The subject of Alex Gibney’s latest documentary is as fascinating as it is concerning. Zero Days examines the use of Stuxnet, a computer virus that was discovered in 2010 by IT experts; it was apparently created by the US and Israeli governments with the intention of sabotaging Iran’s nuclear programme, but it spread uncontrollably, as such malware is wont to do. Gibney and many of the talking heads here – including senior NSA figures and even a computer-generated face that lends the doc a bizarre twist – suggest that Stuxnet heralds the start of a new phase of international cyberwarfare, with Iran setting up its own cyberarmy as a result of the attack, and one can only wonder about the effects or the potential devastation that will result from attacks to various online infrastructures in the future. In short… we’re all fucked. (****)
