Predecessor of Stuxnet: fast16 sabotaged nuclear-test simulations

Colleagues, note a cybersecurity discovery: pre-Stuxnet malware fast16 undermined nuclear-test simulations.

- Symantec/Carbon Black: fast16 (Lua) altered calculations in LS‑DYNA and AUTODYN, distorting detonation models.
- Triggers on density (>30 g/cm³) — consistent with implosion device profiles.
- Spread over networks and avoided machines with specific security products; behavior indicates a targeted, long-running operation.

Why it matters: confirms state-aligned industrial sabotage predating Stuxnet and underscores the need to harden engineering software.

How do you assess the risk of similar targeted attacks today?
