BSharmaat April 28,2017 This video provides good overview of the Stuxnet Virus, malware, Trojan, etc whatever malicious word defines the many forms this 500KB code. Lots of theories have abounded to it origination. To get a broader view of what Stuxnet is, one needs to watch the documentary Zero Days. Alex Gibney's new documentary, Zero Days. This documents the development a cyber weapon jointly developed by the U.S. and Israel. According to the documentary, the CIA and Mossad, Unit 8200 specifically, developed this code.
Due to internal pressure, the unit modified the code to be more aggressive, and "that caused two things to happen. One, it's spread all over the world because in order to spread into Natanz, the idea was that it would just spread rapaciously, and then various IT firms - they would take their, you know, thumb drives or whatever into the Natanz plant it would get in. But it was also spreading out." [http://www.npr.org/2016/07/04/484713086/documentary-explores-the-cyber-war-secrets-of-stuxnet]
tritran42at April 30,2017 This video talks about the Stuxnet, which is very impressive virus. There are four distinct faces that Stuxnet goes to. First, it is got to spread on its own. It discovers the proper computers. It can disrupt the centrifuges and all while evading detection. The Stuxnet uses seven distinct mechanisms to spread to new computer. After that it is patient stay in the system to measure frequency converters for 13 days. After that Stuxnet raises the spin rate to 1410Hz for 15 minutes then sleeps for 27 days. It repeats this process over and over. Stuxnet can avoid detection security products because of its different behaviors. Moreover, Stuxnet fakes itself look like it comes from a real tech corporation. Stuxnet destroyed about 1000 Iranian centrifuges. As the speaker in the video mentions Stuxnet is not using any new technology. However, the author of Stuxnet knows how mount the right piece of each technology together that makes Stuxnet becomes something new. That is what we do not expect from the cybercrime because we cannot think like the cybercrime.
sreinoso103at May 04,2017 Really great explanations of something I personally hadn't heard of before. Incredible genius at play to create such a software. Makes you curious how long and how many people it took to craft Stuxnet. With insider information and a "wiz kid" can this level of virus be created overnight, or did it take thousands of hours and testing to get a functioning program. Instills both fear and hope as this could be used to shut down evil or good depending on who's interests are being pushed.
Wangjaat May 10,2017 Stuxnet's creators surely had a huge budget to create the software. It being the first known, also gave them plenty of time to develop it. Now that cyberwarfare has begun, governments no longer have an infinite amount of time to develop their weapons. Governments, slow to change, will have difficulty keeping up, as security holes dry up. Topping Stuxnet will be an improbable task.
tmoore35at June 10,2017 This is why DoD and OGAs undergo insider threat training, cyber awareness training, and the use of digital media was restricted. Iran likely had safeguards as well, but the intelligence assets were almost certainly insiders in order to gather the information needed to develop Stuxnet's parameters and to tailor its spreading mechanisms and attack methodology. As stated in the video, this was a feat of espionage, not just engineering.
Wangja, you mention that topping Stuxnet would be an improbable task. I would not be surprised to learn that it had already been topped. Given the proper resources and assets I believe similar tools could already developed and ready for deployment. Hackers and State actors are limited only by imagination and resources.
At the end of the video he mentions his biggest fear being the infection of several million computers for nefarious purposes. While not quite to that level, firmware exploits on DVRs and other devices were used to shutdown internet access to heavily populated regions of the United States: imagination and resources.
