Assembly is a low-level programming language. You already know that low-level programming languages are close to machines and very hard to understand by humans. We have already written some programs....
A web shell is a type of code that hackers use to gain control over a web server. It is particularly useful for post-exploitation attacks, and there are various types of web shells available. Some....
Metasploit is an awesome tool which is. It can automate the exploitation process, generate shellcodes, use it as a listener, etc. I hope to start a tutorial series on the Metasploit framework and....
Edge computing is a distributed computing paradigm where computation and data storage are performed closer to the location where it is needed. Instead of relying solely on a centralized data center,....
Hi all, It's a new article on something cool. Here we are going to see how we can use the Hubspot schema connector with Ballerina. When it comes to building connectors for seamless integration....
In this blog, I’ll walk you through how I built a Tic-Tac-Toe game using an AVR microcontroller, a 4x3 keypad, and a grid of LEDs. This project combines the basics of embedded programming, game....
In a normal Windows/Linux environment, you have heard about moving data or files. What we do is copy data from a source location to a destination. The assembly MOV instruction is very similar to....
Today, I selected an interesting topic to discuss. Here, we are going to disassemble a binary file and take a look at what it does. This process is called reverse engineering. Let's run the program....
The Stack in Computer Science The stack is an important concept in computer science. If you are planning to learn reverse engineering, malware analyzing, exploitation, etc., this concept is a must to....
Understanding Remote Command Execution (RCE) Vulnerabilities Remote Command Execution (RCE) is a critical security vulnerability that allows an attacker to execute arbitrary commands on a remote....
In today’s post, we’ll walk through solving a basic crackme challenge using GDB. You can also solve this challenge on a Windows platform using IDA. I found a crackme collection on GitHub, and....
GDB is shipped with the GNU toolset. It is a debugging tool used in Linux environments. The term GDB stands for GNU Debugger. In our previous protostar stack0 walkthrough tutorial, we used GDB many....
Hi 👋, I'm Thilan Dissanayaka. An Engineer from Sri Lanka. I studied at University of Ruhuna and currently working at WSO2. Here I write some cool stuff about Computer Science-related topics.
