Discovered in 2010, Stuxnet exploited several critical vulnerabilities in Windows which until then were unknown, including one guaranteeing its execution when inserting an infected USB key into the target system – even if a system's autorun capabilities were disabled, says FortiGuard Labs' Lovet.
From the infected system, Stuxnet was then able to spread into an internal network, until it reached its target: an industrial control system manufacturered by Siemens. In this particular instance, Stuxnet knew the weak point with a specific controller – and most likely intended to destroy or neutralize the industrial system.
