OverTheWire CTF Wargames
Summary
The community-based project OverTheWire offers Capture-The-Flag (CTF) wargames for IT-Security enthusiasts and learners. The wargames all focus on different aspects of IT-security or computer sciences like for example Linux systems, cryptography or serverside web application security. The official website OverTheWire.org lists 13 available wargames as of december 2024, with only one of them being available for offline use. The other 12 games are accessed via either SSH or in the case of the serverside web application security focused wargame “Natas” , via a web browser and other tools. As usual for CTF Games in IT-Security, the goal of each level in the wargames is to obtain the password for entering the next one, in this case for accessing the SSH user. The website offers little guidance to beat the challenges posed by the wargames but being around for much over 10 years, a lot of blog entries and YouTube walkthroughs on the wargames have emerged.
Requirements
- Operating system: Any, that can run a SSH Shell.
