57:46
Naivety of Creating Cross-Platform, Modern C++ Libraries: A Tour Of Our Challenges and Successes http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2017 — The AWS SDK for C++ was designed with a few important tenets. Modern C++ (versions 11 and later), Cross-Platform, User Customization with sane defaults, and no dependencies. A year after launching for general availability, we've been thinking about how these tenets have served us well, and the challenges we've encountered when applying them. In this talk, we will discuss the difficulties we encountered in design and implementation, and then we will cover the aspects of our design that have worked out well. The topics we will cover are: Build System choices, the C++ standard library, Dependency choices, Threading models, Memory models, IO-based programming, ABI compatibility, and packaging. — Jonathan Henson: Senior Software Dev. Engineer, Amazon Web Services, Inc Jonathan is a Senior Software Engineer at Amazon Web Services. He leads development on the AWS SDK for C++ and is passionate about writing tooling for modern C++ developers and advancing adoption of the latest C++ standards. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

The Hidden World of Crypto - The Linux Cryptography API Part II
 
43:14
The Linux kernel has a rich and modular cryptographic API that is used extensively by familiar user facing software such as Android. It's also cryptic, badly documented, subject to change and can easily bite you in unexpected and painful ways. This talk will describe the crypto API, provide some usage example and discuss some of the more interesting in-kernel users, such as DM-Crypt, DM-Verity and the new file system encryption code. Slides available at: https://www.slideshare.net/kerneltlv/linux-kernel-cryptographic-api-and-use-cases Gilad Ben-Yossef is a principal software engineer at ARM. He works on the kernel security sub-system and the ARM CryptCell engine. Open source work done by Gilad includes an experiment in integration of network processors in the networking stack, a patch set for reducing the interference caused to user space processes in large multi-core systems by Linux kernel “maintenance” work and on SMP support for the Synopsys Arc processor among others. Gilad has co-authored O’Reilly’s “Building Embedded Linux Systems” 2nd edition and presented at such venues as Embedded Linux Conference Europe and the Ottawa Linux Symposium, as well as co-founded Hamakor, an Israeli NGO for the advancement for Open Source and Free Software in Israel. When not hacking on kernel code you can find Gilad meditating and making dad jokes on Twitter.

KRACK Attacks: Bypassing WPA2 against Android and Linux

This video explains some of the academic research performed in the ACM CCS 2017 paper "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2". It's not a guide or tutorial on how to hack people. Instead, the video was made to make people aware of potential risks, and to motivate everyone to update their smartphone and laptop. By updating your devices you (normally) avoid the risks mentioned in the video! For additional information visit https://www.krackattacks.com Note that devices different from Android and Linux are less affected by the attack. That's because only Android and Linux (re)install an all-zero encryption key.

Vapor apps are very concise and even more powerful. * With autocomplete, debugging, and breakpoints you'll spend more time creating and less time fixing. About Swift (from Wikipedia) Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of extant Objective-C (ObjC) code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C, and more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and, on platforms other than Linux, uses the Objective-C runtime library, which allows C, Objective-C, C++ and Swift code to run within one program. Swift supports the core concepts that made Objective-C flexible, notably dynamic dispatch, widespread late binding, extensible programming and similar features. These features also have well-known performance and safety trade-offs, which Swift was designed to address. For safety, Swift introduced a system that helps address common programming errors like null pointers, and introduced syntactic sugar to avoid the pyramid of doom that can result. For performance issues, Apple has invested considerable effort in aggressive optimization that can flatten out method calls and accessors to eliminate this overhead. More fundamentally, Swift has added the concept of protocol extensibility, an extensibility system that can be applied to types, structs and classes. Apple promotes this as a real change in programming paradigms they term "protocol-oriented programming". Swift was introduced at Apple's 2014 Worldwide Developers Conference (WWDC). It underwent an upgrade to version 1.2 during 2014 and a more major upgrade to Swift 2 at WWDC 2015. Initially, a proprietary language, version 2.2 was made open-source software and made available under Apache License 2.0 on December 3, 2015, for Apple's platforms and Linux. IBM announced its Swift Sandbox website, which allows developers to write Swift code in one pane and display output in another. A second free implementation of Swift that targets Cocoa, Microsoft's Common Language Infrastructure (.NET), and the Java and Android platform exists as part of the Elements Compiler from RemObjects Software.[20] Since the language is open-source, there are prospects of it being ported to the web.[21] Some web frameworks have already been developed, such as IBM's Kitura, Perfect[22][23] and Vapor. An official "Server APIs" work group has also been started by Apple,[24] with members of the Swift developer community playing a central role.

