Thick Client Application Security Testing
Desktop applications have unique attack surfaces that web scanners completely miss.
VAPT · Desktop Applications · Client-Server
Desktop applications have unique attack surfaces that web scanners completely miss.
Thick client applications — desktop software that communicates with backend servers — have a completely different attack surface to web applications. Memory analysis, DLL hijacking, local privilege escalation, insecure IPC and client-side business logic bypass are all fair game. Our thick client specialists test across all common frameworks.
Our certified professionals follow internationally recognized methodologies — OWASP, NIST, PTES, OSSTMM and OWASP MASVS. Every engagement is manual-first: real experts thinking like attackers, not just running automated scanners. We are CERT-In empanelled — every report we issue is accepted by RBI, SEBI, IRDAI and all major Indian regulators.
Every Engagement Includes
Every vector, every layer — nothing assumed safe until verified.
Local databases, registry keys, config files, temp files and caches — checked for sensitive data.
Intercept all client-server communication including custom binary protocols and encrypted traffic.
Sensitive data in memory — PII, credentials, tokens — recoverable via memory dump or process inspection.
DLL search order hijacking and unsigned DLL loading that enable privilege escalation.
Client-side authentication bypass and license check circumvention.
Decompile binaries with IDA, dnSpy, Ghidra for hardcoded credentials and algorithm weaknesses.
A proven, structured approach — from scoping to certificate.
Understand the client-server model, protocols, authentication mechanism and data handled.
Set up proxy for HTTPS traffic. Identify and bypass SSL pinning. Analyse custom protocols.
Decompile binaries with appropriate tools. Review code for security weaknesses.
Runtime testing — attach debugger, monitor file system and registry access, memory analysis.
Attempt client-side authentication bypass, DLL hijacking and local privilege escalation.
Complete findings with reproduction steps. Free retest. Security Certificate.
OWASP Top 10 penetration testing for websites and web apps.
India data privacy law compliance — gap assessment to full program.
Security leadership at a fraction of full-time cost.
