RastaLabs is a virtual red team simulation environment, designed to be attacked as a means of learning and honing your engagement skills. The focus of the lab is operating within a Windows Active Directory environment where players must gain a foothold, elevate their privilege, be persistent and move laterally to reach the goal of Domain Admin. The lab features a combination of attacking misconfigurations and simulated users. Prior experience is not strictly required to beat the lab, but it will be a steep learning curve!

Offshore is an Active Directory lab which simulates the look and feel of a real-world corporate network. Users start from an external perspective and have to penetrate the “DMZ” and then move laterally through the CORP.LOCAL, DEV, ADMIN and CLIENT forests to complete the lab. It was designed to appeal to a wide variety of users, everyone from junior-level penetration testers to seasoned testers as well as infosec hobbyists. Players will pick up at least a few new tricks which can be immediately applied to real-world engagements.
