Dive into our comprehensive library of Capture The Flag (CTF) walkthroughs and technical analyses. In this section, we dissect retired challenges from platforms like Hack The Box and TryHackMe to demonstrate real-world vulnerabilities, exploitation techniques, and privilege escalation paths. These write-ups are designed as educational case studies to help you understand the methodology behind the hack, not just the solution.
Active Directory (AD) is the backbone of identity, policy, and resource management in Windows environments. It’s a distributed, hierarchical directory service that provides centralized authentication and authorization for users, computers, groups, policies, file shares, trusts, and more. Because AD is both powerful and widely deployed, it’s a prime target for attackers — and therefore absolutely … Ler mais
Introduction Windows systems come with two powerful command-line interfaces built in: CMD.exe (Command Prompt) and PowerShell. Both of these tools give users the ability to directly interact with the operating system, automate repetitive tasks, and manage system-level functionality in a way that graphical interfaces cannot. With these tools, administrators can configure services, manipulate files, install … Ler mais
Information security is enormous in scope. No single person can master every corner of it. Consider this: Suppose you want to become a developer. There are 200+ programming languages capable of producing software that someone could later debug or reverse engineer. If you spent just 100 hours on each language, that’s 20,000 hours—about 2,500 eight-hour … Ler mais
Web applications are interactive programs that run inside web browsers. Built on a client-server model, they combine a front end (what users see and interact with) with a back end (the server logic, databases, and APIs that power functionality). This architecture gives organizations the ability to deliver powerful, dynamic services that are globally accessible — … Ler mais
Networking is the foundation of IT and security. At its simplest, a network enables two computers to communicate with each other. But once you scale beyond two machines, the complexity grows. Suddenly, you’re dealing with topologies (mesh, tree, star), mediums (Ethernet, fiber, coax, wireless), and protocols (TCP, UDP, IPX, and beyond). For security professionals, understanding … Ler mais
About Android What is Android? Android is a mobile operating system primarily designed for touchscreen devices such as smartphones and tablets. Built on a modified version of the Linux kernel, it offers flexibility, scalability, and a wide ecosystem of applications. The system was initially developed by the Open Handset Alliance, a consortium of technology companies, … Ler mais
Introduction to Sessions A user session is a series of requests sent by the same client and the server’s corresponding responses over a limited time window. Web apps rely on sessions to remember who each user is and what state they’re in. Sessions let an app apply access controls, language or region preferences, and other … Ler mais
Many of us interact with Apple products daily—whether through a MacBook, iMac, iPhone, or iPad. Behind these sleek devices lies Apple’s family of operating systems, with macOS serving as the foundation for desktop and laptop computers. Though Apple’s ecosystem also includes iOS, iPadOS, tvOS, and watchOS, much of its DNA traces back to macOS (originally … Ler mais
Introduction to Windows For a penetration tester, it’s essential to have a working knowledge of different technologies. Among the most important are Windows and Linux, since these two operating systems make up the majority of the environments encountered during security assessments, whether they are hosted on-premises or in the cloud. A solid understanding of both … Ler mais
Linux Structure Linux, as you might already know, is far more than just another operating system. It is a cornerstone in the world of cybersecurity—valued for its robustness, flexibility, and open-source nature. From powering personal computers and servers to being the backbone of mobile operating systems like Android, Linux is everywhere. For anyone pursuing a … Ler mais
Intro to Web Proxies Modern web and mobile apps spend most of their time communicating with back-end services — sending data, receiving responses, and then rendering or processing that data on the client (browser, mobile app, etc.). Because so much logic now lives on servers, testing and securing those back-end endpoints is a major focus … Ler mais
Introduction Learning to deobfuscate code is a crucial skill for anyone working in cybersecurity, reverse engineering, or malware analysis. Obfuscation is a common technique attackers use to hide what their code is really doing. For example, during red team operations, you may encounter malicious JavaScript designed to look meaningless at first glance but actually used … Ler mais
