APT39

Also known asChafer · Remix Kitten · ITG07 · COBALT HICKMAN · TA454 · Radio Serpens · Burgundy Sandstorm

Summary

MOIS cyber-espionage activity conducted through the front company Rana Intelligence Computing (MITRE; US Treasury). Mandiant assesses that its key mission is to track or monitor targets of interest, collect personal information, including travel itineraries, and gather customer data from telecommunications firms; Treasury says the campaign targeted Iranian dissidents, journalists and international companies in the travel sector. On 17 September 2020 OFAC sanctioned APT39, 45 associated individuals and one front company (Rana) under E.O. 13553, and the concurrent FBI advisory detailed eight separate and distinct sets of Rana malware. Bitdefender (2020) documented intrusions against air-transportation and government victims in Kuwait and Saudi Arabia.
