Distribution of Defend Search Redirect
Defend Search is a new malware which has been reported in various attacks worldwide. At the moment the security experts have not been able to identify a single tactic that is being used to infect the targets. We presume that the hackers are using several of the most important methods to carry out the malicious campaigns.
A common way of setting browser hijacker attacks is the use of email spam messages. They may directly distribute malicious file attachments containing scripts that lead to an infection. Other cases can utilize complex social engineering tricks and hyperlinks that are specifically made to confuse the intended targets into infecting themselves. Two more scenarios that are used in combination with email messages rely on infected files used as payloads ‒ documents and software installers.
- Infected Software Installers ‒ The criminals craft malicious packages made out of legitimate software installers. They are taken from the official vendor download sites, modified and then posted on online sites or attached (either as file attachments) or linked in the email messages.
- Infected Documents ‒ They represent dangerous files that usually come in the form of some of the most popular document types: rich text documents, spreadsheets and databases. When the users open them up a notification prompt will ask them to enable the built-in scripts (macros). If this is done then the malware is installed on the victim computer.
The malware browser plugins can be uploaded to hacker-controlled sites and P2P networks like BitTorrent as well. The hacker operators frequently utilize template design, text and images to create portals that look like legitimate download sources. They may also use domain names that are very similar to legitimate sites and advertise them via pop-ups or ad networks.
The browser hijacker code associated with the Defend Search Redirect can be found in numerous malware toolbars. They are usually made for the most popular web browsers: Mozilla Firefox, Google Chrome, Internet Explorer, Safari, Microsoft Edge. They can be distributed on such download sites or even on the browsers repositories (such as the Chrome Web Store for Google Chrome) using fake developer accounts.
Impact of Defend Search Redirect
The Defend Search redirect is a recently discovered malware that follows the standard behavior tactics of browser hijackers. Like other similar threats it is very likely that the site is part of a larger network. One of the primary goals of the attackers is to target users with multiple redirects such as this one in order to gather as much data as possible. The criminal operators aim to create databases containing a detailed profile of the victims.
The infections usually begin by changing important settings on the installed web browsers. The code is compatible with the most popular ones: Mozilla Firefox, Google Chrome, Opera, Safari, Microsoft Edge and Internet Explorer. As malware starts to infect the computer through the applications it can also gain sensitive data from them. Examples include the following: bookmarks, cookies, history, preferences, passwords, form data and account credentials.
Once the users open up their browsers next time they will see the Defend Search home page. It is designed to appear like any one of the famous Interent search engines. Its simple layout display a small logo image along with the search engine box. Underneath it are placed the filter options and on the right side there are shortcuts to several Google services. As it turns out the hackers have customizeed the famous search engine and provided their own version of it.
WARNING! All computer users should know that interacting with such fields will result in sponsored or affiliate links.
Tracking cookies are immediately instituted on the victim computers. They constantly monitor the users behavior and site interaction — all of this is relayed to the hacker operators in real time. In addition they can help with the information gathering phase. The virus is able to extract two main types of data:
- Anonymous Metrics — This kind of data is related mainly to the hardware components of the hosts. The data may be used for statistical purposes.
