DEF CON 23 - Sean Metcalfe - Red vs Blue: Modern Active Directory Attacks & Defense
 
50:25
Kerberos “Golden Tickets” were unveiled by Alva “Skip” Duckwall & Benjamin Delpy in 2014 during their Black Hat USA presentation. Around this time, Active Directory (AD) admins all over the world felt a great disturbance in the Force. Golden Tickets are the ultimate method for persistent, forever AD admin rights to a network since they are valid Kerberos tickets and can’t be detected, right? This talk explores the latest Active Directory attack vectors and describes how Golden Ticket usage can be detected. When forged Kerberos tickets are used in AD, there are some interesting artifacts that can be identified. Yes, despite what you may have read on the internet, there are ways to detect Golden & Silver Ticket usage. Skip the fluff and dive right into the technical detail describing the latest methods for gaining and maintaining administrative access in Active Directory, including some sneaky AD persistence methods. Also covered are traditional security measures that work (and ones that don’t) as well as the mitigation strategies that disrupts the attacker’s preferred game-plan. Prepare to go beyond “Pass-the-Hash” and down the rabbit hole. Some of the topics covered: Sneaky persistence methods attackers use to maintain admin rights. How attackers go from zero to (Domain) Admin MS14-068: the vulnerability, the exploit, and the danger. “SPN Scanning” with PowerShell to identify potential targets without network scans (SQL, Exchange, FIM, web servers, etc.). Exploiting weak service account passwords as a regular AD user. Mimikatz, the attacker’s multi-tool. Using Silver Tickets for stealthy persistence that won’t be detected (until now). Identifying forged Kerberos tickets (Golden & Silver Tickets) on your network. Detecting offensive PowerShell tools like Invoke-Mimikatz. Active Directory attack mitigation. Kerberos expertise is not required since the presentation covers how Active Directory leverages Kerberos for authentication identifying the areas useful for attack. Information presented is useful for both Red Team & Blue Team members. Speaker Bio: Sean Metcalfe is the Chief Technology Officer at Dan Solutions, a company that provides Microsoft platform engineering and security expertise. Mr. Metcalf is one of about 100 people in the world who holds the elite Microsoft Certified Master Directory Services (MCM) certification. Furthermore, he assisted Microsoft in developing the Microsoft Certified Master Directory Services certification program for Windows Server 2012. Mr. Metcalf has provided Active Directory and security expertise to government, corporate, and educational entities since Active Directory was released. He currently provides security consulting services to customers with large Active Directory environments and regularly posts useful Active Directory security information on his blog, ADSecurity.org.

Zittrain and Zuckerberg discuss encryption, ‘information fiduciaries’ and targeted advertisements
 
01:43:02
Should Facebook be considered an “information fiduciary” when it comes to the privacy of its clients? How should we weigh the pros and cons of encryption schemes which might bolster privacy and data security at the risk of shutting out law enforcement? And why shouldn’t Facebook tell users how much advertising revenue their respective data generates on a daily basis? Those were some of the questions Facebook Co-founder and CEO Mark Zuckerberg discussed with Jonathan Zittrain ’95, HLS’s George Bemis Professor of International Law, in a conversation among students at Harvard Law School on Feb. 11. The discussion was part of a series of study sessions for Harvard’s Techtopia initiative, a program for students across the University to explore problems in technology and governance, and it included participants from Zittrain’s course on Internet & Society: The Technologies and Politics of Control.

Z-Wave vs ZigBee vs WIFI - Choosing a Standard: Your Smart Home Questions Answered

