Executive Summary APT45 is a long-running, moderately sophisticated North Korean cyber operator that has carried out espionage campaigns as early as 2009. APT45 has gradually expanded into financially-motivated operations, and the group\'s suspected development and deployment of ransomware sets it apart from other North Korean operators. APT45 and activity clusters suspected of being linked to the group are strongly associated with a distinct genealogy of malware families separate from peer North Korean operators like TEMP.Hermit and APT43. Among the groups assessed to operate from the Democratic People\'s Republic of Korea (DPRK), APT45 has been the most frequently observed targeting critical infrastructure. Overview Mandiant assesses with high confidence that APT45 is a moderately sophisticated cyber operator that supports the interests of the DPRK. Since at least 2009, APT45 has carried out a range of cyber operations aligned with the shifting geopolitical interests of the North Korean state. Although the group\'s earliest observed activities consisted of espionage campaigns against government agencies and defense industries, APT45 has expanded its remit to financially-motivated operations, including targeting of the financial vertical; we also assess with moderate confidence that APT45 has engaged in the development of ransomware. Additionally, while multiple DPRK-nexus groups focused on healthcare and pharmaceuticals during the initial stages of the COVID-19 pandemic, APT45 has continued to target this vertical longer than other groups, suggesting an ongoing mandate to collect related information. Separately, the group has conducted operations against nuclear-related entities, underscoring its role in supporting DPRK priorities. 
Shifts in Targeting and Expanding Operations
Similar to other cyber threat activity attributed to North Korea-nexus groups, shifts in APT45 operations have reflected the DPRK\'s changing priorities. Malware samples indicate the group was active as early as 2009, although an observed focus on government agencies and the defense industry was observed beginning in 2017. Identified activity in 2019 aligned with Pyongyang\'s continued interest in nuclear issues and energy. Although it is not clear if financially-motivated operations are a focus of APT45\'s current mandate, the group is distinct from other North Korean operators in its suspected interest in ransomware. Given available information, it is possible that APT45 is carrying out financially-motivated cybercrime not only in support of its own operations but to generate funds for other North Korean state priorities.

Le 2 février 2018, nous avons publié un Blog détaillant l'utilisation d'une vulnérabilité Adobe Flash Zero-Day (CVE-2018-4878) par un groupe de cyber-espionnage nord-coréen présumé que nous suivons maintenant comme APT37 (Reaper).
Notre analyse de l'activité récente d'APT37 \\ révèle que les opérations du groupe \\ se développent en portée et en sophistication, avec un ensemble d'outils qui comprend l'accès aux vulnérabilités zéro-jour et aux logiciels malveillants d'essuie-glace.Nous évaluons avec une grande confiance que cette activité est réalisée au nom du gouvernement nord-coréen compte tenu des artefacts de développement de logiciels malveillants et ciblant qui s'aligne sur l'État nord-coréen
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 |
