Thick Client/Desktop App Pentest

Thick client and desktop applications often process sensitive data locally, making them a valuable target for attackers. Our Thick Client/Desktop Application Pentest examines both the local and network attack surface — from insecure storage and binary exploitation to protocol misuse and logic flaws.

Using reverse engineering, dynamic analysis, and protocol inspection, we identify vulnerabilities that could allow attackers to bypass authentication, escalate privileges, or tamper with business logic. Whether your app runs in an offline or connected mode, we ensure it’s resilient against real-world exploitation attempts
