It is the season of malware attacks. After Ransomware attack and Judy malware caused a chaos in the digital world, computers across the globe have been infected by another deadly malware that is targeting web browsers and turning them into zombies (literally!). ‘Firewall’ malware has infected nearly 250 million computers worldwide, 20 percent of which include corporate networks. Data security firm Check Point was the first one to discover the threat and according to its analysis, India and Brazil are the two top affected countries in the world.

Here’s what you should know about the Fireball malware:

What is Fireball malware and how does it infect the computers?

Fireball malware works in two ways– it can run any code or program on the infected computer and it can manipulate the users’ web traffic to generate revenue for its attackers. It manipulates the infected systems’ web browsers to turn their default homepages into fake search engines, which in turn direct the user queries to Yahoo and Google.

The Fireball malware can not only download files, spy on the victims and run malicious codes on the infected systems but also steal private credentials and turn the infected computer into a malware downloading machine. What makes this malware more dangerous is the fact that once infected, it’s difficult to identify and even more difficult to remove it.
