Fast16 Malware

Source: Schneier on Security

Overview

Researchers have reverse‑engineered a piece of malware named Fast16. It is almost certainly state‑sponsored, likely of US origin, and was deployed against Iran years before Stuxnet.

“The Fast16 malware was designed to carry out the most subtle form of sabotage ever seen in an in‑the‑wild malware tool: by automatically spreading across networks and then silently manipulating computation processes in certain software applications that perform high‑precision mathematical calculations and simulate physical phenomena, Fast16 can alter the results of those programs to cause failures that range from faulty research results to catastrophic damage to real‑world equipment.”
