Key Features of WP Fingerprint
- Automated SHA-1 Checksum Generation: The plugin scans every file inside each plugin folder and creates a SHA-1 checksum for it, then sends this data to remote servers for validation.
- Remote Checksum Comparison: Collected checksums are compared against a database on WP Fingerprint servers to detect if any plugin file has been altered without authorization.
- Plugin Version Tracking: Alongside checksums, the plugin captures basic plugin information like version numbers to ensure the checksum matches the correct release.
- Core File Monitoring: When WordPress core files change, the scanner verifies them to catch exploits that target the core system directly.
- Premium Plugin Support: For commercial plugins not in the WordPress.org repository, WP Fingerprint relies on a crowdsourced network to provide correct checksums for verification.
- Admin Menu Indicator: After installation, a dedicated "WP Fingerprint" heading appears in the top admin menu bar, confirming the plugin is active and running scans.
- EU-Based Data Storage: All checksum data is stored on servers operated by 34SP.com within the European Union, addressing some data residency concerns.
