# Performing Thick Client Application Penetration Test
## Overview
Thick client (fat client) penetration testing assesses the security of desktop applications that run locally on user machines and communicate with backend servers. Unlike web applications, thick clients present a broader attack surface including local file storage, binary analysis, memory manipulation, DLL injection, process interception, and client-server communication. Common targets include banking applications, ERP clients (SAP GUI), trading platforms, healthcare systems, and legacy enterprise software.
## When to Use
- When conducting security assessments that involve performing thick client application penetration test
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
