On March 20, Korea’s National Intelligence Service (NIS) and Germany’s Federal Office for the Protection of the Constitution (Bundesamt für Verfassungsschutz, BfV) released a joint security advisory related to the Kimsuky hacker group. According to the joint security advisory, the Kimsuky hacker group exploited the extension feature of Chromium browsers and the app developer support feature for Android in an attack campaign to steal account credentials. Although their primary targets are Korean Peninsula and North Korea experts, it was stated that it could expand to unspecified individuals around the world.
