DeepSec 2016 Talk: CSP Is Dead, Long Live Strict CSP! – Lukas Weichselbaum

Sanna/ September 8, 2016/ Conference

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

DeepSec2016 Talk: badGPO – Using GPOs for Persistence and Lateral Movement – Yves Kraft & Immanuel Willi

Sanna/ September 7, 2016/ Conference, Development, Security

System administration has evolved a lot during the past decades. Instead of enjoying long walks through the forests of servers and clients, the modern sysadmin controls the whole infrastructure by policies. Most operating systems can take advantage of this technology. As with software upgrades, these tools can make your life easier – or help an intruder to get a firm hold onto your infrastructure. Malicious activity can exploit your management networks/systems. Once this happens, you are in deep trouble. We have invited two security experts who created a demonstration. They used the Microsoft® Windows platform in combination with native tools: Group Policy is a feature which provides centralized management and configuration functions for the Microsoft operating system, application, and user settings. Group Policy is simply the easiest way to reach out and configure computer

DeepSec 2016 Talk: Machine Duping – Pwning Deep Learning Systems – Clarence Chio

Sanna/ September 6, 2016/ Conference, Security

Give a man a computer, and you 0wn him for a day. Teach a man to employ machine learning, and he will have to battle Skynet for a lifetime. This quote might not be the exact copy of the original, but it will do. Machine now learn stuff. Hence the are of machine learning is the new playground for start-ups, old school companies, researchers, and hackers, of course. A new era of sapiosexual attraction to artificial minds has begun. Information security is not spared. Algorithms have long been a part of defence. Now they are being used with machine learning. Since algorithms and machines run on networked computers, they can be attacked. At DeepSec 2016 Clarence Chio will explain to you how it can be done. Deep learning and neural networks have gained incredible

Deep Sec2016 Talk: DROWN – Breaking TLS using SSLv2 – Nimrod Aviram

Sanna/ September 5, 2016/ Conference, Internet

In the past years encrypted communication has been subject to intense scrutiny by researchers. With the advent of Transport Layer Security (TLS) Internet communication via HTTP became a lot more secure. Its predecessor Secure Sockets Layer (SSL) must not be used any more. The real world has its own ideas. SSLv2 and SSLv3 is still present. Attackers can try to downgrade the TLS session by switching to insecure ciphers. When using the correct configuration, these downgrade attacks cannot happen. The question is: Are all of your devices, applications, and systems correctly configure? If you are not sure, better check again. In order to illustrate how these attacks work, we have invited Nimrod Aviram for DeepSec 2016. He will explain the inner workings of the DROWN attack. We present a novel cross-protocol attack on TLS

DeepSec2016 Workshop: Offensive iOS Exploitation – Marco Lancini

Sanna/ September 4, 2016/ Conference, Training

If an iPhone gets exploited in the forest and no one is around to 0wn it, does it worry you? This philosophical question has been answered sufficiently by the latest Pegasus incident. All smartphone should worry you. The iPhone and its operating system is no exception. Actually breaking a smartphone give an attacker a lot of advantages. Chances are that you carry the exploited device with you all the time. At last the Age of Mobility has reached information security! In order to develop exploits you need a healthy dose of software development and a (deep) knowledge of the platform being attacked. For those of you who do a lot of penetratoion testing, security analysis, or plain software quality management, we have a shortcut for you: the iOS exploitation workshop. This is an exercise-driven

DeepSec 2016 Workshop: Penetration Testing Humans – Bethany Ward & Cyni Winegard

Sanna/ September 3, 2016/ Conference, Security, Training

Do you know the film where the victim gets an unsuspecting phone call and dies three days later? No? Relax, it happens in the real world, too. The difference is that you get a quite normal phone call at the office and three days later some of your data has been copied. The technical term is leaked, also known as stolen. All your security measures will be untouched. Why break into a firewall or into servers when you get the access credentials by phone? Social engineering is an advanced and very persistent threat. You probably get phone calls and emails every day. You may often interact with people you have never seen or met before. Given the right approach they will make you and your employees believe anything. In turn this technique is very

