PDF Convert Tab – Detailed Description
The PDF Convert Tab redirect is mainly delivered using a browser hijacker which presents several web browser changes. As the infections stems from the hijacker, it can instantly access all stored contents within: cookies, bookmarks, history, passwords, settings and etc. Once the threat is installed on the client machines it will change the default settings to point to the hacker-controlled site: default home page, new tabs page and search engine.
Depending on the exact configuration of the threat and its intended targets it can cause different effects on the machines. In many cases this includes the Windows Registry where the redirect can target both entries belonging to the operating system or the user-installed applications. When the Windows registry is changed overall performance can suffer while changes to the individual application strings can result in the disruption of certain functions.

It leads to a Trojan-like infection where the criminal operators can spy on the victims in real time, as well as take over control of the machines. This can be used to install additional threats to the victim hosts as well.
Once the hijacker is installed on the victim browsers it will instantly redirect the users to the target site. Similar redirects like this one usually contain a pre-generated list of addresses that are placed in its engine.
When the associated web browser is started for the first time an information gathering module is started. It is able to harvest sensitive data from the target computers which is grouped into two main categories:
- Privacy-Invasive Data — The engine is configured to harvest strings that can directly expose the identity of the victims: their name address, location, interests, telephone number, passwords and etc.
- Campaign Metrics — The engine can be configured to extract information that can optimize the distribution campaigns. Example data includes the a complete profile of the installed hardware components.
The browser redirect shows a typical search engine template that includes options for converting files to PDF using a third party service. It is devised of several elements:
- Top Menu Bar — It includes a search engine box that uses the same engine as the main one placed in the center.
- Main Search Engine — It is the main interactive element of the page. It aims to attact the redirected users into using it.
An example is the collection of the following data:
- Social Media Accounts & Usage — Whenever a social media service is accessed through the relevant browser hijacker the user data can be accessed by the service as well.
- Email Data — If the PDF Convert Tab redirect links the users to an affiliate email service all of the inbox contents can be made accessible to them.
- Other Sites Interactions — The tracking cookies can give the operators an overview of the victim’s usage of all web sites, not just the ones that they directly control.
