VERY IMPORTANT

In a previous blog post NTT Japan's Hiroki Hada introduced Tmanger, a new malware used by TA428. NTT Japan has identified a variant of Tmanger that they have labeled Smanager. Unlike Tmanger, Smanager is often found in Vietnam and may have been used in attacks on Vietnam-related organizations. Although Smanager is potentially a variant of Tmanger NTT Japan was unable to directly link Smanager to TA428.
