Gelsemium  (Back to overview)

aka: 狼毒草

The Gelsemium group has been active since at least 2014 and was described in the past by a few security companies. Gelsemium’s name comes from one possible translation ESET found while reading a report from VenusTech who dubbed the group 狼毒草 for the first time. It’s the name of a genus of flowering plants belonging to the family Gelsemiaceae, Gelsemium elegans is the species that contains toxic compounds like Gelsemine, Gelsenicine and Gelsevirine, which ESET choses as names for the three components of this malware family.
