The Emotet botnet has returned with updated payloads and a campaign that is hitting 100,000 targets per day. The botnet is one of the most prolific senders of malicious emails when it is active, but it regularly goes dormant for weeks or months at a time. The TrickBot malware is a well-known and sophisticated trojan first developed in 2016 as a banking malware. It has made a serious resurgence following an October takedown of the malware s infrastructure by Microsoft and others.
