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.
Detect Administrator Accounts Added Behind Your Back
Keeps a list of approved administrator accounts and checks it daily and on every dashboard visit; administrators that appear any other way (for example inserted directly into the database by malware) trigger an email and a warning with an approve button.
Lock the Site URL and Admin Email
Ignores changes to the WordPress Address, Site Address and administration email made from the dashboard, a common target after an account takeover.
Security Headers for wp-admin and the Login Page
Sends nosniff, a strict referrer policy, a restrictive permissions policy and a cross-origin opener policy on dashboard and login pages, which front-end header snippets do not cover.
Warn When There Are Too Many Administrators
Shows a dashboard notice listing the administrator accounts when there are more than you expect, a prompt to downgrade old or unused ones.
