Emotet is a malware strain and a cybercrime operation believed to be based in Ukraine. The malware, also known as Heodo, was first detected in 2014 and deemed one of the most prevalent threats of the decade. In 2021, the servers used for Emotet were disrupted through global police action in Germany and Ukraine and brought under the control of law enforcement. Despite this disruption, Emotet resurfaced in subsequent years with new capabilities, continuing to be regarded as one of the Internet’s most persistent and adaptable threats.

First versions of the Emotet malware functioned as a banking trojan aimed at stealing banking credentials from infected hosts. Throughout 2016 and 2017, Emotet operators, sometimes known as Mealybug, updated the trojan and reconfigured it to work primarily as a "loader," a type of malware that gains access to a system, and then allows its operators to download additional payloads. Second-stage payloads can be any type of executable code, from Emotet's own modules to malware developed by other cybercrime gangs.
