ABC Integrity

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.
