Fast16: Pre-Stuxnet State Malware Reverse-Engineered
What Happened
Fast16 spread automatically across networks and manipulated calculation outputs in scientific software, likely targeting Iranian research operations. Reverse engineering reveals techniques and design philosophies that informed later operations including Stuxnet. The disclosure adds a new chapter to the public history of cyber-physical sabotage.
My Take
The interesting question isn't who built Fast16 — it's what 2026's equivalent looks like with AI assistance. Imagine malware that tampers with the outputs of your AI-driven financial models, supply-chain optimizers, or drug-discovery pipelines, in ways that look like noise. The defensive answer is computational integrity logging at the result level, not just file-integrity monitoring. Almost no enterprise does this today. Whoever builds the "ledger of computed truth" for enterprise AI workloads will sell to every Fortune 500 within five years.
