DeepSec 2017 Talk: Malware Analysis: A Machine Learning Approach – Chiheb Chebbi

Sanna/ August 26, 2017/ Conference, Security

Software has a character. It can be beneficial. It can also be malicious. A networked business world and the Internet of connected individuals make life for malicious software, also known as malware, easier. Just like international travel facilitates the spread of diseases and parasites, the networked globe is a big advantage for malware. Researcher can hardly keep up with the numbers of detected viruses, worms, and trojan horses. So why not let machines look for malware on their own? Certainly automation already benefits the hunt for malicious code. Chiheb Chebbi has some ideas that can help. Threats are a growing problem for people and organizations across the globe. With millions of malicious programs in the wild it has become hard to detect zero-day attacks and polymorphic viruses.This is why the need for machine learning-based

DeepSec 2017 Keynote: Social Science First! – Dr. Jessica Barker

Sanna/ August 24, 2017/ Conference, High Entropy, Security

While the schedule is still preliminary, we have already some confirmations from our speakers. We are happy to announce Dr Jessica Barker as the keynote speaker for DeepSec 2017. Information security has a lot to do with interactions. Despite AI (a.k.a. Assisted Intelligence), „smart“ assistants (a.k.a. paper clips on steroids), and a metric ton of gadgets we still have a lot of contact with human beings. Marketing departments and tech people lost in code often forget this. Jessica will give you something to think about which you can’t discuss with Siri, Alexa, the Google AI, or even HAL 9000. Bruce Schneier popularised the concept in 1999: cyber security is about people, process and technology. Yet almost two decades later, the industry still focuses so much more on technology than the other two dimensions of

DeepSec 2017 Preliminary Schedule published

René Pfeiffer/ August 17, 2017/ Administrivia, Conference, Training

After two weeks of intense reviewing we have published the preliminary schedule for DeepSec 2017. There are some blanks to fill, but this will be done in the coming weeks. We still have to do some reviews and wait for the speaker’s confirmation. In case you noticed, the ROOTS track is not filled yet. The call for papers was extended to 26 August. This means the ROOTS schedule will be published at the end of September. We have to give the programme committee ample time to review all submissions. So if you want to present your research at ROOTS 2017, please ready your submission. Science first!

DeepSec 2016 – expect 48 Hours of Failures and Fixes in Information Security

René Pfeiffer/ November 10, 2016/ Conference, Discussion

The conference part of DeepSec 2016 has officially started. During the workshops we already discussed a lot of challenges (to phrase it lightly) for infrastructure and all kinds of software alike. The Internet of Things (IoT) has only delivered major flaws and gigantic Distributed Denial of Service attacks so far. There is even a worm for LEDs these days. And we haven started the conference preparations yet. So we have plenty of reasons to talk about what went wrong, what will go wrong, and what we can do about it. The world of information security is not always about good news. Something has to break, before it can be repaired – usually. Systems administrators know this, for some it’s their daily routine. Nevertheless we hope everyone at DeepSec gets some new insights, fresh ideas,

DeepSec 2016 Talk: Obfuscated Financial Fraud Android Malware: Detection And Behavior Tracking – Inseung Yang

Sanna/ November 9, 2016/ Conference, Development, Internet, Report, Security

In Korea in particular, hackers have distributed sophisticated and complex financial fraud android malware through various means of distribution, such as SMS phishing, Google play, compromised web servers and home routers (IoT). In some cases, both smartphone and PC users are targeted simultaneously. Inseung Yang and his team collect mobile android malware via an automated analysis system, detect obfuscations and malicious packer apps. In his presentation Inseung Yang will describe trends of malicious android apps and obfuscated mobile malware in Korea. He’ll explain the policy methods for Korean mobile banking and the attack methods used by hackers, f.ex. the stealing of certifications, fake banking apps that require the  security numbers issued to users when they open their accounts, Automatic Response Service(ARS) phishing attacks in conjunction with Call Forwarding, and the requesting of the One Time Password(OTP) number. But

