Zero Days

Zero Days (2016) is a documentary you can watch online on iFILM, directed by Alex Gibney — the same filmmaker behind Taxi to the Dark Side and Going Clear. Here he turns his lens on Stuxnet, a self-replicating computer worm that quietly destroyed uranium-enrichment centrifuges at Iran's Natanz facility before anyone publicly admitted it existed.

Gibney tracked down the people who actually know what happened: Symantec analysts who reverse-engineered the code, intelligence insiders who speak on camera only in silhouette, and former officials from the US and Israel who confirm nothing while hinting at everything. The tagline is "World War 3.0" and that's not hyperbole — the film argues this was the first state-sponsored cyberweapon deployed in peacetime, and that its uncontrolled spread set a precedent every adversary has since followed.

What makes it unsettling isn't the technical detail — it's how ordinary the decision-making looks. Stream Zero Days (2016) online on iFILM.
