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

DSGVO / GDPR / RGPD Update – We have Policies and Stuff!

René Pfeiffer/ May 25, 2018/ Administrivia, High Entropy

In information security policies are like opinions – everyone has one or more. So this is why we did some updating. You can now find our privacy policy on the main DeepSec web site and on our blog. We use few third party services, because most of our infrastructure is hosted on our own systems. When it comes to (tele)communication, payment services, and (sadly) email we have to rely on operators doing this for us. Our email infrastructure will move in the near future (i.e. in 2018). We will announce the change via your local DNS resolver when the time comes. 😊 Bear in mind that we take the agile approach when it comes to developing policies. Publish often, do rolling releases. At least that is how we understand the process. A policy is

#efail, Crypto, HTML, PDF, and other complex Topics

René Pfeiffer/ May 14, 2018/ High Entropy, Security

You probably have noticed the #efail hashtag that came with the claim that the crypto world of PGP/GPG and S/MIME is about to end. Apocalyptic announcements were made. The real news is due for 15 May 2018 (i.e. the publication with all the facts). There was even the advice to stop using encryption until more information is known. The authors of the bug claimed that responsible disclosure was being followed. Well, it seems that this is not the case. Judging from the Internet response, the bug depends on the content of the encrypted message, not on the protocol of the encryption or the encryption tools. Lessons learned so far: It is a bug in some mail user client software. It’s all about the content of the message and how it gets interpreted. Responsible disclosure

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

The Grotesqueness of the “Federal Hack” of the German Government Network

Sanna/ March 19, 2018/ High Entropy, Security Intelligence

[Editor’s note: This article was originally published on the web site of the FM4 radio channel of the Austrian Broadcasting Corporation. We have translated the text in order to make the content accessible for our English-speaking audience. We will follow-up on it with an article of our own about attribution, digital warfare, security intelligence, and the DeepINTEL conference.] A friendly secret service knew more about espionage against the German government network than the German counterintelligence. Three months after the hack was discovered, the attackers are still somewhere in this huge federal network. By Erich Moechel for fm4.orf.at One week after the announcement of the attack on the security network of the German Federal Government details only leak slowly.

DeepSec 2017 Talk: How I Rob Banks – Freakyclown

Sanna/ November 14, 2017/ Conference, High Entropy, Security

You are in for an adventure at DeepSec this year. We have a tour on robbing banks for you: A light-hearted trip through security failures both physical and electronic that have enabled me over the years to circumvent security of most of the worlds largest banks. Through the use of tales from the front line and useful illustrative slides, I will attempted to take you through the lessons to be learned from an ethical hacker with a penchant for breaking into the impossible. Let me take you on a rollercoaster ride of epic fails and grandiose plans and my Jason Bourne like adventures including Lockpicking, Kidnap, Police chases and multi-million pound bank heists. FC is a well-known ethical hacker and social engineer. He has been working in the infosec field for over 20 years

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!

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 Schedule Update, Review Status, Disputes, and Trainings

René Pfeiffer/ September 26, 2017/ Administrivia, Conference, High Entropy

The DeepSec 2017 schedule is still preliminary. We are almost done, and we have a small update. Some of you have noticed that the schedule featured a training about mobile security. The outline as shown as in the schedule was identical to a different course from a different trainer. We received a complaint, we got the course materials to compare, and it turned out that only the outline of the workshop as shown online was identical, and the original table of contents was not part of the submission we received during the call for papers. The dispute has been settled. The trainer has apologised to the creator of the original table of contents. Nevertheless the trainer has asked to withdraw his submission. This means we will try to replace the slot in the schedule

44CON revisited: Secure Design in Software is still a new Concept

René Pfeiffer/ September 20, 2017/ High Entropy, Interview, Security

We have been to 44CON, and we returned with lots of ideas and scary news about the state of security in devices and applications. Given the ever spreading Internet of Things (IoT) you can see why connecting random devices via a network with no second thoughts about design, updates, or quality control is a bad idea. Don Bailey illustrated this perfectly in the keynote titled The Internet of Us. His presentation touched all of information security, but IoT featured a prominent role. We are really surrounded by the Internet of SIM cards (sadly which we cannot call IoS). This opens up a new perspective and demystifies the IoT hype. You should watch Matt Wixey’s talk Hacking invisibly and silently with light and sound as soon as the videos are published. Matt discussed hardware hacking

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

Mythbusting: Anti-Virus Research considered dangerous

Sanna/ August 18, 2017/ High Entropy, Internet, Security Intelligence, Stories

Everyone doing research in information security or doing any work in this field takes some risks. Since most of the „cyber stuff“ is black magic to others not working in this context, there are a lot of problems and severe misunderstandings. The Crypto Wars still haven’t been decided in favour of mathematics. Real people prefer end-to-end encryption over insecure communication all of the time. Proposals of severely damaging information security for all of us by using sanctioned malicious software are still being debated in parliaments. Backdoors, covert or otherwise, are no line of any defence, as many military strategists will readily tell you. Marcus Hutchins was in the news recently, because of claims that he developed a strand of malware tied to attacks on financial institutions. While you can debate all you want about