Thoughts on Lawful Malicious Software and its Impact on IT Infrastructure

Sanna/ April 14, 2016/ Interview, Press, Security

During the premiere of „A Good American“ we had a chat with journalists. Markus Sulzbacher of Der Standard wanted to know what the implication of the so-called Bundestrojaner (litterally federal trojan, the colloquial German term for the concept of inserting government malware in order to extract information from a suspect’s computer and telephone devices). The idea is to infect a computer system with malicious software that sits in the background and to siphon off the hard-to-get data connected to communication (i.e. messengers, Skype, emails, etc.). We have translated the interview from German to English for you. You can find the original on Der Standard web site. Der Standard 12.04.2016 “The federal Trojan is governmental malware” Police praise the software as a “wonder weapon against terror”. But for IT expert René Pfeiffer the planned introduction

Endangered Species: Full Disclosure in Information Security

Sanna/ November 6, 2015/ Discussion, High Entropy, Legal, Security

History, fictive or real, is full of situations where doubts meet claims. Nearly every invention, every product will be eyed critically, analysed, and tested. There are even whole magazines fully dedicated to this sport, be it for example, consumer protection, reviews of computer games or the car of the year. When it comes to testing the sector of information security is particularly sensitive. Depending on the hard- or software concerned, testing is not only about comfort or in search of a particularly good storyline, but about incidents, which can cause real damage in the real world. How should one deal with the knowledge of a design flaw affecting the security of a system? Locks In 1851 the American lock-smith Alfred Charles Hobbs visited the Great Exhibition in London. He was the first to pick

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: Bridging the Air-Gap: Data Exfiltration from Air-Gap Networks – Mordechai Guri & Yisroel Mirsky

Sanna/ November 4, 2015/ Conference, Internet, Security

Air does not conduct electricity, usually. Using air gaps between parts transporting electric power by high voltages is a standard method in electrical engineering. Similar strategies are used in information security. Compartmentalisation can be done by network components, logical/physical separation, solid walls, and space filled with air. The only threat you have to worry about are wireless transmissions. Since mobile phone networks permeate our private and business life, access to wireless networks is everywhere. Unless you live in a cave, literally. Mordechai Guri and Yisroel Mirsky have found a way to use cellular frequencies as a carrier in order to transport data out of an air-gapped environment. They will present their results at DeepSec 2015. Air-gapped networks are isolated, separated both logically and physically from public networks. Although the feasibility of invading such systems

DeepSec 2015 Talk: A Death in Athens: The inherent Vulnerability of “lawful Intercept” Programs, and Why all Government authorized Backdoors are very dangerous – James Bamford

Sanna/ October 22, 2015/ Conference, Security Intelligence

Some of you might remember the „Athens Affair“. In 2005 Ericsson found backdoors in the lawful interception systems of Vodafone Greece. The software on these modules was altered to successfully wiretap phone numbers without detection. When one of the tapped phones made or received a phone call, the exchange, or switch, sent a duplication of the conversation to one of fourteen anonymous prepaid mobile phones. The incident sparked an investigation, and Vodafone Greece was fined millions of Euros for breaching privacy laws. In February 2015 the Greek authorities issued a warrant for a suspect linked to the NSA. Lawful interception (LI) capabilities are mandatory for telecommunication equipment. In Europe the technical requirements and standards are developed by the European Telecommunications Standards Institute (ETSI); the 3rd Generation Partnership Project (3GPP) maintains the part relevant for

DeepSec 2015 Talk: Agile Security – The Good, The Bad, and mostly the Ugly – Daniel Liber

Sanna/ October 14, 2015/ Conference, Security

Particle collisions are a rich source for insights into the inner workings of Nature. Physicists know this. The Large Hadron Collider (LHC) built by the European Organization for Nuclear Research (CERN) demonstrates this to the extreme. You can to the same in information security if you lock developers and security experts into a room. Acceleration can be achieved by asking for the best way for implementing security. Analyse the high energetic trails of heated arguments to gain new insights. This recipe works best with certain models of software development. David Liber will show you the results of the collisions and tell you what you can learn about security with a specific software development methodology. Moving away from Waterfall and traditional development processes towards Agile methodologies has become more and more popular recently. Talking about sprints, looking
