Dringende Warnung vor Hintertüren in Citrix-Systemen by Erich Moechel for fm4.ORF.at An unknown number of these VPN gateways, which protect important networks in Austria such as electronic official traffic, ministries, supermarket chains, etc., are infected with malware. Ransomware blackmailers are now attacking one network after another. After the huge security gap in Citrix dial-up systems (“Shitrix”) at the beginning of the year, the consequences are now coming to light. The German security consultants HiSolutions have recently discovered a number of encryption attacks that were carried out through back doors installed at the time. Large company and authority networks are affected, which, like the electronic file traffic of the Republic (ELAK), were open for weeks over the turn of the year. Almost all of these “VPN gateways” were backed up by software updates much too
EU-Ministerrat diskutiert wieder Hintertüren in Verschlüsselung by Erich Moechel for fm4.ORF.at Gilles de Kerchove, EU’s anti-terror coordinator, is once again working against secure encryption per se. Since these new demands by law enforcement officials on the EU Council of Ministers are nowhere openly accessible, this confidential Council document is published in full by FM4. The corona virus pandemic has led to a surge in teleworking worldwide. Instead of behind firewalls in secure corporate networks, millions of employees worldwide work from insecure home offices. The only real protection is the end-to-end encryption (E2E) of the data traffic. In the middle of this scenario, the “Five Eyes” secret service alliance is starting the next phase of its global campaign against secure encryption. Again, police law enforcement is used as a vehicle. After the United States, the European protagonist
US-Gesetzesentwurf gegen sichere Verschlüsselung von Chats by Erich Moechel for fm4.ORF.at A new US law on “Access by law enforcement officers to encrypted data” is intended to force chat providers such as Signal or WhatsApp to incorporate back doors into their security architectures. In the United States, a bill is on its way to the Senate that has stunned the IT industry. The planned law on “Access by law enforcement officers to encrypted data” turns upside down all the rules that have been in force on the WWW for 25 years. Encrypted chats and data backup for a wide audience should therefore only be offered if the provider has duplicate keys. That would be the end of end-to-end encryption (E2E) from Signal, WhatsApp and others. The same applies to hardware manufacturers who have to provide access
Schon zehn EU-Staaten setzen auf dezentrale Coronavirus-Apps by Erich Moechel for fm4.orf.at Apple and Google also support the privacy-friendly, decentralized protocol DP-3T. Without technical support in the operating systems of these two groups, no app with Bluetooth tracing can deliver useful results. The decision by Austria and Switzerland to use a corona virus app with decentralized data storage (DP-3T) triggered a chain reaction. By Friday, ten EU countries had already left the large-scale “Pan-European Project for Data Protection-Compliant Person Tracing” (PEPP-PT). The centralized data collection of PEPP-PT leaves all possibilities for data mining open, a deanonymisation of the data is also included. Apple and Google, which support the DP-3T standard, are constantly publishing new specifications for the necessary app interfaces in Android and IOS. Without the support of these two companies, whose operating systems

Cyberhusarenstück schlug Angreifer im Außenministerium for fm4 by Erich Moechel [We translated this article, because DeepSec actively supports young talents and students. We are looking for organisation and companies that would like to help us in our support. Furthermore, we like to make Erich’s well-researched and well-written articles available for a wider audience.] It was young Technicians who fended off the dreaded cyber Troop Turla. After a short Time they cracked the tricky Encryption of the Turla Trojan. The National Security Council, which the NEOS party convened to discuss the cyberattack on the Federal Ministry for European and International Affairs, meets on Friday. NEOS criticize the cumbersome structures in cyber defence and, above all, that it is not ready to work properly. The quick defence of the notorious cyber troop (APT) Turla is rather
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
Everything that’s old is new again, and if you work in security long enough, you’ll see the same ideas re-invented and marketed as the new new thing. Or, you see solutions in search of a problem, dusted off and re-marketed in a new niche. At this year’s DeepSec conference the keynote will be given by Marcus Ranum, who set up the first email server for whitehouse.gov. He will reflect upon over 30 years of IT security and make a few wild guesses for where this all may wind up. Spoiler alert: Security will not be a “solved” problem. Marcus answered a few questions beforehand: Please tell us the Top 5 facts about your talk. I’ll be talking about how the security market evolves from here. I’ll be talking about the relationship between security and management It’s going to be depressing. I have
DeepSec2016 Talk: Smart Sheriff, Dumb Idea: The Wild West of Government Assisted Parenting – Abraham Aranguren & Fabian Fäßler
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!
