Add a Random Suffix to Uploaded File Names
Appends a short random string to the name of every uploaded file (for example report-k3f9q2.pdf), so private documents cannot be found by guessing their URL.

Security snippets for WordPress
Snippets that harden WordPress: turn off XML-RPC, hide the version number, stop user enumeration, add security headers and block risky uploads. Small, reviewable changes for site owners who want fewer attack points without a heavy security plugin.
Alert When PHP Files Appear in the Uploads Folder
Scans the uploads folder once a day for PHP files, which never belong there and usually mean a backdoor, and emails the administrator and shows a dashboard warning when new ones show up.
Allow Only Safe File Types to Be Uploaded
Limits uploads to common images, documents, audio and video, and rejects files with a hidden second extension such as photo.php.jpg.
Block PHP Execution in the Uploads Folder (Apache)
Adds Tools > Uploads Protection with a button that writes .htaccess rules to your uploads folder so PHP files there can never be run, even if one slips through an upload.
Limit How Many Files Non-Administrators Can Upload per Hour
Caps uploads at 30 files per hour for each user who is not an administrator, which limits the damage a compromised author account or a buggy front-end upload form can do.
Reject Uploads That Contain PHP Code
Scans every uploaded file that is not a PHP file for hidden PHP code (such as an image with a PHP payload) and refuses the upload if any is found.
