MirrorFace, a Chinese state-sponsored threat actor, has shifted its tactics to engage in spear phishing attacks targeting individuals in Japan.
The group is particularly interested in Japan's national security and international relations, focusing on topics related to China-US relations.
The spear phishing emails contain lures in the form of fake documents discussing Japan's economic security from the perspective of current US-China relations.
Victims who fell for the attack were infected with two backdoors, NOODPOOR and ANEL, with the latter being dormant and not observed in campaigns since 2018.
