This talk was presented at OWASP London Chapter Meeting on 18-May-2017. Slides can be downloaded here: https://www.owasp.org/images/9/9e/DrGFragkos-ThreatModeling-PaymentSystems-OWASP-2017-May-18.pdf Payment systems are part of our everyday lives, with most of the transactions performed through the use of a Point-of-Interaction (POI) device or a Virtual Terminal. Although payment terminals and virtual terminals make use of strong encryption and a secure communications channel, the Point of Sale (POS) is still a target for cyber-criminals. The malware affecting point-of-sale systems seen in previous years has demonstrated that criminals continually adapt to find ways to target card payment channels and keep the cycle going. This presentation however, attempts to go a step further and asses payment systems from a hypothetical attacker's point of view, by undertaking at threat modeling exercise against payment systems. The purpose of the threat modeling is to provide defenders with a number of scenarios (attack vectors) that it is possible to be used by attackers, while their activity remain unnoticed. One of the most important lessons of this Threat Modeling exercise was the discovery of a potential scenario that could allow cyber-criminals to shift from targeting Card Holder Data (CHD) to targeting the money directly. Speaker Bio: Dr. Grigorios Fragkos is the Head of Offensive Cybersecurity for DeepRecce(invinsec). He has a number of publications in the area of Computer Security and Computer Forensics with active research in CyberSecurity and CyberDefence. His R&D background in Information Security, including studies on applied CyberSecurity at MIT, along with his experience in the CyberDefense department of the Greek military, is invaluable when it comes to safeguarding mission critical infrastructures. Written the next generation SIEM as part of his PhD research with “notional understanding” of network event for real-time threat assessment. Grigorios (a.k.a. Greg) has been invited to present in a number of security conferences, workshops and summits over the years, and he is also the main organiser for Security BSides Athens. Thinking ahead and outside-the-box when dealing with information security challenges is one the key characteristics of his talks.

After we've released a first commercial payment card with dynamic cvv code presented on e-ink paper on the bottom of the card there was so much inaccurate comments from the tech people in the social websites that I was scared and at the same time frustrated. People I know, who are the good developers or projects managers simply do not understand the basis of payment cryptographical flows. I was almost screaming that "cvv code is not just random digits! It's cryptographical signature of your card and it is never ever stored or represented on anything except your card and to verify it a super secure hardware called HSM needs to be used to recompute it and decide if the input made by a user in a web browser is the correct one!" Then I've realised that in fact if not for the project I was involved in last year my knowledge would be more or less the same: inaccurate and based on the wrong assumptions. When I looked around for the reasons why there is so much gap between people’s knowledge and real security patterns that are used in payment industry I've found a very simple explanation. There is simply not enough accessible and well presented information about payment cryptography and security measures. There is only highly advanced stuff with more mathematics than text or it is inaccessible due to the necessity of having to be part of payment organisations such as Visa or Security Council. My talk is aiming to fill this gap by introducing the audience to most popular machinery involved in making our world secure enough to trust the credit or debit card. I would like to present: * basis of symmetric cryptography algorithms * key derivation and why it so important for payment protection * how pin flows from ATM to issuer bank in order to be verified * what is HSM and why it is used * one more real world example with online payment transactions * how to tie it all together with PA-DSS certification As a practical bonus I would also like to show some java implementations of those algorithms and contrast it with how integration with the hardware crypto-modules looks like.

Understanding ARM HW Debug Options - Michael E. Anderson, The PTR Group Hardware-based debuggers are a staple in the embedded Linux world. However, the ARM architecture supports several different flavors of hardware debugging including JTAG, SWD, SWO, CMSIS-DAP and more. What are the features of these debugger interfaces and how can you use them to debug low-level code such as drivers in the Linux kernel? In this session, we will describe each of these interfaces and how they are used with a live demonstration of OpenOCD and its use to debug Linux kernel code. About Michael E Anderson Mike Anderson is currently CTO and Chief Scientist for The PTR Group, Inc. With over 39 years in the embedded and real-time computing industry, Mike works with a number of RTOS, Linux and Android-based devices in applications ranging from satellites and robotics to SCADA platforms. However, his focus over the past few years has been the use of Linux and Android in embedded sensor applications and the deployment of the Internet of Things.

