I had the pleasure to give a presentation at the Security Interest Group Switzerland Technology Conference about modern application stacks and how they can be used to improve infrastructure and application security posture – the slides can be found here. Besides seeing a lot of old friends, I particularly enjoyed a round table discussion on security integration into CI/CD pipelines.

After quite some time and work, I’m happy to announce the new release of the Linux Heap Analysis Plugins, which are now part of the Rekall project, but not yet part of an official Rekall release, so you have to grab them manually.
This release fixes several bugs and adds the following features:

IoT is everywhere right now and there are a lot of products out there. I have been looking at an IP Gateway lately and found some serious issues. The Busch-Welcome IP-Gateway from Busch-Jaeger is one of the devices that bridges the gap between sensors and actors in your smart home and the network/Internet. It enables the communication to a door control system that implements various smart home functions. The device itself is offering an HTTP service to configure it, which is protected by a username and password. Some folks even actually expose the device and its login to the Internet. I tried to configure one of these lately and stumbled upon some security issues that I would like to discuss in this blog post.

Last week (25th – 27th April), I attended the “Sicherheit 2018” in Konstanz which is the annual meeting of the security community of the Gesellschaft für Informatik e.V. (GI) in Germany. The conference is in equal proportions attended by researchers and people of the industry working in security-related disciplines which lead to lively and pleasant discussions conversations.

Lately I’ve been analyzing a .NET binary that was quite interesting. It was a portable binary that shipped without any third-party dependencies. I started looking at the .NET assembly with ILSpy and noticed that there was not that much code that ILSpy found and there were a lot of references to classes/methods that were neither in the classes identified by ILSpy nor were they part of the .NET framework.Continue reading
Stefan and I had the pleasure of joining a one-day closed workshop on Industrial IoT Security. As always, we ended up with plenty of new research ideas and great contacts. We hope of course to post on follow-up research, but in this short post we quickly want to publish our slides which contain our input for the workshop. We mainly presented on IT security challenges for modern IIoT environments and presented some case studies for successful hardening/protection of IIoT environments as well as security in IIoT product development.
You can find our slides here.Continue reading

During a recent customer project we identified several vulnerabilities in the VMware vRealize Automation Center such as a DOM-based cross-site scripting and a missing renewal of session tokens during the login. The vulnerabilities have been disclosed to VMware on November 20th, 2017. A security advisory for the vulnerabilities has been made available here on April 12th, 2018.
