Today’s web search landscape is versatile, with a vast range of keyword lookup services being available to end users. All it takes to use a specific provider on a permanent basis is some simple toggling of browser preferences. But what if a certain page, such as Nefryhok Search, keeps popping up in a browser without being configured as the default engine? This, most likely, is an effect of adware activity on the PC.
Cybercrooks who seek profit through monetization of almost effortless web traffic will definitely find the Nefryhok app useful. Hosted at nefryhok.xyz domain, this solution allows would-be threat actors to build a browser hijacking service of their own and configure it as they deem appropriate. The aggressive essence of this product lies in the fact that users’ choice is put entirely out of the equation. It means that anyone who has this offending browser plugin on board their machine will be forced to visit Nefryhok Search page off and on, although they never opted into such a feature. The proliferation of this adware is a function of bundled setups, where people install freeware or shareware along with drive-by extras. The installation wizard may contain an indication of ‘featured’ products being promoted alongside the main software, but it tends to be an inconspicuous part of the recommended setup option.
Nefryhok is a cross-browser piece of code. Therefore, its impact covers most of the popular online navigation suites, including Chrome, Firefox and Internet Explorer. Once a user unknowingly authorizes it to appear on their computer, it gets attached to the default browser and instantly takes over the Internet preferences. In particular, custom URLs for the homepage, new tab page and search provider get replaced with nefryhok.xyz/nefryhok.nefryhok.php. It’s easy to predict the outcome of this interference – the victim will be visiting said site when performing customary actions, such as opening the browser, opening a new tab within the same window, and trying to find random information online by typing their query in the address bar directly.
The landing page itself is not involved in covert distribution of malware. It is a primitive website that contains nothing but a field for custom search powered by the world’s most popular search engine. The service, though, returns a fusion of relevant results and ads. The sponsored links may populate the right-hand part of the SERPs (search engine results pages) or appear at the top. The operators of a specific malvertising campaign over Nefryhok virus can configure the contents of these pages in favor of certain advertisers with whom they have a mutually beneficial relationship. Unfortunately, the only party that suffers from such a cooperation is the actual end user, because the control of browsing preferences slips out of their hands. A serious problem in this context is that this infection is only being detected by a few antimalware tools at this point, which explains its rapid propagation. If hit by Nefryhok, be sure to use the instructions below and bid farewell to the fraudulent traffic interception entity.