Sitting through the Rookie Track at BSidesLondon is something we really enjoy. This year the quality of the presentations was amazing. Of course, the rookie’s mentors take a part of the blame for that. Good training gives you always a head start. Nevertheless someone has to stand in front of the crowd and fill the 15 minutes slot with content. All rookies did a good job. It was hard to pick a clear winner. The jury took more than three iterations to find a conclusion. Locard made it, and we welcome him to DeepSec 2016 in November. Honourable mentions go to @Shlibness, @Oxana_Sereda and @callygarr. For you we have some thoughts on the presentations we saw and on the methods being used. Think of your presentation as code. Make it lean and mean. It’s
Like the Force wireless data/infrastructure packets are all around us. Both have a light and a dark side. It all depends on your intentions. Lacking the midi-chlorians we have to rely on other sources to get a picture of the wireless forces in and around the (network) perimeter. At DeepSec 2015 Milan Gabor held a presentation about visualisation of wi-fi packets: Today visualizing Wi-Fi traffic is more or less limited to console windows and analyze different logs from an aircrack-ng toolset. There are some commercial tools, but if we want to stay in the Open/Free Source Code (FOSS) area we need to find better solutions. So we used ELK stack to gather, hold, index and visualize data and a modified version of an airodump tool for input. With this you can create amazing dashboards,
Unfortunately the Internet doesn’t follow the rules of economic theory. Unlimited growth is a myth best kept for feeding your unicorns. Of course, the Internet has grown, but the mathematics and physics behind network flows stay the same. If your pipe is full, then you are going nowhere. This is why Distributed Denial of Service (DDoS) attacks still work. You can counter or evade these attacks, but they can happen. We invited Dave Lewis of Akamai to DeepSec 2015 to hear his view on the current state of affairs where DDoS is concerned. For the record: DDoS is not hacking and no hacking attack. Spread your „cyber“ somewhere else.
The data protocols of SmartHomes are the FBI’s wet dream. Why? Because they have no security design. Take ZigBee for example. ZigBee is one of the most widespread communication standards used in the Internet of Things and especially in the area of smart homes. If you have for example a smart light bulb at home, the chance is very high that you are actually using ZigBee by yourself. Popular lighting applications such as Philips Hue or Osram Lightify and also popular smart home systems such as SmartThings or Googles OnHub are based on ZigBee. ZigBee provides also security services for key establishment, key transport, frame protection and device management that are based on established cryptographic algorithms. So a ZigBee home automation network with applied security is secure and the smart home communication is protected?
Even if you are not running a mainframe you probably have some old applications which you still need and whose code you cannot lift into the present (technology-wise). This is something you need to address. Despite decades of security research and authentication standards there’s still a vast amount of systems with custom solutions and embedded user databases. Such systems are typically hard to securely integrate with others. We analysed an existing system of an organisation with approximately 12.000 sensitive user data sets and uncovered severe vulnerabilities in their approach. We developed a minimal, secure Single-Sign-On-Solution and demonstrated the feasibility of implementing both a minimal Identity Provider and a minimal Service Provider with only a few lines of code. We provided a simple blueprint for an Identity Provider and an easy to use Service Provider
At DeepSec 2011 Constantinos Patsakis and Kleanthis Dellios held a presentation titled “Patching Vehicle Insecurities”. They pointed out that the car is starting to resemble more to a computer with mechanical peripherals (incase you haven’t seen their talk, please do!). This is true for all types, not only the modern cars powered by electricity alone. But there is more. Modern cars are connected to networks (i.e. the Internet or the mobile phone network). This means that your method of transportation is part of the dreaded Internet of Things. Given the design flaws we have seen in talks given at DeepSec, there is no surprise that this is a breeding ground for major trouble. The Allgemeiner Deutscher Automobil-Club (ADAC), a German motoring association, discovered a lapse in the communication between BMW cars and the servers
The first recording of DeepSec 2014 has finished post-processing. Just in time for the holidays we have the keynote presentation by Alex Hutton ready for you. Despite its title “The Measured CSO” the content is of interest for anyone dealing with information security. Alex raises questions and gives you lots of answers to think about. Don’t stay in the same place. Keep moving. Keep thinking.
