DEF CON 22 - Dan Kaminsky - Secure Random by Default
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.

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Key logging-resistant Visual Authentication Protocols The design of secure authentication protocols is quite challenging, considering that various kinds of root kits reside in PCs (Personal Computers) to observe user’s behavior and to make PCs untrusted devices. Involving human in authentication protocols, while promising, is not easy because of their limited capability of computation and memorization. Therefore, relying on users to enhance security necessarily degrades the usability. On the other hand, relaxing assumptions and rigorous security design to improve the user experience can lead to security breaches that can harm the users’ trust. In this paper, we demonstrate how careful visualization design can enhance not only the security but also the usability of authentication. To that end, we propose two visual authentication protocols: one is a one-time-password protocol, and the other is a password-based authentication protocol. Through rigorous analysis, we verify that our protocols are immune to many of the challenging authentication attacks applicable in the literature. Furthermore, using an extensive case study on a prototype of our protocols, we highlight the potential of our approach for real-world deployment: we were able to achieve a high level of usability while satisfying stringent security requirements.

Zerocash: Addressing Bitcoin's Privacy Problem
A Google TechTalk, 8/28/17, presented by Alessandro Chiesa Abstract: In Bitcoin, a payment's details are broadcast in the clear, so that anyone can verify its validity. Unfortunately, this violates user privacy and sacrifices coin fungibility. I will describe the Zerocash protocol, which uses zero knowledge proofs to achieve privacy-preserving payments in a Bitcoin-like system. This protocol was recently deployed in the wild, as part of the cryptocurrency Zcash. About the Speaker: Alessandro Chiesa is an assistant professor in the Department of Electrical Engineering and Computer Science at UC Berkeley. His research spans the areas of complexity theory, cryptography, and security, and focuses on the theoretical foundations and practical implementations of cryptographic proof systems such as zero knowledge proofs. He is a co-inventor of Zerocash and co-founder of Zcash. He is an author of libsnark, the leading open-source library for succinct zero knowledge proofs. He has received a Ph.D. in computer science from MIT in 2014, and B.S. degrees in computer science and in mathematics from MIT in 2009.

Generating OATH codes on your mobile the right way: with the YubiKey NEO
Worried about storing the secrets used to generate those OATH codes used by 2-step verification on your mobile? With the YubiKey NEO and our OATH applet, you can store them instead securely on your YubiKey NEO and use ANY NFC equipped smartphone or tablet to display the current set. See this in operation in this video. SCRIPT: Welcome to Yubico! In this video, I'm going to show the YubiKey NEO loaded with our OATH applet being used with my Android smartphone to display OATH one time passcodes or OTP. These OTPs are used for two step verification with services such as Google Apps, DropBox, HotMail and so on. The one time passcodes are 6 or 8 digit numbers that change every 30 seconds or on every request. You may already have the Google Authenticator app on your smart phone; beware - the crytographic secrets used to generate the next code are stored on the device and could be phished by malware. It's also difficult to move the credentials to another device. With the YubiKey NEO and OATH applet, you carry those secrets on your key chain, and can use any NFC equipped phone or tablet with the YubiOATH app to display the current set of one time passcodes; once set up, the cryptographic secrets never leave the safety of your YubiKey NEO! I've downloaded the YubiOATH app from Google's Play Store. Let's run it. When I tap my YubiKey NEO on the back of my Galaxy Nexus it shows my credential list is empty. Let's add a new credential. These are generally displayed by the service as a QR Code - I have setup a test code in my browser. From the menu I select "Scan new QR-code" point the camera at my browser and the app captures the credential details. I tap my YubiKey NEO to my phone and the credential is securely stored on my NEO and erased from the phone and the display shows the current OTP. Notice the timer bar - once 30 seconds passed, the OTP is greyed out. To get the next OTP, I just tap again and it updates the OTP. I can store many credentials on my YubiKey NEO - I have several on another NEO - let's see them: I tap that NEO on the back on my phone and the list of OTPs is displayed. I can also password protect my credentials on my NEO and delete expired credentials. Want to know more?

CppCon 2017: Matt Kulukundis “Designing a Fast, Efficient, Cache-friendly Hash Table, Step by Step”
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2017 — Hash tables consume a large volume of both compute resources and memory across Google's production system. The design for hash tables in C++ traces its origins to the SGI STL implementation from 20 years ago. Over these years, computer architecture and performance has changed dramatically and we need to evolve this fundamental data structure to follow those changes. This talk describes the process of design and optimization that starts with std::unordered_map and ends with a new design we call "SwissTable", a 2-level N-way associative hash table. Our implementation of this new design gets 2-3x better performance with significant memory reductions (compared to unordered_map) and is being broadly deployed across Google. — Matt Kulukundis: Google, Senior Software Engineer Matt is a senior software engineer on the C++ libraries team at Google. Prior to Google he has worked on compilers, machine learning, and underwater robotics. In his free time, he scuba dives in warm places. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

