Dear Andreas, thanx a lot for this. one question: When i use your .htaccess settings, i can´t access my media anymore. THe media library is shown as empty. Do you have an idea how to solve this?

Best regards,
Robert

I've the same problem...

I too am facing the same problem and upon the trials I found that the 7G code is the problem. Once I disabled/removed everything started working fine.
The error that I was getting were:

• The resource from "http://.../wp-content/plugins/autoptimize/clas…ternal/php/persist-admin-notices-dismissal/dismiss-notice.js" was blocked due to MIME type ("text/html") mismatch (X-Content-Type-Options: nosniff).
  admin.php
• The resource from "http://.../wp-admin/load-scripts.php?c=0&load%…media-audiovideo,mce-view,imgareaselect,image-edit&ver=5.2.2" was blocked due to MIME type ("text/html") mismatch (X-Content-Type-Options: nosniff).
• The resource from "http://.../wp-content/plugins/autoptimize/clas…ternal/php/persist-admin-notices-dismissal/dismiss-notice.js" was blocked due to MIME type ("text/html") mismatch (X-Content-Type-Options: nosniff).

Browser - Firefox 68 also tested the same on Chrome

Hi!

Change 7G-Firewall back to 6G. https://gist.github.com/HechtMediaArts/f2ffa095a4bfc5969746ac622c8a06c0

@HechtMediaArts Moin/ Tach auch Andreas. Fabulous!

Security Ninja for WordPress also suggests to deactivate wp-admin/upgrade.php. Is there any reason against

# No access to the upgrade.php
<files upgrade.php>
Order allow,deny
Deny from all
</files>

?

.. and what about denying directory listings as per https://stackoverflow.com/questions/5932641/deny-directory-listing-with-htaccess?

# Deny directory listings (several approaches)
Options -Indexes
IndexIgnore *
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>

# END Deny directory listings

Hello, a slight gain by removing:

thanks for pointing that out. The line in Andreas Hecht (aka HechtMediaArts)'s above .htaccess to search for and remove is without spaces around the /:

I have remarked that

Disable Code Execution for Uploads directory : Enabling this option will place a .htaccess file in your wp-content/uploads/ directory which prevents any PHP code in your uploads directory from executing. This is an added level of protection against a hacker managing to upload PHP code into your uploads directory. Even if they manage to do that, the code won’t execute if you have this option enabled. The contents of the .htaccess is:

# Code execution protection

<IfModule mod_php5.c>
php_flag engine 0
</IfModule>

<IfModule mod_php7.c>
php_flag engine 0
</IfModule>

AddHandler cgi-script .php .phtml .php3 .pl .py .jsp .asp .htm .shtml .sh .cgi

Thank you @pascalduboin . My wp-content/uploads/.htaccess already contains the following code:

  <IfModule !mod_authz_core.c>
    Order allow,deny
    Deny from all
  </IfModule>
  <IfModule mod_authz_core.c>
    Require all denied

Do you see anything in it that conflicts with your code snippet? Would you add yours in addition, or replace mine with yours?

Not Working with Multisite (BuddyPress), showing 404 error
Added Network code at the end, but getting 404 for all pages

RewriteEngine On
RewriteBase /networkname/
RewriteRule ^index.php$ - [L]

add a trailing slash to /wp-admin

RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(..php)$ $2 [L]
RewriteRule . index.php [L]

Is this going to work with WP rocket or do I have to kill all the caching parameters before that?

Hello,
Is the code above also works for multisite wordpress?

Thanks for these code. Is there a way to also hide /wp-content/ and wp-content/* from the url? if so, would that block the images from showing under under /wp-content/uploads/?

and what will it show instead?

better not to do it, wp-content is not only uploads but plugins and etc
Options -Indexes is fair enough to close the indexing of all directories

Technically I don't want to show any wp_* at all. My goal is to prevent visitors from knowing this is a WordPress site, at least in first glance. What is the best path to achieving this?

You can protect your Wordpress with Security plugins like All In One WP Security (it has a lot of features that add extra htaccess rules, hide access to system files, protect your wp-admin and etc) , but you can't hide the fact that it's WP entirely, your site won't work if you close access to wp_ directories, because WP itself work with it.

@HechtMediaArts Moin/ Tach auch Andreas. Fabulous!

Security Ninja for WordPress also suggests to deactivate wp-admin/upgrade.php. Is there any reason against

# No access to the upgrade.php
<files upgrade.php>

yes, there is: after a WP update:

Forbidden You don't have permission to access this resource

a lot of problems you have there... wordpress 5.5.1, nginx dynamic can't work with that. your htacssas cause me a lot of problems.
recommended you to adjust the file.

@seoagentur-hamburg
thank you
with the updates :) the security Headers is boom, but need little adjustment for Nginx.
Thank you for any time for updating the file for the people, you are a good person :)

Is double line 178-182 and 197-201 mistake or?

@robi052 I think you are right. It can be summarised.

@seoagentur-hamburg Can you please summarise it?

Version 1.5 of the 7G Firewall (https://perishablepress.com/downloads/7G-Changelog.txt) is already available. @seoagentur-hamburg can you please integrate it?

Is something wrong only with my website? 🍡

hi there! many thanks for this very useful file!

i would recommend adding support for javascript modules (.mjs files) by adding /changing:

...
AddOutputFilterByType DEFLATE text/javascript
...
<FilesMatch "\.(ico|pdf|flv|swf|js|mjs|css|gif|png|jpg|jpeg|txt|woff2|woff)$">
...
<FilesMatch "\.(js|mjs|css|xml|gz)$">
...
<FilesMatch ".(js|mjs|css|xml|gz|html|woff|woff2|ttf)$">
...
