How to Safeguard Your Website from Unauthorized Access and Hacks

As a web professional, you may have faced a situation where your website has been 'stolen' or hacked, leading to its rejection by major search engines like Google. This incident can be quite distressing, but with the right approach, you can recover from such an attack and take measures to prevent future occurrences. In this article, we will discuss the steps to recover from a website hack and ways to secure your site from unauthorized access.

The Incident: A Stolen Web Site

It all started one day when my company received a notification that our website had been rejected by Google due to its affiliation with a known spam domain. Initial investigations revealed that someone had exploited a weakness in our DNS settings and taken over a subdomain to conduct a surprise spam campaign. To tackle this issue, we had to collaborate with our hosting provider and make several changes to our DNS settings. Although it was a rare occurrence, it highlighted the importance of monitoring and securing our websites from unauthorized access.

Understanding the Root Cause of the Hack

The first step in recovering from a website hack is to determine the cause of the breach. This involves:

Identifying the software and versions running on your site (e.g., WordPress, Joomla) Note all plugins and themes, including their versions Disabling your site temporarily to prevent further exploitation Executing proper chmod configurations to secure your files

Many website compromises result from outdated software. Therefore, it is crucial to restore your site from a backup. Most web hosting companies have backups from previous months, which you should ask your tech support to restore the database and files. However, despite the restoration, your site remains vulnerable. To ensure security, you must research why it was vulnerable and take necessary actions to fix the issue. Upgrading to the latest versions of software and eliminating unsupported custom plugins and themes can significantly reduce your risks.

Steps to Recover from a Website Hack

1. **Restore from Backup**: If your site was compromised and backups are available from your web hosting provider, ask them to restore the site to a clean state.

2. **Research the Vulnerability**: If backups are unavailable, rely on your own backups or data restored from a different server. Regular backups are essential to prevent data loss due to hacks.

3. **Update Software and Themes**: Always ensure that your site is running the latest versions of software and themes. Remove any custom plugins and themes that are no longer supported or maintained.

4. **Run a Malware Scan**: After restoring your site, run a malware scan (e.g., using maldet) to identify and remove any infected files. This step is crucial to ensure that your site is free from malware.

5. **Change Passwords**: Update all passwords to strong, unique passwords. A good rule is to avoid using dictionary words or sequential numbers. Strong passwords should be a mix of upper and lowercase letters, numbers, and special characters.

Preventing Future Incidents

To prevent future unauthorized access and hacks, consider the following strategies:

Regularly update and patch your software and plugins. Implement strong, unique passwords for all accounts and services associated with your site. Use two-factor authentication (2FA) to add an extra layer of security. Monitor your site regularly for any suspicious activity. Secure your hosting environment with firewalls and security plugins.

By following these steps, you can recover from a website hack and secure your site against future unauthorized access. Remember, your site is your responsibility, and maintaining its security is crucial for its longevity and reputation.
