Google Analytics Referral Spam from go-there1.xyz
On Tuesday, May 21, 2019
go-there1.xyz appeared in my Google Analytics referral list with references to
/h/8714471.html a non-existent page on my site–a clear indication that this is a spoofed referral spam attack where no one touched my site, or if they did, they were referred to a non-existent page. Other sites may have a reference to a different page of the same format.
whois go-there1.xyz shows registration on May 21, 2019 (today) at
namesilo.com. The domain was registered at 5:26 AM UTC, or 8:26 AM in Kiev. Prior to about March, 2019 most referral spam domains were registered with ukrnames, but as of about March, 2019, most are registered with namesilo, and are registered a few hours earlier in the day. Also as of March 2019, the domain names are not as readable to native English speakers.
curl -L go-there1.xyz | grep 'semalt' shows references to semalt.com, a big referral spam name a couple of years ago. The signature for this is slightly different than recent
semalt.com attack sites:
<iframe src="http://semalt.com/fbpc.php" style="position:absolute;top:0;left:0" width="1" height="1"></iframe>
DNSLytics.com shows that this is a route to IP address
22.214.171.124. This server is owned by “openfrost.com”, a domain that is privately registered with
ukrnames.com, a registrar that is used by numerous recent Google Analytics referral spam attacks.
Google has become better at detecting but not blocking analytics attacks from this organization. Generally, these referrals now disappear within a couple of days, even though the view that I use for identifying referral spam does not use filters. Given that the extremely high ratio of self-promotion of semalt.com vs. other real web sites, it appears that this may have more to do with placing malware than with selling black-hat SEO services.

Fixing the Problem
My first reaction in addressing referral spam was to add a line to .htaccess to block these spam referrals (see http://www.htaccess-guide.com/deny-visitors-by-referrer/ for a description of how to do this) but with more research, it turns out these referrals weren’t referrals to my site at all, but were insertions of fake referrals into my Google Analytics reports. As was the case with
darodar.com, the clear intent is to cause webmasters to go to an unfamiliar site when they see a reference in their Google Analytics reports. Whether the motivation is to generate traffic to their site or to cause webmasters to visit a site that will download malware is unknown.
Based upon the instructions in Removing Referral Spam from Google Analytics, I checked the hostname on the referrals, and all showed “(not set)”–a clear sign that no one ever touched my site and that these were inserted into Google Analytics to get me to click
social-buttons.com to generate traffic or download malware onto my computer.
Removing Referral Spam from Google Analytics provides a good description of the problem and some solutions. Understanding and eliminating referrer spam in Google Analytics gives another good description of referral spam and a programmatic solution that is appropriate for plug-in developers but not for administrators of WordPress, Joomla and other content management system (CMS) based sites.
An alternative is to switch to self-hosted Piwik for your web analytics; if you do this, it will be immediately clear that the vast majority of Google Analytics referral spam is of the spoofed variety rather than the crawler variety. Piwik does not have the advertising integration nor does it have the demographic information, but for many small-traffic sites it can provide much more information. See Using Piwik as an Alternative to Google Analytics on this web site for more information on why Piwik might work for you and how to implement it.
