Iran‑linked UNC1549 targets aerospace/defense via third‑party access and custom tools

Mandiant reports UNC1549 abused trusted relationships and VDI breakouts to breach high‑maturity targets, then used DLL search‑order hijacking and custom tooling (e.g., TWOSTROKE, LIGHTRAIL) for persistence, tunneling, and DCSync‑style credential theft. Defenders should harden vendor access paths, monitor for Azure Web Apps C2, detect abnormal DC password resets and DCSync events, and restrict RDP/PowerShell remoting.
