Clear guidelines for events and conferences slowly emerge here in Austria. We have some news on how DeepSec, DeepINTEL, and ROOTS will look like in November. We will compile the set of regulations in a separate document and publish it on our web site. The constraints set by the authorities contain no show-stoppers for the event and the trainings. We will carefully work out a concept which we will use in November for everything that is going on on site in Vienna. 😷 We have the full support of our conference hotel, and we are confident that we can increase health protection and decrease risks for everyone attending. In addition we found some bug in the ticket shop system. The tickets for DeepINTEL, DeepSec conference / training, and ROOTS can be bought via the
DeepSec Training: Black Belt Pentesting / Bug Hunting Millionaire – Mastering Web Attacks with Full-Stack Exploitation
Web applications are gateways for users and attackers alike. Web technology is used to grant access to information, public and sensitive alike. The latest example is the Biostar 2 software, a web-based biometric security smart lock platform application. During a security test the auditors were able to access over 1 million fingerprint records, as well as facial recognition information. How can you defend against leaks like this? Well, you have to understand all layers of the application stack. Modern web applications are complex and it’s all about full-stack nowadays. That’s why you need to dive into full-stack exploitation if you want to master web attacks and maximize your payouts. Say no to classic web application hacking. Join the training session at DeepSec 2019 and take advantage of Dawid Czagan’s unique hands-on exercises and become
DeepSec 2018 Talk: Leveraging Endpoints to Boost Incident Response Capabilities – Francisco Galian, Mauro Silva
The information technology world is full of terms and acronyms. You got servers, nodes, clients, workstations, mobile devices, lots of stuff talking via the network to even more stuff. And then you got security breaches. How do you detect the latter? Well, you look for things out of the ordinary. Error messages, anomalies in behaviour, activity outside the usual time slots as system is being used, and the like. What’s the best place to look? Answer: The systems directly in touch with all the interactions attackers are interested in – endpoints. Most organisations fail to properly detect or even respond to incidents. A factor that significantly contributes to this fact is the lack of visibility on endpoints. That being said, endpoint logging can be very noisy and most organizations don’t have infrastructure to cope
DeepSec 2017 Talk: How To Hide Your Browser 0-days: Free Offense And Defense Tips Included – Zoltan Balazs
There is a famous thought experiment described in the book A Treatise Concerning the Principles of Human Knowledge. It deals with the possibility of unperceived existence; for example does a falling tree in the forest make a sound when no one is around to hear it? Given the many reports and mentions about zero-day exploits, the question might be rephrased. Does a zero-day exploit cause any effects when no one is able to detect its presence? Before we completely get lost in philosophy, the question has a real background. Zoltan Balazs wants to address the issue of zero-days in his DeepSec 2017 presentation. The idea seems somewhat contrary to intuition – protecting exploits from being disclosed. Zero-day exploits targeting browsers are usually very short-lived. These zero-days are actively gathered and analyzed by security researchers.
DeepSec 2017 Talk: Essential Infrastructure Interdependencies: Would We Be Prepared For Significant Interruptions? – Herbert Saurugg
How would your day look without electrical power? Given the fact that we rely on information technology every single minute of our lives (well, mostly), this would be a very dark outlook indeed. Knocking out the power grid is a tactic used by the military. They have even special tools for disabling power lines and transformer stations. Progress has enabled network access for power plants and other parts of the grid. It’s not all about hacking stuff. There is a lot more involved when it comes to critical infrastructure, and this is why we have asked Herbert Saurugg, a renowned specialist on this topic, to conduct a presentation at DeepSec 2017. Cyber Security and Critical Infrastructure Protection (CIP) are major topics almost everywhere. Its priority has also increased during recent years because of rising
The information security world is full of buzzwords. This fact is partly due to the relationship with information technology. No trend goes without the right amount of acronyms and leetspeaktechnobabble. For many decades this was not a problem. A while ago the Internet entered mainstream. Everyone is online. The digital world is highly connected. Terms such as cyber, exploit, (D)DoS, or encryption are used freely in news items. Unfortunately they get mixed up with words from earlier decades leading to cyber war(fare), crypto ransom(ware), dual use, or digital assets. Some phrases are here to stay. So let’s talk about the infamous cyber again. In case you have not seen Zero Days by Alex Gibney, then go and watch it. It is a comprehensive documentary about the Stuxnet malware and elements of modern warfare (i.e.
