Researchers at FireEye say a newly profiled group they nicknamed APT 37 or Reaper is now targeting Japan, Vietnam and the Middle East, including targets in a bevy of industries. It had until recently been focused on South Korea. FireEye believes Reaper is North Korean.
Between the lines: North Korea runs several separate hacking operations, including the prominent (and distinct) Lazarus Group known for hacking Sony. Reaper is known to have used a previously undiscovered security flaw in Flash during an attack. Since such unknown security problems are not cheap to research, this suggests the group is fairly well resourced.
