Steganography is a technique of hiding  a secret message within an ordinary message and extracting it at the destination to maintain confidentiality of data. An attacker can use steganography to hide messages such as  source code for hacking tools, usernames and passwords, plans for future attacks and many more. Below i will explain how could this achieved in practice using Snow tool. 1)Create a simple txt file and browse to snow directory with command prompt and write the command below.   2)After creating the encrypt txt file you can open it and observe the differences.Have they got the same size?No. What else you could see ? 3)Decrypt the file and extract the hidden message.

Netcat is simple command-line utility available for linux,Unix and Windows platforms. It is designed to read information from connections using TCP or UDP and do simple port redirection on them as configured.However Netcat has one drawback and an attacker can exploit it by passively sniffing your communication channel. Cryptcat=Netcat + Encryption (TwoFish) Instead of Netcat you can use Cryptcat to secure your communication channel.You are not the only one who can use it as well as attacker can do that.See the pictures and observe the difference in Wireshark
