I am curious for peoples opinions on white hat hackers hacking vulnerable hosts and patching and backdooring them. I did some research and found this group who had compromised 1000's of hosts just to secure them. Looking for some feedback - I did a write up on this at one of my sites and opened it up for comments but comments here are just as good. If you want to read and comment there it is the latest post at computersecurity.org -Ryan
