DeepSec 2016 Talk: Exploiting First Hop Protocols to Own the Network – Paul Coggin

Sanna/ October 16, 2016/ Conference, Internet, Security

At DeepSec 2016 Paul Coggin will focus on how to exploit a network by targeting the various first hop protocols. Attack vectors for crafting custom packets as well as a few of the available tools for layer 2 network protocols exploitation will be covered. Paul will provide you with defensive mitigations and recommendations for adding secure visualization and instrumentation for layer 2. He kindly answered a few questions beforehand: Please tell us the top facts about your talk. The presentation focuses on commonly overlooked layer 2 security issues. In many cases penetration testers and auditors focus on the upper layers of the OSI model and miss the low hanging fruit at layer 2. The talk will cover both offensive exploit techniques and methods for securing networks. Multicast switching and routing protocols, router redundancy protocols, IPv6 and other

Smart Homes are the battlefield of the future – DeepSec Conference examines the Internet of Things

Sanna/ October 14, 2016/ Conference, Internet, Press, Security, Veranstaltung

The Internet of Things is knocking at your door. Many businesses and private individuals have already admitted IoT to their offices and homes, unfortunately often without knowing what they’ve let themselves in for. A naive belief in progress opens all gates, doors and windows to attackers. This is a serious matter. Therefore, DeepSec Conference will focus on this topic on the occasion of its 10th anniversary. The program includes lectures and workshops about the components of smart devices, smart houses and smart networks. Not all products come with a solid security concept. How to test if your devices function properly? What consequences has the total conversion to “smart”? How to proceed correctly to select appropriate systems? Hacked by your fridge Spectacular burglaries have always been the best material for screenplays. We know the scene

DeepSec 2016 Workshop: Fundamentals of Routing and Switching from a Blue and Red Team Perspective – Paul Coggin

Sanna/ October 12, 2016/ Security, Training

Penetrating networks has never been easier. Given the network topology of most companies and organisations, security has been reduced to flat networks. There is an outside and an inside. If you are lucky there is an extra network for exposed services. Few departments have retained the skills to properly harden network equipment – and we haven’t even talked about the Internet of Things (IoT) catastrophe where anything is connected by all means necessary. Time to update your knowledge. Luckily we have just the right training for you! In Paul Coggins’ intense 2 day class, students will learn the fundamentals of routing and switching from a blue and red team perspective. Using hands-on labs they will receive practical experience with routing and switching technologies with a detailed discussion on how to attack and defend the network

DeepSec2016 Talk: The (In)Security or Sad State of Online Newspapers – Ashar Javed

Sanna/ October 8, 2016/ Conference, Internet, Press

Web sites are simply, one might think. The client requests a page, the server sends it, the layout is applied, and your article appears. This is a heavy simplification. It worked like this back in 1994. Modern web sites are much more complex. And complexity attracts curious minds. Usually that’s what gets you into trouble. Now content management systems serve the web page of the 1990s with a lot of queries, executable code, and from different servers. The ever changing Top 10 list of mistakes from the Open Web Application Security Project can show you the tip of the iceberg. Ashar Javed took a closer look at online newspapers, and he found some scary stuff. The goal of his talk is to raise awareness about the (in)securities of online newspapers. Ashar Javed hopes that their

DeepSec Video: Revisiting SOHO Router Attacks

René Pfeiffer/ March 1, 2016/ Conference, Security

Routers are everywhere. If you are connected to the Internet, your next router takes care of all packets. So basically your nearest router (or next hop as the packet girls and guys call them) is a prime target for attackers of any kind. Since hard-/software comes in various sizes, colours, and prices, there is a big difference in quality, i.e. how good your router can defend itself. Jose Antonio Rodriguez Garcia, Ivan Sanz de Castro, and Álvaro Folgado Rueda (independent IT security researchers) held a presentation about the security of small office/home office SOHO routers at DeepSec 2015. Domestic routers have lately been targeted by cybercrime due to the huge amount of well-known vulnerabilities which compromise their security. The purpose of our publication is to assess SOHO router security by auditing a sample of

