[DS15] Cryptography Tools, Identity Vectors for 'Djihadists' - Julie Gommes
 
34:49
Cryptography, social networks - today the use of online tools also serves to protect the communications of terrorists and to affirm their membership in terrorist organisations. The Internet is the method of choice for communication: the number of sites calling for a "jihad" rose from 28 in 1997 to over 5,000 in 2005. The basic use of these sites for the purpose of basic classical communication began in the 2000s. It was replaced by that of social networks, allowing almost instant mass communication. Studies of the Middle East Media Research Institute (MEMRI) show that Al-Qaeda uses encryption tools for a long time: "Since 2007, Al Qaeda's use of encryption technology has been based on the platform Mujahideen Secrets, which has incorporated the support for mobile, instant messaging, and Macs." Encrypting communications was only done for emails and within the "Mujahideen Secrets" platform itself. However the year 2013 was a turning point in the spread of encryption: instant messaging in February with Pidgin, SMS in September with Twofish encryption, AES encrypted texts on web sites in December. Edward Snowden's revelations, which began in June 2013, are not the starting point of the "cryptodjihad" but seem to have acted as an accelerator. MEMRI's researchers demonstrated the use of public cryptographic tools stemming from the family of Free Software: Pidgin instant messaging tool similar to MSN allows the terrorist movement Asrar al Dardashan to encrypt their communications with OTR (for off the record). By analyzing the adoption of new tools and the use of Free Software, we see that the focus is on cryptography for mobile tools. As a cybersecurity consultant, Julie has spent three years in the Arab world (Egypt, Syria, Sudan, Lyban, Tunisia ...). For several years she's been studying the jihadist movement and the rise of anonymization and encryption techniques in the Middle East. Author of a book about the revolutions in several of these countries "There were once revolutions" (Ed. The Seagull, 2012), she now works in particular studying international conflicts on the Internet.

Cryptographic Function Detection in Obfuscated Binaries via Bit-precise Symbolic Loop Mapping
 
23:43
Cryptographic Function Detection in Obfuscated Binaries via Bit-precise Symbolic Loop Mapping Dongpeng Xu (The Pennsylvania State University) Presented at the 2017 IEEE Symposium on Security & Privacy May 22–24, 2017 San Jose, CA http://www.ieee-security.org/TC/SP2017/ ABSTRACT Cryptographic functions have been commonly abused by malware developers to hide malicious behaviors, disguise destructive payloads, and bypass network-based firewalls. Now-infamous crypto-ransomware even encrypts victim’s computer documents until a ransom is paid. Therefore, detecting cryptographic functions in binary code is an appealing approach to complement existing malware defense and forensics. However, pervasive control and data obfuscation schemes make cryptographic function identification a challenging work. Existing detection methods are either brittle to work on obfuscated binaries or ad hoc in that they can only identify specific cryptographic functions. In this paper, we propose a novel technique called bit-precise symbolic loop mapping to identify cryptographic functions in obfuscated binary code. Our trace-based approach captures the semantics of possible cryptographic algorithms with bit-precise symbolic execution in a loop. Then we perform guided fuzzing to efficiently match boolean formulas with known reference implementations. We have developed a prototype called CryptoHunt and evaluated it with a set of obfuscated synthetic examples, well-known cryptographic libraries, and malware. Compared with the existing tools, CryptoHunt is a general approach to detecting commonly used cryptographic functions such as TEA, AES, RC4, MD5, and RSA under different control and data obfuscation scheme combinations.

WireGuard: Next Generation Secure Kernel Network Tunnel Cutting edge crypto, shrewd kernel design, …
 
