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: 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

DeepSec 2019 Talk: New Tales of Wireless Input Devices – Matthias Deeg

Sanna/ September 13, 2019/ Conference

You can’t do much with computer without input devices. Microphones do not count, yet. This leaves the classic selection of human input. How secure are these devices? Did you ever wonder when typing, moving the mouse pointer, or attaching a presenting tool? Well, your questions will be answered at DeepSec 2019. Matthias Deeg will hold a talk where new security tales of wireless input devices like mice, keyboards, presenters, and barcode scanners using different 2.4 GHz radio-based communication technologies will be presented that have been collected over the last two years. Furthermore, SySS IT Security expert Matthias will present answers to unanswered questions of his previous wireless desktop set research and raise the awareness of security issues and practical attacks against vulnerable wireless input devices.   Matthias is interested in information technology – especially

DeepSec 2019 Talk: Lauschgerät – Gets in the Way of Your Victim’s Traffic and Out of Yours – Adrian Vollmer

Sanna/ September 11, 2019/ Conference, Security

The talk will present a new tool for pentesters called „Lauschgerät“. This python script acts as a convenient man-in-the-middle tool to sniff traffic, terminate TLS encryption, host malicious services and bypass 802.1X – provided you have physical access to the victim machine, or at least its network cable. There are three ways to run it: Either on its own dedicated device like a Raspberry Pi or Banana Pi, in a virtual machine with two physical USB-NICs attached, or on your regular pentest system in its own network namespace. It will look like a completely transparent piece of wire to both victim systems you are getting in the middle of, even if they are using 802.1X because it is implementing the ideas presented in a talk by Alva Lease ‘Skip’ Duckwall IV. The Lauschgerät operates

Industrial Espionage and Data Tapping are commonplace in IT – DeepSec Conference provides Training for early Detection, Analysis and Mitigation

Sanna/ September 10, 2019/ Conference, Security

The excitement used to be great when organizations, parties, celebrities, companies, or government agencies reported intrusions into their own or outsourced digital infrastructure. Meanwhile, reports of data leaks and compromised systems are almost a part of the weather forecast. Security applications on smartphones or portals offer this information to allow the user to check if they might be affected too. The networked world of everyday life makes it seemingly possible to present attack and defence in the same breath. Affected, attackers, defenders and beneficiaries move closer together. But anyone who has this impression has fallen victim to the looming simplification. Modern information technology has to deal with dangerous situations every day that have far more facets. This requires a good deal of specialist knowledge and experience. First Responders, Analysis and Detection of Threats All

DeepSec 2019 Talk: Once upon a Time in the West – A Story on DNS Attacks – Valentina Palacín, Ruth Esmeralda Barbacil

Sanna/ September 9, 2019/ Conference

The Internet is the new frontier for some. So just like in Old West movies, we are going through a land riddled with well-known gunmen: OceanLotus, DNSpionage and OilRig, who roam at ease, while the security cowboys sleep. This presentation will uncover the toolset and techniques used by these gunmen, taking a closer look at their big guns and their behavioral patterns. We will explore the attacks involving DNS that took place during the last decade to examine the latest discovered techniques in order to improve detections to dodge the bullets they are firing in our direction. We asked Valentina and Ruth a few more questions about their talk at the DeepSec conference. Please note that Valentine and Ruth will also speak the the DeepINTEL conference where you will get more in-depth information not

DeepSec Press Release: Internet of Facts and Fear in the Name of IT Security – Bits, Bytes, Security and Geopolitics

Sanna/ September 5, 2019/ Conference, DeepIntel, Press, Schedule, Security, Security Intelligence

(Original press release was published on 29 August 2019 via pressetext.com) Nobody is an island. This statement is attributed to the English writer John Donne. The sentence became known in the 17th century. In the meantime, this has changed as a result of digitization. The modern version of the statement should read: There are no more islands. Increasing networking is reaching more and more areas of everyday life and society. So this year’s DeepSec In-Depth Security Conference wants to look soberly at the Internet of facts and fear from an information security perspective. Systems are currently less isolated and much more complex than the theory of information security technically allows. The DeepSec conference therefore dedicates its two days of conference and two days of training to current technologies and their vulnerabilities. At the same

DeepSec 2019 Talk: Well, That Escalated Quickly! – A Penetration Tester’s Approach to Windows Privilege Escalation – Khalil Bijjou

Sanna/ September 4, 2019/ Conference, Security

Since the early stages of operating systems, users and privileges were separated. Implemented security mechanisms prevent unauthorized access and usage of data and functions. These security mechanisms have been circumvented a number of times, which has led to steady improvements. Nevertheless, attackers find new vulnerabilities and security holes. Security experts often encounter Mirosoft® Windows endpoints or systems and gain low privileged access. To fully compromise the system, privileges have to be escalated. Windows contains a great number of security concepts and mechanisms. These render privilege escalation attacks difficult. Penetration testers should have a sound knowledge base about Windows components and security mechanisms in order to understand privilege escalation concepts profoundly and to apply them properly. Khalil’s presentation at DeepSec 2019 imparts knowledge on Windows required to understand privilege escalation attacks. It describes the most

DeepSec2019 Talk: SD-WAN Secure Communications Design and Vulnerabilities – Denis Kolegov

Sanna/ September 2, 2019/ Conference, Security

Hardening communication protocols against network attacks is hard. And yet a lot of products are available on the market that allow you to transport data and messages. Since virtualisation entered the world of technology all things software-definded (SD) have become popular. Denis Kolegov will explain at DeepSec 2019 what the state of affairs in terms of information security is. The SD-WAN New Hope project targets the security of SD-WAN (software defined wide area network) products. It was started in December 2017, when a customer decided to buy a very secure and well-known SD-WAN product from one of the Top 5 vendors and wanted us to perform threat modelling and a vulnerability assessment. We were doing that for 6 months and found out that the product was awful from a security perspective. It had multiple
