Sometimes you want to access services running on unusual ports, like a SSH server running on port 2222 for example. If connection fails, how can we detect the outgoing ports that are filtered or open on the network?
ReadOur colleagues from the Cyber Command of Belgian Defense organize a Cyber Summer School. This training will give you the opportunity to spend five days with our cyber experts and to improve your cyber skills. And of course, they also have social activities planned to occupy your evenings!
ReadToday a lot of tools and scripts are written in Python (or in Go, let's be honest). If you want to run these on your Windows computer, well you'll have to install Python. But between the different versions, the libraries, and managing the PATH, the task can be quite of a challenge! In this blog post we show how Anaconda can help...

Due to the numerous advantages of machine learning (ML) algorithms, many applications now incorporate them. However, many studies in the field of image classification have shown that MLs can be fooled by a variety of adversarial attacks. This raises many questions in the cybersecurity field, where a growing number of researchers are recently investigating the feasibility of such attacks against machine learning-based security systems, such as intrusion detection systems.
ReadCongratulations to the team Royal Military Hackademy who won the Cyber Security Challenge 2023!
ReadIn a previous blog post, we have explained what SQL injection is, and how to exploit it using sqlmap. In this blog post, we will show some additional techniques: how to exploit web applications that use clean URLs, how to exploit a POSTed form, how to hide traces etc.
ReadThe qualifiers of the Cyber Security Challenge 2023 took place last week-end. Congratulations to the teams from the Royal Military Academy and the Université Libre de Bruxelles who ranked 1st, 4th and 5th, out of almost 300 participating teams!
ReadIn previous blog posts, we have already illustrated two web application vulnerabilities: brute force login cracking and SQL injection. In this post we illustrate a 3rd vulnerability, unrestricted file upload, and show how it can be exploited using a web shell.
ReadIn this blog post, we will show that a login page from a web application can be easily cracked if the application does not implement specific protections against this kind of attack.

Code injection is one of the most critical web application vulnerabilities. Indeed, the consequences of code injection can be dramatic (impact). Moreover, still today a lot of web applications are vulnerable to code injection (frequency). Finally, some tools like SQLMap allow to automatically detect and use these vulnerabilities (exploitation). For this reason, the vulnerability is listed in the top 10 published by the Open Web Application Security Project (OWASP) [1]. In this blog post, we will present one type of code injection, called SQL injection, and we will show how to perform a SQL injection attack with SQLMap.
