Researchers Warn of EtterSilent Facilitating Risky Malware Delivery
Cybercriminals are using a new malicious document builder dubbed “EtterSilent,” according to researchers at Intel 471. The builder is used to craft Microsoft Office documents with macros that install malware. Intel 471 says EtterSilent has been used by many well-known malware strains, including Trickbot, Bazar, BokBot, Gozi ISFB, and QBot. The latter three campaigns rely on bulletproof hosting, making them resilient to takedowns.
