2025 Emerging Threat Vectors

AI-Facilitated Trafficking

Emerging technology enabling illicit access and material sourcing at scale. LLM-assisted procurement chains have appeared in interdicted trafficking cases in 2024 and 2025.

Airspace Breaches

Drone incursions over restricted nuclear facilities are increasing in frequency across Europe, North America, and Asia. Multiple 2024 incidents remain officially unattributed.

Cyberattacks on Nuclear Infrastructure

Sophistication and frequency rising year on year. State and non-state actors both active. Not all detected. Not all disclosed.

Unauthorized Possession

Continued proliferation of sealed sources, industrial radioactive material, and legacy Soviet-era stock with no sign of deceleration into 2025.

Weapons-Grade Material Events

Highly Enriched Uranium (HEU): 4 Confirmed
