Blue Team - Labs and Study Recommendations

We all know that learning how to be an amazing blue team professional can be a little hard. There are tons of red team labs but if you know where to look they do have good Blue Team labs too! In this topic I want to start gathering different tools and learning opportunities to become a great blue teamer!

For full transparency:

DO NOT SPOIL / DISCUSS ANSWERS FOR LABS

Always run these labs in an isolated virtual machine that has no connection to the internet as a minimum safety precaution.

Basic NDR challenges

At the root of many detection opportunities is network detection and response (NDR). By using Wireshark and PCAPs with samples, you can learn how to investigate malicious behaviour.

Malware Traffic Analysis

The website https://malware-traffic-analysis.net/ is a good starting point to learn and understand threats on the network. Be aware, some samples contain live malware; do take precautions.
