PicoCTF: “where are the robots” [CTF Write Up]

Have you ever thought about joining the forces of white hat hackers and penetration testers? Don’t you know where to start or how to practice some skills? Though capture the flag games, or CTFs in short, are not the most life-like situations, they can help you to build a way of thinking and to learn the basic tools. PicoCTF is a great site to start as a beginner.

Installing and Automating Let’s Encrypt Certificates with Certbot

In today’s connected world, ensuring the security of web communications is very important. Encrypting data exchanged between users and websites is a mandatory step in protecting sensitive information and privacy. Let’s Encrypt, a free, automated, and open certificate authority, coupled with Certbot, a robust tool for automatically managing SSL/TLS certificates, provides a powerful solution for making the web a safer place. In this post, we will explore the process of implementing Let’s Encrypt and Certbot on Debian Linux to enhance web security.

How To Configure An Apache SSL Reverse Proxy on Linux?

What is Apache?

Apache is a free and open-source cross-platform web server software that allows users to deploy their websites on the internet. It was launched in 1995 and has been the most popular web server on the Internet since April 1996.

What is a reverse proxy?

reverse proxy is a server that sits in front of web servers and forwards client requests to those web servers. It acts as an intermediary, intercepting and inspecting incoming client requests before forwarding them to the web server. Reverse proxies can provide additional levels of abstraction, control, security, and performance optimization. They are commonly used for load balancing, web acceleration, and to hide implementation details about the web servers.

What is SSL?

SSL, or Secure Sockets Layer, is a protocol for establishing authenticated and encrypted links between networked computers. Its current iteration is called TLS (Transport Layer Security).

Fortifying Our Application: Preparing Against the OWASP Top 10

The OWASP Top 10 is a widely recognized list of the most critical security risks for web applications. It is updated every few years based on data analysis and community feedback. The latest version, released in 2021, introduces some new categories and changes some existing ones to reflect the current threat landscape.

As developers, we should be aware of these risks and take steps to prevent them in our applications. In this blog post, we will briefly review each of the OWASP Top 10 categories and provide some best practices and resources to help us secure our code.

Automating web services using Ansible

Web services are applications that run on the internet and provide functionality to other applications or users. They can be complex and require a lot of configuration and maintenance. Ansible is a tool that helps us automate the deployment and management of web services. It allows us to write simple and declarative scripts that describe the desired state of our web services, and then execute them on multiple servers. Ansible also handles the dependencies, errors, and changes that may occur during the automation process. By using Ansible, we can save time, reduce errors, and ensure consistency and reliability of our web services.

How to brute force a web application password with Burp Suite? Basic dictionary attack in practice!

With Burp Suite we can initiate dictionary attacks against a website. This time in this simulated attack we will brute force the login field of the Juice Shop web application. We already know the email address of an admin user, so we have to make sure to find the right password.

Important note: hacking in the wild is illegal! Do NOT do it out of the lab, unless you are a penetration tester with a signed contract!
