As corporations tried to adapt to remote working practices and other environmental changes, cybercriminals ramped up their attacks

Emotet is one of the largest malware campaign infrastructures. It started by initially targeting finance but soon after transformed to malware as a service for cybercriminals, opening a path for other attacks from TrickBot to Ryuk ransomware.

Figure 4 shows that the Emotet campaign threat activity increased by more than 5 times in 2020.
