DeepSec 2019 Talk: Comparing GnuPG With Signal is like Comparing Apples with Smart Light Bulbs – Hans Freitag

Sanna/ October 28, 2019/ Conference, Security

GnuPG is not designed to be used only in E-Mail, it plays an important role in securing all sorts of mission critical data. In this talk I will show you applications of GnuPG that are not E-Mail or Instant Messaging. We asked Hans a few more questions about his talk. Please tell us the top 5 facts about your talk. GnuPG is free software that can be used to encrypt and sign data. Signal is not a free software but may be used to communicate with others. You can’t compare apples with pears. In German the term glowing pear is used for light bulb. My Key ID is: 1553A52AE25725279D8A499175E880E6DC59190F How did you come up with it? Was there something like an initial spark that set your mind on creating this talk? I browsed the

DeepSec 2019 Training: Threat Hunting with OSSEC – Xavier Mertens

Sanna/ October 26, 2019/ Training

OSSEC is sometimes described as a low-cost log management solution but it has many interesting features which, when combined with external sources of information, may help in hunting for suspicious activity occurring on your servers and end-points. During this training, you will learn the basic of OSSEC and its components, how to deploy it and quickly get results. The second part will focus on the deployment of specific rules to catch suspicious activities. From an input point of view, we will see how easy it is to learn new log formats to increase the detection scope and, from an output point of view, how we can generate alerts by interconnecting OSSEC with other tools like MISP, TheHive or an ELK Stack / Splunk / … and add more contextual content with OSINT feeds. We

DeepSec 2019 Training: Pentesting Industrial Control Systems – Arnaud Soullie

Sanna/ October 25, 2019/ Training

In this intense two day training at DeepSec, you will learn everything you need to start pentesting Industrial Control Networks [also called Industrial Control Systems (ICS)]. We will cover the basics to help you understand what are the most common ICS vulnerabilities. We will then spend some time learning and exploiting Windows & Active Directory weaknesses, as most ICS are controlled by Windows systems. And we will cover the most common ICS protocols (Modbus, S7, Profinet, Ethernet/IP, DNP3, OPC…), analyze packet captures and learn how to use these protocols to talk to Programmable Logic Controllers (PLCs). You will learn how to program a PLC, to better understand how to exploit them. The training will end with an afternoon dedicated to a challenging hands-on exercise: The first [Capture The Flag] CTF in which you capture

Threats and Solutions for Supply Chain Attacks in IT – DeepSec conference sheds light on the concatenated logistics of information technology.

Sanna/ October 25, 2019/ Conference

On the web you can find videos of very sophisticated constructions of many dominoes. If you knock over one domino, a whole cascade of breathtaking actions follows. The domino effect in your own IT infrastructure is much less entertaining. Even there, everything usually begins harmlessly with a small action – reading a message, forwarding a document, accessing a web server or receiving a short message from a supposed employee. It becomes particularly exciting when the dominoes are your own suppliers and business partners. This year’s DeepSec Security Conference offers rich content to analyze the interwoven situation of today’s companies and organizations. In networks you need to trust In theory, there is always an outside and an inside. Doors, network filters, access, …. Data management knows this approach. In all IT architectures, therefore, a division

L’Internet des faits et la peur dans la sécurité informatique – Les conférences DeepSec et DeepINTEL dévoilent leurs programmes – bits, bytes, sécurité et géopolitique

Sanna/ October 17, 2019/ Conference, DeepIntel

« No man is an island ». Cette citation (« Aucun homme n’est une île ») est de l’écrivain anglais John Donne. Si la phrase est devenue célèbre au XVIIe siècle, elle prend un tout autre sens à l’ère du numérique. La version moderne serait plutôt : il n’y a plus aucune île. De plus en plus de domaines du quotidien et de la société sont connectés. Cette année, les conférences sur la sécurité DeepSec et DeepINTEL souhaitent donc jeter un regard sobre sur l’Internet des faits et sur la peur sous l’angle de la sécurité de l’information. Actuellement, les systèmes sont moins isolés et bien plus complexes que ce qui est raisonnable du point de vue de la sécurité. La DeepSec se consacre donc aux nouvelles technologies et à leurs vulnérabilités au cours de deux journées de conférences

DeepSec 2019 Talk: What’s Wrong with WebSocket APIs? Unveiling Vulnerabilities in WebSocket APIs – Mikhail Egorov

Sanna/ October 16, 2019/ Conference, Security

WebSocket protocol is many times more efficient than HTTP. In recent years we can observe that developers tend to implement functionality in the form of WebSocket APIs instead of traditional REST APIs, that use HTTP. Modern technologies and frameworks simplify the building of efficient WebSocket APIs. We can name GraphQL subscriptions or Websocket APIs supported in Amazon API Gateway. WebSockets APIs have a different security model compared to REST APIs, resulting in unique attack vectors. Nevertheless, developers rarely take them into account. WebSockets in browsers do not use the same-origin policy (SOP) concept, their security model is based on origin check. Out-of-the-box WebSockets provide no authentication and authorization mechanisms. WebSocket protocol is stateful and has two main phases: A handshake and data transfer phase. Most of the time authentication and authorization logic is implemented

