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.
Snippet Library
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 wp-config.php, .htaccess or Root Files Change
Checks your site's root folder once a day and emails the administrator when wp-config.php, .htaccess, .user.ini or php.ini change, or when new PHP files appear next to WordPress's own files.
Daily Core File Integrity Check
Compares your WordPress core files with the official checksums once a day and emails the administrator if any file was changed or is missing.
Daily Plugin and Theme File Change Monitor
Fingerprints every PHP file in your plugins and themes once a day and emails the administrator a list of files that were added, changed or removed outside of normal updates.
Protect wp-cron.php From Outside Requests
Requires a secret key for requests to wp-cron.php and adds that key automatically to WordPress's own cron calls, so outsiders cannot hammer the endpoint to slow your site down.
