However, this new discovery shows just how dangerous it can be to install files from the internet as they don’t always go through the same rigorous checks from official sources.
Speaking about the bug, Igor Golovin, security expert at Kaspersky, said: “With this app, it is hard for users to recognize the potential threat because the mod application actually does what is proposed – it adds additional features. However, we have observed how cybercriminals have started to spread malicious files through the ad blocks in such apps.
“That is why we recommend you only use messenger software downloaded from official app stores. They may lack some additional functions, but they will not install a bunch of malware on your smartphone.”
