Core file integrity
The File Integrity Monitor now has a Core integrity page (Scan now + a results table) and detects unknown / injected .php files inside wp-admin and wp-includes — a common hiding place for backdoors — in addition to modified and missing core files. It checks your core against the official WordPress.org checksums and pairs with the File Scanner (which covers wp-content) for a complete malware sweep.
