In the aftermath, the European judicial institutions threatened the social network with a fine of up to 50 million euros.

As if all this wasn't enough, it was recently discovered a malicious program that invited itself into the features of the messaging application. This is the work of ESET's cybersecurity specialists. This malware, according to researchers at the cybersecurity company, is a real danger to be taken very seriously: "This malware spreads via the victim's WhatsApp application by automatically responding to all WhatsApp notifications with a link to a malicious version of Huawei Mobile," explains computer security researcher Luca Stefanko.
