We are glad to announce the Windows Insight repository. The content of this repository aims to assist efforts on analysing inner working principles, functionalities, and properties of the Microsoft Windows operating system. This repository stores relevant documentation as well as executable files needed for conducting analysis studies.
Some of the content of this repository has been created in the course of a project named ‘Studie zu Systemaufbau, Protokollierung, Härtung und Sicherheitsfunktionen in Windows 10 (SiSyPHuS Win10)’ (ger.) – ‘Study of system design, logging, hardening, and security functions in Windows 10’ (eng.). This project has been contracted by the German Federal Office for Information Security (ger., Bundesamt für Sicherheit in der Informationstechnik – BSI). The work planned as part of the project is conducted by ERNW GmbH, starting in May 2017.
Chris and I will give a tutorial on the above topic at next week’s RIPE Meeting in Reykjavík. In this post (actually this will probably become a small series of posts) I’ll try to summarize some thoughts on IPv6 security in enterprise environments in 2019.
Dominik Phillips and I are taking part in a tour organized by Heise Security – the Heise Security Tour. We give a talk titled “PowerShell: Attack under the radar”. In this talk, we provide an overview of the architecture of PowerShell and show how attackers may use PowerShell for malicious purposes. We demonstrate PowerShell post-exploitation activities implemented as part of publicly available frameworks, such as Empire. We also discuss a security concept for defending against such activities.
You can find the slides of our talk here (in German).
This blogpost contains summaries of talks from this year’s TROOPERS19 Active Directory Security Track.
From Workstation to Domain Admin: Why Secure Administration Isn’t Secure and How to Fix It by Sean Metcalf
Active Directory is probably used in almost every corporation today to administer all kinds of Authorization, Authentication and Privileges. This means they are valuable targets for attackers, because once compromised they could do whatever they want. This would be the worst case scenario, right? Therefore securing AD is important and this year TROOPERS19 featured a whole track solely for AD Security.
Earlier this month I attended the Digital Medical Expertise & Applications (DMEA) 2019. The DMEA fair in Berlin (formerly conhIT) is the central platform for digital health care as it brings together companies of health IT, academic institutions, politics and healthcare delivery organizations in several format such as innovation hubs and talks during congress sessions as a part of the industry fair. I participated in a congress session about IT security in healthcare with a talk about medical device security and common security flaws in medical devices. Some of the aspects have also been covered in my talk at #TR19 .
As a follow-up of the very fruitful discussions between people from the car industry and medical device security folks in the IoT roundtable session from #TR19 I wanted to share my experiences and insights from the DMEA with you.
As promised in my previous post, I am back for an overview of the Troopers19 – Active Directory related talks… Videos have been published and it’s popcorn time… So if you are into stories about Kingdoms and Crown Jewels, grab your loved one [or a drink…] and turn the lights down low, ’cause tonight it’s “Troopers & Chill…”
Sadly, TROOPERS 19 is already over. I had great fun meeting all of you, helping you with your badge problems and seeing others hacking on their badges for example to get custom images on there.
With this year’s badge we wanted to give you something you can reuse after the conference, learn new things new build something on your own.
As promised in our talk Jeff and I would like to give you a short introduction into the badge internals. Along with this post we will release the source code for the badge firmware, the provisioning server and the schematics for the PCB.
