Malicious players proved to be really good at harnessing legit online services and applications to their own advantage. As useful as it is, software bundling has become a true scourge over the years, bolstering numerous adware distribution waves. This technique has been weaponized for the umpteenth time, to put it mildly, for spreading a series of hijackers that redirect victims’ traffic to search.yahoo.com.

What is the search.yahoo.com “virus”?
There is an ongoing web traffic monetization campaign that exploits one of the world’s most popular providers of online services, search.yahoo.com. The cybercrooks engaging in this activity have been pimping rogue browser helper objects on a large scale that tweak users’ Internet surfing preferences in order to force hits to a search engine they never opted for. To run this nefarious scheme, the crooks didn’t reinvent the wheel and resorted to the good ol’ bundling hype. The idea is to embed a potentially unwanted program (PUP) into installation clients for regular widespread software, such as common web navigation tools, media downloaders, Java plugins, Adobe Flash Player editions, VPN solutions and the like.
Unsuspecting users may be delighted to spot a free app they were looking for, so most of them will go ahead and click through all the setup steps in a headlong way. Some fine print on one of these steps, though, mentions that an extension like Search Offer powered by Yahoo, or Yahoo toolbar, will be added to their web browsers. Hardly anyone ever pays attention to these technicalities and, as a result, people end up in a loop of constant traffic redirects. The undesired add-on automatically modifies the main browsing preferences, including the default search engine, new tab page and the homepage. It doesn’t take a rocket scientist to understand that the outcome boils down to recurrently visiting search.yahoo.com.
In some cases, the forcibly configured browsing defaults may resolve another pseudo search page, such as go.deepteep.com, search.searchvuzeau.com, search.searchtheweb.today, search.searchucp.com, search.searchidd.com, or go.pajosh.com, mybrowserbar.com. These are dummy domains with no informative value of their own that are set up to capture user hits and further divert all keyword lookup instances to search.yahoo.com. Most of the time, the resulting search results will contain nothing but sponsored links and other forms of advertisements. This gives a clue about the main goal of the criminals – they seek to monetize user hits via ad views and pay-per-click schemes.
An additional caveat to those infected is that the threat actors get access to their sensitive information, such as browsing history, bookmarked sites, and quite possibly even login credentials. At the end of the day, the search.yahoo.com related malware annoys victims a lot, poses risk to their privacy, and therefore should be removed from a contaminated system as soon as possible.
