What is PowerShell? A powerful scripting language and command-line shell built on the .NET framework, heavily integrated with Windows. Ideal for system administration and automation, making it a valuable tool for pentesters. Why PowerShell for Pentesting? Native to Windows: Pre-installed on most Windows systems. Object-oriented: Allows for complex data manipulation and interaction with APIs. Access to .NET Framework: Enables interaction with a vast library of classes and functions. Remoting capabilities: Execute commands on remote systems. Bypass security restrictions: Can be used to circumvent some security measures if not properly configured.

SQLDB Pentest

Pivoting for Red Teamers SQL Database & SQL Injection Pentesting Cheat Sheet SQL databases store crucial application data, and misconfigurations can make them vulnerable to SQL Injection (SQLi) attacks. This guide covers database enumeration, privilege escalation, and SQL injection techniques. Step 1: Identifying SQL Database Type Check the database type by sending payloads in the input fields or URL: ' OR 1=1 -- (MySQL, PostgreSQL, MSSQL) ' UNION SELECT 1,2,3 -- (Check column count) ' AND 1=CONVERT(int,@@version) -- (MSSQL Test) Observe the error messages for database identification. Step 2: Enumerating Database Tables & Columns Use SQL queries to extract database structure. For MySQL: SELECT table_name FROM information_schema.tables WHERE table_schema=DATABASE(); SELECT column_name FROM information_schema.columns WHERE table_name='user...
