A subgroup of {{APT 41}}. (Trend Micro) Earth Freybug is a cyberthreat group that has been active since at least 2012 that focuses on espionage and financially motivated activities. It has been observed to target organizations from various sectors across different countries. Earth Freybug actors use a diverse range of tools and techniques, including LOLBins and custom malware.
