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...

  Penetration Testing of WiFi Networks WiFi penetration testing is a structured approach to assess the security of wireless networks. The primary goals include discovering accessible networks, identifying security weaknesses, and testing network protections like password strength. Here’s a breakdown of key steps: discovery, deauthentication (deauth), and handshake capture . Best 10 Penetration Testing Tools:-   Aircrack-ng Kismet Wireshark Reaver Wifite Fern WiFi Cracker Hashcat Bettercap NetStumbler Cowpatty 1. Discovery Purpose : The discovery phase is essential for identifying all available WiFi networks and connected devices within range. This process gathers critical information such as SSIDs (network names), MAC addresses, channel usage, signal strength, and security protocols (e.g., WPA2, WPA3). Knowing these details allows the tester to determine the network’s configuration and the potential attack surface. Tools : Tools like Kismet , Airodump-ng , an...

  Understanding Mikrotik Port Forwarding Port forwarding is a crucial concept in modern networking, especially for administrators managing routers like Mikrotik. This guide will walk you through the  necessity of port forwarding , its benefits,  Mikrotik firewall rules , and its associated cybersecurity challenges. Whether you’re a network engineer or an enthusiast, mastering port forwarding is essential for optimizing your network. In this post, we’ll also discuss how to mitigate vulnerabilities and safely manage port forwarding. I have make a description Video of this purpose in youtube if anyone interested or learn more please  click here to find it out.   What is Mikrotik Port Forwarding? P ort forwarding allows remote devices to connect to services on your internal network through a router. Typically, routers block incoming traffic from the outside world to ensure security. Port forwarding creates a controlled exception to this rule by opening specific port...
