On 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"
