Does anyone know if there is anything like this http://www.cback.de/ for SMF?
like what? Although I can puzzle out german, I don't have the time nor inclination to do so. Please explain more thoroughly what kind of function you are asking about.
A friend of mine got his sites (one phpBB and one SMF) hacked and pretty much wiped the other day. He is still rebuilding them now, but he has added this "cracker tracker" to the phpBB site. Basically i was wondering if there was any extra security we can get for SMF.
I'm still not sure what you are talking about.... What "extra security" does this "cracker tracker" provide?
However, I will say that, as far as I know, all of the supposed, reported, hacks to SMF have been done through other scripts or via the server itself and there are no current security holes in SMF...
If your friend's SMF site was indeed hacked, then have him send his access logs (available in cpanel) to the SMF project team...
I think he has V-Deck but i will ask him.
