identification.com TeamJuly 1, 202520 min read

WordPress powers 43% of the internet in 2025, making it both the world's most popular CMS and its biggest target. With AI-powered attacks, supply chain vulnerabilities, and increasingly sophisticated threat actors, the old "install a security plugin and forget" approach is a recipe for disaster. This comprehensive checklist represents the new baseline for WordPress security—because in 2025, good enough isn't good enough.

The 2025 WordPress Threat Landscape

  • • 94,000 attacks per minute on WordPress sites globally1
  • • 73% of WordPress sites have exploitable vulnerabilities
  • • AI-generated malware that mutates to evade detection
  • • Supply chain attacks targeting popular plugins
  • • Zero-day exploits discovered weekly in the WordPress ecosystem

The Master Checklist: Essential Security Measures

This checklist is organized by priority and implementation complexity. Start with Critical items—these prevent 90% of successful attacks. Then move through High, Medium, and Advanced measures as your security maturity grows.

2025-Specific Threats and Countermeasures

AI-Generated Attacks

The democratization of AI has led to sophisticated, automated attacks that adapt in real-time. Traditional security measures struggle against these evolving threats.

Countermeasures:

  • • Deploy AI-powered security solutions (Wordfence Intelligence, MalCare Pro)
  • • Implement behavioral analysis to detect anomalies
  • • Use challenge-response systems that require human intelligence
  • • Regular security training for all users

Supply Chain Vulnerabilities

Attackers increasingly target popular plugins and themes, injecting malware that affects thousands of sites simultaneously.

Protection Strategies:

  • • Only install plugins from WordPress.org or verified developers
  • • Check plugin update history and developer reputation
  • • Use Web Application Firewall with virtual patching
  • • Monitor WordPress security advisories daily

Quantum Computing Preparedness

While full quantum threats are years away, "harvest now, decrypt later" attacks mean today's encrypted data could be vulnerable in the future.

Future-Proofing Steps:

  • • Implement 4096-bit RSA keys minimum
  • • Plan migration to post-quantum cryptography
  • • Minimize sensitive data retention
  • • Encrypt data at rest with strongest available algorithms

Emergency Response Plan

Despite best efforts, breaches can occur. Having a response plan minimizes damage and speeds recovery.

If Your Site Is Compromised:

  1. 1. Immediate: Take site offline (maintenance mode)
  2. 2. Isolate: Change all passwords (hosting, WordPress, FTP, database)
  3. 3. Communicate: Notify hosting provider and users if data was exposed
  4. 4. Investigate: Use security scanner to identify all infections
  5. 5. Clean: Remove malware using security plugin or professional service
  6. 6. Restore: Use clean backup if cleaning fails
  7. 7. Harden: Implement all critical security measures
  8. 8. Monitor: Watch for reinfection attempts
  9. 9. Document: Record what happened for future prevention
  10. 10. Review: Update security procedures based on lessons learned

Monthly Security Maintenance Schedule
