A South Korean forum focused on North Korea issues has suffered a data breach, according to the event’s organizers, potentially exposing many in the DPRK watcher community to follow-up attacks.

The Korea Global Forum for Peace (KGFP), hosted by South Korea’s unification ministry from Aug. 30 to Sept. 1, admitted to the breach late Saturday, saying that a high-level email account was compromised and that the names, affiliations and contact information of event participants were leaked.
