Meltdown & Spectre – Processors are Critical Infrastructure too

René Pfeiffer/ January 6, 2018/ Discussion, High Entropy

Information security researchers like to talk about and to analyse critical infrastructure. The power grid belongs to this kind of infrastructure, so does the Internet (or networks in general). Basically everything we use has components. Software developers rely on libraries. Usually you don’t want to solve a problem multiple times. Computer systems are built with many components. Even a System on a Chip (SoC) has components, albeit smaller and close to each other. 2018 begins with critical bugs in critical infrastructure of processors. Meltdown and Spectre haunt the majority of our computing infrastructure, be it the Cloud, local systems, servers, telephones, laptops, tablets, and many more. Information security relies on the weakest link. Once your core components have flaws, then the whole platform may be in jeopardy. In 2017 malicious hypervisors in terms of

DeepSec 2017 Presentation Slides

René Pfeiffer/ December 1, 2017/ Administrivia, Conference

While the videos are on their way to the rendering farm, the presentation slides for DeepSec 2017 can already be downloaded. We put them online as soon as we get the final version from our speakers. If you do some guessing URL-wise you can also find the presentations of past conferences at the very same spot. Since we collect the final slides after the conference and not ask speakers to put USB sticks into their computers during the conference, the download repository will fill in time. Unfortunately we cannot speed up this process. So bear with us, we are as curious as you (especially since some of us never get the see any presentation at DeepSec because there is too much to do). As for the videos, all speakers and attendees will also get

DeepSec2017 U21 Talk: Lessons Learned: How To (Not) Design Your Own Protocol – Nicolai Davidsson

Sanna/ November 15, 2017/ Conference, Development, Security

“One of the first lessons of cryptography is “don’t roll your own crypto” but we were bold enough to ignore it”, says Nicolai. “Single Sign-On is so 2016 which is why we’d like to introduce its replacement, Forever Alone Sign-On – FASO. This talk will discuss one of the ugliest SSO solutions you’ll ever see, its updated, slightly less ugly, iteration, and, ultimately, FASO. We’ll discuss the use cases, questionable decisions made during the planning process, the actual self-rolled, totally vulnerable, cryptography, and the even worse code architecture. In all seriousness: The talk reflects on the design process of a SSO protocol and its first two iterations, going from a semi-functional workaround to an experimental OAuth-and-the-like alternative utilizing pre-shared keys, symmetric cryptography and implicit authentication.”   Nicolai is a security researcher at zyantific and

ROOTS: Out-Of-Order Execution As A Cross-VM Side Channel And Other Applications – Sophia d’Antoine

Sanna/ November 15, 2017/ Conference, Security

Given the rise in popularity of cloud computing and platform-as-a-service, vulnerabilities, inherent to systems which share hardware resources, will become increasingly attractive targets to malicious software authors. In this talk, Sophia will introduce a novel side channel across virtual machines through the detection of out-of-order execution. She and her colleagues created a simple duplex channel as well as a broadcast channel. She’ll discuss possible adversaries for this channel and proposes further work to make this channel more secure, efficient and applicable in realistic scenarios. In addition, she considers seven possible malicious applications of this channel: theft of encryption keys, program identification, environmental keying, malicious triggers, denial of service attacks, determining VM co-location, malicious data injection, and side channels. We asked Sophia a few questions about her talk. Please tell us the top 5 facts

ROOTS: On The (In-)Security Of JavaScript Object Signing and Encryption – Dennis Detering

Sanna/ November 14, 2017/ Security

JavaScript Object Notation (JSON) has evolved to the de-facto standard file format in the web used for application configuration, cross- and same-origin data exchange, as well as in Single Sign-On (SSO) protocols such as OpenID Connect. To protect integrity, authenticity and confidentiality of sensitive data, JavaScript Object Signing and Encryption (JOSE) was created to apply cryptographic mechanisms directly in JSON messages. We investigated the security of JOSE and present different applicable attacks on several popular libraries. We introduce JOSEPH (JavaScript Object Signing and Encryption Pentesting Helper) – our newly developed Burp Suite extension, which automatically performs security analysis on targeted applications. JOSEPH’s automatic vulnerability detection ranges from executing simple signature exclusion or signature faking techniques, which neglect JSON message integrity, up to highly complex cryptographic Bleichenbacher attacks breaking the confidentiality of encrypted JSON messages.

DeepSec2017 Talk: Building Security Teams – Astera Schneeweisz

Sanna/ November 14, 2017/ Conference

While ‘security is not a team’, you’ll find that most companies growing just beyond 60-80 people start employing a group of people focusing primarily on the topic. But the culture of secure engineering in a company does not only strongly correlate with when you start building a security team – it becomes (and grows as) a matter of how they connect with the rest of your organization, and make security, adversarial thinking, and the care for user safety and privacy part of everyone’s concern. In this talk, Astera will review what the purposes of a security team can be, which challenges you’ll face, how you can make it scale beyond the team’s boundaries; as well as proven good practices of running (fairly operational) engineering teams themselves. Whether your organization already has a security team

Notes on the ROOTS Schedule and the Conference

René Pfeiffer/ November 14, 2017/ Administrivia, Conference, Discussion

We are all set for the conference on Thursday. We did some last minute changes to the schedule due to some speakers running into issues, but we can confirm almost all presentations.You may have noticed the ROOTS schedule. It’s a bit shorter than DeepSec’s, but both events are not competing. The review for ROOTS is a lot harder, because the presentation is about a scientific publication. This means your submission gets peer-reviewed and voted by the programme committee. We received some content more suitable for, let’s say, standard events. This won’t do, and this is why you see the best submissions of ROOTS published in the schedule. All in all we are very glad to present you high quality presentations from speakers who really know information security. Enjoy! See you at DeepSec!

Screening of “The Maze” at DeepSec 2017

René Pfeiffer/ November 3, 2017/ Administrivia, Conference, High Entropy

We have some news for you. Everyone attending DeepSec 2017 will get a cinematic finish on the last day of the conference. We will be showing The Maze by Friedrich Moser. For all who don’t know Friedrich’s works: He is the director of A Good American which was screened at DeepSec 2015. The Maze is a documentary covering terrorism, counter-terrorism, surveillance, business, and politics. So it’s basically information security in a nutshell. Right after the closing of DeepSec you can enjoy The Maze – with popcorn and hopefully everyone who is attending DeepSec. We have seen the documentary before, and we highly recommend it!

DeepSec 2017 Workshop: Smart Lockpicking – Hands-on Exploiting Contemporary Locks and Access Control Systems – Slawomir Jasek

Sanna/ October 31, 2017/ Conference, Training

You can, quite reasonably, expect smart locks and access control systems to be free from alarming security vulnerabilities – such a common issue for an average IoT device. Well, this training will prove you wrong. After performing multiple hands-on exercises with a dozen of real devices and various technologies, you will never look at the devices the same way. Smart lockpicking is something to scare you, not just on Halloween.     We asked Slawomir a few questions about his training: Please tell us the top 5 facts about your workshop. Focused on hands-on, practical exercises with real devices Lots of various topics and technologies covered Regardless if you are a beginner or a skilled pentester, you will learn something new and have a good time Many exercises designed as “homework”, possible to repeat

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
