This says to fit for vB 3.8, even if it says 3.6! Many have tried it and it fits on vB 3.8.7 so far perfectly!

I will try it myself too! Good luck

That MOD is for stop bots from Signing up! It has nothing to do with Logging in.
Read the first post again mate.

some use a lot of proxies to bruteforce my forum's member password, any one have idea?

Try this

i am not sure it have Image verification(captcha) on Login

How about https://vborg.vbsupport.ru/showthread.php?t=132482 even if it does say stop bot sign up it still applies to the humans!

Besides, if it is humans trying to get through what makes you think they can't see the images?

i have checkabove two ，they don‘t have Image verification(captcha) on Login。

no one can help？

Why wouldn't this one work for you https://vborg.vbsupport.ru/showthread.php?t=132482 ? as far as i can see there are images involved?

it is only for new user register, not for member login, have you installed it?
so i still need a help .

It makes NO sense to want captcha when dealing with HUMANS. Do you get that? HUMANS CAN SEE THE IMAGES. It will do you NO good. They will simply pass the captcha and continue the brute force attack, if it is HUMANS doing it.

What you need to do is ban their user agent. Here's the mod for that:

Ban Spiders by User Agent

This isn't just for spiders, it's for everything, and I suspect the attacker you have will have something special in his user agent that you can exclude and it won't matter what the IP is.

I feel bad for the OP.

"What about captcha on signup?"
-"How about captcha on login?"
"What about captcha on signup?"
-"How about captcha on login?"
"What about captcha on signup?"
-"How about captcha on login?"

Anyway, I'm pretty sure you can set user agents in Xrumer, which is used for attacking forums.

Except, I didn't give him that. I gave him the actual solution.

they bruteforce with tools, not by human,
i think Max Taxable have not know what i mean,
they can use 100 proxies, then bruteforce password, if we have imagine verification, most tools can not work

Proxies don't matter if you find something in their user agent you can exclude.

Seriously.

Know how to determine their user agent? The tool they're using will likely be part of it, there will be other unique items in it you can exclude.

You have your heart set on a captcha where none exists in vBulletin, unaware that alot of these botnet programs actually defeat captchas. Image verification isn't a magic bullet.

Find out a common item in the user agent of this attacker, and exclude it using the Mod I linked you to, end of problem.

You act like other people haven't seen this before.