Z-Wave vs ZigBee vs WIFI - Choosing a Standard: Your Smart Home Questions Answered As we spoke about in our video, here's our new Patreon site: https://www.patreon.com/automateyourlife - please join us there! Zigbee, Z-Wave, and Wifi all have their merits when we talk about smart home devices. As a result, it can be difficult to choose a (or multiple) standards for your smart home or home automation setup. You can cause yourself a lot of grief in the future with the wrong choices when you're first designing your smart home. You can also cause yourself a lot of grief in the future when you go out and buy the wrong devices. With Z-Wave, you get a 800-900 MHz carrier frequency, which means lower bandwidth than the other standards. With that carrier frequency comes very little interference from other devices, unless you own an older cordless phone (some were in the 900 MHz band). This lower frequency also means a longer distance than the other standards/protocols (up to 100 meters). The network is also a "mesh" network, which means the devices connect to each other. With Zigbee, you get a 2.4 GHz carrier frequency, which means a higher bandwidth than Z-Wave. With that carrier frequency comes the chance for interference from Wifi signals in your home. However, Wifi can now be 2.4 GHz or 5 GHz, so you can for the most part, eliminate interference as a problem. This higher frequency also means a shorter distance than the other standards/protocols (10-30 meters is generally accepted). The network is also a "mesh" network, which means the devices connect to each other. In terms of security, all three standards or protocols have pretty good encryption. All require at least 128 bit encryption at least. Z-Wave is limited to 232 devices, while Zigbee is only limited by bandwidth because it could conceivably have 65 000 devices on a network. Wifi is variable based on your router and your ability to have a mesh system in your home. When I'm advising people in terms of smart home protocols, I've now started to shift my tune away from Z-Wave. The reason is simply because of the lower bandwidth of Z-Wave and the unlikely ability to, in the future, have all the data I (and you) want to be moved around your home. Truthfully, even with all the advances in Zigbee and the new 3.0 standard, I think there's only one standard capable of handling the internet of things we're about to have in our homes. That standard is Wifi, and the new 802.11ax standard. You see, the new standard gives us increases on a magnitude of anywhere from 2 to 16 times more bandwidth and devices managed on one router. In a mesh system, that number will improve even further. So where you used to have 10-20 devices on one inexpensive router, you could now look towards 300 devices very comfortably on the same Wifi network. Overall, here's what I suggest: 1. People who own Z-Wave systems should begin the transition away. Get a Samsung SmartThings or Wink Hub 2 to bridge the gap and then begin to transition towards Zigbee, but more Wifi. 2. People just starting should do the same in terms of buying a Samsung SmartThings, Wink Hub 2, or an Echo Plus. The reason for that is Zigbee capability, but also the ability to build out a Wifi system. You could buy Z-Wave products if you wanted with Samsung or Wink, but my suggestion is that you keep that to a minimum. If you need any recommendations for home automation products, here's my Amazon Influencer Shop. Yes, I make money if you buy a product from Amazon through this link, but I've only included products I personally recommend. It's a curated list of high-quality smart home products. https://www.amazon.com/shop/automateyourlife Thanks for watching, and please subscribe below!

Well Check Out This Article! ► https://goo.gl/MhgYKZ SOCIAL MEDIA LINKS FOR THREE COMMAS INVESTING INSTAGRAM► https://www.instagram.com/richfromcrypto/ FACEBOOK ► https://www.facebook.com/threecommasinvesting/ We have seen a lot of interest in the IOTA currency over the past few weeks. Its value and market capitalization have grown beyond belief. In November we watched IOTA’s market cap octupled, securing this cryptocurrency’s top 4 rank across the board, ahead of Ripple, a well-established peer token. Born in 2014, it is currently the only technology of its kind. IOTA is a crypto token specially designed and optimized for the Internet-of-Things (IoT). The developers behind the project designed it in aims to support the 4th industrial revolution and machine economy, where machines trade resources and services with each other without third party involvement. IOTA was created as a derivation of the blockchain technology but is far more advanced. It’s already recognized in the innovation press like Forbes, Techcrunch, International Business Times and Huffington Post. IOTA is an open-source distributed ledger protocol that launched in 2015 which goes beyond blockchain with its next-generation public distributed ledger, which is called Tangle. In short, Tangle is a quantum-resistant Directed Acyclic Graph (DAG), whose digital currency, IOTA, has a fixed money supply with zero inflationary cost... and now to put that into English. In the near future, your phone and computer probably won’t be the only devices connected to the internet. Every physical device ranging from your fridge, oven, car, and even house may be interconnected via the internet. This inter-networking of equipment is called the Internet of Things (IoT), a market that is expected to be worth $267 billion and have 30 million devices connected by 2020. Although bitcoin and its underlying technology, the blockchain, have certainly proven their worth, they still have to prove themselves in terms of scalability. There is scaling issues regarding the limit to how many payments can be processed per second. The need for greater amounts of micro and nano payments will grow when industries and businesses start adopting the IoT. Miners also need an incentive to verify transactions, but what happens when mining is not sustainable anymore? As the Internet-of-Things keep expanding, the need for compatibility and sharing of resources become a necessity. IOTA has the ability to make every technological resource a potential service to be traded on an open market in real time, with no fees.

