    PowerUpSQL

    PowerUpSQL

    A PowerShell toolkit for attacking SQL Server

    PowerUpSQL is a PowerShell toolkit focused on auditing, discovering, and post-exploitation activities for Microsoft SQL Server environments.

The project is aimed at internal penetration testers and red-teamers but is also useful for database administrators and defenders who want to inventory SQL Server attack surface and hunt for misconfigurations. PowerUpSQL can surface things like weak configuration flags, dangerous surface (for example, features that may enable code execution from SQL), credential material exposed in configuration, and cross-instance trust relationships such as linked servers. The codebase is implemented primarily in PowerShell, organized as a module with many discrete functions, and includes helper scripts and documentation for usage scenarios.
