Comprehensive security assessment for thick client applications. We perform binary reverse engineering, DLL hijacking analysis, memory credential extraction, and communication security testing with CVSS-scored findings and a free re-test.
Purpose-built attack scenarios for desktop applications, covering binary, storage, memory, and communication.
We decompile .NET, Java, and native binaries to identify hardcoded credentials, embedded connection strings, and insecure business logic in the compiled code.
We identify DLL search order hijacking, side-loading via phantom DLLs, and vulnerable library loading that enables privilege escalation and persistence.
We test anti-debugging controls, code obfuscation strength, and tamper detection mechanisms for bypass opportunities.
We extract hardcoded API keys, database passwords, encryption keys, and connection strings embedded in the binary or configuration files.
We test licensing enforcement mechanisms for bypass opportunities, including trial period extensions and feature unlock vulnerabilities.
We identify insecure coding patterns in decompiled source, including weak cryptography, insecure deserialization, and input validation flaws.
We audit SQLite databases, local files, and application directories for plaintext credentials, session tokens, and sensitive data at rest.
We examine Windows registry keys, INI files, XML configs, and JSON settings for sensitive data persistence and weak ACLs.
We dump process memory during runtime to extract credentials, tokens, encryption keys, and decrypted sensitive data held in RAM.
We identify sensitive data leakage through temporary files, crash dumps, hibernation files, and application caches.
We test password managers, credential stores, and custom encryption implementations for weak protection or key retrieval.
We verify whether sensitive data is properly cleared from memory and disk when the user logs out or the application closes.
We intercept and analyse all traffic between the thick client and backend servers for cleartext transmission and weak encryption.
We test TLS implementation for weak ciphers, certificate validation bypass, and man-in-the-middle attack opportunities.
We test session tokens for replay attacks, session fixation, and whether sessions are properly terminated on logout.
We test backend APIs and database connections exposed through the thick client for SQL injection, authentication bypass, and data exposure.
We reverse engineer proprietary communication protocols used by legacy thick clients for insecure custom encryption or authentication.
We test automatic update mechanisms for man-in-the-middle attacks, unsigned updates, and arbitrary code execution via update channels.
A structured six-phase process covering binary analysis, storage, memory, and communication testing.
We map the thick client architecture, identify all components, communication channels, data storage locations, and dependent libraries for testing scope.
We decompile managed binaries, review native code with disassemblers, and identify hardcoded secrets, insecure configurations, and vulnerable components.
We audit all on-disk storage, Windows registry keys, and configuration files for sensitive data persistence and improper access controls.
We dump and analyse process memory during runtime for credentials, tokens, encryption keys, and decrypted sensitive data held in RAM.
We intercept and test client-server communication for protocol vulnerabilities, TLS weaknesses, and session management flaws.
We deliver a CVSS-scored report with proof-of-concept evidence and CWE mapping. Once you remediate, we re-test all findings at no additional cost.
Trading terminals, banking workstations, and financial desktop applications handling sensitive transaction data that requires protection against memory extraction and credential theft.
SAP, Oracle, and custom ERP clients with thick desktop interfaces connecting to backend databases, requiring assessment of hardcoded credentials and communication security.
Clinical workstations, SCADA HMIs, and industrial control interfaces running as thick client applications that need protection against DLL hijacking and privilege escalation.
