### Variation's:
1. Online: payload.txt(requires internet connection on victims machine).
2. Offline: payload2.txt(don't require internet connection on victims machine).
### Workflow:
1. Stop storing history, this helps to keep tracks clear from begining.
2. Creating temporary folder for storing exploit code and compiling it.
3. Importing, compiling and executing exploit.
4. Spawning root shell.
5. Deleting exploit code and clearing tracks.