38:58
WireGuard: Next Generation Secure Kernel Network Tunnel Cutting edge crypto, shrewd kernel design, and networking meet in a surprisingly simple combination by Jason A. Donenfeld At: FOSDEM 2017 WireGuard is a next generation VPN protocol, which lives in the Linux kernel,and uses state of the art cryptography. One of the most exciting recentcrypto-networking developments, WireGuard aims to drastically simplify securetunneling. The current state of VPN protocols is not pretty, with popularoptions, such as IPsec and OpenVPN, being overwhelmingly complex, with largeattack surfaces, using mostly cryptographic designs from the 90s. WireGuardpresents a new abuse-resistant and high-performance alternative based onmodern cryptography, with a focus on implementation and usability simplicity.It uses a 1-RTT handshake, based on NoiseIK, to provide perfect forwardsecrecy, identity hiding, and resistance to key-compromise impersonationattacks, among other important security properties, as well as highperformance transport using ChaCha20Poly1305. A novel IP-binding cookie MACmechanism is used to prevent against several forms of common denial-of-serviceattacks, both against the client and server, improving greatly on those ofDTLS and IKEv2. Key distribution is handled out-of-band with extremely shortCurve25519 points, which can be passed around in the likes of OpenSSH.Discarding the academic layering perfection of IPsec, WireGuard introduces theidea of a "cryptokey routing table", alongside an extremely simple and fullydefined timer-state mechanism, to allow for easy and minimal configuration;WireGuard is actually securely deployable in practical settings. In order torival the performance of IPsec, WireGuard is implemented inside the Linuxkernel, but unlike IPsec, it is implemented in less than 4,000 lines of code,making the implementation manageably auditable. These features converge tocreate an open source VPN utility that is exceedingly simple, yet thoroughlymodern and secure. The presentation will be divided up into several parts. First, there will bean overview of the problems with IPsec, OpenVPN, and other popular VPNs,outlining attacks and weaknesses. Next, the WireGuard idea of the "cryptokeyrouting table" will be introduced, and we’ll walk through several propertiesderived from it. This will transition into a discussion of the timer statemechanism, and how secure protocols are necessarily stateful, but it’spossible to make them appear stateless to the user by exhaustively definingall possible state transitions. Then we’ll get into the hardcore meat of thepresentation: the cryptography and various crypto innovations behindWireGuard. We will discuss the triple Diffie-Hellman, the role of combiningstatic and ephemeral keys, the performance and DoS-potential of Curve25519point multiplication, using a PRF chaining for rotating keys, identity hidingand remaining silent on a network, and clever usage of authenticatedencryption with additional data. We will examine the various attack models,and enumerate the cryptographic mitigations employed by WireGuard. The sumwill be a comprehensive overview of modern day crypto tricks, attacks, anduseful constructions, and how these insights have been funneled intoWireGuard. Finally, we’ll examine the Linux kernel implementation ofWireGuard, seeing how it’s possible to avoid allocations in response tounauthenticated packets as a defense coding technique. During thepresentation, a live WireGuard endpoint will be provided to audience memberswho wish to send packets, whether encrypted, legitimate, malformed, dubious,or otherwise curious. Threaded throughout will be an enumeration of attacks on existing protocolsand cryptographic tricks for their mitigation. My background is in security -- kernels, hardware, reversing, crypto, largenetworks, etc -- and as such I've broken a lot of systems with some noveltricks and protocol insights. WireGuard is motivated by a sort of cornucopiaof clever attacks (crypto and otherwise) against other networks. I made itbecause I wanted something I could actually confidently run on my owninfrastructure, and none of the other tools were nearly up to the task. So,this talk is going to go into depth about real attacks on various protocols,in addition to unveiling some techniques to avoid entire classes of attacks. Finally, since WireGuard is initially implemented for the Linux kernel, therehave been some very interesting considerations to account for with kernelprogramming. Cross platform implementations are also in the works, written inGo and Rust. Room: Janson Scheduled start: 2017-02-05 13:00:00

