⚔️Attacking Common Applications

🎯 Module Overview: Comprehensive methodologies for identifying, enumerating, and exploiting the most prevalent applications encountered during penetration testing engagements.

Module Introduction

During penetration tests, we frequently encounter the same applications across different environments. This module covers systematic approaches to attacking the most common applications, focusing on practical exploitation techniques and professional methodologies that deliver consistent results.

Key Focus Areas:

• Discovery & Enumeration - Identifying applications and gathering intelligence

• Vulnerability Assessment - Known CVEs, misconfigurations, and default credentials

• Exploitation Techniques - Proven attack vectors and payload delivery

• Post-Exploitation - Privilege escalation and persistence within applications
