APT37 (Reaper): The Overlooked North Korean ActorOn Feb. 2, 2018, we published a href="https://www.fireeye.com/blog/threat-research/2018/02/attacks-leveraging-adobe-zero-day.html">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 href="https://cdn.securelist.com/files/2017/10/Guerrero-Saade-Raiu-VB2017.pdf"

target="_blank">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.
