hi
I'm new here:-)
actually I'm not a hacker but suffering from them. I have a site which is vBulletin Version 3.8.2. My site was hacked 2 times by a hacker. He is very nice man he just replace the index file only without any damage of other files and folders. He just put a massage tell " I like your forum too much, so I hacked it"
My questions are:
How he did this?
Can I learn something to avoid hackers?
Thank you
