Best open-source Red Team tools

One of the best features of the cybersecurity community is the vast number of free and open-source tools that are available. Many very smart and skilled hackers have developed tools for a variety of purposes and made them available to the community.

In this article, we’ll discuss some of the best open-source tools for Red Teaming, organized by the role in the cyberattack life cycle.

It allows the Red Team to identify different domain names within the target network and the associated IP addresses, which can be useful for targeting different types of attacks. It also has additional DNS-related functionality like testing for zone transfers.
