Also known asMealybug

Mealybug is a threat group that researchers have linked to Emotet. The provided content states that Mealybug has been on the security community's radar since 2014. In this context, Emotet is described as first surfacing in 2014 as banking malware targeting credential theft, later evolving into a broader threat-delivery service used to distribute additional malware. The content notes that Emotet was observed in early 2018 using its loader functionality to spread Quakbot and ransomware variants, and that related detection guidance includes monitoring rarely used executables, suspicious registry persistence paths, and cmd.exe launching script interpreters as indicators of compromise. No additional high-confidence aliases, sub-groups, attribution, or nation-state affiliation are provided in the content beyond the alias/name Mealybug.
