Pdfmaster.net – Detailed Overview
After infection files associated with Pdfmaster.net are started on the PC, several modifications of basic browser settings are initiated. These changes enable the hijacker to replace the homepage, new tab page and default search engine in all targeted web browsers. So that was the moment when the first thing you see when you open your preferred web browser became the main page of the hijacker as shown below:
At first, you may consider that Pdfmaster.net is a normal website that provides web searching services as well as a few convenient features for converting PDF files and quick access to several popular websites. However, don’t forget that it is not an app that appears in your browser by your wish. Now let us reveal some of the reasons why this program is better to be removed than kept.
As revealed in the policy of this hijacker one of its primary goals is data collection. So as long as it has access to your browser it is able to obtain certain details (more about them you could find in the next paragraph) and send it to its servers. It is most likely that the data will be used for the creation of profile based on your interests that will be later on used for targeted advertising campaigns. So there is a chance that an infection with this PUP will lead to an increased number of ads in the browser.
On the one hand, these ads may make your browser sluggish and even unresponsive at times. On the other hand, some of them may land you on corrupted web pages that are set to automatically trigger severe malware infections directly on your PC.
Furthermore, you should have in mind that in case of infection with Pdfmaster.net there is real chance that an undesired extension has also been installed without asking you for permission. And once this extension is added to your Google Chrome browser it can:
- Read and change all your data on the websites you visit
- Replace the page you see when opening a new tab
- Change your search settings to: photorito.me
- Detect your physical location
The need to reveal the policy section of Pdfmaster.net in detail is the information about data collection practices revealed there as well as the name of the company which is responsible for storing valuable data of yours.
So let’s begin with stating that the company owner of this deceptive website is stated to be AIR TB & CONSULTING LTD. Our research history indicates that Pdfmaster.net is not the first nasty hijacker associated with this company. As reported, other two browser hijackers dubbed Photorito.me and Pdfconverter.pro are owned by AIR TB & CONSULTING LTD.
As stated in the policies of their products including the policy of Pdfmaster.net they use them to collect a variety of personal and non-personal data from the browsers of all users who are using their deceptive services.
Eventually, it appears that as long as you keep Pdfmaster.net present in your browser it takes your agreement for data collection for granted. So all of the details listed below will be sent to the hijacker’s servers and this way provided to its owners:
- The searches you perform
- The pages you view
- Your name
- Email address
- Country of origin
- Browser type
- Telephone number
- Household income
- Zip code
- All search queries and visited websites
A disturbing consequence is that the records of your data could be disclosed to third-party services or businesses partners of AIR TB & CONSULTING LTD whose names and activities are unfortunately unknown. The chances are that the data will be used for targeted advertising or at worst malware attacks. And in case that some of the holders don’t store the data in a secure manner, malicious intenders may also obtain all these sensitive details of yours.
