Descripción

WP Fail2Ban Redux records various WordPress events to your server’s system log for integration with Fail2Ban.

This plugin is (mostly) a drop-in replacement for WP fail2ban by Charles Lecklider.

While WP fail2ban is a great plugin, there are a number of improvements that could be made. In order to facilitate these improvements, a major refactoring of the codebase was necessary.

The core functionality between WP Fail2Ban Redux and WP fail2ban remains the same. WP Fail2Ban Redux is considered to be mostly a drop-in replacement, because all constants have been replaced with filters, and will, possibly, require some upgrade work. Don’t work it’s as simple as implementing the constants.

The following events are recorded by default:

Failed XML-RPC authentication attempts.
Successful authentication attempts.
Failed authentication attempts — differentiated by a user’s existence.
Pingback errors.

The following events can be enabled via filter:

Pingback requests.
Blocked user enumeration attempts.
Authentication attempts for blocked usernames.
Spammed comments.

Extra documentation is available on the WP Fail2Ban Redux GitHub Wiki.

Instalación

Upload the plugin to your plugins directory.
Activate the plugin through the ‘Plugins’ menu in WordPress.
Copy the config/filters/wordpress-hard.conf and config/filters/wordpress-soft.conf files to your Fail2Ban filters directory (generally /etc/fail2ban/filters.d).
Copy the config/jail/wordpress.conf file to your Fail2Ban jail directory (generally /etc/fail2ban/jail.d), or append it’s contents to your jail.local file. Make sure you read the notes in this file to aid successful setup.
Reload or restart Fail2Ban.

FAQ

How do I upgrade from WP fail2ban?

If you haven’t set any of the WP fail2ban constants, you don’t need to do anything. If you have set some of the constants, view the upgrade instructions.

Will the `wordpress-hard.conf` and `wordpress-soft.conf` filters still work?

Yes! All of the improvements made in WP Fail2Ban Redux were done in a way that would allow existing functionality to work without changes to your filters. However, the demo filters included with the plugin do contain some recommended changes. There are also new features not found in WP fail2ban that will require changes to your filters to be effective. These changes are linked, by filter, below:
wordpress-hard.conf
wordpress-soft.conf

Be ye forewarned: Future changes to WP fail2ban may break backwards compatibility with WP Fail2Ban Redux filters. No attempts will be made to fix this. So, even though it’s not required, it is probably a good idea to update the filters anyway.

Can I use this as a must-use plugin in the `mu-plugins` folder?

As of version 0.5.0, yes! Download the plugin, and unzip. Inside the plugin folder will be another folder named wp-fail2ban-redux and wp-fail2ban-redux.php. Upload this folder and file to the mu-plugins directory of your site.

How do you I use this plugin if my site is behind a proxy, like Cloudflare?

You need to add some code to your wp-config.php file. See the below links for guidance.

I use this plugin on my wordpress installations and all failed logins are reliably logged to the auth.log of the server. Even though the plugin has not yet been tested with WordPress 5.4.1, it is working good for me.

Tiny, Simple and Effective. Works Well.Thanks to developer.

I tried some other F2B plugins, tons of useless options, useless interface and so on. And very expensive paid subscriptions, of course. This one just logs all the auth. failures you need to monitor and gives you the F2B filter and jail conf. Install, copy, adapt, reload f2b. 5 minutes and you're done. Be sure to add this plugin as a "mu-plugin" (must-use), so no stupid WP admin user disables it by mistake.

0.5.1

Release date: 2019-09-05
This release requires and update to the wordpress-hard.conf file, in order to fix an issue with matches failing for XML-RPC multicall authentication failures. See https://github.com/thebrandonallen/wp-fail2ban-redux/pull/13/commits/2e3a3867749be7839edfae5707b62921c36ecd85
Fix issue where XML-RPC multicall authentication failures weren’t correctly matched by Fail2Ban with the wordpress-hard.conf filter.

0.5.0

Release date: 2018-10-27
Add better support for use as a must-use plugin in the mu-plugins directory.

0.4.0

Release date: 2018-01-15
Bumped the minimum required WordPress version to 4.5.
Bumped the minimum required PHP version to 5.3. This is a soft bump, meaning, nothing changed that will break PHP 5.2 compatability. However, this could easily change in the future, and PHP 5.2 is no longer actively tested.
Renamed the wp_fail2ban_redux_openlog_indent filter to wp_fail2ban_redux_openlog_ident, because… it was misspelled.

0.3.1

Release date: 2017-05-18
Bump minimum required WordPress version to 4.4.
Performance improvements when not blocking user enumeration.
Use wp_die to exit, to allow for greater customization of exit messages.
Exit messages are now escaped using esc_html.
Refactored plugin loading.
You can now create your own, custom, logging class, in case you don’t want to use the standard syslog() output.

0.3.0

Superseded by 0.3.1

0.2.1

Release date: 2017-02-15
Fix a stupid syntax error in the comment spam filter 🙁 Thanks to @ichtarzan for reporting!

0.2.0

Release date: 2016-09-27
Fixed PHP notices where WP_Fail2Ban_Redux::comment_spam expects two parameters. Decided it was probably a good idea to oblige.
User enumeration blocking now checks for both the author and author_name parameters. The author_name parameter could be used to validate the existence of a particular username, so blocking on this parameter as well will further reduce the attack surface.
Fixes an issue where user enumeration blocking was overzealous and would prevent actions in the admin area. Props pjv. #2
WP_Fail2Ban_Redux::redirect_canonical is now deprecated. If you were doing anything with this function, or the hook that initialized it, you should look at WP_Fail2Ban_Redux::user_enumeration instead.
Added a note to wordpress.conf about the logpath parameter, and common auth log locations. There is no need to changed existing configurations. This is merely to aid setup for future users.

0.1.1

Release date: 2016-07-23
In PHP < 7.0, exit isn’t allowed as a method name. WP_Fail2Ban_Redux_Log::exit is now WP_Fail2Ban_Redux_Log::_exit.

0.1.0

Release date: 2016-07-13
Initial release.
