In 2021, Trend Micro researchers observed several targeted attacks against researchers of academic organizations and think tanks in Japan. Trend Micro have since been tracking this series of attacks and identified the new intrusion set we have named “Earth Yako”. Their research points the attribution to the known campaign “Operation RestyLink” or “Enelink”.
Upon investigating several incidents, Trend Micro identified previously unknown malware, tactics, techniques and procedures (TTPs), and infrastructure used by Earth Yako for cyberespionage.
