New in the DeepSec Ticket Shop: Tor Tickets for Early Birds and InfoSec Minds

René Pfeiffer/ July 17, 2018/ Administrivia, Discussion, High Entropy, Security

We have a new category in the DeepSec ticket shop. We now have Tor tickets! Why is that? Well, information security relies heavily on the tools of the trade and the knowledge to use them. Tools can be created and used, knowledge can be shared and used. This is not a new insight. The special Tor tickets are a way to help the German non-profit registered association Zwiebelfreunde e.V. for rebooting their infrastructure. They run Tor nodes and provide the necessary infrastructure to do this. Members of Zwiebelfreunde have been speakers at DeepSec in the past because they are also active security researchers. The difference between the Tor ticket and the normal ticket price will be given to them to recover the damage to their infrastructure. Security tools such as Tor are widely used

Thoughts on the Information Security Skill Set

René Pfeiffer/ July 13, 2018/ Discussion, Security

As mentioned in an earlier blog article we moved our office infrastructure to a new location. Once you use a space for more than a decade things inevitably pile up. So I had to sort through hardware, software (on optical storage hardware and floppy disks), lecture notes from a previous life, ancient project documentation, and notes on ideas for a brighter future. Most things were thrown away (i.e. responsibly recycled), some stuff could be saved by enthusiasts (for example the two old Amigas that were sitting in the basement). All of the things we had to move had a purpose once. The main purpose was to get familiar with technology, accumulate knowledge, and understand how things work. This is essentially the hacker mindset, also found among scientists. Given the many presentations at past DeepSec

BSidesLondon 2018 Rookie Track Follow-Up

René Pfeiffer/ June 8, 2018/ Conference, Discussion, High Entropy

We would like to share some impressions about the BSidesLondon 2018 Rookie Track presentations. It gets hard and harder to tell which one of the talks is the best. And picking a winner is not the right approach. We do this, because we can only invite one person to DeepSec, and because the intention is to have a motivation to work hard on the presentation. From what we have seen, we were quite impressed. The quality has much improved, also thanks to the tireless efforts of the mentors (if you see someone with a mentor badge, please buy them a drink!). Apart from the 15 minute time slot some talks were hard to distinguish from their bigger cousins in the main tracks. The topics were well-chosen. The mix was great. Every single rookie did

Big Data Analytica – What Attackers might be after

René Pfeiffer/ June 8, 2018/ Discussion, High Entropy, Security Intelligence

A while ago the Cambridge Analytica issue rocked the news and the online discussions about how personal data and profiles should be used. Frankly the surprise of data being abused comes as a surprise. The terms and conditions of most online portals, services, and platforms contains lots of rights – which you give to the owner of the platform. Once something is concentrated, cached, and accessible to digital evaluation, it will be harvested for its content and context. It’s as simple as that. This has always been the case. Penetration testers (best case) select their targets based on this criterion (among others). What has all of this to do with information security? Well, information security, just as the social media platforms, just can’t do without analysing data. The difference is how to protect and

Manufacturers integrate Blockchain into Processors to counter Spectre and Meltdown

René Pfeiffer/ April 1, 2018/ Discussion, High Entropy

The Spectre and Meltdown security vulnerabilities gathered a lot of attention in January. Processor manufacturers have rushed to fix the design of the chips and to patch products already in production. The vulnerabilities show that secure design is critical to our modern infrastructure. Computing has become ubiquitous, so has networking. The current fixes change the microcode on the chips. Altering the flow of assembler instructions is bound to have a detrimental impact on performance. There is not much you can do about this – but there is hope. Future generations of processors will have a defence against unknown security vulnerabilities – the blockchain! The past decade in information security has taught us that a pro-active holistic approach to IT defence is not enough. To counter unknown threats you have to go below 0(day). The

Metrics, Measurement, and Information Security

René Pfeiffer/ March 28, 2018/ Discussion, High Entropy, Security

Metric is a great word. Depending how you use it, it changes its meaning. The metric of a network path is quite different from the metric system. When it comes to measuring something, the might be an agreement. Why bother? Because we have heard of the term security metrics being used for something which should better be called security statistics. In mathematics a metric is a function which tells you the distance between each pair of elements in a set. While this does not necessarily have to do something with distance, it is a fitting analogy. It also connects metric to physics. Measuring how far two points are apart gives you usually a distance (either a straight line or a sum of straight lines). In essence measuring something boils down to comparing your object

Advanced and In-Depth Persistent Defence

René Pfeiffer/ March 26, 2018/ Discussion, Security Intelligence

The attribution problem in digital attacks is one of these problems that get solved over and over again. Of course, there are forensics methods, analysis of code samples, false flags, mistakes, and plenty of information to get things wrong. This is nothing new. Covering tracks is being done for thousands of years. Why should the digital world be any different? Attribution policy tactics, APT, is part of the arsenal and thus part of the threats you are facing. It has less impact though, because it is only of interest when your defence is breached – and this means you have something else to worry about. Attribution is not useful for defending against threats. While you can use to to „hack back“, this will most probably not help you at all. The main problem with

