Fast16: Early Sabotage Malware Targeted Nuclear-Weapon Simulations
Security researchers uncovered Fast16, a pre‑Stuxnet sabotage framework dating to circa 2005 that targets LS-DYNA and AUTODYN high‑explosive simulations to tamper uranium compression models, using a kernel driver, Lua engine, and 101 hook rules across multiple software builds; it activates under specific high‑explosive scenarios and density thresholds (30 g/cm3), persists via Windows registry tricks, and spreads by enumerating network shares and impersonating users, indicating a sustained campaign to disrupt nuclear weapon simulations. Defenses include strict application control, blocking unsigned or unfamiliar drivers, and robust endpoint protection to prevent dual‑use tooling.
