As some of you may have noticed, we appear to have been suffering forum issues throughout today. Many users I have spoken to have been confronted by a "you have exceeded the maximum number of login attempts" message upon trying to login, despite they not having attempted multiple times.

After investigating, I suspect that what's happened is that we've been the recipient of an attempted brute force attack by a bot - trying to get into those accounts that it can find via whatever means by way of guessing passwords. We currently have the maximum number of login attempts set to 3 for the board before CAPTCHA display is triggered, however CAPTCHA on login was seemingly broken up until a few minutes ago when I fixed it. As a result, some of you may have been unable to login today - my apologies about that.

As a result of the assumed attack, I've setup the board so that an entry is written into a log when the "you have exceeded the maximum number of login attempts" triggers for users. This will allow me to keep an eye on the IP addresses and accounts triggering the message and hopefully, should another attack occur, allow me to identify and IP ban any bots attempting the same thing in future.

That said though, I urge everyone to ensure that they are using a secure password for their account - something that a brute force attacker will not be able to easily figure out. This is especially true if you're one of the ones affected by this issue today - it would not do to give any attacker an easy ride should they return and try to access the same accounts again!

How long should the maximum login attempts message appear btw Anny? What I mean is, if I (and others) received the same message again today after we'd received it yesterday but then logged in okay once the captcha was displaying, does that mean a bot has tried to gain entry again since? Or is it just that the message will stay around a while?
If that makes any sense lol. :)

Yes, that's what it means. I tested myself earlier whilst at work too and had the issue again. If you login, confirming yourself with the CAPTCHA, it should clear any 'rogue' attempts (meaning that if yuo log back out straight away, and try to log in again, you won't get the CAPTCHA), and did so for me upon testing - so it basically means that the bot has been back since, yes.

I've already identified a couple of IPs I'm keeping an eye on, as they are coming up as recieving the CAPTCHA login for multiple accounts. If the pattern continues over the weekend, I'll probably take action on Monday. Hopefully that will solve it.

Do the IPs you're seeing problems from originate from a specific region/country?

Germany, somewhat surprisingly.

Good good :thumb:


Don't think blocking the whole of Germany is very viable tbh Mech :lol: :)

You do have the ability to create exception IPs in the list. :p

Thanks for the link, but we definately won't be going down that route. We have German members, and I would not want to deny anyone access to the site based solely upon where they live. Even if we made use of the exception list, it would effectively deter any new members we may garner from Germany - since they'd have to give us their IP before they could access the forum.

I'll try and control it through individual IP bans more than likely based upon data I gather in the log. If that does not work and I can't find any other feasible solution, it's simply the case that we'll have to live with the CAPTCHA showing up on login - after all, that's not ideal but it's not an overly huge price to pay!

San Francisco too by the looks of it, though mainly Germany.

Just happened to me as well, so they're at it again today. Has the script you installed been of any use in confirming the source of these attacks?

I missed this whilst I was in the process of rebuilding my machine. When I have finished reconstructing it from the software side of things this weekend I will take a look back through the logs and update regarding whether I can identify a pattern and/or have taken action against an IP.

Sorry about the delay.

I just got that 'exceeded login attempts' message just a few minutes ago despite not logging in for like, four months or so. Hope this info helps. End of line.

That's more than likely an old trigger, saved up from one of the incidents a few months ago. I'll go through the logs though and take a look just incase, thanks for pointing it out Fen :)
