WebPDFSearch Browser Hijacker – Spread Techniques and Impact

WebPDFSearch is yet another website that hosts a hoax search engine. This site is capable of hijacking the main browsing preferences behind users’ backs. That’s why it is a potentially unwanted program on the one hand. On the other hand, it is a browser hijacker.

The fact that the design of this bogus search engine is simple and intuitive is to make affected users use it for longer. However, do not forget those browser hijackers are apps that primarily aim to generate revenue for their owners. To do so, they activate tracking technologies like cookies and start collecting specific data.

The list below reveals what information may be harvested with the help of tracking technologies like cookies, web beacons, scripts, etc.

  • Visited URLs and websites
  • Browser’s home page
  • Search queries
  • Search queries on the visited web pages
  • Type of used browser
  • Operating system type
  • Internet protocol (IP) address
  • Geographic location
  • The domain name of current Internet service provider (ISP)
  • Diagnostic information which describes how their Services are operating on the system

Harvested data helps WebPDFSearch’s owners to configure advertising campaigns in accordance with your interests and demographics. They hope that with a specific targeting you will be more prone to visit sponsored web pages. Action which will generate higher profits to hijacker’s owners.

It is good to mention here, that some of the presented ads may land on poorly secured or hacked web pages. So, please be careful when interacting with ads generated by WebPDFSearch hijacker.

Another thing to consider is the usage of the searching services this site offers. During our research, we identified that the hijacker is redirecting all search queries to Yahoo search. This issue means that WebPDFSearch is one of those nasty persistent apps that cause the so-called Yahoo Redirect virus.

For the sake of your PC security, it’s best to consider the complete removal of WebPDFSearch from the affected browser and system.
