The Department of Homeland Security's CISA (Cybersecurity and Infrastructure Security Agency) has issued a warning of increased activity around highly targeted Emotet attacks. Emotet's main threat is that it can act as a carrier (or "dropper") for a wide variety of different malware payloads.
Emotet is classified as a banking Trojan that spreads primarily through email attachments. It is known for its ability to quickly and widely spread through an organization once an initial infection occurs. According to the DHS, Emotet is "…among the most costly and destructive malware affecting state, local, tribal, and territorial (SLTT) governments, and the private and public sectors."
