Skt NURCaptcha Plugin for WordPress

Featured

NURCaptcha stands for New User Register CaptchaSkt NURCaptcha WP Plugin was conceived as a simple solution to a problem I faced with some time ago.

I had decided to change preferences in a WordPress powered site so to allow people to freely register as new subscribers. But as soon as this was done, a lot of bot intruders came in and in a blink the site’s pages were infected by some russian (.ru) malware. Then I digged around for some plugin to give me some security on that wide open gate of my site.

That is how the reCaptcha shows up at your Register Page

As I have not found any plugin fit to solve that simple problem, I decided to build one by myself. That is how Skt NURCaptcha WP Plugin came to being.

Skt NURCaptcha WP Plugin is called to action by the “login_form_register” hook. Then a call is made to a Google’s reCaptcha form which is inserted into the WP native register form. To know more about reCaptcha Safety, go here. If someone wants to register to that site correct responses to the Captcha challenge must be filled in.

It’s a simple idea and a good solution to stop bots attacks. And it’s free also! All you need is to have the plugin properly installed and activated in your WP site, and then you go to Create a reCaptcha Key to create a pair of free criptographic keys to enable the plugin.

Simple, Safe and efficient!

 

New improvements from Version 3

Skt NURCaptcha Plugin now brings your WordPress site to a new level of security.

From version 3 on, we added antispam databases assessment, so even if the spammer gets the spambot gone through Google’s reCAPTCHA challenge, the IP and email will be checked against StopForumSpam and BotScout spammer databases.

This additional checking became a real need since some spammers found some way to cross the captcha barrier, a few months ago. They are probably using a cross-site game, by making someone else unadvertedly solve the captcha challenge for them.

Version 3.1 also changed storage of blocked attemptives from text file mode to database mode, so there will be no more data loss at the plugin update.

Version 2.4 Released

Though it was first released on september 21st, Skt NURCaptcha Plugin for WordPress has now reached it’s version 2.4 which gives you support for user registration in WPMU (Multisites) and in BuddyPress.
WordPress for Network, aka Multisites, introduces some changes in the registration process which allow user to create a new blog on the network. The registration functions are declared at . BuddyPress is a special kind of plugin, as it introduces many changes to the internal structure of WordPress. BP registration routines are present at and they differ a lot from those of the regular WP installation.
It’s hard for a plugin to do a good job when so many changes cross his way. In fact, when we compare those routines, we see a jungle of non-standardized changes. The hooks are not the same and even field names on the registration form are different. See, as an example, the “username” field. In standalone WordPress this field is called “user_login”, but if you reconfigure your installation to allow Multisites, this field’s name becomes “user_name”. If you install BuddyPress plugin, however, this same field changes it’s name to “signup_username”.
Nevertheless, when we have a clear goal in sight and a lot of enthusiasm in heart, no bad times come across our road to a brand new version of Skt NURCaptcha. So, enjoy it as we keep one eye on further improvements.
Commentaries and suggestions are very welcome to help improving this plugin, as it is meant to protect your site the best way possible, at that “user registration” door.
