Vexday analysis

Alinhado à Coreia do Norte e ativo desde 2023, o Contagious Interview (também rastreado como DeceptiveDevelopment, Gwisin Gang, Tenacious Pungsan, DEV#POPPER, PurpleBravo e TAG-121) conduz operações tanto de ciberespionagem quanto com motivação financeira, incluindo o roubo de criptomoedas e credenciais de usuários. O grupo tem como alvo sistemas Windows, Linux e macOS, com foco particular em indivíduos que atuam no desenvolvimento de software e em atividades relacionadas a criptomoedas. Ao grupo são atribuídas 54 técnicas documentadas no MITRE ATT&CK, sob o identificador G1052.

Attack chain

Plausible scenario built from the group's real techniques, ordered by the phases of an attack. Each step shows how the group typically operates.

Arsenal severity60

Impact: High

Illustrative chain derived from techniques documented in MITRE ATT&CK — it does not represent a specific past attack. Severity summarizes the known arsenal (kill-chain coverage, actively exploited CVEs, techniques).