DeepSec 2019 Talk: “The Daily Malware Grind” – Looking Beyond the Cybers – Tim Berghoff, Hauke Gierow

Sanna/ October 8, 2019/ Conference

Given the noise generated around all the “sexy” and no doubt interesting topics like 0days, APT, and nation state-sponsored threat actors it is easy to miss what is really going on out there, in the world of Joe Average. Actual telemetry data paints a picture that is in many respects different from what happens in a lot of the news coverage. Much of the malware out there, including some that is attributed to some sort of APT, is nowhere near anything that might be considered “sophisticated”. In this talk we will shine a light on different aspects of the realities of home users as well as companies, and offer some interesting data about the malware that actually does the most damage, while precious few get all the press. We asked Tim and Hauke a

ROOTS 2019 Invited Talk: Please, Bias Me! – Pauline Bourmeau

Sanna/ October 1, 2019/ Conference, ROOTS

Anyone doing research, audits, code reviews, or development will most probably use her or his brain. Have you ever considered what can influence your decisions and thinking processes? We asked Pauline Bourmeau to explain and to share her thoughts on this matter. Cognitive bias influences our decisions and affects many part of our daily life. We will explore how it affects our security responses, and how we can identify it and be more effective. From Red-team to Forensic experts to incident responders, we see what we expect to encounter in our field, based on our range of past experiences. Adversary tactics make gold out of these loopholes in our predictable thinking. This talk aims to invite the audience to step back from our daily routine and challenges us to understand what cognitive bias is.

DeepSec 2019 Talk: What Has Data Science Got To Do With It? – Thordis Thorsteins

Sanna/ September 26, 2019/ Conference, Security

In this talk I want to shed some light on data science’s place within security. You can expect to learn how to see through common data science jargon that’s used in the industry, as well as to get a high level understanding of what’s happening behind the scenes when data science is successfully applied to solve complex security problems. The talk is aimed at anyone who’s been curious or had questions about the rise of things like “machine learning” or “big data” in the context of security. No prior data science knowledge is required. We asked Thordis a few more questions about her talk which will be held at DeepSec 2019. Please tell us the top 5 facts about your talk. It will give an insight into the exciting (and sometimes terrifying) world

DeepSec 2019 Talk: Techniques and Tools for Becoming an Intelligence Operator – Robert Sell

Sanna/ September 23, 2019/ Conference, Security Intelligence

In this talk at DeepSec 2019, Robert will introduce the various operations that Trace Labs has performed to help illustrate Open-Source Intelligence (OSINT) techniques used in finding details on real human subjects. Trace Labs is a non-profit organization that crowdsources open source intelligence to help law enforcement find missing persons. Trace Labs is non-theoretical and its members are conducting OSINT on real people. Robert lifts the curtain on successful OSINT techniques that can be used to pull up important information on individuals. Many of the slides show specific tools and techniques that can immediately be used to improve your OSINT results. The talk starts with a brief introduction to Trace Labs and its mission of helping law enforcement through a crowdsourced, open source intelligence. It then moves into a technical discussion on how to

DeepSec 2019 Talk: The Turtle Gone Ninja – Investigation of an Unusual Crypto-Mining Campaign – Ophir Harpaz

Sanna/ September 20, 2019/ Conference, Security

Despite the absence of blockchain and „crypto“ at DeepSec we have some content which covers security incidents connected to both terms. Ophir Harpaz will present her insights into an attack that is used to do „crypto“ mining. She describes what to expect in her own words: At first sight, Nansh0u is yet another attack campaign aiming to mine a marginal crypto-currency named TurtleCoin. However, things get much more interesting once you gain full access to the attacker’s infrastructure. Our investigation revealed a complete picture of how the Nansh0u campaign operates, who the infected victims are and what advanced tools are used in the attacks. Port scanner, brute-force module, remote-code execution tool, verbose log files and tens of different malware payloads – these are only a portion of the attacker’s assets we managed to put

DeepSec 2019 Training: IoT/Embedded Development – Attack and Defense Lior Yaari

Sanna/ September 19, 2019/ Training

Every developer makes mistakes. If you are unlucky, these mistakes result in a security vulnerability, an almost untraceable bug for the normal developer. Going around the world, helping developers to find and understand the vulnerabilities they’ve accidentally created, we learned that unlike bugs, vulnerabilities are invisible to the eye, mind and UT. No one teaches developers how an attacker thinks, what computers security mechanisms are capable of (and what not), and how to avoid creating possible security mistakes endangering your customers. In this course we will teach you the basics of Embedded Devices security from the beginning: How vulnerabilities are created and how an attacker approaches a new device. From the internals, – physical manipulations, buffer overflows, memory corruptions, timing attacks, all the way to the solution: How to avoid common mistakes and even
