406E9B   MOV DWORD PTR DS:[4B70D0],EAX
00406EA0   XOR EAX,EAX
00406EA2   MOV DWORD PTR DS:[4B70D4],EAX
00406EA7   XOR EAX,EAX
00406EA9   MOV DWORD PTR DS:[4B70D8],EAX
00406EAE   CALL 00406E74
00406EB3   MOV EDX,4B70CC
00406EB8   MOV EAX,EBX
00406EBA   CALL 004049D4
00406EBF   POP EBX
00406EC0   RETN <------ here

Trace over and now you have the back jump address for the JMP above to rebuild your OEP.

Thats all here.

004011A9   PUSH 4012C0			   ; VB5!
004011AE   CALL 00401122			 ; JMP to MSVBVM60.ThunRTMain

Thats all.