The Last HOPE (2008): Crippling Crypto: The Debian OpenSSL Debacle
 
56:04
Saturday, July 19, 2008: 12:00 pm (Turing): In May 2008, a weakness in Debian was discovered which makes cryptographic keys predictable. A Debian-specific patch to OpenSSL broke the pseudo-random number generator two years ago, which led to guessable SSL and SSH keys. The vulnerability allows for impersonation of secure servers, as well as the potential to login to SSH secured systems. Since many popular derivatives like Ubuntu and Xandros are affected, the weak keys are found all over the Internet. The panel will present their approach to generating lists of weak keys using cloud computing and explain how they collected large numbers of SSL certificates of which several thousand are weak.

How to Exploit openSSL Heartbleed Vulnerability on android Phone
 
02:20
Basically, OpenSSL is an encryption library used in HTTPS communication. When most think of HTTPS communication, they think of the little lock icon that shows up in the browser bar when you visit online stores and banking websites. HTTPS is supposed to be the “secured” version of regular HTTP communication. Any data communication using SSL should be secure and encrypted. But with the latest OpenSSL vulnerability, unencrypted information can be recovered from a vulnerable system from specially crafted heartbeat messages. During communication, OpenSSL uses a “heartbeat” message that echoes back data to verify that it was received correctly. The problem is, in OpenSSL 1.0.1 to 1.0.1f, a hacker can trick OpenSSL by sending a single byte of information but telling the server that it sent up to 64K bytes of data that needs to be checked and echoed back.

LibreSSL presentation by Bob Beck to Calgary UNIX Users' Group (CUUG)
 
01:37:07
LibreSSL: an Open-Source Replacement for OpenSSL Sometimes You Just Gotta Say, "Fork It!" In April 2014, the Heartbleed security bug came to the world's attention. Sites using the OpenSSL Transport Layer Security (TLS) library were vulnerable to attacks exposing private information (which could include passwords and financial data) to malicious third parties. Since a significant fraction of all web sites use OpenSSL, this was a very serious problem. Always concerned about security, the OpenBSD team assessed the situation and concluded that the OpenSSL group was not up to the task of repairing the damage and providing a secure implementation for future use. Instead of simply waiting for OpenSSL to improve on its own, OpenBSD developers decided to get directly involved and produce an API-compatible fork, named LibreSSL. Initially, LibreSSL is specifically targeted only for OpenBSD. Much of the cruft in the original OpenSSL code base is being removed, leaving a simpler and more maintainable core. Once that is stable, ports to other operating systems are expected to follow. Bob Beck, who is spearheading the LibreSSL development effort, discusses the background, current efforts, and possible future directions for LibreSSL. Theo de Raadt, OpenBSD founder and never shy with his opinions, was also present and chimed in with some comments. This presentation took place at the May 2014 meeting of the Calgary UNIX Users' Group (CUUG).

