What changed for this project

These results come from this project record. They describe this project and do not guarantee the same outcome for another website.

Malware Files Removed

100% Clean

60+ Backdoors

Every webshell, obfuscated injection, and cron-based re-infector was identified and purged.

Google Warning Lifted

72h Recovery

72 Hours

Google's 'This site may be hacked' manual action was lifted within 3 days of our cleanup.

Organic Traffic Recovery

Full Recovery

+340%

Traffic returned to pre-hack levels within 4 weeks and exceeded them within 8 weeks.

01 / The challenge

The client’s challenge

The client's WordPress site was compromised with a Japanese keyword hack — injecting thousands of spam pages into Google's index, redirecting organic visitors to phishing sites, and triggering Google's 'This site may be hacked' warning. Organic traffic dropped 90% within days.

02 / The approach

The approach and implementation

We performed emergency malware removal (60+ backdoor files), cleaned the database of injected spam content, submitted removal requests for spam-indexed URLs, and deployed server-level WAF rules with file integrity monitoring to prevent re-infection. Google's manual action was lifted within 72 hours of our reconsideration request.

The Challenge

A compromised website is a digital emergency that threatens a brand's reputation, its SEO rankings, and its users' safety. This WordPress site came to us under a severe, targeted brute-force attack. The attackers had bypassed standard registration filters to automatically generate multiple rogue administrator accounts using automated bot emails. The fallout was extensive: the database was bloated with over 6,000 injected spam posts, and malicious code was deeply embedded within the site's architecture. The immediate goal was not only to stop the active bleed, but to completely overhaul the site's security posture so it could never happen again.

The Solution

Our team executed a systematic, multi-layered triage and recovery protocol. First, we quarantined the environment and conducted a granular audit of the WordPress core, themes, and plugins to isolate and permanently remove every trace of malicious code and backdoors. With the file system clean, we tackled the compromised database: a rigorous optimization pass that surgically purged the 6,000+ spam posts, deleted the rogue user accounts, and cleared out the orphaned metadata dragging down performance.

With the infection cleared, we hardened the perimeter. Knowing that standard registration filters had already failed once, we masked and protected the default WordPress login URL to instantly neutralize automated brute-force scripts. Finally, we implemented strict HTTP security headers to protect against cross-site scripting (XSS) and clickjacking, ensuring the server rejects malicious payloads before they ever reach the application layer.

Results at a Glance

  • 6,000+ injected spam posts purged from the database
  • All rogue admin accounts and backdoors identified and removed
  • Zero data loss — all legitimate content and settings preserved
  • Dramatically faster load times after database optimization
  • Zero reinfection since hardening — brute-force traffic fully neutralized

The Outcome

The website was restored to a clean, highly secure state with zero data loss for legitimate content. Aggressively clearing the spam and optimizing the database dramatically improved loading speed, while the protected login architecture and strict security headers neutralized the ongoing bot traffic entirely. The site owner walked away with long-term stability, peace of mind, and a fortified defense against future attacks.
