The attempt are relate to Earth Wendigo , a threat agentive role who does not seem to be ordinate with base whoop system , concord to an consultative from Trend Micro . Earth Wendigo has set on numerous formation , include politics bureau , pedantic meat , and university in Taiwan , get in May 2019 , Trend Micro pronounce . The lash out admit the consumption of shaft - phishing netmail to legion target area , admit Tibet , the Uyghur part , or Hong Kong - touch political leader and activist .
