ABC Integrity checks each WordPress core file against the official checksums published by WordPress.org. Any file that has been modified, is missing, or cannot be read is flagged immediately in the dashboard — so you can catch tampering, accidental edits, or signs of a compromised site before they become a bigger problem.
Features
<ul>
<li>One-click scan — no configuration required</li>
<li>Detects modified, missing, and unreadable core files</li>
<li>Automatically re-fetches checksums when WordPress is updated</li>
<li>Lightweight: scans run on demand, not in the background</li>
<li>Plugin and theme files are not checked (core files only)</li>
</ul>
<h3>External Services</h3>
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.

WP Fingerprint works by collecting checksums of your plugins and comparing it with the checksums collected by WP Fingerprint. If the plugin detects any abnormalities it will let you know so you can take immediate action. 
This plugin transmits and stores checksums on WP Fingerprint servers(all hosted in EU and run by 34SP.com) & WordPress.org to work for details see https://wpfingerprint.com/how-it-works/ for the data we collect and store.
