Understanding Suspicious URL Probes: How to Protect Your WordPress Site from Common Exploits

In the world of web hosting and online security, one thing is certain: malicious actors are always looking for vulnerabilities to exploit. If you’re using Azure Application Insights or any reporting tool for your WordPress site, you may have noticed suspicious URLs appearing under failure logs. URLs like /server-status, /.git/config, or /.vscode/sftp.json are red flags, often indicating that someone – or something – is probing your site for weaknesses.

In this post, we’ll delve into what these suspicious URL probes mean, why they’re happening, and, most importantly, how to protect your WordPress site from these common exploits.

What Are Suspicious URL Probes?

Suspicious URL probes are automated attempts by bots or malicious users to access specific files or directories on your server. These probes aim to find exposed configuration files, status pages, or misconfigured directories that could leak sensitive information or provide an entry point for attacks.

Common examples include:

• /.git/config: An attempt to access the Git configuration file, which can reveal repository details and potentially sensitive information.
• /.vscode/sftp.json: An attempt to find the VS Code SFTP configuration file, which might contain credentials for remote server access.
• /server-status: A request for the Apache server status page, which, if exposed, can reveal server details and active connections.
• /.well-known/traffic-advice: A less common probe, often related to directory traversal attacks or misconfiguration checks.

Why Are These Probes Happening?

These probes are usually carried out by automated bots scanning the internet for vulnerable websites. The goal is to find:

• Exposed Configuration Files: Files like .git/config or .vscode/sftp.json can contain sensitive data, such as server credentials or internal URLs.
• Server Information: URLs like /server-status can provide detailed server information that an attacker could use to craft more targeted attacks.
• Directory Traversal: Probing paths like /.well-known/traffic-advice might be part of an attempt to access other parts of the server file system.

The Risks Involved

While a 404 error (Page Not Found) might seem harmless, repeated access attempts to these paths indicate that someone is actively looking for vulnerabilities. If any of these files are accidentally exposed, it could lead to severe security breaches, including:

• Unauthorized Access: Exposed configuration files can provide attackers with usernames, passwords, or even API keys.
• Data Theft: Attackers could gain access to sensitive information stored in your server.
• Site Defacement or Takeover: Malicious actors could modify your site or even take it offline.

How to Protect Your WordPress Site

Securing your WordPress site against these types of attacks is crucial. Here’s how you can protect your site:

1. Deny Access to Sensitive Files

• Use your server configuration to block access to hidden files and directories. For Apache servers, you can add the following to your .htaccess file:

<FilesMatch "^\.">
  Require all denied
</FilesMatch>

• For NGINX, add this rule to your configuration:

location ~ /\. {
  deny all;
}

2. Implement a Web Application Firewall (WAF)

• Use a Web Application Firewall like Azure WAF or a plugin like Wordfence for WordPress. These tools can automatically block suspicious requests and protect your site from common exploits.

3. Regularly Monitor Your Logs

• Use tools like Azure Application Insights or any other reporting to monitor your site’s logs and identify any suspicious activity. Set up alerts for repeated access attempts to non-standard URLs.

4. Secure Your Version Control Files

• Never store Git or version control directories within your webroot. These should always be kept outside the publicly accessible file structure.

5. Keep WordPress and Plugins Updated

• Regular updates ensure that your WordPress core, plugins, and themes are patched against known vulnerabilities. Outdated software is a common entry point for attackers.

6. Restrict Access to Server Status Pages

• If you need to access server status pages like /server-status, make sure they are password-protected and restricted to specific IP addresses.

Final Thoughts

Suspicious URL probes are a stark reminder that security is a continuous effort. By understanding these probes and implementing robust security measures, you can safeguard your WordPress site from malicious attacks and keep your data secure.