HTTPS proxy - Google Calendar - Zorp GPL
 
01:49
The application-level proxy technology gives you the possibility to keep your data stored in a cloud confidential. The video demonstrates that Zorp can analyze the traffic between the client (Thunderbird) and the cloud service (Google Calendar), identify the sensitive parts (for example description), encrypt them when they go to the cloud service provider, and decrypt them when they go back. The video demonstrates that the traffic between Thunderbird and Google Calendar can be intercepted by Zorp. Zorp, as an application-level firewall technology, terminates the secure (HTTPS) connection between the client and the server, decrypts it on the client-side, parses, analyzes, potentially modifies it, and encrypts it again on the server-side. On the firewall, the plain traffic is accessible. In this point of view, it is a man-in-the-middle but it is controlled by network administrator. When the calendar data goes to Google, Zorp encrypts the sensitive parts in it (for example description) so after they leave the private network which is protected by Zorp, they cannot be accessed neither by the cloud provider nor by the crackers. As the web access is not intercepted by Zorp, data decryption does not take place, so only the encrypted data can be seen in the browser. To prevent any misunderstandings: the video shows only the proof of concept of the transparent encryption of sensitive data on a network security device. Keep in mind that base64, is definitely not an encryption algorithm, but it is quite good for demonstration purposes. It can be changed to any kind of encryption algorithm, like public-key cryptography. http://www.balabit.com/network-security/zorp-gpl

DEF CON 23 - Ionut Popescu - NetRipper: Smart Traffic Sniffing for Penetration Testers
 
41:56
The post-exploitation activities in a penetration test can be challenging if the tester has low-privileges on a fully patched, well configured Windows machine. This work presents a technique for helping the tester to find useful information by sniffing network traffic of the applications on the compromised machine, despite his low-privileged rights. Furthermore, the encrypted traffic is also captured before being sent to the encryption layer, thus all traffic (clear-text and encrypted) can be sniffed. The implementation of this technique is a tool called NetRipper which uses API hooking to do the actions mentioned above and which has been especially designed to be used in penetration tests, but the concept can also be used to monitor network traffic of employees or to analyze a malicious application. Speaker Bio Ionut works as a Senior Security Consultant at KPMG in Romania. He is passionate about ASM, reverse engineering, shellcode and exploit development and he has a MCTS Windows Internals certification. He spoke at various security conferences in Romania like: Defcamp, OWASP local meetings and others and also at the yearly Hacknet KPMG international conference in Helsinki and Berlin. Ionut is also the main administrator of the biggest Romanian IT security community: rstforums.com and he writes technical articles on a blog initiated by a passionate team: securitycafe.ro.

Heartbleed-Check App For Android Released
 
00:46
They're looking for blood! Lookout Mobile Security has released a free app called Heartbleed Detector that checks to see whether an Android device is vulnerable to the Heartbleed bug. The Heartbleed bug, a serious error in an encryption library called OpenSSL that makes it devastatingly easy to grab supposedly secure data, mostly affects Web and email servers. However, Android 4.1.1 (a.k.a. Jelly Bean) does use a vulnerable version of the OpenSSL software. Heartbleed Detector checks to see if you're running a vulnerable version of Android, and whether the vulnerable extension to OpenSSL is enabled on your device. http://news.yahoo.com/heartbleed-check-app-android-released-173114825.html http://www.wochit.com

ScreenCast: Using sFTP with SSH, and why FTP is Insecure
 
07:08
In our video we talk about the importance of data encryption across the wire, as well as over the air, and show how attackers can take advantage of non-encrypted data transfer. We hack FTP using an ARP attack. Our alternative to FTP is sFTP, which utilizes the SSH (Secure Shell) protocol for file transfers, providing a fully [public key] encrypted path for the data to flow. We are essentially mitigating any MITM (Man in the Middle) attacks, or network sniffing; where an attacker simply jumps onto your network and steals confidential information as it flows. By using encrypted data transfer, the data can still be sniffed and logged, but it is nearly impossible to make useful. More at http://blog.primestudiosllc.com

kali linux :-How to use cupp.py tool to create word list
 
03:23
The most common form of authentication is the combination of a username and a password or passphrase. If both match values stored within a locally stored table, the user is authenticated for a connection. Password strength is a measure of the difficulty involved in guessing or breaking the password through cryptographic techniques or library-based automated testing of alternate values. A weak password might be very short or only use alphanumberic characters, making decryption simple. A weak password can also be one that is easily guessed by someone profiling the user, such as a birthday, nickname, address, name of a pet or relative, or a common word such as God, love, money or password. That is why CUPP has born, and it can be used in situations like legal penetration tests or forensic crime investigations. download description of cupp is :-https://github.com/Mebus/cupp

