I had some fun this weekend messing around with Ghidra. Having such a powerful tool for free is truly a game changer. To start scripting in Ghidra, I downloaded the latest Eclipse for Java Developers Version: 2019-09 R (4.13.0), Ghidra and Open JDK, I believe any JDK version 11+ will work. After downloading the JDK, extract the zip, put it somewhere and modify your PATH and JAVA_HOME environment variables to point to it:...

Hello and welcome to Nucu Labs agent! We’ve been contracted by some external contractors to help them break…, I mean, assist them in making their life easier with their “competition”.

I started reading this book in november and it took me about two weeks to finish it. You should be a bit comfortable Linux and programming if you plan to give it a try. Here are my thoughts about it. What I like the most about this book is that it explains the subject in a straightforward and concise way! The author is a very knowledgeable security researcher and his work is state of the art!...

This is my first book review that I did my blog, I’m not really good at reviewing books and I’m not a native english speaker either, so bear with me and my clumsy english. I must also say that the subject covered by the book overwhelms me, I don’t claim to be an expert on the topic and and to be honest I don’t really want to become one, reading this book has provided me with enough information in order to be able to hold a basic discussion about cryptography related topics, had I put more effort, time and thought in this book I could probably become proficient....

PicoCTF is an amazing capture the flag competition targeting middle and high school students. It’s a game that consists in solving various computer security challenges from different domains, see the picture below. 🙂 While I’m just starting out to explore the field of computer security I feel that I’ve learned a lot doing these challenges, there are many other challenge sites on the internet but their difficulty is for experienced users, beginners like me often struggle as there are no hints and you don’t know how to tackle the problem....

After we setup the server, we will setup an obfuscation server in order to disguise our traffic indicating that we’re using a VPN. This will help us evade some form of censorship. Why use a VPN? First, let’s talk about why you may want to use a VPN server:...
