The only responsible Encryption is End-to-End Encryption

René Pfeiffer/ October 30, 2017/ High Entropy, Security

Last week the Privacy Week 2017 took place. Seven days full of workshops and presentations about privacy. This also included some security content as well. We provided some background information about the Internet of Things, data everyone of us leaks, and the assessment of backdoors in cryptography and operating systems. It’s amazing to see for how long the Crypto Wars have been raging. The call for backdoors and structural weaknesses in encryption was never silenced. Occasionally the emperor gets new clothes, but this doesn’t change the fact that some groups wish to destroy crypto for all of us. The next battle is fought under the disguise of responsible encryption. Deputy Attorney General Rod J. Rosenstein invented this phrase to come up with a new marketing strategy for backdoors. Once you have backdoors in any

DeepSec 2017 Talk: BitCracker – BitLocker Meets GPUs – Elena Agostini

Sanna/ October 25, 2017/ Conference

Encryption and ways to break it go hand in hand. When it comes to the digital world, the method of rapidly using different keys may lead to success, provided you have sufficient computing power. The graphics processing units (GPUs) have come a long way from just preparing the bits to be sent to the display device. Nowadays GPUs are used for a lot of computational expensive tasks. At DeepSec 2017 you will hear about keys, encryption, and storage encryption – all with the use of GPUs, but forthe purpose of cracking keys. BitLocker (formerly BitLocker Drive Encryption) is a full-disk encryption feature available in recent Windows OS (Vista, 7, 8.1 and 10). It is designed to protect data by providing encryption for several types of memory units like internal hard disks or external removable

DeepSec 2017 Talk: Who Hid My Desktop – Deep Dive Into hVNC – Or Safran & Pavel Asinovsky

Sanna/ October 17, 2017/ Conference

Seeing is believing. If you sit in front of your desktop and everything looks as it should look, then you are not in the Matrix, right? Right? Well, maybe. Manipulating the surface to make something to look similar is a technique also used by phishing, spammers, and social engineers. But what if the attacker sitting on your computer does not need to see what you see? Enter hidden virtual network computing where malicious software controls your system, and you don’t know about it. Since the past decade, financial institutions are increasingly faced with the problem of malware stealing hefty amounts of money by performing fraudulent fund transfers from their customers’ online banking accounts. Many vendors attempt to solve this issue by developing sophisticated products for classifying or risk scoring each transaction. Often, identifying legitimate

DeepSec Talk 2017: Normal Permissions In Android: An Audiovisual Deception – Constantinos Patsakis

Sanna/ October 17, 2017/ Conference, Security

The Marshmallow version was a significant revision for Android. Among the new features that were introduced one of the most significant is, without any doubt, the runtime permission. The permission model was totally redesigned, categorising the permissions into four main categories. The main concept of this categorisation is how much risk a user is exposed to when permissions are granted. Therefore, normal permissions imply the least risk for the user. However, in this case, there are some important issues. Firstly, these permissions are not actually displayed to the user; they are not displayed upon installation and the user needs to dig into several menus to find them for each app. Most importantly though, these permissions cannot be revoked. Unlike permissions categorized as dangerous, where the user can grant or revoke a permission whenever deemed

DeepSec2017 Workshop: Mobile App Attack – Sneha Rajguru

Sanna/ October 16, 2017/ Conference, Training

The world’s gone mobile. Mobile devices have surpassed the standard computer (i.e. desktop) installation multiple times. In turn this means that you will encounter these devices most definitely when testing or implementing security measures. Usually adversaries do not use the platform itself. They use software to gain entry. This is why mobiles apps are the most preferred way of delivering the attacks today. Understanding the finer details of mobile app attacks is soon becoming an essential skill for penetration testers as well as for the app developers & testers. This is why we have a special training for you at DeepSec 2017. So, if you are an Android or an iOS user, a developer, a security analyst, a mobile pen-tester, or just a mobile security enthusiast the training ‘Mobile App Attack’ is of definite

Science First! – University of Applied Sciences Upper Austria (FHOOe) supports DeepSec

René Pfeiffer/ October 12, 2017/ Conference, Security

The motto of DeepSec 2017 is „Science first!“. This is expressed by the co-located ROOTS workshop, many speakers from academics, topics fresh from the front lines of research, and a mindset that favours facts over fake content or showmanship. This is why we want to thank the University of Applied Sciences Upper Austria for their continued support of DeepSec! Their motto is Teaching and learning with pleasure – researching with curiosity, which fits nicely into the mindset of most information security researchers. They have a wide range of very interesting research projects. If you are interested in courses or collaboration as a company, let them now. We are happy to support you with your enquiry. Lest you forget: DeepSec offers a steep discount for anyone in academic research – be it student or professor.

