Zero Days

Saw this at the Berlinale 2016, where it was programmed as part of the official Competition section. I have to start with a full disclaimer, by confessing that information security has been my full time occupation for at least 25 years. As such it was not my intention to learn something new when viewing this documentary about the infamous Stuxnet worm, jointly developed by Israel and US, targeting Iranian reactors and obstructing the production of nuclear material. Yet I'm very interested in each and every vehicle (movie, book, newspaper article, whatever) to make non-IT people aware of the issues at hand, if only to provide material for an open debate about the pros and cons of "cyber warfare" with much wider implications than the average layman realizes.

As observed with previous movies about IT-related issues (WikiLeaks, Snowden, Steve Jobs etcetera) it is very difficult to sit it through while being (like myself) someone who worked in IT all his life. We saw numerous fragments of Assembler, flashing lights from network equipment, heavily populated cable bundles, and many screens showing various sorts of abracadabra, all supposedly intending to look technical for an average layman. Another problem is that several talking heads ducked when asked specific questions about Stuxnet, the latter being the main topic of this movie. Most of them had the usual excuse *Even when I knew about it, I cannot elaborate". Luckily, we heard not once the excuse "I can tell you about it but after that I have to shoot you", usually intended as a humorous escape from hot questions without appearing offensive or overly defiant. Several high ranking officials only wanted to speak out in general terms, thereby avoiding Stuxnet and other concrete projects, by explaining what they found wrong, especially about the secrecy that most found exaggerated and unnecessary. As such, their contributions were still useful, albeit not exactly touching the subject at hand.

Nevertheless, I heard a few new things I had not thought about yet. Firstly, Stuxnet was not designed to become so visible as it did. People at the NSA were furious when seeing that Israel extended v1.1 of the software to be more aggressive, making it spread and allowing it to surface, while that never had been the intention. The net result is that other countries may find justification to counter with similar software, now the US has provided for a precedent. Secondly, many people in CIA and NSA express their concerns about over-classification, preventing an open debate on future policies and rules of engagement in cyber space, like similar rules developed in the past for army, navy and air force. Cyber weapons are the fourth category, and it may take 20 to 30 years to create clear rules and policies for it. Lastly, the net effect that Stuxnet had on Iranian nuclear program, has proved to be negligible in the long run. There was a noticeable dip in the production statistics, but it triggered Iran to invest extra in centrifuges. An extra side effect was that Iran invested in cyber powers of their own, by attracting talented people on this field of expertise. As of now, it looks like they succeeded in overpowering the western world in this so-called cyber war. In other words, due to Stuxnet we lost our head start, and it is doubtful we will ever regain that.

There was one talking head with distorted voice and face, who appeared many times throughout the story. In hindsight, she was reading collected texts from several people working in NSA, CIA etcetera, all of them having useful insights on the matter but unable to come forward. Being reasonably versed in these issues, I am of the opinion that these texts sound genuine and seem to really come from people with intimate knowledge, which would otherwise be kept from the public. One example is that they internally made fun about "air gapped", the common defense against infections from the outside. They knew several ways to get over this obstacle, e.g. by infecting vendors responsible for installing and updating software in the plant, more or less working like so-called watering hole attacks. Reading these texts as done here, was an artificial but necessary addition to the documentary. In a final scene the one reading the texts revealed herself as an actress who had no personal involvement in the issues, but was effectively used as a vehicle to get this information across. During the press conference organized by the Berlinale it was explained that this was the only way to obtain and release this information, if only to protect the sources since harsh policies have been issued to deal with information leakage.

All in all, I'm not sure the message will land where it should land, namely with non-IT people who should know about the implications of "cyber warfare", having an impact on our future that cannot be underestimated. I don't think that a documentary that takes nearly 2 hours, will achieve said goal. Nevertheless, I applaud every honest attempt. The documentary is well made and tries to present a balanced view on the matter. Well made, but probably shooting over everyone's head and defeating its well-intended purposes.

"Zero Days" conveys two messages. The broader one, though hardly new, bears repeating and applies as much to advances in medical science as to war. In a hypercompetitive world, it asks, when do we decide not to pursue innovation and hold back for the greater good? Has technology outrun our capacity to control it?

This was one of the most enlightening documentaries I've seen in recent years; it was also one of the most disturbing films I've seen in a long time. I had no idea how far into the age of cyberwarfare we already are, and how serious the consequences of this kind of conflict already can be. If you're a conspiracy theorist or otherwise prone to paranoia, don't watch this - but if you want to learn some of the darker secrets most government agencies try to shield our fragile little minds from, and if you want to know some hard truths about what's possible and what's already happening in terms of cyberattacks, I highly recommend this excellent documentary. 9 stars out of 10.

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.

The new weapons of warfare (specifically computer viruses) and the climate of secrecy and legality, in which such weapons are used are excellently portrayed in this documentary. Experts of high standing from both the intelligence and cyber security communities have been interviewed and their insights and opinions wonderfully woven together to tell the story of the most complex stealth- like computer virus to have targeted very specific critical infrastructure to date, aka 'The Stuxnet' virus This documentary covers new ground in documentary film making and uses the Stuxnet virus as a platform to explain many of the complexities, secrecy and politics involved with international cyber warfare and the dangers and to some extent morality of it. Essential informative viewing without doubt!
