NSHC’s February 2023 Korean ThreatRecon report says SectorA activity was the largest share of observed threat-actor operations during the period and highlights five SectorA clusters. The SectorA examples include activity in Sweden using company-evaluation archive lures to steal system information, Korean attacks using fake administrative security mail and HTML malware with MSHTA-based follow-on script execution, Word-document malware targeting broadcasting/telecommunications and research personnel, presentation-themed archives used against the United States, Canada, and Norway, and LNK malware disguised as explanatory-document requests. The report assesses SectorA groups as continuing long-term collection against Korean political, diplomatic, and government-related information while also pursuing financially motivated operations worldwide.
