What Is Referral Spam?
Referral spam, also known as referral traffic spam or referral ghost spam, is a type of spamming technique used to generate fake website traffic by manipulating website analytics. In this practice, spammers send fake data to a website’s analytics tools, making it appear as if the traffic is coming from legitimate referrals. This can lead to bad SEO and other types of consequences for the website being targeted.

How Do Spam Links Distribute
Since the spammers behind this refferal spam have used a massive spam campaign, according to researchers, the spammers may have used two types of spamming software:
Web Crawlers or Spiders
This type of spamming software “crawls” though different pages to collect information about how often are the sites of those pages modified by administrators and other criteria. After it has gathered enough data, it may initiate a massive spam campaign on certain URLs, previously assigned to it from a specific “hitlist”.
And what is worse is that reports by Incapsula indicate that when official Google bots crawl to scan for web links they begin to index the referral spammed web links and therefore boost the SEO of the spammed web site, in this case, Semalt.
Ghost Referral Spam
Even though it has not been officially confirmed, Semalt Referral Spam may also be redistributed via ghost referrals. Such spam is more sophisticated and more targeted than massive. It takes advantage of the free HTTP protocol to connect remotely to the website and spam while not even being on the website itself. It is extremely effective and is very hard to be removed.
Both off those spam methods can be utilized via very expensive spam campaigns, and they are something you DO NOT want to have on your website. Besides regular checks for spam, they should be permanently blocked on your web server because they have the potential to quickly devaluate the data of Google Analytics websites. And the damage done by such spammed URLs may even be more. For example, Ghost Referrals can target specific aspects of Google Analytics data to devaluate. And not only this, but it may also lead to malicious web pages that may infect the users of the website with malware, and make them never come back to your site again.
More Information About the Semalt Referral Spam
As soon as the spam is initiated, it may be in messages that contain web links which originate from the following domains:
- https://semalt.semalt(.)com
- HTTP:// keywords-monitoring-your-success.com
- HTTP:// free-video-tool.com
Also, researchers have identified that the following IP addresses were belonging to spam bots spreading web links redirecting to Semalt’s main web page:
- 186.214.178.98
- 24.218.171.58
- 79.49.195.113
- 187.112.50.169
In addition to that, the spammers are reported to use a very dangerous software, called QtWebKit, which allows them to perform different activities, like executing different JavaScript. Also, further reports indicate that these spam bots may be doing the spamming from infected machines and hence be spread via different malware, like botnet malware, for example. Malware researchers report that Semalt may have used the Soundfrost botnet which might have allowed them to infect hundreds of thousands of computers all over the world, primarily in South America.
