[Contagious Interview](https://attack.mitre.org/groups/G1052) is a North Korea–aligned threat group active since 2023. The group conducts both cyberespionage and financially motivated operations, including the theft of cryptocurrency and user credentials. [Contagious Interview](https://attack.mitre.org/groups/G1052) targets Windows, Linux, and macOS systems, with a particular focus on individuals engaged in software development and cryptocurrency-related activities.
