I have a phpBB 3.0.5 installed on a linux server: (oovium.com/forums/). I noticed two days ago someone using an autogenerated email address from China created a new account without having read a single message. The email address they used was listed on http://stopforumspam.com. I deleted the account.
Yesterday, the same (or similar) email address created another account, but this time they posted a message complaining about having trouble with registration and posted their registration link.
I stupidly clicked the link and it took me back to my forum. I then deleted the account and its message.
The message is deleted so I don't know exactly what the URL that I clicked was.
So my questions: 1. Is there a way to hack a phpBB 3.0.5 by having an admin user click a link? 2. Is there a way to determine if the message board has been hacked? 3. Is there any way to retrieve that deleted message so I can determine precisely what the URL was?
