A netcat alternative with remote code execution.
sumit@HAL9000:~/Coding/netmog$ python3 netmog.py -h
usage: netmog.py [-h] {client,server} ...
optional arguments:
-h, --help show this help message and exit
mode:
{client,server}
client client mode: for sending commands to a remote server
server server mode: for executing commands from remote client
As you can see above, netmog has two modes — client and server.
sumit@HAL9000:~/Coding/netmog$ python3 netmog.py client -h
usage: netmog.py client [-h] -t HOST -p PORT [-s]
optional arguments:
-h, --help show this help message and exit
-t HOST, --host HOST target host
-p PORT, --port PORT the port on which the target host is listening on
-s, --shell shell mode, to use with a remote netmog serverIf you're using netmog to send commands to a remote netmog server, use the --shell flag to use it in shell mode. For example, the following connects to the remote netmog server at localhost:5050 ::
sumit@HAL9000:~/Coding/netmog$ python3 netmog.py client -t localhost -p 5050 --shell
[*] Connected to localhost:5050
[ netmog ] $ ls
LICENSE
netmog.py
README.md
[ netmog ] $ Of course, for this to work, you'll have to run a netmog server at localhost:5050. Get the instructions for that here.
You can also use netmog as a standard netcat-like utility, which is the actually default mode for the netmog client. Only thing you have to keep in mind is
Note — In this mode, pressing Enter// newline doesn't send the request; Ctrl+D// EOF does. This is done so that the request body can contain newlines.
In the following example, netmog is used to send an HTTP GET request to google.com.
sumit@HAL9000:~/Coding/netmog$ python3 netmog.py client -t google.com -p 80

usage: netmog.py server [-h] [-t HOST] -p PORT
optional arguments:
-h, --help show this help message and exit
-t HOST, --host HOST hostname to bind to
-p PORT, --port PORT the port to listen onThe netmog server binds to a mentioned host:port and keeps listening for incoming connections. Once it receives a message, it executes that as a shell command and returns the resulting output, i.e. stdout and stderr combined.
One thing to note is that here the --host argument is optional, by default it takes the value of 0.0.0.0. See the following example to see it in action ::
sumit@HAL9000:~/Coding/netmog$ python3 netmog.py server -p 5050
[*] Listening on 0.0.0.0:5050
[*] Accepted connection from: 127.0.0.1:41784
