πŸ†•πŸ†•πŸ†• walkthrough! Walkthrough of the machine called “RubyDome” in the OffSec Proving Grounds…don’t watch unless you want help getting through the machine. In this machine we abuse pdfKit utilizing a python exploit to gain a shell and then escalate privileges using an incorrectly set “sudo no password” on a Ruby script. Hope this helps someone and happy hacking πŸ‘Š!
