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.

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!

Administrivia: How to access ROOTS and DeepSec 2017

René Pfeiffer/ August 22, 2017/ Administrivia, Conference

We have received some question on how to attend the presentations of the 1st Reversing and Offensive-oriented Trends Symposium (ROOTS) 2017. It’s very easy. ROOTS is co-hosted with DeepSec 2017. This means if you attend DeepSec, you also attend ROOTS. In turn attending ROOTS gives you also access to the DeepSec conference. So you only need one ticket to access both events. Bear in mind that our sponsors can give you discount codes for buying tickets. In addition we have a special programme for academics to give you the academic discount for the tickets. Don’t forget: Buying early means saving money! The early bird tariff is still valid until 25 September 2017. After that the ticket price increases. Do us and yourself a favour and book as early as possible. Thank you! See you

DeepSec 2017 Schedule, ROOTS, and Closing of Call for Papers

René Pfeiffer/ August 3, 2017/ Administrivia, Conference

Thanks a lot for your submissions! We are currently in the final phase of the review. Expect the first draft of the schedule for the end of the week. Important: Don’t forget that the Call for Papers for the 1st Reversing and Offensive-oriented Trends Symposium 2017 (ROOTS) is still open and was extended to 15 August 2017! Please submit and help us to put more science into infosec! Given the headlines in the IT (security) news we need all the facts we can get.

ROOTS 2017, DeepSec, and DeepINTEL Call for Papers are still open

René Pfeiffer/ June 26, 2017/ Call for Papers, Internet, Security, Security Intelligence

Our wonderful world of technology is full of surprises, bugs, intentional weaknesses, adversaries, defenders, vendors, and users. Some software just got more lines of code instead of a decent audit or refactoring. Everything is turning smart, but no one knows what smart really means. Big Data is all the fashion, Big Knowledge still isn’t. So there is ample opportunity for security research. And we haven’t mentioned recent weaknesses such as Stack Clash or broken hyperthreading yet. Strategy hasn’t evolved much either. Most high profile attacks seem to contain a lot of cyber, originating from Russia, USA, Israel, North Korea, or China. The context matters, as do the agendas of all parties involved. A thorough and careful analysis can shape the digital defence of your future. This is why we like to discuss methods, incidents,

Call for Papers: 1st Reversing and Offensive-Oriented Trends Symposium (ROOTs) 2017

René Pfeiffer/ May 1, 2017/ Call for Papers, Conference

ROOTs 2017 The first Reversing and Offensive-Oriented Trends Symposium (ROOTs) 2017 opens its call for papers. ROOTs is the first European symposium of its kind. ROOTS aims to provide an industry-friendly academic platform to discuss trends in exploitation, reversing, offensive techniques, and effective protections. Submissions should provide novel attack forms, describe novel reversing techniques or effective deployable defenses. Submissions can also provide a comprehensive overview of the state-of-the-art, and pinpoint promising areas that have not received appropriate attention in the past. To facilitate interaction with industry, the ROOTs ticket will be valid for all DeepSec conference tracks on both days, including the industry tracks, and the DeepSec conference tickets for the industry track will be valid for ROOTs. The usual rules for academic discounts apply. Please contact the DeepSec staff or our sponsors for

DeepINTEL Update, Science First Campaign, Early Birds, and other News

René Pfeiffer/ April 28, 2017/ Administrivia, Conference

The Easter break is over. We didn’t sleep (much), and we did not look for Easter eggs in software either. Instead we did a bit of work behind the scenes. DeepSec 2017 will have some more content due to the co-hosted ROOTs workshop. The full call for papers will be ready on 1 May 2017. We will publish the text here on this blog, and email it to interested researchers. In the meantime the DeepSec 2017 Call for Papers is waiting patiently for your submission. In case you haven’t noticed, the DeepSec and DeepINTEL ticket shops are online. Please book your ticket as early as possible! Every year so far we had some people at our conference who were very sad because their favourite training was not available. If you book early you’ll help us to secure
