PDF Convert Tab – Distribution Methods

PDF Convert Tab is a standard browser hijacker and web site redirect that is being distributed using the commonly available methods. Like other similar threats it uses several different mechanisms at once to increase the number of infected clients.

At the moment the most noteworthy distribution tactic is its installation from the browser plugin repositories.It is made compatible with the most popular applications and the relevant pages use elaborate descriptions together with fake developer credentials and user reviews.

The hackers behind the PDF Convert Tab redirect can create email SPAM messages that are sent in bulk to the respective users. The messages are composed using social engineering techniques that blackmail, persuade or coerce the users into interacting with the malicious elements. They also serve as one of the primary sources of infected payloads. They are also found on fake download sites that are made with the same templates that are used on the famous Internet portals. Two of the most popular types are the following:

  • Software Installers — The criminals can take the legitimate installers of widely used applications and embed the dangerous virus code into them. Usual targets are system utilities, creativity suites, productivity programs and etc.
  • Documents — The same technique is used to infect documents of different types: spreadsheets, text files, presentations and databases. Once they are opened by the victims a notification prompt appears that asks the victims to enable the built-in scripts (macros). Once this is done the virus infection follows.

The hacker operators can spread the PDF Convert Tab redirect using malicious web scripts such as pop-ups, banners, redirects, in-line hyperlinks and etc.

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.

The active PDF Convert Tab redirect can also be used to execute a hacker-controlled server connection. 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.
  • Bottom Menu Bar — This section of the page is used to link to the privacy policy and terms of use documents.
