Title: Details of new Mozart malware family unveiled
Description: A new malware family known as “Mozart” uses DNS to communicate with a command and control seemingly belonging to its creators. It also evades detection by disguising itself and executing specialized JSScript files. Once infected, Mozart can download other types of malware onto the victim machine, including ransomware and cryptocurrency miners. This malware is typically spread through spam campaigns with malicious PDF attachments. If a victim opens the PDF, it displays a message saying that the PDF reader doesn’t support a specific font, and asks the user to download a font, which actually points to a malicious ZIP file.
