<h3>Privacy and Data Collection</h3>
VMP Fence respects your privacy and follows WordPress.org guidelines for external service usage. This plugin may collect and transmit data to external services for security analysis:
Google Safe Browsing API: When URL reputation checking is enabled, URLs found in your content, posts, comments, and uploaded files are sent to Google’s Safe Browsing service to check against databases of malicious websites, phishing sites, and malware distribution points. This helps protect your site from security threats.
Data sent to Google includes: 
– URLs extracted from posts, pages, comments, and file content 
– Website URLs being analyzed for reputation 
– No personal information, user data, or site content is transmitted beyond the URLs themselves
Data NOT sent to Google: 
– User personal information or login credentials 
– Post content, comment text, or page content 
– Database information or configuration details 
– User behavior or analytics data
Your Privacy Rights: 
– In the current version (1.0.0), Google Safe Browsing integration is enabled by default for security protection 
– Future plugin updates will include user settings to disable external service usage 
– No data is collected or stored by VMP Fence itself beyond standard WordPress security logs
Third-Party Privacy Policies: 
– Google Safe Browsing API: https://developers.google.com/safe-browsing/v4/usage-limits 
– Google Privacy Policy: https://policies.google.com/privacy
Data Retention: 
VMP Fence caches URL reputation results locally for up to 1 hour to improve performance and reduce external API calls. These cached results are stored only on your server and are automatically purged.
Current Limitation: 
In version 1.0.0, Google Safe Browsing integration is automatically enabled for URL scanning. Future versions will include user settings to control external service usage. If you prefer not to use external services, please contact the plugin developer or wait for the next update which will include privacy controls.
<h3>GitHub WordPress Repository (File Comparison/Diff Viewer)</h3>
Service Purpose: 
VMP Fence connects to GitHub’s raw content service to download original WordPress core files for displaying file differences/comparisons in the admin interface.
Service URLs: 
– Primary: https://raw.githubusercontent.com/WordPress/ 
– Fallback: https://core.svn.wordpress.org/
When This Service Is Called: 
– Only when user clicks “View Differences” button on a scan result 
– Used to show side-by-side comparison of current file vs original WordPress core file 
– NOT called during regular scanning operations or automated processes
Data Sent to GitHub: 
– WordPress version number (e.g., “6.8”) 
– File path relative to WordPress root (e.g., “wp-admin/index.php”) 
– HTTP User-Agent header: “VMPFence Security Scanner” 
– NO personal data, user information, site content, or configuration details are sent
Data Received from GitHub: 
– Original WordPress core file content for comparison and repair 
– Public repository data only (no tracking or analytics)
Privacy Implications: 
– GitHub may log standard web server access logs (IP address, user agent, timestamp) 
– No authentication required – all accessed files are public WordPress core files 
– No data is collected or stored by VMP Fence beyond the file content used for verification
Required: 
– Optional feature – viewing file differences can be skipped 
– Internet connection required only when viewing file comparisons 
– Regular security scanning does not require this service
Third-Party Privacy Policy: 
– GitHub Privacy Statement: https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement
User Control: 
– This feature is only activated when user manually clicks “View Differences” button 
– No automatic background requests are made 
– Users can review scan results without using this feature

VMP Fence Security

Advanced WordPress security plugin with comprehensive malware scanner, vulnerability detection, and multi-layer protection system.

The recent Timthumb.php vulnerability (discussed <a href="http://markmaunder.com/2011/08/02/technical-details-and-scripts-of-the-wordpress-timthumb-php-hack/" rel="nofollow ugc">here</a>) has left scores of unsuspecting bloggers hacked. It’s the perfect combination of not so easy to fix for the technically disinclined, and easy to find and exploit for the malicious – resulting in a disastrous number of compromised sites.
The Timthumb Vulnerability Scanner plugin will scan your entire wp-content directory for instances of any outdated and insecure version of the timthumb script, and give you the option to automatically upgrade them with a single click. Doing so will protect you from hackers looking to exploit this particular vulnerability.
After new, lesser vulnerabilities were found, it became apparent that the plugin needs to be dynamic – able to keep you up to date with the latest version of timthumb, without requiring a plugin upgrade. The plugin now checks for the latest available version of timthumb routinely (each time you visit the scanner page, but no more than once a day), and can download and install the latest version, rather than the one included with the plugin. Scans are run daily (unless you disable them via the options link on the scanner page) via wp-cron to keep up with any new plugins or themes you’ve installed.
