This is the second article in a series about using the Olly. Dbg, a 3. 2 bit assembler level analyzing user mode debugger for Windows. In part one of this tutorial we covered In this article we will cover the following subjects Methods for directing code execution in the debugger. When you are writing an exploit you are going to need to be able to execute the code in your target application in a variety of different ways, to give you the appropriate amount of control to monitor the code and memory closely when needed. You may want to run normally at one point, to go step by step through each individual instruction at another, and sometimes to have it run quickly to a particular point allowing you to take control once that point is reached. Luckily, this is all possible via the use of a debugger by using breakpoints as well as the various methods for stepping through code.

Lets start by learning how to step through code. If you havent already, start up Olly. Pages 2.1 Ipa Cracked. Dbg and open vulnserver. Execution should automatically pause at the program entry point. In the top left hand pane of the CPU view you should see the instruction PUSH EBP highlighted. Take note of the top entry on the stack bottom right hand pane as well as the value of the ESP and EBP registers in the top right hand pane, then try hitting the F8 key, just once. The F8 key is a shortcut key for the Step over operation, which allows you to advance forward one instruction, while NOT following any function calls. The significance of that will become clear in a moment, but for now, you should have noticed that since executing that PUSH EBP instruction, the value held by EBP has been added to the top of the stack and the value of the ESP register has decreased by four. In addition, the instruction following PUSH EBP in the top left hand pane, namely MOV EBP, ESP, should now be highlighted, and two registers, ESP and EIP have their values highlighted in red to indicate that they have changed. Take note of the values of the EBP and ESP registers, and hit F8 once more. The EBP register will change to match that of the ESP register, and the EBP and EIP registers values will be highlighted in red. What this red highlighting of values is indicating is that this particular value changed during the last operation. Press F8 two more times until the CALL DWORD PTR DS lt msvcrt. Now press F8 once more and execution should advance to the following instruction of CALL vulnserv. What happened here We just ran a CALL instruction, which is intended to be used to temporarily redirect code execution to another location within the programs memory space, yet the debugger didnt move to this new section of code, as we might have expected it to do. What actually happened here is that the F8 or Step over key, indeed stepped over this CALL instruction. It ran the code specified by this CALL instruction and paused the program in the debugger once more after it was done and execution had returned to the instruction immediately after the CALL. So what do we do if we want to actually follow the debugger into the code specified by one of these CALL statements We use the Step into command, which uses F7 as its shortcut key. Use the F7 key now, with your debugger selecting the instruction CALL vulnserv. The debugger will follow through to the instruction in vulnserver at the memory address 0. You can now follow along with the code referenced by that CALL instruction. So the difference between the Step over and Step into commands is that one steps over CALL statements preventing you from having to go through the code there if you dont want to and the other steps into them, allowing the CALLed code to be viewed. Where did I come from Exposing your history. Olly. Dbg keeps a history of the last 1. CPU window, so if you have stepped into a CALL statement, or followed a JMP and you want to remind yourself of the previous code location, you can use the plus and minus keys to navigate through the history. Try the minus key now, the CPU view should then display the CALL instruction that you just executed. Use the plus key to come back to the current instruction. Note that this little trick only allows you to view instructions that have actually been displayed and tracked in the debugger. You cant let the program run, generate a crash and then use the minus key to check the instruction just before the crash occurred, nor can you let your program run until it hits a breakpoint and then step back from there. If this type of functionality interests you, you can use the Run trace capabilities of Olly. Dbg, which I will cover later in this section. Animation. If you want to step through your code in a controlled fashion, but dont like the thought of having to hammer quickly at the F7 or F8 buttons, you can take advantage of Olly. Dbgs animation capabilities. Press Ctrl F7 for Step into animation and Ctrl F8 for Step out animation. This will step through the code rather quickly, allowing you to pause once more by hitting the Esc key. You can then use plus and minus keys to step through the history of your animated session. Try hitting Ctrl F7 now to do some step in animation, and then hit Esc when you are done. Now use the plus and minus keys to navigate through your execution history for a bit, until you are comfortable with how this works. Setting breakpoints. Up until now we have maintained more or less manual control over how the program is executed, with us having to either approve each instruction in advance, or having to let the instructions run in a semi automated fashion with us hitting Esc hopefully at the right time when we want the program to stop. What if we want to stop the program at a particular point in the middle of its execution though The step by step method will be too slow there are a lot of instructions in even the simplest program, and the animation method will be too imprecise. Well, to allow us to stop at a point of our choosing, we can use breakpoints, which are essentially markers on particular instructions in the code that tell the debugger to pause execution when one of those instructions are about to be executed by the CPU. Lets try setting one now. First of all, use the View Executable modules menu option to bring up a list of executable modules loaded with vulnserver. Double click on the vulnserv entry to open this view in the CPU window we are doing this because its possible that our previous animation session brought another module to the fore. Now right click in the top left hand pane of the CPU view and select Search for All referenced text strings. See the following screen shot. Fashion Show Games For Girls. Double click on the entry that has the text Welcome to Vulnerable ServerEnter HELP for help. CPU view see the selected entry in the screenshot above. Now, with this instruction highlighted in the CPU View, hit the F2 key, which is used to both set and clear breakpoints.
