Seven years later Microsoft got around to partially fixing the issue with a patch, but it only prevents attackers from relaying back to the originating system. However, it wasn’t until 2001 that Sir Dystic publicly released a tool that could be used to perform practical attacks. Based on my five whole minutes of wiki research I now know that the issues that allow smb attacks to be succesful were identified as a threat in the late 90’s. In summary, an SMB Relay attack can be loosely defined as the process of relaying SMB authentication from one system to another via a man-in-the-middle (MITM) position. Using Metasploit Modules to Relay Authentication.Using Metasploit Modules to Capture and Crack Hashes.Using SQL Server to Iniate SMB Authentication Attacks.Below is a summary of what will be covered in this blog: I will also provide some practical examples that show how to use new Metasploit modules to gain unauthorized access to SQL Servers during a penetration test. In this blog, I’ll provide a brief overview of SMB Relay attacks and show how they can be initiated through a Microsoft SQL Server.