DeepSec 2018 calls for Trainings and Content – Focus Mobility

René Pfeiffer/ January 31, 2018/ Call for Papers, Conference, Discussion

The DeepSec 2018 Call for Papers is open. The focus for this year is mobility. Mobile networks and mobile devices have established themselves firmly in our society. And mobility doesn’t end here. Transport is transforming into new technologies by incorporating access to data networks (yes, that’s the „Cloud“), the power grid (think electric vehicles), drones, new propulsion systems, artificial intelligent (sometimes even both!) personal assistants and algorithms (mathematics has become mainstream). The ever growing number of dependencies between components are a fertile breeding ground for cascading errors that impact more than your new car or your latest order from your favourite online shop. Information security must become as mobile as home deliveries of goods and electric power. And it must become common. Infosec isn’t optional any more. Since bug logos have captured the minds

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

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!

DeepSec 2017 Talk: Hacking The Brain For Fun And Profit – Stefan Hager

Sanna/ October 2, 2017/ Conference, Discussion

You are what you think. At least we think so. Is this mental model the right way to explore our surroundings and our interconnected world? Well, let’s find out by thinking about it. When we’re talking and thinking about security, we very often have a rather fixed mindset and keep using what we think are proven methods. We tend not to question our decisions and thoughts, and the way how our brains work reaffirms our bias and our mediocre choices. In this talk we take a closer look at how we are thinking, and how we can change or expand this as well as our perception, by hacking into our own brains in order to get a clearer picture of what we really want and need. New ways of thinking and creativity can be

DeepINTEL Conference approaches the next generation of IT Security

Sanna/ August 31, 2017/ Conference, Discussion, Security Intelligence

Strategic Information Security: Predicting the Present DeepINTEL Conference presents Approaches to the Next Generation of Security Many products and approaches of information security are trying hard to predict the future. There is always a lot of talk about threats of the future, detection of attacks before they arise or the magic word “pro-active”.  But the prediction of the future does not benefit your business if the present is still unknown. When it comes to information security this means: Do you now know enough about your current situation to make the right decisions within the next few hours? The DeepINTEL seminar conference, which takes place on 21st/22nd of September in Vienna, focuses on this strategic question. Analogies distort Perception and Facts Analogies are often used to illustrate connections. Especially in the areas of IT security,

Decline of the Scientific Method: New (Austrian) “Trojan” Law without Technical Expertise

Sanna/ August 3, 2017/ Discussion, High Entropy, Security

The Crypto Wars are still raging despite everyone relying on secure communication. Everyone means everyone. The good thing is that mathematics still works, even though some people wouldn’t want it to. The latest cryptographic review comes from Amber Rudd, the current UK Home Secretary. She said recently: “Real people often prefer ease of use and a multitude of features to perfect, unbreakable security.” The corollary in turn states that DeepSec conferences aren’t attended by real people. Since we are not yet a purely robot-based event, there is something wrong with this approach to secure communication. The common denominator is simply the lack of technical expertise. There is no surprise there. Ever since the Internet was discovered by the rest of the world (which was in the 1990s, don’t get fooled by web sites who

Unicorns in the Wild – Information Security Skills and how to achieve them

René Pfeiffer/ July 27, 2017/ Discussion, High Entropy, Security

Everyone talks about information security, countering „cyber“ threats, endless feats of hackers gone wrong/wild, and more epic stories. Once you have realised that you are reading the news and not a script for a TV series, you are left with one question: What are information security skills? The next question will probably be: How do you train to be „information secure“? Let’s take a look at possible answers. First of all, yes, you can study information security or security-related topics. Universities, schools, and companies offer lectures, training, exercises, etc. Great. However it may not help you right away. We talked with top quality head hunters from a nameless big corporation. When they look for infosec specialists, they filter for anyone having worked in three different fields related to computer science (applied or otherwise) for

Malicious Software explores new Business Models – Politics

René Pfeiffer/ July 19, 2017/ Discussion, Internet, Security

Malicious software has become a major component of criminal business and geopolitics. In addition it is a convenient explanation for anything one does not want to investigate. Since code always come from somewhere you have to ask yourself many more questions when it comes to infected networks and compromised hosts. What is the agenda of the day? Journalist Erich Moechel has written an article about the arms race regarding malicious software. We have translated the original text from German to English. Expect the state of cyber in your network to rise in the course of the next years. Arms race with Malicious Software enters a dangerous Phase The enormous damage done by “Petya” and “WannaCry” can be traced back to a single, reworked tool from the leaked NSA pool of the “Shadow Brokers”.
