How Is ShareButton Spam Spread
The domains spreading the ShareButton spam are multiple:
These domains may spread the ShareButton plugin via either using affiliates that generate revenue by spreading them or post them in return for a compensation on different places online or automatically.
The automatic distribution strategy may be used in the case of the Sharebutton domains because they are believed to spread via two primary types of spamming software also known as spam bots.
Type 1: Web Crawler Spam
Also known as Spiders, this type of spamming software uses a pre-programmed list of websites on which it spams referrals under a ghost account. Since this particular type of spam is spread on websites that contain low-quality security, the cyber-criminals may have used a method, known as Google Dorking. This method involves using scripts to perform searches in google for specific types of websites based on what security features they have. This technique could be combined together with the spamming software which also has the same feature based on dorking – to crawl the web for web-sites based on a pre-configured criteria which could be dorking code as well.
Whatever the case may be, the Web Crawler bots are more oriented towards spamming massively on different websites, than remaining persistent on one site. In addition to this they are also easier to be blocked primarily because they are not so persistent. But if they are combined with other spamming tools, they become very dangerous.
Type 2: Ghost Referrer Spam
Also known as Ghost Referrals, this type of spam is named like this for a purposes. The spamming software aims to target a specific website and while it is spamming it aims to do it as remotely as possible, without having to be directly connected to the website being spammed with Sharebutton URL’s. This technique is more effective than Web Crawlers because it uses sophisticated combination of exploiting the free HTTP protocol and connect remotely to the website it aims to spam with web links. This makes banning the spammer significantly harder because his source IP address may easily be changed often or obfuscated.
Fact is, that both spam methods are being used more and more often and can quickly render the data about traffic on your website useless.
ShareButton Domains In-Depth
The attacks related to the ShareButton domains exist for quite some time now and they are created for several different purposes. One of those purposes is to generate traffic to websites that are third-party and want to be boosted and sold online with high traffic that is actually a hoax. Another goal of referral spam may be to spam not only ShareButton as a service but also generate custom URLs that redirect the users to malicious sites. This means that the web links may contain malware and even ransomware, like Cerber v4, for example, which holds your files hostage until you pay a hefty sum to get them unlocked.
The network of domains that lead to the ShareButton web page has been reported by security experts to be potentially harmful, so all users of your website who have clicked on such URLs are advised to perform an anti-malware scan to see if they have been infected by malware:
The other primary purpose of redistributing referral spam is to promote the suspicious plugin of sharing buttons that ShareButton advertises. This plugin may obtain crucial user information and may redirect your users not to the actual social media websites, but to phishing websites that may be fraudulent and phishing and may steal the login information, so users, beware what you click on.
