Suite of sophisticated nation-state attack tools linked to Stuxnet — Equation Group

Kaspersky researchers discovered an extensive toolset on customer computers that they named EquationLaser, EquationDrug and GrayFish and associated with attackers called the Equation Group. One worm, Fanny, used two of the same zero-day exploits used by Stuxnet. The researchers found no solid evidence that the tools were operated by the NSA and made no such attribution.
