The operation from Bangladesh focused on compromising accounts across platforms and coordinating reporting to get targeted accounts and pages removed from Facebook, whereas the operation from Vietnam focused primarily on spreading malware to its targets.
The Bangladesh-based group targeted local activists, journalists and religious minorities, including those living abroad, to compromise their accounts and have some of them disabled by Facebook for violating its “community standards”.
