Let's test our signature detection script against our polymorphed binary. Run the following steps exactly as you see them:

1. In the first Terminal tab, type the following command:

$ ./sigDetect.py ch10-revshell64-poly

2. In the second Terminal tab, type the following command:

$ less non-poly-output*

3. Use the down arrow on the keyboard in this Terminal tab to navigate to the *** OBJDUMP EXECUTABLE *** section of the output.
4. Review this output.
5. In the third Terminal tab, type the following command:

$ less poly-output*

6. Use the down arrow on the keyboard in this Terminal tab to navigate to the *** OBJDUMP EXECUTABLE *** section of the output.
7. Review this output, and compare it with the output of the non-polymorphed version of the output.
