Practical Guide for Thick Client Penetration Testing

January 15, 2026 · khukuririmal

Thick client applications remain a high risk yet often under-tested attack surface in enterprise environments. Unlike thin clients (browser-based apps), thick clients run directly on end-user systems, communicate with backend services over custom protocols, and often embed sensitive logic locally. We have covered in detail about thick client testing, methodology, attack surface etc in our […]

Thick Client Security Testing: Concepts, Attack Surface, Methodology & Vulnerabilities

January 14, 2026 · khukuririmal

Thick client applications continue to play a critical role in enterprise environments, especially within banking, finance, ERP systems, trading platforms, HR systems, OT environments, and internal administrative tools. Despite this, thick client security testing is often poorly understood or completely omitted from traditional VAPT engagements. Unlike web applications, thick clients execute significant logic locally and […]

Nmap in Internal Networks: A Practical Port-Based Cheatsheet for VAPT & Red Teaming

December 26, 2025 · khukuririmal

Inside an enterprise network, the attack surface extends far beyond web servers and Active Directory. Switches, printers, scanners, remote administration tools, virtualization platforms, and legacy services often expose ports that are overlooked in traditional assessments.From a VAPT perspective, these services represent misconfigurations and exposure risks.From a Red Team perspective, they represent control points, stealthy footholds, […]

Directory & Endpoint Discovery Without Wordlists: Smarter Recon for Real-World VAPT

December 21, 2025 · khukuririmal

Applications always disclose more than intended through responses, logic, metadata, archives and integrations. Directory and endpoint discovery has traditionally been synonymous with brute-force wordlists. Tools like Dirsearch, FFUF, Gobuster, and Burp Intruder dominate this space, relying heavily on predefined lists of common paths. While effective in controlled or legacy environments, this approach often falls short […]

December 17, 2025 · khukuririmal

Black box testing is one of the most commonly used approaches in web application Vulnerability Assessment and Penetration Testing (VAPT). However, in practice, the definition of black box testing is often misunderstood, inconsistently applied, or overly simplified based on textbook explanations.Traditionally, black box testing is defined as a testing methodology where no internal knowledge of […]

JavaScript File Analysis in VAPT: An Overlooked Goldmine for High-Impact Findings

December 16, 2025 · khukuririmal

In modern web applications, JavaScript (JS) is no longer a supporting component—it is the backbone of application logic, client-side security controls, API communication, and user interaction. Despite this, JavaScript file analysis remains one of the most underutilized yet high-yield techniques in Vulnerability Assessment and Penetration Testing (VAPT).This blog explores why JS file analysis is critical, […]
