Ecp.yusercontent.com

Ecp.yusercontent.com is a browser hijacker application that relies on questionable distribution techniques to spread itself unnoticed. Indeed, this deceptive behavior commonly associated with this type of PUPs (Potentially Unwanted Programs) has proven to be extremely effective. Thanks to a method known as bundling, many users do not even realize that an additional application will be installed on their systems. Another popular technique involves injecting the PUP inside fake software installers or updaters.

According to the findings of infosec researchers, it appears that the Ecp.yusercontent.com browser hijacker has two versions in circulation - one affecting Mac systems and one for PC users. Both versions will take over the user's Web browsers and modify their settings. More specifically, the homepage, new tab page, and the default search engine will now be set to open an address promoted by the browser-hijacker application.

However, Ecp.yusercontent.com might be promoting different pages. For example, the Mac version leads users to a page with the following message:

'Yahoo! Will be right back… Thank you for your patience'

It implies that there is a problem reaching the legitimate Yahoo search engine. Users are pushed towards buying a fake application that is supposedly capable of resolving the non-existent issue.

Users who notice any of the symptoms associated with Ecp.yusercontent.com should take the appropriate measures to clean their computers from the intrusive application. After all, PUPs also are notorious for having data-harvesting capabilities. Indeed, most of them will spy on the user's browsing activities and then transmit the data to their operators.
