The specialists of Sucuri company have been monitoring for a long time one malicious enterprise, the roots of which belong to domain. Sure thing that this domain has nothing to do with the Cloudflare company, but fraudulent scripts use exactly this source for spreading. They have the same principle as keyloggers, which consists in stealing all the sensitive data of users. Sometimes, such scripts can load different cryptocurrency miners on the already infected sites.

In April 2017 analytics have noticed such campaign for the first time. Along with advertising banners, a malicious JavaScript penetrated into compromised sites. Recently, there was the second incident, in November 2017. The same hackers, but a slightly changed strategy: malicious scripts begin to disguise as jQuery and Google Analytics JavaScript. Actually, they represent Coinhive web miner. According to researches of analytics, this campaign infected 1833 sites.
The investigators reported that hackers change their tactic again. The scripts are still doing mining thanks to the visitors of compromised sites. Besides, the features of keyloggers are already used in their strategy.