DEF CON 22 - Dan Kaminsky - Secure Random by Default
 
01:38:53
Secure Random By Default Dan Kaminsky Chief Scientist, White Ops As a general rule in security, we have learned that the best way to achieve security is to enable it by default. However, across operating systems and languages, random number generation is always exposed via two separate and most assuredly unequal APIs -- insecure and default, and secure but obscure. Why not fix this? Why not make JavaScript and PHP and Java and Python and even libc rand() return strong entropy? What are the issues stopping us? Should we just shell back to /dev/urandom, or is there merit to userspace entropy gathering? How does fork() and virtualization impact the question? What of performance, and memory consumption, and headless machines? Turns out the above questions are not actually rhetorical. Just because a change might be a good idea doesn't mean it's a simple one. This will be a deep dive, but one that I believe will actually yield a fix for the repeated *real world* failures of random number generation systems. Dan Kaminsky has been a noted security researcher for over a decade, and has spent his career advising Fortune 500 companies such as Cisco, Avaya, and Microsoft.Dan spent three years working with Microsoft on their Vista, Server 2008, and Windows 7 releases. Dan is best known for his work finding a critical flaw in the Internet’s Domain Name System (DNS), and for leading what became the largest synchronized fix to the Internet’s infrastructure of all time. Of the seven Recovery Key Shareholders who possess the ability to restore the DNS root keys, Dan is the American representative. Dan is presently developing systems to reduce the cost and complexity of securing critical infrastructure.

Intelligent Integration 2: UltraCMOS® Capability at Microwave Frequencies
 
04:39
Last year we showcased the incredible potential of CMOS when UltraCMOS® technology uses Intelligent Integration to provide the combination of reliability, smaller footprint, improved performance, greater system capability, and flexibility. We demonstrated this potential by releasing the world’s first RF switch to operate at zero Hertz, replacing mechanical relays while integrating Analog, digital, and rf functions on a single die in order to enable features such as Analog DC-offset voltage tracking, digital logic control, and high performance rf switching. Later we released our Monolithic Phase & Amplitude Controller, a single-chip, digitally-controlled solution used to optimize the performance of a Doherty power amplifier architecture. A single device which incorporates maximum phase and amplitude tuning flexibility for the carrier and peaking path with an integrated 90 degree splitter. And now we are extending our phase and amplitude control capability into the microwave domain for Analog signal processing. Using intelligent integration, UltraCMOS RFICs provide a clear advantage to applications such as Wireless Infrastructure, 5G, Beamforming, Interference Cancellation, and commercial SAR applications such as weather radar, air traffic control, and phased array antenna for satellites. For example, next generation cellular systems will rely more on beamforming antennas to improve data rates and provide users with better quality of service (pause) or QOS. These antennas require advanced signal processing capabilities in order to accurately steer multiple signals simultaneously. Leveraging the phase and amplitude control capability we’ve successfully developed for our MPAC product, we’re able to provide the phase and amplitude accuracy to enable fast, reconfigurable antennas for the next generation 5G solutions. Key to achieving the desired performance are intelligent arrays. In each antenna, the phase and amplitude of the signal can be independently and accurately controlled. Let’s take a look at a typical beamforming example using signals received from a wireless transmitter. With increased accuracy, resolution, and speed of reconfiguration, intelligent arrays can be further optimized for their overall performance – whether it be the fundamental beam pattern or reducing unwanted interferers, either through interference nulling during the receive function or through better side-lobe suppression during transmission. When the phase accuracy and resolution of the array is low the directionality of the beam is also low. Increasing the phase accuracy and resolution increases the directionality and the ability to focus the signal at a specific handset. Further fine tuning the phase relationships of all the elements in an array can create nulling effects that can be leveraged to mitigate effects of interferers and help reduce the level of interference generated, improving overall signal quality and giving the user better QOS. We’ve leveraged the success of the integrated phase and amplitude control of our MPAC products to start developing core chips that can utilize integrated digital capability to give the flexibility needed to tune gain and phase at fine resolution. Ideal for high density, compact arrays, such as the ones being developed for 5G, the UltraCMOS core chip uses intelligent integration to provide a flexible analog processing solution with digital programmability that works seamlessly together on a single, monolithic chip. Memory elements can be added to the core chip which allows pre-loading of configurations that can be automatically cycled at high speed. All of this without degradation in RF performance, especially linearity. And, UltraCMOS process consistency guarantees the reliability and repeatability of each device, resulting in a single-chip solution with the performance and versatility ideal for a wide-range of microwave applications. This Configurability, Flexibility, Repeatability, Ease of Use, and Performance is only possible with UltraCMOS technology. Intelligent Integration. UltraCMOS Technology.

