#NoHacked: Identifying and Diagnosing Injected Gibberish URL Hacking

Hackers can turn your nondescript website into a malicious spy bot in a matter of minutes, sending sensitive user data to hackers without your even realizing it. Worse, they can hack into your website databases and destroy or manipulate important information, injecting your content with malicious links and even hijack the hosting server to be used in botnet DDoS attacks.

But enough of this scare fest. It’s not all doom and gloom out there on the Web. There are things that you can do to secure your website from hackers and becoming a target for online vandals.

How do you identify and diagnose a trending hack? Even if your site is not infected with a specific trending hack, many of the below steps can be helpful for other types of hacks.

The hallmark of this type of hacking is spammy pages that appear to be added to the site. These pages contain keyword-rich gibberish text, links, and images in order to manipulate search engines. For example, the hack creates pages like www.example.com/pf/download-2012-free-full-crack.html which contain gibberish content like below:

Cloaking

This hack often uses cloaking to avoid webmasters from detecting it. Cloaking refers to the practice of presenting different content or URLs to webmasters, visitors, and search engines. For example, the webmaster of the site might be shown an empty or HTTP 404 page which would lead the webmaster to believe the hack is no longer present. However, users who visit the page from search results will still be redirected to spammy pages, and search engines that crawl the site will still be presented with gibberish content.

Monitoring your Site:

Properly monitoring your site for hacking allows you to remedy the hack more quickly and minimize damage the hack might cause. There are several ways you can monitor your site for this particular hack.

Looking for a surge in website traffic

Because this hack creates many keyword heavy URLs that are crawled by search engines, check to see if there was any recent, unexpected surges in traffic. If you do see a surge, use the Search Analytics tool in Search Console to investigate whether or not hacked pages are the source of the unusual website traffic.

Tracking your site appearance in search results

Periodically checking how your site appears in search results is good practice for all webmasters. It also allows you to spot symptoms of hacking. You can check your site in Google by using the site: operator on your site (i.e. search for site:example.com). If you see any gibberish links associated with your site or a label that says “This site may be hacked.”, your site might have been compromised.

Signing up for alerts from Google

We recommend you sign up for Search Console. In Search Console, you can check if Google has detected any hacked pages on your site by looking in the Manual Actions Viewer or Security Issues report. Search Console will also message you if Google has detected any hacked pages on your site.

Also, we recommend you set up Google Alerts for your site. Google Alerts will email you if Google finds new results for a search query. For example, you can set up a Google Alert for your site in conjunction with common spammy terms like [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][site:example.com cheap software]. If you receive an email that Google has returned a new query for that term, you should immediately check what pages on your site are triggering that alert.

Diagnosing your Site

Gathering tools that can help

In Search Console, you have access to the Fetch as Google tool in Search Console. The Fetch as Google tool allows you to see a page as Google sees it. This will help you to identify cloaked hacked pages. Additional tools from others, both paid and free, are listed in the appendix to this post.

Checking for hacked pages

If you’re not sure if there is hacked content on your site, the Google Hacked Troubleshooter can walk you through some basic checks. For this type of hack, you’ll want to perform a site: search on your site. Look for suspicious pages and URLs loaded with strange keywords in the search results. If you have a large number of pages on your site, you might need to try a more targeted query. Find common spam terms and append them to your site: search query like [site:example.com cheap software]. Try this with several spammy terms to see if any results show up.

Checking for cloaking on hacked pages

Because this type of hacking employs cloaking to prevent accurate detection, it’s very important that you use the Fetch as Google tool in Search Console to check the spammy pages you found in the previous step. Remember, cloaked pages can show you an HTTP 404 page that tricks you into thinking the hack is fixed even if the page is still live. You should also use Fetch as Google on your homepage as well. This type of hack often adds text or links to the homepage.

Appendix

These are tools that scan your site and may be able to find problematic content. Other than VirusTotal, Google doesn’t run or support them.

Virus Total, Aw-snap.info, Sucuri Site Check, Wepawet: These are tools that may be able to scan your site for problematic content. Keep in mind that these scanners can’t guarantee that they will identify every type of problematic content.