DeepSec 2016 Talk: Systematic Fuzzing and Testing of TLS Libraries – Juraj Somorovsky

Sanna/ November 8, 2016/ Conference, Development, Security

In his talk Juraj Somorovsky presents TLS-Attacker, a novel framework for evaluating the security of TLS libraries. Using a simple interface, TLS-Attacker allows security engineers to create custom TLS message flows and arbitrarily modify TLS message contents in order to test the behavior of their TLS libraries. Based on TLS-Attacker, he and his team first developed a two-stage TLS fuzzing approach. This approach automatically searches for cryptographic failures and boundary violation vulnerabilities. It allowed him to find unusual padding oracle vulnerabilities and overflows/overreads in widely used TLS libraries, including OpenSSL, Botan, and MatrixSSL. Juraj’s findings encouraged the use of comprehensive test suites for the evaluation of TLS libraries, including positive as well as negative tests. He and his team used TLS-Attacker to create such a test suite framework, which finds further problems in TLS libraries. TLS-Attacker is an open source tool, and is currently being deployed for internal

DeepSec2016 Talk: Smart Sheriff, Dumb Idea: The Wild West of Government Assisted Parenting – Abraham Aranguren & Fabian Fäßler

Sanna/ November 4, 2016/ Conference, Legal, Security, Stories

Would you want to let your kids discover the darker corners of the Internet without protection? Wouldn’t it be handy to know what they do online, to be alerted when they search for dangerous keywords and to be able to control what websites they can visit and even when they play games? Worry no longer, the South Korean government got you covered. Simply install the “Smart Sheriff” app on your and your kids’ phones. Smart Sheriff is the first parental-control mobile app that has been made a legally required, obligatory install in an entire country! Yay, monitoring! Well, something shady yet mandatory like this cannot come about without an external pentest. And even better, one that wasn’t solicited by the maintainer but initiated by the OTF and CitizenLab and executed by the Cure53 team!

DeepSec2016 Talk: Of Mice and Keyboards: On the Security of Modern Wireless Desktop Sets – Gerhard Klostermeier

Sanna/ November 3, 2016/ Conference, Internet, Security

Wireless desktop sets have become more popular and more widespread in the last couple of years. From an attacker’s perspective, these radio-based devices represent an attractive target both allowing to take control of a computer system and to gain knowledge of sensitive data like passwords. Wireless transmissions offer attackers a big advantage: you don’t have to be around to attack something or someone. Plus the victims often don’t know what it happening. At DeepSec 2016 Gerhard Klostermeier will present the results of research on the matter of wireless mouse/keyboard attacks. Furthermore you he will demonstrate ways in which modern wireless desktop sets of several manufacturers can be attacked by practically exploiting different security vulnerabilities. We recommend this talk to anyone still using old-fashioned input devices for creating content. Gerhard is interested in all things

DeepSec 2016 Talk: Assessing the Hacking Capabilities of Institutional and Non-institutional Players – Stefan Schumacher

Sanna/ November 3, 2016/ Conference, Security, Security Intelligence

Cyberwar, Cyberterror and Cybercrime have been buzzwords for several years now. Given the correct context, using cyber has merits. However Cyber-Headlines are full with Cyber-Reports about Cyber-Incidents, Cyber-Hacking and Cyber-Cyber in general. However, that whole discussion does not only suffer from sensationalism of journalists and bloggers, there are also some fundamental problems, says Stefan Schumacher. We are still lacking useful definitions for modern IT security threats and we still have to think about the assessment of capabilities in the IT field.Besides institutional actors like states and their military and intelligence community we also have to assess the capabilities of non-institutional actors like terrorist groups or organised crime. Unlike the assessment of classic military strength (eg. fighting power or Kriegsstärkenachweise), assessing the capabilities and powers of actors in the IT field is much more complicated

DeepSec 2016 Talk: Why Companies Must Control Their Data in the Era of IoT – and How To – Kurt Kammerer

