Protection from login, register and reset-password brute-force attacks.

Why humans should prove that they are humans by filling captchas? Lets bots prove that they are not bots with adding javascript to their user-agents!

Important: delete username 'admin' if you have it on your site. More than 90% of brute-force attacks try to crack the 'admin' username.

Top 10 most commonly used and worst passwords. Do not use them:

  • 123456
  • password
  • qwerty
  • abc123
  • 111111
  • 123123
  • 000000
  • admin123
  • iloveyou
  • letmein

How does Security-protection plugin work?

The blocking algorithm is based on 2 methods: 'invisible js-captcha' and 'invisible input trap'.
The 'invisible js-captcha' method is based on fact that bots does not have javascript on their user-agents.
The 'invisible input trap' method is based on fact that almost all the bots will fill inputs with name 'email' or 'url'.

How does Security-protection plugin work in details?

Two extra hidden fields are added to login, register and reset-password forms.
First field is the invisible captcha (copy and paste the code). Second field should be empty.
If the user visits site, than first field is answered automatically with javascript, second field left blank and both fields are hidden by javascript and css and invisible for the user.
If the brute-forcer tries to submit the form, he will make a mistake with answer on first field or tries to submit an empty field and brute-force attack will be automatically rejected.

How does Security-protection plugin stop brute-force attacks?

If Security-protection check was not passed than it is brute-force request and the login attempt (or registration, or reset password) is blocked even if username and password are correct.
Plugin sends fake WordPress login cookies to the brute-force bot and redirects it to the admin section to emulate that the password is cracked and many brute-forcers stop their attacks after this.
It is really awesome :)

How to test what brute-force attacks are blocked?

You may enable sending info about blocked brute-force attacks to admin email.
Edit security-protection.php file and find "$secprot_send_brute_force_log_to_admin" and make it "true".

If this plugin does not help you to stop brute-force attacks - you can simply rename wp-login.php file for now and maybe this can help you to reduce load on your site. And also create empty wp-login.php file for not raising WordPress 404 error because it will start whole WordPress site again during each wp-login.php access.
