Well, this was quite a tricky challenge, for me at least. I did manage to get one of the 5 machines, which was quite an easy linux stack bof for an app called vuln which they provided the source code for. I guarantee everyone on the scoreboard got that one!

Congrats to the winners!

In the course of the 48 hours 4 of the 5 machines were compromised, with the exception of the deadcow, which I spent way too long poking.



Really looking forward to seeing any write-ups!
