Thick Client VAPT

Find weaknesses inside desktop applications by testing binaries, local storage, runtime behaviour, dependencies, network communication, and backend trust.

Exfinity uses a real attacker lens to understand how application logic can be analysed, manipulated, or abused to gain unauthorised access, extract data, or affect connected systems.

The Challenges

Desktop applications give attackers direct access to installed binaries and local files. Weak obfuscation, hardcoded secrets, insecure local databases, poor cryptography, and exposed configuration can reveal sensitive logic and data.

The application may also trust the client too much. Attackers can tamper with requests, bypass business rules, manipulate parameters, or trigger backend weaknesses. Standard web or network testing does not fully cover this attack surface.

The Solution

Exfinity combines binary review, runtime analysis, storage testing, network interaction testing, and controlled validation in one thick client engagement.

Binary and Dependency Analysis: Inspect application binaries, libraries, and internal logic for recoverable secrets and unsafe trust assumptions

Local Storage and Cryptographic Review: Assess databases, files, logs, configuration, encryption, keys, and certificates.

Runtime and Network Analysis: Review process behaviour, file activity, API calls, sessions, transport security, and certificate validation.

Controlled Exploitation and Reporting: Validate confirmed weaknesses and provide evidence, business impact, and practical remediation guidance.

Benefits

Because we craft success for every problem

01

Deeper Desktop Risk Visibility

See risks that standard web and infrastructure testing may not reveal.

02

Validate Real Exploitation Paths

Understand which flaws can lead to data extraction, control bypass, or connected-system impact.

03

Protect Sensitive Local Data

Identify insecure storage, secret handling, and weak cryptographic implementation.

04

Strengthen Client-Server Trust

Find where the server relies too heavily on requests or controls enforced by the client.

05

Actionable Remediation

Give developers practical guidance based on exploitability and business impact.

What is Thick Client VAPT?

It is a security assessment of desktop applications, including binaries, local storage, runtime behaviour, dependencies, communication, and client-server trust.

How is this different from web application testing?

Thick client testing examines installed binaries, local files, dependencies, runtime execution, and reverse engineering risks that do not exist in the same form in browser applications.

What kind of issues can be identified?

The assessment can identify hardcoded credentials, insecure storage, weak encryption, unsafe API handling, client-side control bypass, and other confirmed weaknesses.

Is source code required?

Not always. Testing can be performed using application binaries, runtime analysis, and network monitoring. Source code can be included when available and agreed in scope.

What do we get at the end?

You receive a report with confirmed findings, evidence, impact, and remediation guidance for engineering and leadership teams.
