It doesn’t take a genius to grasp the business model behind hijackers like Youndoo.com. These PUAs (potentially unwanted applications) take control of their victims’ web browsers in order to ensure that certain portions of web traffic are being continuously obtained from all the infected Windows computers. There are tons of interested parties whose wet dream is to get people visiting their online resources without having to take any particular intellectual effort.

When hit by this adware, users experience the following symptoms: their preferred homepage in all browsers morphs into Youndoo.com, and the same applies to such custom settings as the new tab page and default search. The main reason why the victims are puzzled over such a turn of events is that they never sanctioned these modifications. Well, some offending applets don’t need this approval whatsoever. More precisely, they do get the authorization, but inconspicuously. What happens is the person installs some innocuous program off of dubious sites, which ends up also installing the infection as part of the setup wizard’s default preset. Therefore, the targeted user actually agrees to those terms, but these terms may be veiled behind a bunch of screens so that they remain unnoticed.

Youndoo set as Chrome homepage without authorization

The web page of Youndoo.com per se is hard to classify as malware. It is just a replica of a well-known search provider, with an automatic redirect routine triggering whenever any query is entered in the search bar. Ultimately, the infected users do get results for their inquiries, but this takes place via a mediator service they never asked for. The way this infection operates is it drops a persistent browser extension that skips all the conventional approval phases and gets the privileges high enough to mess up the victim’s online routine. One more thing that the adware meddles with is the Target value of various software shortcuts on the system. By doing so, it causes Chrome or Firefox to open up and return Youndoo.com every single time the user launches the program proper.

To top it all off, this infection was found to also harvest the user’s sensitive information, including cookies, sites visiting history, ecommerce activity, and even such details as the IP address, operating system build, and geolocation. This data mining is a background process that’s invisible to the naked eye. The longer the adware stays on board the higher the potential privacy impact. Unfortunately, disabling and deleting the Youndoo add-on via the browser’s settings pane is a futile endeavor. A scheduled system task that the program adds instantly when it enters a PC will reinstate the adverse changes in a matter of seconds. To tackle a problem as intricate as this, the fix needs to be just as nonstandard.
