It first appears in the form of an advertisement, one that says "make money working from home" or "a virus has been detected". Subsequently, if the victim falls into the hacker trap and clicks on the banner, he is directed to a web page that prompts the user to open another website. As a last step, the malware asks the victim to press "Accept". And this is where Submelius enters its most important phase: the malware, in fact, ends up installing a malicious extension on Chrome.
