Fireball malware infected 250 million computers worldwide

Check Point researchers discovered a high volume Chinese threat operation which has infected over 250 million computers worldwide. The installed malware, named Fireball, takes over target web browsers, turning them into zombies.

Fireball has two main functionalities: one is the ability to run any code on victims’ computers and downloading any file or malware; the other is hijacking and manipulating infected users’ web-traffic to generate ad-revenue. Currently, Fireball installs plug-ins and additional configurations to boost its advertisements, but just as easily it can turn into a prominent distributor for any additional malware.

According to Check Point, this operation is run by Rafotech, a large digital marketing agency based in Beijing. Rafotech uses Fireball to manipulate the victims’ browsers and turn their default search engines and home-pages into fake search engines which simply redirect the queries to either or

The fake search engines include tracking pixels used to collect the users’ private information. Fireball can also spy on victims, perform efficient malware dropping, and execute any malicious code in the infected machines, thus creating a massive security flaw in targeted machines and networks.
