How to Hack a Wi-Fi Network: WPA/WPA2 PSK Attack Methodology

Wi-Fi hacking is often synonymous with WPA/WPA2 PSK attacks, one of the most popular ways hackers attempt to compromise wireless networks. These attacks take advantage of weak pre-shared keys (passwords) by capturing a crucial piece of data known as the 4-way handshake  during the network authentication process. Once captured, this data can be cracked using dictionary or brute-force attacks to reveal the network's password. The attack methodology involves several steps, starting from identifying the target network, capturing traffic, and forcing devices on the network to disconnect (using a deauthentication attack), all the way to cracking the captured handshake with tools like aircrack-ng . By generating custom wordlists with tools like CUPP  and rsmangler , attackers can tailor their brute-force attempts to the specific target. This guide will walk you through the entire process, detailing the tools, techniques, and commands used, while also explaining how to secure your own net

How to Prevent SQL Injection Attacks: A Comprehensive Guide

SQL Injection (SQLi) is a dangerous security vulnerability that threatens web applications by allowing attackers to manipulate databases through malicious inputs. It can result in unauthorized access to sensitive information, data corruption, or even complete system compromise. This guide outlines SQL Injection, its mechanisms, real-world cases, and practical steps for preventing such attacks. Table of Contents 1. What is SQL Injection? 2. How SQL Injection Attacks Work 3. Step-by-Step Guide to Preventing SQL Injection 4. SQL Injection Prevention Best Practices 5. Conclusion 1. What is SQL Injection? SQL Injection is a method where attackers exploit a web application by inserting malicious SQL code into an input field, gaining access to a database or executing unintended commands. Web applications that fail to validate and sanitize user inputs are particularly susceptible. When a user enters data, like a username or search term, the application interacts with its database by exec

OSWE: The Review That You Should Read

  In the ever-evolving world of cybersecurity, certifications are often seen as milestones that mark one's journey from novice to expert. Among the myriad of certifications available, OffSec Web Expert (OSWE) stands out as one of the most challenging and respected. If you're considering pursuing OSWE, or if you're simply curious about what it entails, this review is for you. What is OSWE? OSWE, or OffSec Web Expert, is an advanced certification offered by OffSec, a renowned organization in the cybersecurity community. The certification is aimed at professionals who want to demonstrate their expertise in conducting white-box penetration testing on web applications. Unlike black-box penetration testing, where the tester has no prior knowledge of the target, white-box testing involves having access to the application's source code, allowing for a more thorough and in-depth analysis. The OSWE certification is not just another feather in your cap; it's a rigorous test of

  CVE-2024-37900: XSS through Attachment Filename in XWiki Uploader In the world of cybersecurity, finding vulnerabilities isn't just about identifying problems — it's about making systems safer for everyone. Recently, I discovered a Cross-Site Scripting (XSS) vulnerability in XWiki, an open-source wiki platform. This post explains CVE-2024-37900, how it works, its implications, and the importance of contributing to open-source communities. What is XWiki? XWiki is a free and open-source wiki software platform written in Java, designed for extensibility and enterprise use. It features WYSIWYG editing, document import/export, annotations, tagging, and advanced permissions management. XWiki supports storing structured data and executing server-side scripts in languages like Velocity, Apache Groovy, Python, Ruby, and PHP within wiki pages. Users can define custom data structures, attach them to documents, and query them using XWiki's query language. Its robust extension ecosyst
