Red Boxed - Ubuntu operating system that I want to log in.







 1.      Find the mac of the VM.
       Right click on the VM you want to log in => Click Settings => Click Network => Expand 'Advanced'.
You can Find the Mac address of the VM there.

Open Kali Linux and run the following commands.

2.      Find the IP address of the VM.
     By looking at the mac address we can find out the IP address. 
     In here it is 3rd IP address which matches the Mac address we have found earlier.
     IP - 192.168.8.102


3.      Find the open ports
       In here ssh and http ports are opened.



4.      Run ‘hydra’ command and obtain the password
      hydra -V -l segreto -P /root/Desktop/word_list.txt 192.168.8.102 ssh
      -V =>to display the current password that hydra is trying
      segreto => username of the VM
      /root/Desktop/word_list.txt => path to word list
     192.168.8.102 => IP address of VM
     ssh => post that we trying dictionary attack

Introduction to Encryption

What is Encryption? Encryption is like sending secret messages between parties; if someone tries to pry without the proper keys, they won't be able to understand the message. In other words, it is the process of locking up information using cryptography (Cryptography is both the practice and the study of hiding information.) Definition:  ‘ The Process of converting plain text into cipher text, something that appears to be random and meaningless ’ is called as the encryption. Process of converting cipher text back into original text is called as decryption . Terminology Original message is called as plain text/clear text.   Encrypted message is called as cipher text/encrypted text.  A Key which is a secret like a password which is used to encrypt and decrypt information.  Ciphers are the specific algorithms which are used to encrypt and decrypt data. A cipher is series of well-defined steps that can be followed as a procedure to encrypt and decrypt m

Cross-Site Request Forgery protection in web applications via Double Submit Cookies Patterns

Image
Double submission of cookies is another well-known method to block CSRF. Similar to using unique tokens, random tokens are assigned to both a cookie and a request parameter. In double-submitted cookie pattern, two cookies (for the session and for the CSRF token) are stored in the browser. This pattern is also called as Stateless CSRF Defense since the server site does not have to save this value in any way, thus avoiding server side state. In our previous method, we stored CSRF token values on the server side (text file). But here we don't do it. When a user authenticates to a site, the site should generate a (cryptographically strong) pseudorandom value and set it as a cookie on the user's machine separate from the session id. The site then requires that every transaction request include this random value as a hidden form value (or other request parameter). A cross origin attacker cannot read any data sent from the server or modify cookie values, per the same-origin
