How to prevent IFrame injections?

Updated on June 28, 2012

In previous hub we learn that what is iframe injection, what is iframe tag and what an attacker can do with Iframe Injection, now in this hub we know how to prevent from iframe injections and malware attack.

How to prevent IFrame injections?

This infection can occur no matter who your hosting company is. To prevent exploitation of web site query caching, site developers must use input validation at every place in their website where they are taking user input. Input validation can prevent a host of exploits and not just this one.

What to do if site is already infected?

Use these regular expressions to search for all pages containing the malicious code and replace it with space:

<iframe src=\"http://[^"]*" width=1 height=1 style=\"visibility:hidden;position:absolute\"></iframe>

echo \"<iframe src=\\\"http://[^"]*\" width=1 height=1 style=\\\"visibility:hidden;position:absolute\\\"></iframe>\"

You may want to write a script to automate this for all the files on the server. However, automated cleaning could break some of your websites. So as of now you will have to clean the files manually.

If you find your site flagged as possibly dangerous in Google results, clean the site. If you already have Google Webmaster Tools set up for your site, log in and from there you can request a review of your site.

If you do not have Webmaster Tools set up, you can set up one at: https://www.google.com/webmasters/tools

Get your site reviewed there. The results will give you further information on cleaning your site and correct SE results. Once the review is positive, Google will remove the blacklisting and allow safe browsing of your site.

Note: the Webmaster Tools setup requires that you insert a verification html file into your site - so don't do the setup until you have cleaned up your site and you've got "safe" access to your site via control panel or FTP.
