Secureroot's thick client penetration testing services help banking, trading, defense, and enterprise software vendors find security weaknesses in Windows, Linux, and macOS desktop applications. Binary analysis, reverse engineering, client-server protocol testing, and local privilege escalation testing. ISO 27001 certified. Trusted by MoJ Kuwait.
Thick client penetration testing is a security exercise where certified ethical hackers test desktop applications – Windows .exe, .NET applications, Java desktop apps, Electron apps, native macOS and Linux software – to find security weaknesses. Unlike web applications that run almost entirely on a server, thick clients run substantial logic on the user’s machine – making them vulnerable to local attacks, reverse engineering, and tampering that web apps simply can’t experience.
Thick client testing requires methodology web app pen testers can’t apply. The attacker has direct access to the binary on their own machine – they can decompile it, modify it, debug it in memory, intercept its communication, and tamper with local data. Trust boundaries are inverted compared to web apps: the client is in the attacker’s hands. Common vulnerabilities include hardcoded credentials in binaries, weak encryption of local data, insecure client-server protocols, missing certificate pinning, and DLL injection paths.
If your business depends on a desktop application – trading platforms, banking software, ERP clients, healthcare records software, defense applications, or enterprise software products – thick client pen testing is essential. RBI requires it for trading platforms. Banks require it for desk-side banking applications. Defense systems require it for any custom software. Software vendors selling enterprise products need it before customer deployments. Thick client testing is the only way to find vulnerabilities specific to the client-side execution model.
We follow OWASP Testing Guide, NIST SP 800-115, PTES, and binary analysis frameworks. Every thick client engagement runs through these six steps – covering binary, runtime, communication, and local-system attack surfaces.
We catalog the application’s architecture: language (C/C++, .NET, Java, Electron), packing/obfuscation, dependencies, file system footprint, registry usage, network protocols, and authentication mechanisms.
We disassemble and decompile the binary using IDA Pro, Ghidra, dnSpy, JD-GUI – identifying hardcoded secrets, weak crypto, anti-debug measures, license logic, and exploitable code patterns before runtime testing.
We test the running application with Frida, OllyDbg, x64dbg, Process Monitor, Process Hacker – observing memory, DLL loading, file/registry operations, and runtime behavior under attack conditions.
Senior consultants intercept and manipulate all network traffic using Burp Suite, mitmproxy, Wireshark – testing certificate pinning, protocol security, message tampering, replay attacks, and server-side trust assumptions.
Every finding documented with exploitation steps, screenshots, modified binary samples, intercepted traffic captures, CVSS scoring, business impact, and code-level remediation guidance.
Once your team patches the findings (typically via IaC), we verify the fixes at no extra cost. Engagement only closes when every critical and high finding is actually fixed.
