i managed to overwrite EIP with my A's and eventually with a JMP EBP from my USR32.dl file and even managed to put in my breakpoints where my shellcode was supposed to go, everything worked with Ollydbg. but I kept failing at the shellcode which I generated with Msfpayload. I spent the rest of the day playing around with different shellcodes trying to get the blasted thing to work, I played with different connecting shellcodes, vnc injects encoders and even filtering out bad characters, padding with Nops and the blasted thing still wouldn't work.
Could anybody please provide me with any tips for shellcode. I understand the difference between types of shells e.g bind and reverse but the different encoders are throwing me off. could I have just missed a bad character somewhere. Any help would be much appreciated thanks
