Below are the commands , to Decode and Encoded text from Base64 and Rot13. It is a handy and easy technique required in CTFs. Alternatively we can also google and use any website offering decoding of text from these two types. But in terminal we can decode it quickly and save our precious time. From Base64 we use the function base64 and option -d (for decode). $ base64 -d data.txt From ROT13 (also called as rotated 13 times) we use the function tr (for translation). the text must be echo first and piped into tr with two strings as arguments. $ echo " GUR CNFFJBEQ VF 5GR8L4QETPESPK8HTQJHRK8XSP6X2RHH" |tr '[A-Za-z]' '[N-ZA-Mn-za-m]' -574r570rm

 In Wordpress we can do a username enumeration in several ways. We can do it via Metasploit or Nmap NSE Script. But if both of these are not available or we want to use another simpler method, here is one mentioned below. A Bash Script to enumerate Wordpress usernames. Copy the below Bash code text into a .sh file. Change the website to URL to your desired URL. Change the range of user ids default is 1 to 20. Then chmod the file to make it executable ( chmod +x filename.sh)(in linux terminal) and run ./filename.sh. BASH Code:  for i in {1..20}; do curl -s -L -i http://www.your-desired-website/?author=$i | grep -E -o "\" title=\"View all posts by [a-z0-9A-Z\-\.]*|Location:.*" | sed 's/\// /g' | cut -f 6 -d ' ' | grep -v "^$"; done CYB3RTR0N , 574r570rm

In Kali linux , the keyboard shortcut to Terminal is missing by default, that was a convenience that pentesters miss the most. We had this available by default in backtrack. One way to open terminal with keyboard is to press Alt + F2 , a command window will open , and write " gnome-terminal " and press Enter. Second way is to create a keyboard shortcut permanently to the terminal. For this, we will goto Settings > Devices > Keyboard. In the shortcuts section, scroll down to the end of the list , we will find a " + " sign, that is for adding a new shortcut. We have three text boxes here to fill. 1- Name : Enter the Name for the Shortcut e.g. "Terminal". 2- Command :Enter the command for the program. In our case its terminal. The command for terminal is " gnome-terminal". 3- Shortcut :  press the buttons you want to use as a keyboard shortcut for the above command. Here it can be "Ctrl+T" or " Super+T" or y...

Hello Kali fans, I installed the famous vlc player on my kali 2.0 but unfortunately it was not executing properly and was not opening at all. So, here is a fix for that if you find yourself in the same situation. open terminal window and type hexeditor /usr/bin/vlc It will open a hexeditor of vlc file, be careful not to change anything here that you don't know of, because it can make vlc crash completely. Press ctrl+w to open the search dialog box,  Press enter for the option, to search for a string  Type geteuid in the search bar and press enter. Press tab and the cursor is now on the g of geteuid, Start writing getppid ,as it will overwrite the text, make sure to not press any other key. Dont worry if you can't see what you are writing, just make sure when you type g it is overwritten on the already written g of geteuid. Press ctrl+x to save and exit. Open VLC player it will work now. CYB3RTR0N , 574r570rm

I made Kali linux (rolling) as the primary OS for one of my systems.The problem i faced was in installation of virtual box. Regular method i.e. apt-get install virtualbox , was not working.

Below is a simple python program in linux to see if a port is open or close. #!/usr/bin/python import socket ip = raw_input("Enter the IP Address: ") port = input("Enter the Port Number: ") sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) if sock.connect_ex((ip,port)):         print "Port",port, "is closed" else:         print "Port",port, "is open" We will use which python.py to know about the location of python, so we can use it in hash bang. next we are importing the socket library. taking as input and port are self explanatory. SOCKET constants and functions are used to get socket connected to sock variable. connect_ex will throw an exception if the port is closed , and we are utilizing it to display "the port is closed" else it will be open. make it executable and run,... I am not going into details, as there are many tutorials out there to learn the basics. CYB3RTR0N
