ssh -N -L 1234:mysqlhost:3306 -N that I added just tells ssh that you're only setting up a tunnel and you don't want to start a shell on sshhost. You need a second step to actually use it to connect to a MySQL server.Ĭreate the tunnel. Want to start making money as a white hat hacker? Jump-start your hacking career with our 2020 Premium Ethical Hacking Certification Training Bundle from the new Null Byte Shop and get over 60 hours of training from cybersecurity professionals.That instruction from the Sequel Pro docs isn't quite the whole story it's just telling you how to set up a tunnel. So keep coming back, my hacker novitiates, as we explore the tools and techniques of the world's most valuable skill set-hacking! I'll do a short tutorial in the near future on running Windows from the command line that should be helpful in this type of hack. Even the registry can be altered from the command line! To do so, you need to know these commands in Windows as well as Linux. Most of our tutorials here have focused on Linux commands, but Windows can be run successfully from the command line as well, especially with PowerShell. It's important to note that a knowledge of command line commands is key to being successful in this type of hack. ![]() Success! We now have command prompt on the remote system and we own it! This should open a console that looks similar to this. Let's start the Metasploit console by typing: To start, as usual, fire up Kali and open a terminal. If we can execute CMD commands on the victim system, we cannot only run reconnaissance on it, but we can also own it with enough knowledge of the system and knowledge of Windows commands. You can use a tool such SQLdict or Metasploit's own auxiliary module, sql_login, to gain the sa password and use it in this hack. By default, Microsoft packages their SQL Server with a system administrator account named "sa" and few system admins change it. Of course, to access this SP remotely, we will need the login credentials of the system admin. ![]() This SP was once enabled by default on all Microsoft SQL Server installations, but because it was exploited by hackers so often, Microsoft had disabled it by default-but we can still access it and wreak havoc! When the system admin executes this SP, they get a command prompt on the underlying server that is hosting the database. Often, the system admin of a database will need access to the underlying server, so Microsoft provides an SP called xp_cmdshell on their SQL Server. This is code provided by the developer to help the system administrator get common tasks done. Nearly all commercial databases-MS SQL Server, Oracle, MySQL, DB2, etc.-have built-in system stored procedures (SP). ![]() So instead of getting access to the database and its data, we will use the database as an intermediary to gain access to the underlying server. In this tutorial, we will use SQL injection to get access to the underlying server. There are many ways to hack databases, and most of these techniques require SQL injection (SQLi), which is a way of sending SQL commands back to the database from a web form or other input.
