Thick Client & Desktop App Testing

Security testing of Windows, macOS, and Linux desktop applications — the fat clients that still run critical business processes.

Overview

Desktop and thick-client apps handle sensitive data and privileges but rarely get the scrutiny web apps do. We test the binary, its local storage and IPC, and the traffic to its backend — finding the insecure storage, weak crypto, and privilege issues attackers exploit on the endpoint.

What we cover

The ground a typical engagement covers — always tailored to your scope.

Binary analysis, reverse engineering, and tampering

Insecure local storage, registry, and config secrets

Inter-process communication and DLL/dylib hijacking

Client-server protocol and backend API testing

Privilege escalation and update-mechanism security