Totty- An Introduction to OpenSSH for System Administrators and Students
 
10:53
Security is of great concern in the information technology world. Bank transaction, medical records, and stock exchanges are only a few examples of sensitive information that needs to be encrypted during transaction to protect the privacy of the data being transmitted. OpenSSH is an open source re-implementation of the closed source commercial-only Secure Shell |SSH| protocol. OpenSSH provides secure encryption in order to protect data if intercepted during transmission. As explained by openssh.org, "OpenSSH encrypts all traffic |including passwords| to effectively eliminate eavesdropping, connection hijacking, and other attacks.” Linux distributions use the OpenSSH protocol and Windows systems use the proprietary SSH protocol. OpenSSH provides encryption to secure transactions in order to prevent intercepted messages from being read. The command to use OpenSSH in a Linux distribution is simply “ssh” and OpenSSH is commonly referred to as SSH in casual conversation. According the the Red Hat Enterprise Linux 6 Deployment Guide, "To ensure maximum security for your connection, it is recommended that only SSH version 2-compatible servers and clients are used whenever possible.” OpenSSH uses the library called OpenSSL and is explained by openssl.org as, “The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer |SSL v2/v3| and Transport Layer Security |TLS v1| protocols as well as a full-strength general purpose cryptography library.” Plain text protocols were originally developed when the concept of security was much different. Efficiency and ease of use is incorporated into the plain text protocols, but security was not of the same concern during the plain text protocol design era. Some examples of plain text protocols include File Transfer Protocol |FTP| and Telnet. Both of these protocols can be intercepted during network transfer. Wire sniffers such as WireShark or tshark can be used to view transactions that occurred in a way that is human readable. According to the Fedora Draft Documentation OpenSSH Guide, “When using a network connection, essential and complex communication protocols such as TCP |Transmission Control Protocol| and UDP |User Datagram Protocol| take place mostly "behind-the-scenes" and are hidden beneath the user interface.” This is where plain text protocols are exposed and encrypted protocols are protected. A SSH tunnel can be configured in order to encrypt traffic on a specific port. # ssh -N -L |port-number|:|remote-machine-ip|:|remote-machine-port| [email protected]p Each user should have a .ssh directory in their home directory |~/.ssh|. A journal at linuxjournal.com explain that, “First, the client and the server exchange |public| host keys. If the client machine has never encountered a given public key before, both ssh and most web browsers ask the user whether to accept the untrusted key. Next, they use these to negotiate a session key that is used to encrypt all subsequent session data via a block cipher such as Triple-DES |3DES|, blowfish, or idea.” From the ~/.ssh location the following files are commonly used: id_rsa id_rsa.pub known_hosts The id_rsa file contains a users private key. You can use the cat command to read the file text and you will see that it is full of randomly generated characters. The private key for a user should not be shared with anyone else because if someone gets your private key then they can match it to the public key transmissions and read traffic encrypted with SSH intended for the other user. The id_rsa.pub key is the public key that is shared and used for public transmissions. The known_hosts file contains a list of host keys for all hosts that the user has logged into that are not already in the systemwide list of known host. Example OpenSSH Files for a Red Hat Enterprise Linux 6 system: The server package for allowing clients to connect to the system is openssh-server-* with the specific version number and architecture listed at the end. This package contains the SSH daemon which allows SSH clients to securely connect to the SSH server. The openssh-clients-* package includes the clients necessary to make encrypted connections to SSH servers. The libssh2-* package is a library implementing the SSH2 protocol. The openssh-* package includes the core files necessary for both the OpenSSH client and server. Heartbleed.

