Threats:

MassLogger is a credential stealer and keylogger first identified in April 2020. It has been actively used in cyber campaigns to exfiltrate sensitive information from compromised systems. It is designed for easy use by less tech-savvy actors and is prominent for the capability of spreading via USB drives. It targets both individuals and organizations in various industries, mostly in Europe and the USA.