Sanna/ November 3, 2016/ Conference, Internet, Interview, Security

In his talk Kurt Kammerer addresses any company’s dilemma: The need for data sharing in the era of IoT while at the same time controlling access and ownership. In order to succeed in business, it is imperative to make data available to customers, suppliers and business partners. However, the explosion and the proclaimed free flow of data can turn against an organisation and threaten its very existence, if not professionally controlled. We asked Mr. Kammerer a few questions beforehand. Please tell us the top 5 facts about your talk. The relevance of “data” increases by the day and “data” is imperative to compete. Therefore, it is an asset companies must control. Data ownership is increasingly being challenged in the era of cloud/IoT (who created the data and who actually owns it?) Not exercising enough control

DeepSec 2016 Talk: Insider Threat: Profiling, Intent and Motivations of White Collar Offenders – Ulrike Hugl

Sanna/ October 31, 2016/ Conference, Security

Malicious insider threat is not only a security- or technical-oriented issue, mainly it’s a behavioural one, says Prof. Ulrike Hugl. Insiders are so-called ‘trusted’ or privileged employees, very often with legitimate access to the organization’s systems, and they are hard to catch. Furthermore, it is difficult to find appropriate predictive factors and prevention and detection measures. In fact, based on new technical developments and opportunities, data theft has become much easier these days: Mobile trends like BYOD, the increased ability to work from home, access to the organization’s systems when on the road, cloud services with related security vulnerabilities for example, as well as more and more malware opportunities have increased the potential of related attacks. Other main security obstacles and trigger factors inside and outside an organization may be, to name a few, a

Sanna/ October 21, 2016/ Conference, Interview

Please tell us the top facts about your talk. It discloses a vulnerability that affects Linux systems encrypted with Luks, and how it can be abused to escalate privileges: CVE-2016-4484 Includes a sketch of the boot sequence with a deeper insight into the initrd Linux process A brief discussion about why complexity is the enemy of security: The whole system needs to be observed. A practical real working demo attack will be presented. How did you come up with it? Was there something like an initial spark that set your mind on creating this talk? Well, this is a difficult question. Basically, it is an attitude in front of the computer. When we start a research line, we don’t stop digging until the ultimate doubt and question is addressed. After the GRUB 28 bug, we keep reviewing the rest of

DeepSec 2016 Talk: I Thought I Saw a |-|4><0.- Thomas Fischer

Sanna/ October 21, 2016/ Conference, Development, Security

Threat Hunting refers to proactively and iteratively searching through networks or datasets to detect and respond to advanced threats that evade traditional rule- or signature-based security solutions. “But what does this really mean?”, asks Thomas Fischer. “And what real impact does it have on the security team? Can we use threat hunting to provide a process to better detect and understand when you’ve been breached?” More and more security data is being produced and usually aggregated into a central location or body to hopefully take quick and informed decisions on attacks or compromises amongst a mountain of data. When you start to include data gathered from your endpoints the amount of data starts to explode exponentially. This level of data provides us with a large amount of visibility. But is having visibility enough? What

DeepSec2016 Talk: AMSI: How Windows 10 Plans To Stop Script Based Attacks and How Good It Does That – Nikhil Mittal

Sanna/ October 20, 2016/ Conference, Development, Security

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

DeepSec 2016 Talk: Where Should I Host My Malware? – Attila Marosi

Sanna/ October 18, 2016/ Conference, Internet, Security

The growth of IoT devices continues to raise questions about their role and impact on cybersecurity. Badly or poorly configured devices are easy targets for malicious actors. At first glance launching an attack against IoT devices seems challenging due to the diversity of their ecosystem, but actually an attack is very easy to execute. In his talk Attila Marosi will explain why the IoT is a cybercriminal’s paradise: “In our SophosLabs research, we focused on a very generic attack scenario that would affect almost any device using FTP services – Your router or network-attached storage (NAS) for example. These attacks typically exploit the level of trust people place on any content hosted on internal network shares. A successful attacker would abuse or compromise a default FTP guest account, place a “Trojan horse” in a visible file share and rely on human curiosity
