APT37 (Reaper): The Overlooked North Korean Actor

On Feb. 2, 2018, we published a blog
detailing the use of an Adobe Flash zero-day
vulnerability (CVE-2018-4878) by a suspected North Korean cyber
espionage group that we now track as APT37 (Reaper).

Our analysis of APT37’s recent activity reveals that the group’s
operations are expanding in scope and sophistication, with a toolset
that includes access to zero-day vulnerabilities and wiper malware. We
assess with high confidence that this activity is carried out on
behalf of the North Korean government given malware development
artifacts and targeting that aligns with North Korean state interests.
FireEye iSIGHT Intelligence believes that APT37 is aligned with the
activity publicly reported as Scarcruft
and Group123.

Read our report,
APT37
(Reaper): The Overlooked North Korean Actor, to learn more
about our assessment that this threat actor is working on behalf of
the North Korean government, as well as various other details about
their operations:

• Targeting: Primarily South Korea – though also Japan, Vietnam
  and the Middle East – in various industry verticals, including
  chemicals, electronics, manufacturing, aerospace, automotive, and
  healthcare.
• Initial Infection Tactics: Social engineering tactics
  tailored specifically to desired targets, strategic web compromises
  typical of targeted cyber espionage operations, and the use of
  torrent file-sharing sites to distribute malware more
  indiscriminately.
• Exploited Vulnerabilities: Frequent exploitation of
  vulnerabilities in Hangul Word Processor (HWP), as well as Adobe
  Flash. The group has demonstrated access to zero-day vulnerabilities
  (CVE-2018-0802), and the ability to incorporate them into
  operations.
• Command and Control Infrastructure: Compromised servers,
  messaging platforms, and cloud service providers to avoid detection.
  The group has shown increasing sophistication by improving their
  operational security over time.
• Malware: A diverse suite of malware for initial intrusion and
  exfiltration. Along with custom malware used for espionage purposes,
  APT37 also has access to destructive malware.