DEF CON 23 - Colby Moore - Spread Spectrum Satcom Hacking
 
40:28
Recently there have been several highly publicized talks about satellite hacking. However, most only touch on the theoretical rather than demonstrate actual vulnerabilities and real world attack scenarios. This talk will demystify some of the technologies behind satellite communications and do what no one has done before - take the audience step-by-step from reverse engineering to exploitation of the GlobalStar simplex satcom protocol and demonstrate a full blown signals intelligence collection and spoofing capability. I will also demonstrate how an attacker might simulate critical conditions in satellite connected SCADA systems. In recent years, Globalstar has gained popularity with the introduction of its consumer focused SPOT asset-tracking solutions. During the session, I’ll deconstruct the transmitters used in these (and commercial) solutions and reveal design and implementation flaws that result in the ability to intercept, spoof, falsify, and intelligently jam communications. Due to design tradeoffs these vulnerabilities are realistically unpatchable and put millions of devices, critical infrastructure, emergency services, and high value assets at risk. Speaker Bios: Colby Moore is Synack's Manager of Special Activities. He works on the oddball and difficult problems that no one else knows how to tackle and strives to embrace the attacker mindset during all engagements. He is a former employee of VRL and has identified countless 0day vulnerabilities in embedded systems and major applications. In his spare time you will find him focusing on that sweet spot where hardware and software meet, usually resulting in very interesting consequences. Twitter: @colbymoore

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk. Using Ethereum, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone. You can even use the token you created earlier to keep track of the distribution of rewards.

William Oliver: "Quantum Engineering of Superconducting Qubits"
 
58:14
William Oliver visited the Google LA Quantum AI Lab on August 13, 2015. Abstract: Superconducting qubits are coherent artificial atoms assembled from electrical circuit elements. Their lithographic scalability, compatibility with microwave control, and operability at nanosecond time scales all converge to make the superconducting qubit a highly attractive candidate for the constituent logical elements of a quantum information processor. Over the past decade, spectacular improvement in the manufacturing and control of these devices has moved superconducting qubits from the realm of scientific curiosity to the threshold of technological reality. In this talk, we review this progress and present aspects of our work related to the quantum systems engineering of high-coherence devices and high-fidelity control. For more information: [1] J. Bylander, et al., Nature Physics 7, 565 (2011) [2] W.D. Oliver & P.B. Welander, MRS Bulletin 38, 816 (2013) Bio: William D.