About Swift (from Wikipedia) Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of extant Objective-C (ObjC) code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C, and more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and, on platforms other than Linux, uses the Objective-C runtime library, which allows C, Objective-C, C++ and Swift code to run within one program. Swift supports the core concepts that made Objective-C flexible, notably dynamic dispatch, widespread late binding, extensible programming and similar features. These features also have well-known performance and safety trade-offs, which Swift was designed to address. For safety, Swift introduced a system that helps address common programming errors like null pointers, and introduced syntactic sugar to avoid the pyramid of doom that can result. For performance issues, Apple has invested considerable effort in aggressive optimization that can flatten out method calls and accessors to eliminate this overhead. More fundamentally, Swift has added the concept of protocol extensibility, an extensibility system that can be applied to types, structs and classes. Apple promotes this as a real change in programming paradigms they term "protocol-oriented programming". Swift was introduced at Apple's 2014 Worldwide Developers Conference (WWDC). It underwent an upgrade to version 1.2 during 2014 and a more major upgrade to Swift 2 at WWDC 2015. Initially, a proprietary language, version 2.2 was made open-source software and made available under Apache License 2.0 on December 3, 2015, for Apple's platforms and Linux. IBM announced its Swift Sandbox website, which allows developers to write Swift code in one pane and display output in another. A second free implementation of Swift that targets Cocoa, Microsoft's Common Language Infrastructure (.NET), and the Java and Android platform exists as part of the Elements Compiler from RemObjects Software.[20] Since the language is open-source, there are prospects of it being ported to the web.[21] Some web frameworks have already been developed, such as IBM's Kitura, Perfect[22][23] and Vapor. An official "Server APIs" work group has also been started by Apple,[24] with members of the Swift developer community playing a central role.

Black Hat USA 2012 - Torturing OpenSSL
 
54:07
By: Valeria Bertacco For any computing system to be secure, both hardware and software have to be trusted. If the hardware layer in a secure system is compromised, not only it is possible to extract secret information about the software, but it is also extremely difficult for the software to detect that an attack is underway. This talk will detail a complete end-to-end security attack to on a microprocessor system and will demonstrate how hardware vulnerabilities can be exploited to target systems that are software-secure. Specifically, we present a side-channel attack to the RSA signature algorithm by leveraging transient hardware faults at the server. Faults may be induced via voltage-supply variation, temperature variation, injection of single-event faults, etc. When affected by faults, the server produces erroneous RSA signatures, which it returns to the client. Once a sufficient number of erroneously signed messages is collected at the client end, we filter those that can leak private key information and we use them to extract the private key. We developed an algorithm to extract the private RSA key from messages affected by single-bit faults in the multiplication during Fixed Window Exponentiation (FWE), that is, the standard exponentiation algorithm used in OpenSSL during RSA signing. Our algorithm was inspired by a solution developed by Boneh, et al. for the Chinese Remainder Theorem (CRT) [D. Boneh, R. DeMillo, and R. Lipton. On the importance of eliminating errors in cryptographic computations. Journal of Cryptology, Dec 2001], an algorithm particularly prone to attacks. Depending of the window size used in the encryption algorithm, it is possible to extract 4-6 bits of the private key from an erroneously signed message. Our attack is perpetrated using a FPGA platform implementing a SPARC-based microprocessor running unmodified Linux and the OpenSSL authentication library. The server provides 1024-bits RSA authentication to a client we control via Ethernet connection. Faults are injected by inducing variations in the supply voltage on the FPGA platform or by subjecting the server to high temperatures. Our client collects a few thousands signed messages, which we transfer to an 80-machines computing pool to compute the private RSA key in less than 100 hours. Note that our attack does not require access to the victim system's internal components, but simply proximity to it. Moreover, it is conceivable that an attack leveraging solely high temperatures can be carried out on machines in a remote poorly-conditioned server room. Finally, the attack does not leave any trail of the attack in the victim machine, and thus it cannot be detected. The presentation includes a live demo of the attack on an FPGA platform implementing a SPARC system. The system is powered via a voltage controller, used to induce variations in the supply voltage. The server is simplified to use a 128-bits private key so that the attack can be perpetrated during the briefing.
