A detailed why or how is not going to be possible with the limited information you’ve provided. For a detailed forensic investigation we would need more than just an IP and arbitrary Username, in fact we would need everything… DB, access logs, changelogs, codebase – quite literally everything you’ve got and even then it’s not … Read more
On a multisite install, go to the Network Admin area and add the webm file extension to the allowed extensions list. On a single-site install, add this to your wp-config.php file: define(‘ALLOW_UNFILTERED_UPLOADS’,true); That will allow administrator level users to upload files without the file type restrictions. The underlying problem is that webm hasn’t been added … Read more
You could try hooking into template_include and showing the user a completely different page containing the login form (without changing the URL) if the post is password protected.

With the user-name-based nonces, i think you are trying to protect yourself from CSRF attacks, this should work to some extent (hard to tell without the full source code), that being said the nonces should be assigned to a specific action (not only an action), so, for example, you do not assign it to a … Read more
As mentioned, updates are vitally important, as are good password practices. I manage many WP sites, and I check (and install) updates every day. I also have some security things that I do by default to reduce the ‘footprint’. Among them are to not have a user called ‘admin’, disable xmlrpc, strong passwrods everywhere (host, … Read more
but I would like to hide all the other information as much as possible since I feel like the more information those hackers know, the less security my site is. 99.999999% of attacks you get will be fully automated bots.
