Due to my passion for security and machine learning, I’m particularly interested in security weaknesses in machine learning. In the last few years also the interest of the machine learning community in this topic has been increased dramatically and a lot of scientific literature…

Reusable, maintainable and easy to understand machine learning code — Less code usually results in readable code that is easy to understand and easy to maintain. The Python programming language, that has become very popular in the machine learning community, allows you to achieve great results with less code compared to other programming languages. PyTorch is a popular deep learning…

A subdomain takeover is a vulnerability which allows an attacker to serve content from a subdomain which is not owned by that attacker. The most common situations which make a subdomain takeover possible are: 1) the CNAME record of the affected subdomain points to a domain that can be claimed…

MNIST is a widely used dataset of handwritten digits that contains 60,000 handwritten digits for training a machine learning model and 10,000 handwritten digits for testing the model. It was introduced in 1998 and has become a standard benchmark for classification tasks. It is also called the “Hello, World” dataset…

This article briefly describes a critical zero-day vulnerability called Log4Shell that existed in the widely used Java logging library Log4j used by millions of Java applications reachable from the Internet. …
