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.
