ESET researchers have discovered a new, sneaky malware called Joao, which spreads through computer games posted on invalid websites. Joao is a modular malware capable of downloading and executing other malicious code.
“To spread the malicious software Joao, its creators have abused the massively multiplayer role-playing online games. They modified them so they can download even more malicious programs”,
explains Tomáš Gardoň, Malware Analyst at ESET.
ESET’s research has shown that creators of the malware campaign abused several game titles from Aeria Games, publishing their modified versions on various inappropriate websites. One of these has managed to remain active in spreading malicious software, gf.ignitgames[.]to, but ESET’s security solutions have been able to block it.
Games that contained Joao could gather information about the invated computer and then download additional items sent by the C & C server. ESET researchers found during the investigation that Joao had the potential for backdoor, spy and DDoS attacks.
“The infection process is well “disguised” to fool the victims and these modified toys work according to the design of their creators. Once the player has been fooled and downloaded the modified game, there is no evidence to suspect him. Those who are not protected by a reliable security solution simply end up with infected computers”,
Also, ESET experts have gathered a series of tips to help gamers enjoy their game without the risk of threats, some of which are:
- Prefer official sources wherever possible.
- Make sure games have the latest updates.
- Use a reliable security solution and turn it on as long as you play.
- Keep in mind that there are other threats that you need to protect yourself.
