IX Server Security Scan - Smart Slider 3 Pro

Date: April 11, 2026

Scan Purpose

Security audit of all WordPress installations on IX server following the Smart Slider 3 Pro supply chain attack (April 7-9, 2026).

Executive Summary

[SUCCESS] NO COMPROMISED PLUGINS FOUND

  • Total WordPress sites scanned: 87
  • Smart Slider 3 PRO installations: 0 (GOOD - this was the compromised version)
  • Smart Slider 3 FREE installations: 3 (SAFE - free version was not affected)

Risk Level: LOW - No exposure to the April 7-9 supply chain attack

Background: Smart Slider 3 Pro Attack

The Vulnerability

  • Attack Window: April 7-9, 2026
  • Target: Smart Slider 3 Pro WordPress plugin
  • Attack Type: Supply chain attack via compromised update system
  • Impact: Sites that updated during the 6-hour window received "fully weaponized remote access toolkit"
  • Scope: Potentially thousands of sites worldwide

Attack Details

  • Threat actors hijacked the plugin's UPDATE mechanism
  • Users thought they were getting security patches
  • Instead received remote access backdoor
  • Detected approximately 6 hours after deployment
  • WordPress powers ~43% of all websites globally

Scan Results

Scan Methodology

  • Server: IX (172.16.3.10)
  • Method: Filesystem scan of all cPanel accounts
  • Command: find /home/*/public_html -name "wp-config.php"
  • Script: /root/scan_smart_slider.sh
  • Scan completed: April 11, 2026 05:09 AM MST

WordPress Sites Inventory

Total sites found: 87

This confirms IX server hosts a significant number of WordPress installations (previously documented as "40+" in credentials.md).

Smart Slider Installations Found

1. ComputerGuruMe - Moran Client Site

  • User: computergurume
  • Path: /home/computergurume/public_html/clients/moran
  • Version: Smart Slider 3 (Free) 3.5.1.27
  • Status: SAFE (free version not affected by attack)

2. Photonic Apps

  • User: photonicapps
  • Path: /home/photonicapps/public_html
  • Version: Smart Slider 3 (Free) 3.5.1.28
  • Status: SAFE (free version not affected by attack)

3. Thrive

  • User: thrive
  • Path: /home/thrive/public_html
  • Version: Smart Slider 3 (Free) 3.5.1.28
  • Status: SAFE (free version not affected by attack)

Risk Assessment

Current Risk: LOW

Rationale:

  1. No Smart Slider 3 PRO installations found

    • The PRO version was the target of the supply chain attack
    • Free version uses different update mechanism
    • Free version was NOT compromised

  2. Free version installations are outdated but safe

    • Versions 3.5.1.27 and 3.5.1.28 are older
    • Should be updated for general security/features
    • But NOT urgent security risk from this specific attack

  3. No exposure during attack window

    • Since no PRO version installed, no sites could have received the backdoor
    • No sites at risk from this specific compromise

Recommendations

Immediate Actions (Optional - Low Priority)

  1. Update Smart Slider 3 Free on the 3 affected sites:
    • computergurume/moran
    • photonicapps
    • thrive
    • Latest version: Check WordPress plugin repository
    • Priority: LOW (general best practice, not urgent security issue)

Monitoring Actions

  1. Subscribe to WordPress security bulletins

    • Monitor for similar supply chain attacks
    • Watch for plugin compromise announcements

  2. Implement plugin update policy

    • Consider staging environment for plugin updates
    • Wait 24-48 hours after updates released before applying to production
    • This delay would have avoided the 6-hour attack window

  3. Regular security scans

    • Schedule quarterly plugin audits
    • Check for outdated/abandoned plugins
    • Remove unused plugins

Best Practices Going Forward

  1. Minimize plugin footprint

    • Only install necessary plugins
    • Remove/disable unused plugins
    • Fewer plugins = smaller attack surface

  2. Plugin vetting process

    • Check plugin update frequency
    • Verify developer reputation
    • Review number of active installations
    • Check support forum activity

  3. Backup strategy

    • Ensure all 87 WordPress sites have current backups
    • Test restore procedures
    • Keep backups isolated from production
