Fireball (software)
Malware has the ability of running any code on victim computers, such as downloading an arbitrary file and hijacking and manipulating infected user's web traffic in order to generate advertisement revenue. It installs plugins and additional configurations to boost its advertisements, and has potential to turn into a distributor for any additional malware. Malware is spread mostly via bundling. It is installed on a victim's machine alongside a wanted program, often without the user’s consent. Digital marketing agency Rafotech has been indicated as producer of the software. The same company has been accused to host fake search engines, which redirect the queries to yahoo.com or google.com. The fake search engines include tracking pixels used to collect private information from users. Fireball manipulates the infected browsers and turn their default search engines and home pages into the above mentioned fake search engines, which enable the software to spy on users of the infected browsers.
Linux malware
The following is a partial list of known Linux malware. However, few if any are in the wild, and most have been rendered obsolete by Linux updates or were never a threat. Known malware is not the only or even the most important threat: new malware or attacks directed to specific sites can use vulnerabilities previously unknown to the community or unused by malware.
