Playful Taurus, also known as APT15, BackdoorDiplomacy, Vixen Panda, KeChang and NICKEL, is a Chinese advanced persistent threat group that routinely conducts cyber espionage campaigns. The group has been active since at least 2010 and has historically targeted government and diplomatic entities across North and South America, Africa and the Middle East.
In June 2021, ESET reported that this group had upgraded their tool kit to include a new backdoor called Turian. This backdoor remains under active development and we assess that it is used exclusively by Playful Taurus actors.
