Brute force will block logins via IP, not username so if you have it configured correctly, you won't have to worry about them ever trying to break your passwords again. It would take too long.

I look at my brute force reports now and then... But mostly I don't worry cause it blocks them.

I'm considering blocking China too. I do get indexed by baidu but I receive relatively little traffic from China. Its strange that its beneficial to cut 1 billion people off.

China's government has to know about these things. They are heavily industrialized and they seem to steal everything they can. Our government is doing nothing about it.

How did you make that trap? That's hella cool.

I just started receiving these emails now. Obviously it's working to keep them from getting into my account. But how do I set up my vbulletin to do the same for my site? Someone mentioned Brut Force?

If you checked "Remember Me?" whenever you last logged in and just close your browser when you're done browsing instead of logging out, then these brute force attacks won't affect you.

They only lock you out from logging in, but if you're already logged in, then you can still use the site as you would any other day.

As for account locks, for the reference, I've got a total of 66 e-mails.

Same here...just now. a few times.

I reset my password.

Damn, this is happening to me now. I came to create a thread but apparently some botnet is having a field day on these forums.

And clearly VB staff doesn't care much about these attempts given no one has officially commented in the past few days?

Amazingly this is not true according to Spamhaus
most spam comes from US

The staff has no control over it.

I like how I was notified by vB that someone attempted to login to my account. How do I set up my site to do the same thing... and track those attempts?

First off, I disagree. They can start banning IP ranges so this doesn't keep happening slowly to their entire userbase.

Secondly, even if they don't take any action to prevent it, it couldn't hurt to send users emails to inform them that apparently botnets are trying to brute force their way into people's accounts, and to take the proper measures (ensure passwords are secured, etc).