To the power of x, you never seen it before, much less solved it, but you're like fo-sho, 'cause you have ideas that won't be denied. You take the xth root of both sides, but you're scratching your head, 'cause that didn't help, if the object is to get the x all by itself! You see, the only way to get that exponent down to earth, for what it's worth, there's nothing worse, and it is called inverse. In this case the Logarithm's your hearse, use Napier's curse to help you switch it around, And move that exponent a whole 6 feet underground. So use it, abuse it, apply it, remove it. Use it, abuse it, apply it, remove it. So why is it there - still? Looking down laughing, deriding while you're crying buckets over your spilled poten- -tial[shall] you stand this power drilling into your mind, Kinda like the fleeting feeling that you're dealing with π-ρ-technic visions of a exponential monster - unwind Untie[deride] the lies of your lofty tormentor, resent the disguise and embrace the inventor. Here's Johnny with a mantra that will cut to the center, as HE applies the inverse - exponential descenter. Clear your mind, lift the fog, The base of the power is the base of the log. Clear your mind, lift the fog, The base of the power is the base of the log. The base of the power is the base of the log. The base of the power is the base of the log. The base of the power is the base of the log. No more exponential messes for you, the essential message to you: Be the change you want to see, apply Logs to both sides of the equation that's distressing, and oppressing and depressing, and after all the messing, and the stressing, and the testing. I suppose logs are a blessing, but they maybe not the best thing.

The Drones Management System is the dispatcher system for the drones. The Civil Drones Management System allows: - To build 3D maps and the air highways for the delivery-drones/human transportation drones(taxi-drones, private transportation drones) - Manage the air-traffic - Monitor it and keep the safety with the help of the tactical anti-collision system - The so built air highway conforms the certain developed by airhighway.online driving rules based on the land vehicle rules and the air-traffic rules - The system is capable of generation the flight plan for the drones and the system does not use google map services for any purpose. - The system generates the number of the flight plans for the drones and selects the best one based on: the current air-traffic, technical characteristics of the drone, battery level and drone's priority. The Military AI Tactical System, working on military drones, has a purpose of taking autonomous tactical decisions based on Artificial Intelligence and performing them. The Civil Drones Management System consists of the following modules: Tactical Radar Server - responsible for receiving the data from the Radar(s) about the drones' positions , processing it and sharing among the whole system Permission Application Server - responsible processing the drone's requests: creation of the flight plans, responses to the tactical requests and collisions prevention management, etc. Monitoring System - responsible for monitring and management of the air highways, drones. The system also allows to send individual or group commands to the drones Database - responsible for keeping all the data (flight plans, movements) saved for the possible further use, such as: reports generation and investigations. The reports gets generated using MS Crystal Reports. There is an option allowing to switch between MS SQL Server and MongoDB databases. Client Drone Application - available in two releases: one of them is for the big drones responsible for human transprtation and another one is for the cargo-drones responsible for purchase's transportation. The first one contains user-friendly interface which serves as a communication layer between a drone and a human. The second one does not contain an interface because it's insalled on the cargo-drones only. The Client Drone Application communicates with the Tactical and Permission Servers using UDP network protocol. Radar Server - responsible for data communication among server located applications of the system Map Creator - responsible for creation of the 3D maps for the flight, consumed by drones. Allows to create 3D map of the region/city. All the communications are security protected and based on digital signatures using Elliptic Curves cryptography. The web site: http://airhighway.online

Pour pouvoir mener à bien des simulations sur des structures aléatoires, il est souhaitable de disposer d'une suite satisfaisant des propriétés a priori contradictoires: être aléatoire (pour que la simulation soit valide), et être engendrée par un processus déterministe, afin de pouvoir relancer son programme sur la même valeur pour le débugger par exemple. Nous verrons comment des travaux en cryptographie permettent de concilier ces deux objectifs a priori contradictoires en s'appuyant sur des conjectures d'informatique théoriques. Ces résultats reposent sur de jolies démonstrations mathématiques et d'intéressants arguments probabilistes que cet exposé passera en revue.

Google Tech Talks October 30, 2009 ABSTRACT Presented by Rob Pike What is Go? Go is a new experimental systems programming language intended to make software development fast. Our goal is that a major Google binary should be buildable in a few seconds on a single machine. The language is concurrent, garbage-collected, and requires explicit declaration of dependencies. Simple syntax and a clean type system support a number of programming styles. For more on Go including FAQs, source code, libraries, and tutorials, please see: http://golang.org
