Stuxnet
Stuxnet is a malicious cyber worm, possibly of US and Israeli origin, It targeted the Iranian nuclear facilities at Natanz to make it look like a number of accidents.
Stuxnet specifically targets programmable logic controllers (PLCs), which allow the automation of electromechanical processes e.g.control machinery on factory assembly lines, or centrifuges for separating nuclear material.
Exploiting four zero-day flaws, Stuxnet functions by targeting machines using the Microsoft Windows operating system and networks, then seeking out Siemens Step7 software. Stuxnet compromised Iranian PLCs, collecting information on industrial systems and causing the centrifuges to be destroyed.
Stuxnet’s design and architecture are not domain-specific and it could be tailored as a platform for attacking modern SCADA and PLC systems (e.g., in automobile or power plants), the majority of which reside in Europe, Japan and the US.Stuxnet reportedly ruined almost one-fifth of Iran's nuclear centrifuges.
Operation Olympic Games
Operation Olympic Games was a covert and campaign of sabotage by means of cyber disruption, directed at Iranian nuclear facilities by the United States and maybe also by Israel.
Nitro Zeus
Nitro Zeus provided the NSA (National Security Agency) the ability to attack Iran’s command-and-control systems, which would obstruct the whole country’s communication capabilities.
The state-sponsored cyber hack would also disable Iranian air defenses, and harm financial systems as well as vital components of the power grid. This would allow US and Israeli aircraft to survey the area without being shot down.
The operation was in place as a second option just in case diplomacy and negotiations did not go smoothly. The cyber program was never actually used.
