Thick Client Security Evaluation

Thick client applications (Electron, native desktop apps, heavy clients) often include local logic, secret storage and update mechanisms — all of which can be attacked if not designed securely. We test binaries, IPC, update flows, licensing schemes and integration with backend services.

Desktop apps are frequently reverse-engineered to bypass licensing, extract secret keys or pivot to backend systems. Evaluating thick-client security reduces the risk of piracy, fraud, and backend compromise.

Companies shipping desktop tools, enterprise clients, Electron-based cross-platform apps, or products with sensitive local data or licensing constraints.

Binary analysis, code signing & verification, insecure storage, insecure IPC/localhost APIs, update and distribution channels, dependency/supply-chain checks, and backend integration points.

Findings with exploit POCs, recommended binary-hardening steps (obfuscation guidance, secure storage patterns), update verification checks, and prioritized remediation.

Typical engagements range 5–15 days depending on platform complexity and number of binaries. Pricing depends on required depth (light review vs deep reverse-engineering).

We discovered an insecure update channel that allowed a man-in-the-middle to serve unsigned updates. Fixes included code signing enforcement and server-side checks plus distribution pipeline hardening.
