The Challenge

A national mid-market retailer using WooCommerce on a managed hosting plan discovered that their site had been compromised. Malicious redirects were quietly sending mobile visitors to phishing pages, resulting in a significant drop in conversion rates and triggering a Google ‘Site Deceptive’ warning. The agency managing their account contacted HackProofWP for emergency response under their white-label agreement.

The site processed over 2,400 transactions each month but lacked essential security measures, including a Web Application Firewall and two-factor authentication for admin accounts. Additionally, it was running seven outdated plugins, three of which had known critical vulnerabilities. The client was unaware of how long the breach had been active.

Our Approach

Forensic Analysis
We audited server access logs, file system changes timestamps, and the WordPress database to trace the intrusion vector. The breach originated from an unauthenticated RCE vulnerability in an abandoned plugin.
Malware Removal & Sanitization
All infected files were isolated, cleaned, and compared against clean WordPress core checksums. Backdoors injected into wp-includes and a theme's functions.php were removed.
Hardening
We deployed Cloudflare WAF with custom ruleset tuning, enforced 2FA across all admin accounts, disabled XML-RPC, locked down file permissions, and implemented a Content Security Policy (CSP).
Ongoing Monitoring
The client was enrolled in HackProofWP's managed maintenance plan — including daily malware scans, real-time WAF alerts, and monthly security reports delivered under the agency's branding.
