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).
When you are working in the area of mobile security, you sooner or later receive requests from clients asking you to test specific ‘Mobile Device Management’ (MDM) solutions which they (plan to) use, the corresponding mobile apps, as well as different environment setups and device policy sets.
The expectations are often high, not only for the MDM solutions ability to massively reduce the administrative workload of keeping track, updating and managing the often hundreds or thousands of devices within a company but also regarding the improvements towards the level of security that an MDM solution is regularly advertised to provide.
With this very blog post you are reading and a small series of future blog posts, I would like to provide some insight from my day-to-day practical experience with some of the most often used MDM solutions from a testers perspective.
We’re regularly asked to review IPv6 address plans from different organizations and I’d like to share some reflections from such a process currently happening. I’ve discussed a few aspects of IPv6 address planning before; those readers interested please see this post which contains some references.
Some years ago Christopher wrote two posts (2016, 2015) about the IPv6-related characteristics of the WiFi network at Cisco Live Europe. To somewhat continue this tradition and for mere technical interest I had a look at some properties of this year’s setting.
While thinking about the agenda of the upcoming Troopers NGI IPv6 Track I realized that quite a lot of IPv6-related topics have been covered in the last years by various IPv6 practitioners (like my colleague Christopher Werny) or researchers (like my friend Antonios Atlasis). In a kind of shameless self plug I then decided to put together of list of IPv6 talks I myself gave at several occasions and of publications I (co-) authored. Please find this list below (sorted by years); you can click on the titles to access the respective documents/sources.
I hope some of this can be of help for one or the other among you in the course of your own IPv6 efforts.
Today I am proud to announce that another paper of my former colleagues from Heilbronn University and me was published in one of the journals with the highest impact factor for Medical Informatics research called JMIR mHealth and uHealth. There is a reason why we published in this journal besides its informatics focus. The journal is an open access journal. That means that readers are not charged on a pay-per-view basis or other business models to access the full text of the paper. In return, the authors need to pay publication fees. In my opinion restricting access to academic research is not a way to go. I think this isn’t a thing we see in the security community often anyway. But this is and was the standard in academia for years.
