Great documentary. Very informative and enlightening (not for the Pixar crowd). Very honest and surprisingly propaganda-free. The film maker went to great lengths to find credible, knowledgeable and highly qualified people to interview for this topic. Kudos."To make a documentary on such a complicated, far-reaching subject and maintain a common-sense perspective requires formidable organizational skills and a steady narrative hand to keep the movie from straying into any number of theoretical byways. It takes the imagination of a science- fiction writer to make it coherent and entertaining enough to hold your attention. Mr. Gibney has demonstrated all of these qualities..." Stephen Holden, The New York Times.

Zero Days is an important documentary devoted much needed attention to the issue of cyberwarfare, focusing on a case study of the Stuxnet attack. It provides a behind the scenes take on the discovery and the development of the virus, as well as the political developments that caused it to spiral out of control.Alex Gibney does a good job of explaining the technical aspects of the computer virus, as well as the political context that spurred the United States and Israel to develop the computer virus. He assembles a good cast of interviewees from various perspectives on the issue. Although Gibney has a definite viewpoint, he gives both sides of the question a hearing.Although I had previously watched news coverage dealing with Stuxnet, this documentary goes far more in depth, making good use of inside sources within the NSA. In particular, Gibney examines the split that emerged between the United States and Israel over the use of the virus, ultimately culminating in a near disaster. The film provides a disturbing warning of how the American and Israeli governments have potentially opened a Pandora's box.This film is important viewing that should be seen by everyone interested in current events or concerned over the implications of American foreign policy.

This film details Stuxnet as a phenomenon. It does a good job in deliberating about its ramifications and the situations that fomented it. Although the claims it makes cannot truly be verified, it does give you the general idea about the alleged attack. I would say there was a political angle to the telling of the tale, but the movie drives home the point that Stuxnet was the primer to the era of cyber warfare of this century. We get to see the dramatization of the 'predicament' of the Bush administration, the sepia tinted Ahmadinejad speeches (which should have been subtitled in English, but were not), and the fictional NSA agent who tells us the role Israel and the US supposedly played in the story. In the end it tries to give out a moral message that all war is bad, more weapons just mean more calamities waiting in the wings, and secrecy around a weapon is the first step to let it run amok.Overall, it was an informative and a slightly political documentary. Definitely worth a watch.

This two-hour documentary released Friday, July 8, and playing in selected theaters and streaming online, traces the history and consequences of Stuxnet, a sophisticated piece of malware unleashed on the world in 2010. Before you yawn and click away, there's an important feature of the Stuxnet worm and others like it that makes this story of vital interest to you. Stuxnet was not designed to invade your home or office computer, but to attack the industrial control systems that manage critical infrastructure. These systems make sure trains and airplanes don't crash, control car and truck traffic, maintain oil and gas production, manage industrial automation, ensure you have water to brush your teeth with and electricity to run the coffee maker, keep life-saving medical technology operating, and, of course, give you access to the internet. Cyber-attacks on these systems cause real-world, physical destruction, even widespread death. Behind the Computer Screen The Stuxnet story—still highly classified, but revealed over time—began with an effort by the United States and Israel to thwart Iran's ability to produce nuclear weapons by destroying centrifuges at the country's Natanz uranium enrichment facility. The software was diabolically clever, virtually undetectable, and essentially untraceable. In theory. The fact that it was a Zero Day exploit--that is, that the attack would begin before the software problem was discovered and attempts made to fix it or shut it down--and that the Stuxnet code contained not one, but four zero day features, was remarkable. Once it was inside, it worked autonomously; even the attacker could not call it back. The Israelis, apparently, were impatient. They assassinated Iranian nuclear scientists, and they changed the Stuxnet code, and it spread. It ended up infecting computers worldwide, at which point it was no longer secret, people were looking for it, and the Russians and others found it. "Israel blew the (malware's) cover and it could have led to war," the film says. Another consequence is that the day when something similar can be unleashed on us grows ever closer. It will come from one of three sources: • Cybercriminals, in it for the money • Activists, intent on making a political point or • Nation-states seeking intelligence or opportunities for sabotage. U.S. security agencies are not complacent. While they talk publicly about our cyber-defenses, in fact, there is a large (unexamined) effort to develop offensive cyber-weapons. There are reports of an even more draconian cyber-weapon embedded throughout Iranian institutions. Warding off its activation is believed a primary reason the Iranians finally struck a nuclear agreement. Certainly it prompted the rapid development surge in Iran's cyberarmy. In putting this story together, writer and director Alex Gibney interviewed former high-ranking U.S. and Israeli security officials, analysts from Symantec who teased the code apart, personnel from Russia's Kaspersky Lab, and many others, including CIA/NSA/DoD officials unable to speak on camera. "Fear Does Not Protect Us" The documentary makes a persuasive case for who holds the smoking Stuxnet gun, but it also suggests that finding fault is not the primary issue. The climate of international secrecy around Stuxnet—and the inevitable clones that will follow—makes an open discussion about them impossible. Nor does it allow development of rational strategies for managing the risks, regardless of how urgently needed those strategies are. Cyber-risk management will never be easy, but as one of the film's experts points out, "it will never happen unless you start." The subject is "hideously overclassified," says Michael Hayden, former director of both the NSA and CIA. (The climate of secrecy is so extreme that even the U.S. Department of Homeland Security cyber team was unaware that Stuxnet originated across town and spent countless resources trying to track it down.) We, of all nations, need this debate, because there is no more vulnerable country in the world, when it comes to systems' connectedness. "Evil and good live side by side," says an anonymous agent of the Israeli intelligence agency, Mossad. Keeping secrets is a good way to prevent being able to tell one from the other.
