1-free-share-buttons(.)com Spam – How Did I Get It

Spam, originating from 1-free-share-buttons(.)com and related domains is generally divided in two types:

Type 1 – Web Crawlers

These type of spammed URLs are also known as spiders or crawlers. The primary reason for that is the bots crawl set of pre-configured web pages, most likely researched previously be the spammers. One tool to research them is called Google Dorking(https://sensorstechforum.com/drupal-ransomware-uses-sql-injection-lock-drupal-websites/) which is also used by some web-based ransomware infections. Google Dorking includes checking websites for different criteria, such as:

  • Bugs and vulnerable site files.
  • Exploits allowing hackers to bypass captcha via the spam bots.
  • Websites that have different vulnerable directories or secret such.
  • Sites that have unsecured servers in terms of spam.
  • Sites that have specific traffic criteria.

Based on this and other information, the spammers may pre-program the spam bot to look for specific websites to spam. However, using web crawlers is generally a spam method that does not have a very long lifecycle and while massive, the spam stops once a domain or host IP addresses associated with the spam bot are flagged.

Type 2 – Ghost Referrals

Ghost Referrer spam, also known as Ghost Referral is reported to be more sophisticated than your average web crawler. This is due to the fact that this type of spam takes advantage of the HTTP protocol which allows the bot to spam while not even being logically present in the site, without even having to enter captcha and other security passes. Experts claim that this type of spam can quickly devaluate the website statistics and may still be present after being blocked, like an invisible ghost sitting there.
