The site displays a Dangerous site warning

If you’re a developer and your site is showing a “Dangerous site” warning, here are steps to help resolve the issue:

1. Check the HTTPS Certificate:

   • Ensure the site uses a valid HTTPS certificate (SSL/TLS). If the certificate is invalid or expired, users will get a security warning.
   • Renew the certificate if it’s expired and update the site configuration to enforce HTTPS on all pages.

2. Scan the Site for Malware:

   • Use tools like Sucuri or VirusTotal to scan your site for potential malware or malicious scripts.
   • Remove or fix any malicious code found on the site.

3. Check Google Search Console:

   • If the site is registered in Google Search Console, check for security messages or malware warnings.
   • Google often flags sites as unsafe if they contain malware, phishing, or other threats. After fixing the issue, submit a review request to have Google remove the warning.

4. Update All Site Components:

   • Update all libraries, plugins, themes, or CMS platforms used on the site, such as WordPress, Drupal, or Joomla.
   • Outdated software can have security vulnerabilities that allow attackers to compromise the site.

5. Implement Protection Against Malicious Attacks:

   • Enable protection like a Web Application Firewall (WAF), available from services like Cloudflare, Sucuri, or AWS WAF.
   • This protection can help block malicious requests before they reach your site.

6. Perform a Security Audit of the Code:

   • Review your code for vulnerabilities like SQL injection, XSS (Cross-Site Scripting), or CSRF (Cross-Site Request Forgery).
   • Using static code analysis or automated security check tools, you can identify and resolve potential threats.

7. Scan the Server for Compromised Files:

   • If you have server access, scan it for compromised or unknown files that might be causing security warnings.
   • Check and clean directories such as /tmp, /uploads, and others where malicious code often hides.

8. Request a Site Re-Evaluation:

   • After fixing all potential issues, request a re-evaluation of your site from search engines like Google, Microsoft, or others. For example, use Google Search Console for Google and Bing Webmaster Tools for Bing.

Following these steps should help remove the unsafe label and ensure that visitors do not see “Dangerous site” warnings when accessing your website.
