  Wireshark Basics for security and analysis.   Wireshark is a powerful and widely-used network protocol analyzer that captures and displays data packets flowing through a network in real time. It allows cybersecurity professionals, system administrators, and developers to see what's happening at a micro level in their network. Originally developed as Ethereal, Wireshark supports hundreds of protocols and runs on Windows, macOS, and Linux. Its graphical interface makes it user-friendly, while also offering advanced features for filtering, coloring, and reconstructing TCP sessions. Wireshark captures raw packet data from network interfaces, which can then be analyzed for troubleshooting, performance tuning, or detecting malicious activity. What sets Wireshark apart is its deep packet inspection —it decodes protocol layers, giving insight into everything from HTTP headers to SSL handshakes. Whether you're monitoring DNS traffic, investigating suspicious packets, or debuggin...

Bash Scripting for Beginners: Learn How to Write Powerful Shell Scripts The most powerful skill that every cybersecurity analyst must know is task automation . Whether it’s scheduling scripts, analyzing logs, securing systems, or executing penetration tests, task automation makes cybersecurity professionals more efficient and saves valuable time . Imagine you are a cybersecurity analyst and you have to scan thousands of logs manually, or executing repetitive commands one by one—sounds exhausting, right? But what if I told you that cybersecurity experts can do hours of work into few seconds? That’s the magic of Bash & Shell Scripting, and today, I’ll show you exactly how it works in real time scripting example. Hey everyone, this is Md. Jashim Uddin with you all, —where we will break down cybersecurity concepts into easy, actionable steps. One of the most common tasks for cybersecurity analysts and ethical hackers is automating repetitive tasks—whether it's log analysis, p...

  MikroTik Network Security: How to Prevent ARP Spoofing and DNS Attacks   Understanding ARP Spoofing and DNS Spoofing        ·         ARP Spoofing: Attackers send fake ARP messages on the network to associate their MAC address               with an IP address (e.g., your gateway). This allows them to intercept, modify, or block network traffic (man-in-the-middle attacks). ·          DNS Spoofing: Attackers alter DNS queries to redirect users to malicious websites by sending false DNS responses or poisoning the DNS cache.  Here we divide the topic for best understanding and point out those Attacks prevention techniques step by step I have made a description youtube video for this if you like can watch this too. Click link   1. Steps to Protect Against ARP Spoofing        Enable ARP Filtering and ...

  ARP Spoofing and MITM Attacks with Bettercap In the world of cybersecurity, one of the most common attack techniques used by hackers is the Man-in-the-Middle (MITM) attack, often combined with ARP (Address Resolution Protocol) spoofing. This article will explain the concepts of ARP spoofing, MITM attacks, why attackers use these methods, and how to use the Bettercap tool to perform these attacks effectively. I have made a youtube Video - Network hacking for this penetration attack. This is only for education purpose so please don't use this for any harmful activities. The author will not be liable for any bad activities.  What is ARP Spoofing? ARP spoofing, also known as ARP poisoning, is a method of attacking a local area network (LAN) by sending fake ARP messages to associate an attacker’s MAC address with the IP address of another device (such as a router or another user’s machine). This trick allows the attacker to intercept or alter traffic between devices on the...
