Substantial-profile government entities in Southeast Asia are the target of a cyber espionage marketing campaign carried out by a Chinese risk actor regarded as Sharp Panda given that late final calendar year.
The intrusions are characterized by the use of a new variation of the Soul modular framework, marking a departure from the group’s attack chains observed in 2021.
