pcbooster.biz Browser Hijacker Overview

pcbooster.biz is a new malicious site that is used alongside with several web redirects and scripts. Dangerous add-ons have also contributed to the creation of a pcbooster.biz browser hijacker that is distributed on different hacker-controlled download sites. Upon infection with them the settings of the relevant web browsers are changed. This includes the most popular applications: Mozilla Firefox, Google Chrome, Safari, Opera, Internet Explorer and Microsoft Edge.

Such actions also pose a danger to the privacy of the affected victims as the add-ons are able to extract sensitive information that is relayed to the hacker operators. Examples include the stored cookies, history, bookmarks, passwords, account credentials and settings. This makes the pcbooster.biz browser hijacker a very useful tool for ID theft. Its goal is to redirect the victims by changing the default search engine, new tabs page or home page to the hacker-controlled site.

The aim of the pcbooster.biz browser hijacker operators is to redirect the users to their site. It is used to offer affiliate computer applications. At the moment a system utility is being offered using a template that resembles a genuine download site. To further gain the trust of the victims the hackers have posted various links and graphics to renowned and popular sources. It is important to note that the site is not a legitimate one and it is not the official source for downloading or purchasing the software. There is a real risk of downloading an infected file that can install all sorts of viruses on the victim computers – from Trojans to ransomware.

The privacy policy posted on the site reveals how the data is being handled:

  • Information is being gathered in both “active” and “passive” ways – even just opening up the site starts to generate data for analysis.
  • Detailed information is gathered about every visitor: site usage information, customer & site feedback, newsletter registration and purchase tracking.
  • All cookies are tracked by the site owners.

The site creators have protected the domain information nd have remained anonymous, a practice that is usual with scammers. In addition they have provided an email address for support queries that is hosted on another site: [email protected]. We suspect that the site is part of a large hacker-controlled affiliate network. The pcbooster.biz browser hijacker is merely a part of the overall scheme.

It can be acquired by downloading add-ons from third-party repositories or sites that pose as legitimate download sources.