The Deutsche Telekom was in the news. The reason was a major malfunction of routers at the end of the last mile. Or something like that. As always theories and wild assumptions are the first wave. Apparently a modified Mirai botnet tried to gain access to routers in order to install malicious software. The attacks lasted from Sunday to Monday and affected over 900,000 customers. These routers often are the first point of contact when it comes to a leased line. Firewalls and other security equipment usually comes after the first contact with the router. There are even management ports available, provided the ISP has no filters in place. The TR-069 (Technical Report 069) specification is one management interface, and it has its security risks. Now that the dust has settled the Deutsche Telekom
DeepSec2016: 0patch – Self-healing Security Updates. DeepSec and ACROS Security Introduce a Platform for Micropatches
As soon as a security gap in an computer application is made public the anxious wait begins. Whether it is software for your own network, online applications or apps for your mobile devices, as a user you will quickly become aware of your own vulnerability. The nervousness increases. When will the vendor publish the security update? In the meanwhile is there anything you can do to reduce the risks? Alternatively, how long can you manage without this certain software? To provide answers to these questions is the central point of security management. Some vendors have fixed dates for security updates. However, occasionally unscheduled updates take place, while some vendors wait quite a few years before they release another update. And this is only true for applications that are still in production or come with a support
DeepSec2016 Talk: AMSI: How Windows 10 Plans To Stop Script Based Attacks and How Good It Does That – Nikhil Mittal
In his talk Nikhil Mittal will focus on AMSI: In Windows 10, Microsoft introduced the AntiMalware Scan Interface (AMSI), which is designed to target script based attacks and malware. Script based attacks have been lethal for enterprise security and with the advent of PowerShell, such attacks have become increasingly common. AMSI targets malicious scripts written in PowerShell, VBScript, JScript, etc. It drastically improves detection and the blocking rate of malicious scripts. When a piece of code is submitted for execution to the scripting host, AMSI steps in and scans the code for malicious content. What makes AMSI effective is that no matter how obfuscated the code is, it needs to be presented to the script host in clear text and unobfuscated. Moreover, since the code is submitted to AMSI just before execution, it doesn’t
The Content Security Policy (CSP) is an additional layer of security for web applications. It is intended to detect and mitigate certain types of attacks. CSP is deployed by using the HTTP Content-Security-Policy header for publishing a policy. The policy instructs the web client how various resources will be used, where they come from, and the like. Violations of the policy can be reported to an application. Basically you can give the web client important hints what to expect. The reporting helps your intrusion detection process since the web clients usually understand the Web better than IDS modules. Lukas Weichselbaum is working at Google, and he will explain how CSP can be bypassed. In this presentation I’ll highlight the major roadblocks that make CSP deployment difficult. I talk about common mistakes, about how we automatically bypassed
The Call for Papers for the tenth DeepSec conference officially ends in 24 hours. This is a gentle reminder to submit your presentation or your kick-ass workshop.
Like the Force wireless data/infrastructure packets are all around us. Both have a light and a dark side. It all depends on your intentions. Lacking the midi-chlorians we have to rely on other sources to get a picture of the wireless forces in and around the (network) perimeter. At DeepSec 2015 Milan Gabor held a presentation about visualisation of wi-fi packets: Today visualizing Wi-Fi traffic is more or less limited to console windows and analyze different logs from an aircrack-ng toolset. There are some commercial tools, but if we want to stay in the Open/Free Source Code (FOSS) area we need to find better solutions. So we used ELK stack to gather, hold, index and visualize data and a modified version of an airodump tool for input. With this you can create amazing dashboards,
Testing the defences of a network, applications, or infrastructure can be tough. Often you spend lots of days, the results not being proportionate to the time spent. How do you assess success when doing penetration testing? How to test, what tools to use, and who should be doing the testing? Johnny Deutsch has some answers for you. He held a presentation at DeepSec 2015 about this topic. We recommend watching this presentation to everyone thinking about requesting a penetration test or, of course, everyone actually doing these tests.
Unfortunately the Internet doesn’t follow the rules of economic theory. Unlimited growth is a myth best kept for feeding your unicorns. Of course, the Internet has grown, but the mathematics and physics behind network flows stay the same. If your pipe is full, then you are going nowhere. This is why Distributed Denial of Service (DDoS) attacks still work. You can counter or evade these attacks, but they can happen. We invited Dave Lewis of Akamai to DeepSec 2015 to hear his view on the current state of affairs where DDoS is concerned. For the record: DDoS is not hacking and no hacking attack. Spread your „cyber“ somewhere else.
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.
