Our approach to Thick Client Security Assessment

We at HackersEra take a multifocal end to end approach when it comes to the Thick Client Security Assessment.



Our team will conduct a functional analysis of the application, user functions, business logic, and application structure. Depending upon the architecture, 2-tier or 3-tier next phases are plan accordingly.


Automated Assessment

We use a proprietary tool to identify common issues in thick client software. Our security consultants use the tool to analyse the thick client's network communication, interprocess communication, and operating system interactions.


Configuration analysis

Our security consultants assess the configuration of your thick client, looking for both default configuration issues and ways for the application to get around security controls. Additionally, this assessment verifies that your software is taking advantage of the platform's security features.


Network communication analysis

Remote execution is used in many thick client attacks. When this is the case, we intercept and analyse network traffic in detail, and if necessary, reverse engineer custom protocols. Regardless of the protocol, we use a proprietary tool to intercept and modify traffic. We also write plugins to decrypt and parse packets for deep analysis using custom protocols.


Client-Side Analysis

We assess the thick client software itself using various tools, depending on the software and attacks being dealt with. Memory dumps, privilege escalation testing on IPC channels, fuzzing file inputs, and in-depth reverse engineering are just a few of the things that can be done.


Back-end/Server-side Analysis

Because most thick clients rely on server-side functionality, a successful server-side code exploit can compromise all thick clients and central data stores. During this phase, we evaluate the server software using a variety of manual and automated tools.


Report submission

Once the assessment is complete, a detailed written report outlining each observed and or exploited vulnerabilities, along with the root cause analysis and categorisation along with mitigation and confirmatory re-test certificate if the need arrives.



What really makes us stand apart is our excellent and round the clock support, making sure our clients never have to witness hurdles in the business.

Thick Client Security Assessment?

Thick Client Application Security Testing necessitates highly skilled manual penetration testers and a methodical approach. These applications are critical for internal operations and frequently contain and process sensitive data. We can help you identify vulnerabilities in thick client applications that expose your organisation to external or internal threats.



Since your thick client applications can involve intellectual property belonging to your company, you want to ensure that they are immune to reverse engineering and alteration. Without professional analysis of binary hardening mechanisms, you would be unaware of the ease with which an attacker can reverse engineer or change your client-side code. We provide the highest-quality cybersecurity services and have extensive experience analysing obfuscated and hardened software, as well as breaching security controls such as white-box cryptography.