DeepSec 2017 Workshop: Hunting The Adversary – Developing And Using Threat Intelligence – John Bambenek

René Pfeiffer/ October 12, 2017/ Conference, Security Intelligence, Training

The arsenal of components you can use for securing your organisation’s digital assets is vast. The market offers a sheer endless supply of application level gateways (formerly know as „firewalls“), network intrusion detection/prevention systems, anti-virus filters for any kind of platform (almost down to the refrigerator in the office), security tokens, biometrics, strong cryptography (just stay away from the fancy stuff), and all kinds of Big Data applications that can turn shoddy metrics into beautiful forecasts of Things to Come™ (possibly with a Magic Quadrant on top, think cherry). What could possibly go wrong? Well, it seems attackers still compromise systems, copy protected data, and get away with it. Why is that? Easy: You lack threat intelligence. Security often doesn’t „add up“, i.e. you cannot improve your „security performance“ by buying fancy appliances/applications and

DeepSec2017 Workshop: SAP CTF Pentest : From Outside To Company Salaries Tampering – Yvan Genuer

Sanna/ October 10, 2017/ Conference, Training

The SAP business suite is widespread among enterprises. It is the heart of the operation, at least in terms of business logic, administration, accounting, and many other cornerstones of big companies. SAP itself was founded in 1972. Its software has now grown up and lives with the Internet and cloud platforms next door. Due to the SAP software being a platform itself, it is quite unwieldy for hackers to handle. If you believe this, then we recommend the SAP CTF Pentest training at DeepSec 2017! Yvan Genuer has something to show to you: SAP is boring, too big or too complicated? What about learning SAP Security during a fun CTF workshop? Additionally we’ll provide you with a pre-configured attacker VM with all tools required to perform workshop activities. Attendees learn how to work against

DeepSec 2017 Talk: How To Hide Your Browser 0-days: Free Offense And Defense Tips Included – Zoltan Balazs

Sanna/ October 9, 2017/ Conference

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: BITSInject – Control Your BITS, Get SYSTEM – Dor Azouri

Sanna/ October 8, 2017/ Conference, Internet, Security

Microsoft has introduced the Background Intelligent Transfer Service (BITS) into Windows 2000 and later versions of the operating system. Windows 7 and Windows Server 2008 R2 feature the version 4.0 of the protocol. BITS is designed to use idle bandwidth in order to transfer data to and from servers. BITS is an obedient servant, and it may be abused into doing transfers on behalf of others. Dor Azouri will present his findings regarding BITS at DeepSec 2007. Windows’ BITS service is a middleman for your download jobs. You start a BITS job, and from that point on, BITS is responsible for the download. But what if we tell you that BITS is a careless middleman? Current Windows software comes packaged with a mix of old and new features and components. New, shiny features and

DeepSec 2017 Talk: XFLTReaT: A New Dimension In Tunnelling – Balazs Bucsay

Sanna/ October 7, 2017/ Conference, Security

“Our new tool XFLTReaT is an open-source tunnelling framework that handles all the boring stuff and gives users the capability to take care of only the things that matter”, says Balazs. “It provides significant improvements over existing tools. From now on there is no need to write a new tunnel for each and every protocol or to deal with interfaces and routing. Any protocol can be converted to a module, which works in a plug-and-play fashion; authentication and encryption can be configured and customised on all traffic, and it is also worth mentioning that the framework was designed to be easy to configure, use and develop.” We asked Balazs Bucsay a couple more questions about his talk: Please tell us the top 5 facts about your talk. Tunnelling is not new at all, but

DeepSec 2017 Talk: Insecurity In Information Technology – Tanya Janca

Sanna/ October 6, 2017/ Communication, Conference, Security

A lot is expected of software developers these days; they are expected to be experts in everything despite very little training. Throw in the IT security team (often with little-to-no knowledge of how to build software) telling developers what to do and how to do it, and the situation is further strained. This silo-filled, tension-laced situation, coupled with short deadlines and mounting pressure from management, often leads to stress, anxiety and less-than-ideal reactions from developers and security people alike. In this talk Tanya Janca will explain how people’s personal insecurities can be brought out by leadership decisions in the way we manage our application security programs, and how this can lead to real-life vulnerabilities in software and other IT products. This is not a soft talk about “feelings”, this is a talk about creating

DeepSec 2017 Talk: Bypassing Web Application Firewalls – Khalil Bijjou

Sanna/ October 5, 2017/ Conference, Security

Everyone has firewalls or filters. They are now called application-level gateway (ALG) and have lots of features included. Algorithms, signatures, heuristics, protocol checks, verification; you name it. It’s all in there. But does it work? Obfuscation and evading technology has been around since the first filter was created. Anticipating what data might look like is hard, and some protocols were designed to be as ambivalent as possible, one might think. At DeepSec 2017 Khalil Bijjou will show you what can be done being evasive in the web. Security experts perform security assessments of web applications in order to identify vulnerabilities that could be exploited by malicious users. Web Application Firewalls add a second layer of protection to web applications in order to mitigate these vulnerabilities. The attempt to bypass Web Application Firewalls is an
