Before the world could fully recover from the WannaCry ransomware bug, another deadly malware dubbed as Fireball has emerged with the potential to make several million PCs across the globe vulnerable to hacking.
Online security watchdog Check Point, which is credited for discovering infamous Judy malware in Android devices, has found another malicious Fireball firmware affecting more than 250 million computers across the world and 20 percent of all the global corporate networks. Interestingly, India, which is fast expanding its digital footprint, is said to be the worst affected.
According to Check Point, over 250 million computers worldwide have been infected: specifically, 25.3 million infections in India (10.1 percent), 24.1 million in Brazil (9.6 percent), 16.1 million in Mexico (6.4 percent) and 13.1 million in Indonesia (5.2 percent). The United States has witnessed 5.5 million infections (2.2 percent).
Fireball is said to be created by Chinese ad corporation Rafotech to manipulate users' browsers on the computer to get false clicks and promotion for its clients online.
How does Fireball malware get into the PC?
Rafotech has reportedly partnered with some legitimate software firms and has managed to get the consent to load its Fireball malware mostly via bundling i.e. installed on victim machines alongside a wanted program but without the user's consent.
What Fireball malware does to the PC?
Rafotech uses Fireball to manipulate the victims' browsers and turn their default search engines and home pages into fake search engines. This redirects the queries to either yahoo.com or Google.com. The fake search engines include tracking pixels used to collect the users' private information and web-traffic to generate ad-revenue.
Should you be worried over Fireball malware?
Yes, users must be very wary of Fireball malware. Though, it is currently operating as browser hijackers to get false clicks and forcefully divert the user to its client's webpage. It has potential to turn into a full-functioning malware downloader and is capable of executing any code on the victim machines, resulting in a wide range of actions from stealing credentials to dropping additional malware. This creates a massive security flaw in targeted machines and networks, Check Point report said.
