Pentest

Hack.me - Vulnerable web app community

Hack.me is a free community project where people can build, share & host vulnerable web apps to learn and experiment. Each app is sandboxed for you so you are somewhat safe (as safe as you can be on a site with people uploading strange things for security people to break anyway). You can also upload private images for self use. It looks liek a handy tool for anyone interested in learning more about security and penetration testing.