DeepSec Video: HORNET – High-speed Onion Routing at the Network Layer

René Pfeiffer/ February 22, 2016/ Conference, Internet, Security

Given that reconnaissance is the first step of a successful attack, anonymity has become more important than ever. The Invisible Internet Project (I2P) and the TOR project are prominent tools to protect against prying eyes (five or more). TOR is widely used. Users of anonymity services will notice that the price for extra protection is less speed in terms of latency and probably bandwidth. Researchers have published a method to attain high-speed network performance, called HORNET. HORNET is designed as a low-latency onion routing system that operates at the network layer thus enabling a wide range of applications. Our system uses only symmetric cryptography for data forwarding yet requires no per-flow state on intermediate nodes. This design enables HORNET nodes to process anonymous traffic at over 93 Gb/s. At DeepSec 2015 Chen Chen explained

DeepSec Video: illusoryTLS – Nobody But Us. Impersonate,Tamper and Exploit

René Pfeiffer/ February 15, 2016/ Conference, Internet, Security

Cryptographic backdoors are a timely topic often debated as a government matter to legislate on. At the same time, they define a space that some entities might have practically explored for intelligence purposes, regardless of the policy framework. The Web Public Key Infrastructure (PKI) we daily rely on provides an appealing target for attack. The entire X.509 PKI security architecture falls apart if a single CA certificate with a secretly embedded backdoor enters the certificate store of trusting parties. Do we have sufficient assurance that this has not happened already? Alfonso De Gregorio presented at DeepSec 2015 his findings and introduced illusoryTLS. Aptly named illusoryTLS, the entry is an instance of the Young and Yung elliptic curve asymmetric backdoor in the RSA key generation. The backdoor targets a Certification Authority public-key certificate, imported in

Debugging Information Security: Self Defence for Entrepreneurs

Sanna/ November 5, 2015/ Conference, High Entropy, Internet, Security, Security Intelligence

In our economy data leaks are a constant companion. That’s the impression one gets when reading the news. Customer portals, online shops, digital communications, plans of products, personnel data, and more can be found in department stores throughout the shadow economy. Blind faith in global networks has indeed suffered in recent years, but companies and individuals still have a partially carefree attitude when it comes to the imminent risk their data is exposed to. “Who cares about our data?”, is often said. This year’s DeepSec IT Security Conference has some very specific answers to this question. Duncan Campbell and James Bamford open IT Security Conference in Vienna Duncan Campbell is a freelance British journalist, author, and television producer. Since 1975 he has specialized in intelligence and security services, defence, policing and civil liberty rights.

DeepSec 2015 Talk: Cryptography Tools, Identity Vectors for „Djihadists“ – Julie Gommes

René Pfeiffer/ September 30, 2015/ Conference, Security, Security Intelligence

Some speak of Crypto Wars 2.0. For others the Crypto Wars have never ended. FBI Directory James Comey does not get tired of demanding back doors to IT infrastructure and devices (there is no difference between back door and front door, mind you). Let’s take a step back and look at the threats. We did this in 2011 with a talk by Duncan Campbell titled How Terrorists Encrypt. The audience at DeepSec 2011 was informed that encryption does not play a major role in major terror plots. What about today? Have terrorists adopted new means of communication? Since the authorities demanding access to protected information do not have statistics readily available, we turned to researchers who might answer this question. Julie Gommes will present the results of studies analysing the communication culture of criminal

DeepSec 2013 Talk: Prism Break – The Value Of Online Identities

René Pfeiffer/ November 1, 2013/ Conference, Internet

We all have identities. We use them on a daily basis in our off-line world. Colleagues greet us at work, because they know who we are. Of course our family members know who we are. When it comes to the digital life-style our identity becomes a lot more complex and diverse. Web shops know what we like and suggest products we do not yet have. Social media sites suggest contacts that might match our interest (as do dating web sites). Frequently used search terms are processed to refine the results our favourite search engine presents us. Customisation and targeting is the key. Everything you do and communicate is processed like ore and the Big Data server farms refine your daily trails through the Internet and produce your online identity – which is a good

Talk/Workshop: IPv6 Security In-Depth

René Pfeiffer/ September 6, 2011/ Conference

The tale of two protocol suites has been being written for some time now. The IPv4 Internet has run out of fresh addresses. The IPv6 deployment has begun, but it will take some time before IPv4 is completely phased out (if ever). The work on the IPv6 protocol started in the early 1990s with the temporary IP Next Generation Working Group, collecting proposals. In theory IPv6 addresses many shortcomings of IPv4 and consists of a thoroughly well-designed protocol suite with security in mind. In practice you will neither just switch to IPv6 nor skip the step where you consider the security implications. There is no zero conf mechanism when it comes to security. All businesses need to know what the security impact of IPv6 really is. Some networks have already deployed IPv6, others think
