After almost a three-week holiday vacation, the Emotet trojan is back and targeting the over eighty countries with malicious spam campaigns. The threat actors use various email templates that pretend to be invoices, reports, voice mails, holiday party invites, or even invites to a Greta Thunberg climate change demonstration. These emails include malicious attachments that when opened will install the emotet Trojan. Once installed, Emotett will use the victim’s computer to send further spam and will also download other infections such as TrickBot, which may ultimately lead to a Ryuk Ransomware infection.