2017/18 CACR Security Speaker- Lorrie Cranor "Tales of an Accidental Computer Science Professor"
Lorrie Cranor- "Tales of Accidental of an Accidental Computer Science Professor" Lorrie is the FORE Systems Professor of Computer Science and of Engineering and Public Policy at Carnegie Mellon University where she is director of the CyLab Usable Privacy and Security Laboratory (CUPS). How can we put privacy policies on every smart light bulb and thermostat, and who would want to read them all anyway? How can we help people create stronger passwords without increasing the chance that they will forget them? Why do people think about monkeys when they create passwords and turtles when they draw pictures of privacy? I’ll share highlights of my journey from student journalist to “accidental” computer science professor, with stints in technical standards, entrepreneurship, fiber arts, fashion design, and government service. I’ll talk about how I became interested in making privacy and security usable, and some of the research problems I’ve investigated at the intersection of security, privacy, usability, and human behavior. I’ll discuss ways to attack security user study participants without actually putting them at risk; how we determined that many people will pay extra for better privacy when shopping online; and how the Today Show camera crew ended up in my kitchen.

Phishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites, auction sites, banks, online payment processors or IT administrators are commonly used to lure unsuspecting public. Phishing emails may contain links to websites that are infected with malware. Phishing is typically carried out by email spoofing or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Phishing is an example of social engineering techniques used to deceive users, and exploits the poor usability of current web security technologies. Attempts to deal with the growing number of reported phishing incidents include legislation, user training, public awareness, and technical security measures. Phishing is a continual threat that keeps growing to this day. The risk grows even larger in social media such as Facebook, Twitter, Myspace etc. Hackers commonly use these sites to attack persons using these media sites in their workplace, homes, or public in order to take personal and security information that can affect the user and the company (if in a workplace environment). Phishing is used to portray trust in the user since you can usually not tell that the site or program being visited/ used is not real, and when this occurs is when the hacker has the chance to access the personal information such as passwords, usernames, security codes, and credit card numbers among other things.

DEF CON 22 - Ladar Levison and Stephen Watt - Dark Mail
Slides Here: https://defcon.org/images/defcon-22/dc-22-presentations/Levison-Watt/DEFCON-22-Levison-Watt-Dark-Mail-UPDATED.pdf Dark Mail Ladar Levison FOUNDER OF LAVABIT, LLC Stephen Watt LEAD DEVELOPER, REFERENCE IMPLEMENTATION, DARK MAIL Data privacy and anonymity have long been cornerstone interests of the computer security world, but not particularly important to the general public. News events in the past year have seen the political climate shift radically, and now data privacy has become big business with secure mail solutions being the focal point of this new found attention. Dark Mail is not the only solution in the secure mail space, but just as Lavabit’s preoccupation with privacy and user autonomy was a rarity when it started over a decade ago, it hopes once again to push mail security forward into a new frontier. It is Dark Mail's objective to achieve the highest degree of security possible - with the introduction of an interoperable mail protocol as an open standard. To that end, we are publishing documents describing the protocol, along with a reference implementations of the client and server under a free software license. What most of the secure email systems in the privacy race have prioritized in tandem are ease of use for the masses, and cryptographically secure encryption of message contents between a sender and recipient. Additionally, they tend to place trust for private key management and encryption in the hands of the end user, and not the mail server. While this would certainly be an improvement over traditional SMTP, it leaves much to be desired. Where do other solutions fall short? Metadata. Dark Mail is designed to minimize the leakage of metadata so that ancillary information like subject lines, recipients, and attachments doesn’t fall into the hands of curious third parties. That means all information about the mail and its contents are completely opaque to everybody but the parties communicating - including the servers handling the messages in transit. Accomplishing these goals wasn’t possible using existing standards, which is why we created a security enhanced flavor of SMTP for mail delivery dubbed DMTP. What separates dmail from competing secure mail designs is the level of security it affords the user while retaining its simplicity of use. We have automated the key management functions, so complex cryptography operations are handled without user interaction. Of equal importance is the need for an implementation that is open to peer review, security audits, and cryptanalysis. Unlike many commercial solutions, dmail isn’t tethered to a single centralized provider; instead it offers the ability for anybody to host secure mail services. Like today, users will be able to access their mail from anywhere, using a web client with client-side encryption, or a traditional client application on their mobile or desktop device for an even greater degree of security. An open standard will guarantee that users have the freedom to adopt any dmail-compatible client or server implementation of their choosing. Most attendees of this presentation will be familiar with the curious story of Lavabit's demise. While Lavabit's hosted mail service refused to surrender unfettered access to its users' secrets, this course of action may not be the obvious choice for network administrators placed in similar situations. Most digital surveillance efforts require the service provider to be complicit with the wiretapping requests of law enforcement. Dmail aims to protect messages from surveillance and tampering - whether it be subversive or coerced - by placing that capability beyond the reach of service providers. With dmail the keys belong to the user, and the message decryption occurs on the user’s device. Even so, users can choose how much to trust a service provider - with standardized modes that reside at different points along the security vs usability spectrum.

