Website Security: How to Set Up a Webform to keep your Drupal site secure?
The task of hackers is to get what they want at any cost. Recently, they have developed a very insidious way to steal your data and harm your site with this new malware injection method.
If you do not monitor your site, then everyone who wants to go to it won’t be able to. Your visitors will be warned about a malware issue, and you will gradually lose positions in search engines.
So how does the new malware injection method work?
This new malware injection method targets your file upload fields that were created with the Webform module. If you used this particular module, then you are at risk.
How do hackers do it? In order to harm your site, hackers click the Upload button and add the infected file to your site.
This Upload button allows them to upload files even before submitting the form. They don’t even have to fill out the form, they just attach a non-secure file. So hackers can very easily upload dangerous files to the server and get the URL to it.
Allowing a PDF file to be uploaded to your site increases the risk of hacker attacks. Hackers can upload a PDF containing malware javascript code and executing files.
After adding such a dangerous file to your Drupal site, they will be able to send it to your customers or just random people. As a result of such manipulations, your site will get labeled with a "Dangerous" status, and your rating drops.
Who are the targets for Webform malware?
All Drupal sites that allow visitors to upload PDFs are potential targets for hackers. Therefore, if you have permission to upload PDFs you should learn to protect your Drupal web forms from this new malware injection method.
How to protect Drupal web forms from new malware injection methods?
To protect Drupal web forms from new malware injection, you need to take several steps.
Step 1. Patch the webform module. You should remove the "Ajax Upload button" — find more info here about how to do that.
Step 2. Set a custom path for file uploads on your site. This will help you avoid downloading dangerous files.
Step 3. Clear old Webform submissions
Step 4. Remove all Webform Upload files. If you suspect that you are a victim of a web form malware injection, then you should delete all Webform Upload files and the old custom paths you already set up.
Step 5. Install anti-spam or anti-bot protection on your site. Such a program will protect your site if a bot tries to spam you.
Step 6. Install a virus scanning module. After installing it, all files that are downloaded will be scanned for infection.
