We attribute this activity to a threat activity group tracked as RedGolf, which is highly likely to be a Chinese state-sponsored group. RedGolf closely overlaps with threat activity reported in open sources under the aliases APT41/BARIUM and has likely carried out state-sponsored espionage activity in parallel with financially motivated operations for personal gain from at least 2014 onward.",