Developer Friendly Cryptography | Brice Williams | Hackers of CypherCon
(S1: E5) Software developers often make mistakes when using cryptography in applications, which tends to result in code with dangerous and subtle weaknesses. Some of this can be addressed through training, but should we expect all developers to be cryptography experts? Many developers only know to avoid writing their own ciphers, and rely on one of the many incomplete or incorrect code examples that exist on the internet. To make things worse, most cryptographic libraries in use today are designed to be used by experts and often result in misunderstandings by the average application developer. In this talk we will look at some common cryptography usage errors and why popular libraries often fall short. We will also discuss nuances such as backwards compatibility, FIPS 140-2 validation, and weak standards such as JOSE/JWT that contribute to the overall confusion. Brice will share some advice that you can provide to the development/engineering teams in your organization to not only make their job easier, but also ensure more secure cryptographic implementations.

DEF CON 24 - Guevara Noubir, Amirali Sanatinia - Honey Onions: Exposing Snooping Tor HSDir Relays
Tor is a widely used anonymity network that protects users' privacy and and identity from corporations, agencies and governments. However, Tor remains a practical system with a variety of limitations, some of which were indeed exploited in the recent past. In particular, Tor's security relies on the fact that a substantial number of its nodes do not misbehave. Previous work showed the existence of malicious participating Tor relays. For example, there are some Exit nodes that actively interfere with users' traffic and carry out man-in-the-middle attacks. In this work we expose another category of misbehaving Tor relays (HSDirs), that are integral to the functioning of the hidden services and the dark web. The HSDirs act as the DNS directory for the dark web. Because of their nature, detecting their malicious intent and behavior is much harder. We introduce, the concept of honey onions (honions), a framework to detect misbehaving Tor relays with HSDir capability. By setting up and deploying a large scale honion over Tor for more than 72 days, we are able to obtain lower bounds on misbehavior among HSDirs. We propose algorithms to both estimate the number of snooping HSDirs and identify them, using optimization and feasibility techniques. Our experimental results indicate that during the period of our work at least 110 such nodes were snooping information about hidden services they host. We reveal that more than half of them were hosted on cloud infrastructure and delayed the use of the learned information to prevent easy traceback. Furthermore, we provide the geolocation map of the identified snooping Tor HSDirs Bio: Guevera Noubir holds a PhD in Computer Science from EPFL and is currently a Professor at Northeastern University.

Voting Insecurity: Why We Won't be Able to Verify the Outcome of the 2016 Election
Partially as a result of hanging chads, almost $4 billion dollars was allocated by Congress in 2002 to "modernize" our elections. The rush to spend money before there were any meaningful federal standards or testing resulted in the purchase of a large number of poorly designed and insecure voting systems. Most of these old systems still in use are way past their use-by date, with ancient software that may no longer be maintained and physical components in need of replacements that may no longer be manufactured. Election officials trying to cope with failing voting systems and inadequate funding may consider what they hope are cheaper alternatives, such as Internet voting. This talk by Barbara Simons, an expert on electronic voting, will present a very brief overview of how we got to where we are today and what needs to be done (both technical and legal) to move to an evidence based voting system. She will also discuss some of the false claims made about Internet voting, as well as why Internet voting is a major security threat to our democracy.

USENIX Enigma 2016 - Internet Voting: What Could Go Wrong?
J. Alex Halderman, University of Michigan Internet voting has the potential to ease voter participation and provide a high-tech upgrade to traditional polling methods. Unfortunately, it also raises some of the most difficult challenges in computer security, due to the need to safeguard election servers and voters' computers against powerful attackers, while simultaneously protecting the secret ballot. How well can election technology defend against modern security threats? To find out, colleagues and I performed in-depth security evaluations of Internet voting systems used in the U.S. and around the world. We found staggering gaps in system designs and operational procedures—problems that would allow attackers to change votes, compromise privacy, disrupt returns, or cast doubt on election results. These case studies illustrate the practical obstacles to securing Internet voting and carry lessons for any locality considering adopting such systems.

Depending on the particular implementation, e-voting may use standalone electronic voting machines (also called EVM) or computers connected to the Internet. It may encompass a range of Internet services, from basic transmission of tabulated results to full-function online voting through common connectable household devices. The degree of automation may be limited to marking a paper ballot, or may be a comprehensive system of vote input, vote recording, data encryption and transmission to servers, and consolidation and tabulation of election results. A worthy e-voting system must perform most of these tasks while complying with a set of standards established by regulatory bodies, and must also be capable to deal successfully with strong requirements associated with security, accuracy, integrity, swiftness, privacy, auditability, accessibility, cost-effectiveness, scalability and ecological sustainability. Electronic voting technology can include punched cards, optical scan voting systems and specialized voting kiosks (including self-contained direct-recording electronic voting systems, or DRE). It can also involve transmission of ballots and votes via telephones, private computer networks, or the Internet. In general, two main types of e-voting can be identified: e-voting which is physically supervised by representatives of governmental or independent electoral authorities (e.g. electronic voting machines located at polling stations); remote e-voting via the Internet (also called i-voting) where the voter submits their votes electronically to the election authorities, from any location.
