This sort of thing has been happening all the time on many sites and forum, so it was inevitable that it will happen here eventually. New Bots are being written to seek out lits of embers and then using brute force attacks to find weak passwords. This is why you always need to change your passwords.

I implemented a very simple, yet effective ways to fight these Bots. There are on the other hand a real person attack 'Hacker' which can visit your site. With some ISP providing proxy IPs and redirects, blocking IP number will be a total waste of time.

I can tell you that most of the attacks are coming out of Asia, Poland, Turkey, Federation, Germany, Ukrane, UK and yes USA. So if you block these IPs you also block possible effective members.

I too received the same notifications of attacks to my account, and when I read the IPs I just laughed. You see these all the time on my other sites, and they will tire and soon return as always. Scan you user database for weak passwords, notify the user to regularly change them. Most importantly, implement a simple and effect means to filter those Bots.

Sorry for this lengthy reply, but we do tend to panic over very simple and rectifiable problems.