SFI Community Lecture - Christopher Monroe - Quantum Computers
 
01:09:34
Quantum computers exploit the bizarre features of quantum mechanics to perform tasks that are impossible using conventional means. Sending instantaneous messages across long distances or quickly computing over ungodly amounts of data are just two possibilities that arise if we can design computers to exploit quantum uncertainty, entanglement, and measurement. In this SFI Community Lecture, scientist Christopher Monroe describes the architecture of a quantum computer based on individual atoms, suspended and isolated with electric fields, and individually addressed with laser beams. This leading physical representation of a quantum computer has allowed demonstrations of small algorithms and emulations of hard quantum problems with more than 50 quantum bits. While this system can solve some esoteric tasks that cannot be accomplished in conventional devices, it remains a great challenge to build a quantum computer big enough to be useful for society. But the good news is that we don’t see any fundamental limits to scaling atomic quantum computers, and Monroe speculates as to how this might happen. Christopher Monroe is a leading atomic physicist and quantum information scientist. He demonstrated the first quantum gate realized in any system at the National Institute of Standards and Technology (NIST) in the 1990s, and at University of Michigan and University of Maryland he discovered new ways to scale trapped ion qubits and simplify their control with semiconductor chip traps, simplified lasers, and photonic interfaces for long-distance entanglement. He received the American Physical Society I.I. Rabi Prize and the Arthur Schawlow Laser Science Prize, and has been elected into the National Academy of Sciences. He is Co-Founder and Chief Scientist at IonQ in College Park, MD.

Why Can't You Use Quantum Mechanics To Communicate Faster Than Light?
 
06:03
The EPR paradox, that we met in a previous video, tells us 2 entangled particles can effect each other no matter now far away they are. But then why can't we use them to send instant messages across the universe? Einstein's relativity tells us it would be a disaster if we could! Homework: Prove that faster than light communication doesn't work for the state in the video, when Alice measures up and down-ness, but Bob measures left-rightness. Look up and then explain the usefulness of a one-time pad. Also explain whether a one time pad coming from a bunch of shared particles is secure if Eve is trying to measure Bob's particle's before he does.

Moderated by Dr. Condoleezza Rice, Eric Schmidt, Executive Chairman of Google and Jared Cohen, Director of Google Ideas discuss how technology will change privacy and security, war and intervention, diplomacy, and terrorism. "When you empower people with tools like technology, democracy flourishes," said Schmidt. For the developing world, the arrival of the smartphone and access to the Internet is life-changing. For example, approximately one billion people in China are going to gain online access in a decade. Schmidt believes technology can empower people, solve literacy issues, and improve governments around the world.

Nadia Lopez: "The Bridge to Brilliance: How One Principal in a Tough [...] | Talks at Google
 
58:34
The Bridge to Brilliance: How One Principal in a Tough Community Is Inspiring the World In 2015, Nadia Lopez was struggling as the principal and founder of Mott Hall Bridges Academy, a middle school in one of America's poorest communities. She rose to an unlikely fame when the blog Humans of New York featured an eight grader from her school who, when asked "Who's influenced you the most in life?," responded with "My principal." The post received over 1M likes of Facebook, and thrust Lopez and her school into the internet spotlight. In "The Bridge to Brilliance," Lopez chronicles what happens after the internet fame ends. She describes the struggles of principals and teachers working to teach students in our nation's toughest schools. She brilliantly chronicles the founding of her school, and the highlights the plight of excellent educators to provide opportunities for all American children.

Quantum Computing Day 1: Introduction to Quantum Computing
 
56:29
Google Tech Talks December, 6 2007 ABSTRACT This tech talk series explores the enormous opportunities afforded by the emerging field of quantum computing. The exploitation of quantum phenomena not only offers tremendous speed-ups for important algorithms but may also prove key to achieving genuine synthetic intelligence. We argue that understanding higher brain function requires references to quantum mechanics as well. These talks look at the topic of quantum computing from mathematical, engineering and neurobiological perspectives, and we attempt to present the material so that the base concepts can be understood by listeners with no background in quantum physics. This first talk of the series introduces the basic concepts of quantum computing. We start by looking at the difference in describing a classical and a quantum mechanical system. The talk discusses the Turing machine in quantum mechanical terms and introduces the notion of a qubit. We study the gate model of quantum computing and look at the famous quantum algorithms of Deutsch, Grover and Shor. Finally we talk about decoherence and how it destroys superposition states which is the main obstacle to building large scale quantum computers. We clarify widely held misconceptions about decoherence and explain that environmental interaction tends to choose a basis in state space in which the system decoheres while leaving coherences in other coordinate systems intact.