HAIC Talk: The Advertisement Exchange – with Moti Yung
 
01:23:59
Developing of Systems within a global infrastructure (or a cloud) has to take into account that the underlying system will evolve, new versions of software will develop, and if the system is successful then further services will be added. The development of security tools to such systems has to consider agility and scale-up of the initial design and adaptation to the evolving nature of the system. In fact, we argue that this is a basic principle in deployment of security solutions in modern global ecosystems. For example, cryptographic solutions have to be designed with extended scope in mind and with enough flexibility to allow the growing system to be able to exploit the existing cryptographic tools and methods (since a drastic change may be overly complex and will result in much development overhead). We demonstrate this “agility principle” by reviewing the development of cryptographic solution to Google’s global Advertisement Exchange (ADX), which is the system managing auctions for placing banner ads throughout the Internet. Watch the Q&A here: https://youtu.be/ek0QNdELFGs Moti Yung is a Security and Privacy Scientist with a main interest in Cryptography: its Theory and its Real life Applications. He graduated from Columbia University in 1988 and is an adjunct senior research faculty at Columbia till today. In parallel he has had an industrial research career working at places like IBM, RSA Labs. (EMC), Google, and Snap. Yung is a fellow of ACM, of IEEE, of the International Association for Cryptologic Research (IACR) and the European Association for Theoretical Computer Science (EATCS). Among his awards are ACM’s SIGSAC Outstanding Innovation Award in 2014, and 2018 IEEE Computer Society W. Wallace McDowell Award. His research covers broad areas: from the theory and foundations, to applied systems, and actual engineering efforts of cryptography and secure systems.

Secure Communication

Secure Communication: Public Key Cryptography ------------------------------------------------------------------------------ The internet is a very powerful and useful tool of communication, information, and connectivity. It is very important to keep yourself safe and secure online. There are many ways to be targeted, and this video will teach you how to keep private while communicating on the internet. The best way to secure a message is though encryption. Ciphers and cryptography have been used throughout history to keep data safe from prying eyes. Encryption ----------------- What is encryption? Encryption is the conversion of human readable data, such as a message, to a gibberish called ciphertext. The ciphertext can then only be decoded and read using a certain key or password. In this example, encryption converts "This is really fun!" to a whole bunch of letters and numbers that are unreadable. Examples: Alice and Bob ---------------------------------------- Normal Communication: Lets say that Alice and Bob are best friends who want to stay in touch over the internet. They text each other, send emails, or use a messaging app. This works, but there is no way of knowing who might be listening in. Intercepted Communication: Another person, who we'll call Eve, can intercept any data Alice and Bob send to each other. This is called a man-in-the-middle attack, and allows Eve to read anything transmitted, leaving Alice and Bob with no privacy, and no knowledge that they were overheard. Encrypted Communication: This is where encryption comes in. If Eve can't read the data, it becomes useless to her! Alice encrypts the data, represented here by the lock, then sends the encrypted message to Bob. However, Bob needs the key or password to unlock the encrypted message. Alice can't just send the key, Eve could get it! Alice and Bob also can't meet up in person, the internet is global and they could be anywhere. So how does Alice get the key safely to Bob so he can unlock her message? Public Key Exchange: The solution is public key exchange. Alice and Bob each receive open locks, called public keys. They give these open locks to each other and the world, and keep the key to these locks private. Now if Bob wants to send Alice a message, he encrypts or locks his message using her open lock and sends her the message. She can then open the message using her own matching private key. Use of Public Key Cryptography --------------------------------------------------- That was the basic principles of how public key exchange works. It is used to secure data in many places, including HTTPS in websites, which is the little green lock you may have seen in your browser. Both types of locks are secure. If you want to use public key cryptography yourself, there are many tools available. How to Communicate Securely Yourself With Public Key Cryptography ---------------------------------------------------------------------------------------------------------------- OnlinePGP (http://onlinepgp.ws/) is a website which lets you create your own public and private keys. You enter some basic information, a password, and how secure you want to be. Then you can generate your own key pair. Your public key is your open lock that you can share with everybody. Your private key you use to open messages secured with your lock. Now if you want to send someone a secure message, first write a message, then use their public key, the open lock, to encrypt that message. The encrypted message can now only be read by the person whose public key you used. Copy and paste it and send it to them. To decrypt and read it, they paste the secure message, along with their private key and their own password, and then hit decrypt. You have now successfully communicated securely! Easily Communicate Securely ------------------------------------------------ That was a lot of work to send a secure message. Luckily, there are many great apps which do all of this for you! Telegram is the best secure communication client today. It is on your phone, your computer, and the web. It uses the principles you just learned and gives you the privacy you deserve on the internet.
