What is the Optimum Search redirect virus?

Threat actors have always been tempted to look for shortcuts to rake in profits. Out of all these controversial initiatives, manipulating the browser side of computers seems to be one of their favorites. The numerous adware waves that have been breaking out for years and steadily continue to grow are irrefutable evidence of this trend. The elements of this strategy include a strain of malicious code and a treacherous distribution campaign usually relying on software bundles. This is precisely how the new Optimum Search redirect threat works. Its crafty operators have orchestrated a large-scale promotion hoax to deliver the intrusive browser add-on to computers alongside innocuous programs. When on board a system, the virus plagues the victim’s web browser with an imitation helper object while bypassing the permission to do so. This meddling entails recurrent redirects to search.optimum.icu page.

A particularly noxious facet of the Optimum Search hijack in Google Chrome is that the core application creates an enterprise policy and the inscription “Managed by your organization” will complement the standard settings drop-down list. This trick allows it to control the browser and manage the fundamental preferences, including the new tab, homepage, and default search provider. These tweaks are easy to spot: they are visible in the settings interface where the original set-ups end up substituted with search.optimum.icu beyond authorization on the victim’s end. As a result, the browser is literally enslaved and the user’s correct web surfing defaults can no longer be specified in the manual way. The ultimate upshot of this trespass is that the unwanted website becomes the most frequently visited one on the contaminated computer.

At first blush, the destination page doesn’t look dangerous or aggressive. Its design mimics the conventional layout of the average search engine, featuring a bar to enter keyword queries as well as a few standard technicalities such as links to the EULA and Privacy Policy. Nevertheless, there is a catch behind this external mundanity. Search.optimum.icu has no information lookup functionality of its own, so it redistributes all search requests to another service. In the best-case scenario, the redirects will lead to Google, Yahoo, or Bing. There is a less benign course of action, though. The forcibly imposed Optimum Search provider may reroute the browser to junk pages crammed up with ads above the fold, or to outright offensive ones that host drive-by downloads depositing other infections onto the computer.

To top it off, the activity of this unwelcome app can pose a privacy risk. When running inside the host, it collects personally identifiable information in the browser. These details include Internet history, bookmarks, and the sites visited the most recently. The purpose of this ruse is to get an idea of the victim’s interests, which is the basis for serving targeted advertisements down the road. It’s quite possible that passwords and credit card information can also be obtained by the malefactors in charge of the Optimum Search campaign. It goes without saying that this adware attack is a serious issue that needs urgent response. The first step is to get rid of the perpetrating code proper. Then, a number of fixes at the browser level should be applied so that the redirects discontinue.

A quick tip in terms of future prevention of such attacks is to avoid the ‘Express’ option in software installation clients, especially if they are downloaded from suspicious app portals. That’s because the default mode often hides dubious programs that will automatically run with privileges they shouldn’t get. Furthermore, the installation of fishy extras is absolutely inconspicuous in this case. With that in mind, proceed to Optimum Search virus removal covered below.
