Have I been hacked? Simple .htaccess question.

Have I been hacked?

I noticed the .htaccess file was changed a few days ago. Downloaded a copy and compared to an older backup I have.

Here’s the old:

# BEGIN WordPress

# END WordPress

Here’s the new:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I did recently change my theme, but that was on the 18th. The last change was on the 29th, the same day a developer had access to it.
