About ABC Integrity
From the official readme · v1.0.3Description
ABC Integrity checks each WordPress core file against the official checksums published by WordPress.org. After a scan, any file that has been modified, is missing, or cannot be read is flagged in the dashboard — so you can catch tampering, accidental edits, or signs of a compromised site before they become a bigger problem.
Features
- One-click scan — no configuration required
- Detects modified, missing, and unreadable core files
- Automatically re-fetches checksums when WordPress is updated
- Lightweight: scans run on demand, not in the background
- Plugin and theme files are not checked (core files only)
External Services
ABC Integrity connects to the WordPress.org Core Checksums API when an administrator runs a core file scan. The request sends the site’s WordPress version and locale so WordPress.org can return the matching official checksum manifest.
Service: https://api.wordpress.org/core/checksums/1.0/
Terms: https://wordpress.org/about/terms/

Installation
- Install and activate the plugin through the WordPress Plugins screen.
- Navigate to ABC Integrity in the admin menu and click Scan core files.
Frequently asked questions
Does this plugin check plugin or theme files?
No. ABC Integrity only checks WordPress core files. Plugin and theme files are not scanned.
What does it mean if a file is flagged as modified?
It means the file on your server doesn’t match the official WordPress checksum for that file. This could be intentional (a manual edit), accidental, or a sign that your site has been compromised. You should investigate any flagged file and restore it from an official WordPress release if you didn’t make the change yourself.
Does running a scan slow down my site?
No. Scans run only when you click the button in the dashboard — there is no background processing, scheduled scanning, or impact on front-end page load.
How does the plugin get the checksums?
When you run a scan, the plugin fetches the official checksum manifest from the WordPress.org Core Checksums API (api.wordpress.org), matching your exact WordPress version and locale. The manifest is cached and automatically refreshed when WordPress is updated.
