I was wondering if it was possible to create a python script that is able to capture and replay the instructions executed by a windows program for in depth analysis.
Here is an example of how you could use the pyDbg library in Python to create a basic script that captures and replays the instructions executed by a Windows program:
import pydbg def main(): # Create a new instance of the pydbg class dbg = pydbg() # Attach to the process of the target program pid = dbg.attach("program.exe") # Set a breakpoint at the entry point of the program entry_point = dbg.func_resolve("program.exe", "main") dbg.bp_set(entry_point) # Start the debugging loop dbg.run() # Once the program has exited, print the instructions that were executed print("Instructions executed:") for instruction in dbg.instructions: print("0x%08x: %s %s" % (instruction, instruction, instruction)) if __name__ == "__main__": main()
As the program runs, the script will capture the executed instructions and save them in a list. Once the program has exited, the script will print out the executed instructions. Note that this is just a very basic example, and it is not robust enough for a real-world use case. In a real-world application, you need to consider factors such as handling multiple threads, exceptions and system calls, and more.
