Zero Days is a 2016 documentary film created by award winning film director Alex Gibney (The Armstrong Lie,Taxi to the Dark Side, Going Clear: Scientology and the Prison of Belief) about the famous self-replicating virus Stuxnet. Stuxnet is a computer virus which was first detected back in 2012 when it was found in the control systems of Iranian nuclear facilities, the source of the malicious computer program can not be determined however there has been indications of joint US/Israeli involvement due to the perceived agenda of the Virus. The virus disrupted the Iranian nuclear program and many other services by rendering some facilities useless which is exactly what the US wanted and is the reason for the speculation of their involvement in the viruses development and deployment, however this is totally speculation; there is no solid evidence to backup these claims.
The title of the documentary “Zero Days” comes from the hacking terminology “Zero Day” which is when a system breach is discovered for the first time. Stuxnet was a particularly brutal hack which targets programmable logic controllers, the scope of which means is can target almost anything that is automatically controlled by computers such as automated production lines.
