We have setup free online access to the entire OWASP Collection for everyone to participate in and hone their skills more against pre-vulnerable webapp environments.
You may come on discord to also access all the links and information, plus communicate with the mods and the community.
If an environment breaks or needs a reset, please contact a mod on discord or irc to have the system fixed which takes only a couple minutes to restore snapshots of each challenge.
Each accessible environment will be listed as a comment on this link for now, you may use the website or discord to find the same information. Happy Hacking!
