HC3 Threat Briefing TLP White: Dridex Malware Report, June 25, 2020

Dridex was originally developed as a financial Trojan that initially makes contact with its victims via
phishing/spam email campaigns. 
Dridex is one of the most prevalent malwares in use today. While Dridex has historically been used in attacks on the financial sector, researchers have determined that the developers of Dridex were also behind the development of Locky and BitPaymer ransomware, which have affected much of the Healthcare and Public Health (HPH) sector.
