Executive Summary

This case study details the manual process undertaken to remove a virus from the code of wordpress themes, plugins, and core files within the wp-admin and wp-includes folders. The website was crucial for the client and had been compromised, leading to potential security vulnerabilities and performance issues. The objective was to manually identify and remove the malicious code, secure the website, and restore normal operation without data loss.

Background

  • Client: A business utilizing a WordPress website for content management and communication.
  • Problem Statement: The website was infected with a virus that compromised the code in themes, plugins, and core files in the wp-admin and wp-includes folders. This resulted in security vulnerabilities and unauthorized access, posing significant risks. The links on the pages were redirecting to unknown pages.
  • Objective: The primary goal was to manually remove the virus from all infected files, restore the website’s functionality, and implement measures to prevent future infections.

Challenges

1. Identifying Infected Files:

  • The virus had spread across various parts of the website, making it difficult to pinpoint all infected files.
  • Hidden malicious code was embedded within legitimate code, complicating detection.

2. Restoring Functionality:

  • Ensuring that cleaning the infected files did not disrupt the website’s functionality.
  • Preventing data loss during the cleaning process.

3. Preventing Future Infections:

  • Implementing security measures to protect the website from future attacks.

Solutions Implemented

1. Manual Identification and Inspection

Initial Assessment:

  • Conducted an initial assessment to understand the extent of the infection.
  • Reviewed recent changes and suspicious activities reported by the client.

Code Review:

  • Manually inspected the code in all themes, plugins, and WordPress core files (wp-admin and wp-includes).
  • Searched for common indicators of malicious code, such as obfuscated scripts, unauthorized file modifications, and unusual code structures.

2. Manual Identification and Inspection

Theme and Plugin Cleaning:

  • Carefully examined each theme and plugin file for malicious code.
  • Removed or cleaned infected files, ensuring to preserve the necessary functionality.

Core File Restoration:

  • Replaced compromised core files in the wp-admin and wp-includes directories with clean versions from a fresh WordPress installation.
  • Verified that all core files matched the original WordPress source to ensure integrity.

3. Restoration and Hardening

Database Inspection and Cleaning:

  • Scanned the database for any injected malicious code or unauthorized changes.
  • Cleaned and restored the database to ensure it was free from infection.

4. Monitoring and Maintenance

Continuous Monitoring:

  • Set up manual monitoring practices to regularly check the integrity of the website.
  • Scheduled periodic reviews to detect any signs of reinfection or suspicious activity.

Backup Solutions:

  • Implemented a regular backup schedule to ensure quick recovery in case of future infections.
  • Stored backups securely off-site.

4. User Education and Best Practices

Training:

  • Educated the client and their team on best practices for maintaining website security.
  • Provided guidelines on recognizing phishing attempts and avoiding unsafe plugins or themes.

Documentation:

  • Implemented a regular backup schedule to ensure quick recovery in case of future infections.

Results

Virus Eradication and Security Improvement:

  • Successfully removed all instances of the virus from themes, plugins, and core files.
  • Restored the website to full functionality without data loss.

Enhanced Security Posture:

  • Hardened website security to prevent future infections.
  • Continuous monitoring and regular updates ensured ongoing protection.

Client Satisfaction:

  • Improved website performance and user experience.
  • Enhanced client confidence in the security and reliability of their website.

Conclusion/Future Scope
