APT32 nation-state hackers were linked to Vietnamese IT firm CyberOne Group in a report published earlier today. Facebook added all associated domains with the two entities to a global block list to prevent them from being shared on the social network. Facebook also removed all accounts associated with the group from its platform and notified the individuals that may have been targeted by APT 32. The group has been behind attacks against foreign government, multi-national corporations, journalists, and Chinese maritime construction firms since at least 2014.
